I had Klaus & sons install my air conditioner and heater. After many quotes they provided the best quote. They were very professional, courteous & knowledgeable. Some the other quotes were extremely high along with aggressive sales tactics which I did not appreciate. Not Klaus & sons. They were in and out of my home very quickly.

Sometime later, I needed a new water heater. I did not think of them first. Again I called around & ended up buying one from a national dept. store. Even though I paid for delivery & installation, the guy who delivered it insisted upon an additional $500 to install. I sent them packing and called Klaus & sons. I did not think they did water heaters. I called & spoke with Jessie again. He said they do sell & install water heaters. He came right out & gave quote. It was installed by the end of the day. I wish I would have called him at the start. I always call them take care my heating & air conditioning needs. Their customer service is amazing, I can always count on their quality of work.

When we had a sink leak, I called several plumbing companies to schedule an appointment. Klaus & Sons were the only company to answer their phone and schedule someone the same day. The plumber was friendly and got the job done quickly. The price was good and we have called them a few times since.

Klaus and Sons Plumbing sent over Jake after our both our showers were having water pressure issues/leakage. I cannot be more pleased with the expertise, professionalism, and cleanliness with the work Jake did. Our issues were resolved in a promptly manner and he went above and beyond to ensure all my questions were answered.

Woke up on Christmas Eve and realized our kitchen sink was leaking and we had family coming in the afternoon. Called and got an immediate response and a 2 hour time frame for service. Received several texts letting us know the status and when Tyler was on his way. Tyler fixed the sink and was excellent about explaining everything that was wrong and what we needed to do. He was professional and got things fixed up very quickly. So happy with the service, honesty, and professionalism. Very thankful to have this company help save our holiday! Would recommend and will definitely use them again!

I've hired klaus and sons 4-5 times over the past few years. Each time I had called, the plumbers arrived on-time and we're able to solve my issues. While they are probably not the cheapest around, they solve matters in a professional way and always do the job right. They always have the right tools and make no excuses when challenges arrive. I would recommend them 10 out of 10 times. Thank you for being a fantastic company!

We had a large leak from our bathroom plumbing. turns out there were three. From the time I called the dispatcher on a Sunday morning, to the time Santino called was no less than 2 minutes. And he showed up in about 1 hour as promised, was 100% professional at all times and made sure to keep us updated, We have found our new heating/ AC and Plumber from this point on. Thank you Klaus & Sons you have earned our business.

Today Gene repaired our Amana furnace after it stopped working and showed an open pressure switch fault indicator. Bad timing since it's the coldest freaking day of the year. I called in the morning and he made it to the house by mid-afternoon and replaced the switch and tested various components to make sure everything else was working. Gene seems to have a lot of experience and he knows what he's doing. They don't make furnaces like they used to so unfortunately you need to have them repaired when they break. We'll call Klause again the next time this piece of junk malfunctions.

We had several jobs that needed to be taken care of sooner than later, and they were on time & courteous. Santino, the tech, did a great job, we fill very fortunate to have found a great company.

Updated August 28, 2016 - our water heater gave out and also discovered a mold issue too. Wes came out within 1 hour of my initial call and came back the next day to finish the job. Not only did he and one of the owners come out on a Sunday to replace the water heater, they helped to replace the drywall and patch the wall! Great service, timely and fair priced. We really appreciate their professionalism and the great work they did - seriously went above and beyond! Would highly recommend them!

Unfortunately I had to write a review because we started with a miscommunication and not a sp great start... But my fellow yelpers, was the company proactive to take care of everything professionally and promptly?
The technician showed up and took care of all the issues in no time and cleaned up and left! Gave me a GOOD and provided a quality work! Strongly recommend them...

I've used them twice, first time, great service, fair price. Second time, plumber had no people skills, seemed indifferent. Work was ok, price was overpriced. Only did half of what I wanted due to his over priced quote

Great and fast service! Best pricing I could find and service over the top! Will always call Klaus & Son for any plumbing needs. Thank you Andrew for your thorough service and friendly demeanor. Recommend to anyone!

We had our countertops replaced and a new sink installed as well and needed a plumbing company to connect everything up for us. The contractor recommended Klaus saying what a great job they do. We called them first thing in the morning and they showed up within 4hrs and at the beginning of the two hour window they gave me. The guy who showed up (Santino) was polite, professional, and did a great job. I would recommend I would recommend this company to anyone. My next plumbing job I will call these guys for sure!

We called Klaus & Sons in the middle of the day on Tuesday, hoping to get an appointment sometime this week to fix our stopped-up drain. Happily, they told us they could be at our house within two hours. About 30 minutes later, Andrew arrived and successfully fixed our problem. He was pleasant, professional, and knowledgeable. We have used Klaus & Sons for many years and have always been happy with them.

We recently needed plumbing service and I kept seeing the Klaus and Sons vehicles in my area. I decided to research them and give them a try. We'll, they did not disappoint. We had Tyler come by and service our home and he was AWESOME. Tyler explained everything and did not try to oversell anything. You can't ask for more when you are already thinking of how much everything is going to cost. We are glad we called. There is a reason why we see your vehicles everywhere. Thank you Tyler and Klaus and Sons.

Clear my external lines leading to city sewer AND my shower drain. This company is honest, experienced plumbers, professional, informative and goes the extra mile to ensure thorough work. I've used them twice now and have been 100% satisfied. If you want an issue done right and on the first visit, I recommend using Klaus & Sons plumbers.

Becca B.

08/01/2023 12:00:00 SA

Klaus & Sons is the BEST service out there! Had a major leak in my ceiling to where my ceiling was literally falling off. I called Klaus and they had someone at my place within a hour! The guys who came were outstanding! They spent hours working to find the culprit and finally did, and they fixed it on the spot! Amazing work!

We have used Klaus and Sons for 15 years now and would never use anyone else for our plumbing and AC needs. They have taken care of our three homes and four rentals with exceptional service. Wes came out to relocate plumbing so that I could install a sink in the garage. Like always the work was done professionally and in a timely manor. Wendy in the office is great and always gets us an appointment quickly. Thanks Wes for a great job. The sink installation went smooth and came out great with your nice work.

I was referred to them by Marquis Property Services (another awesome company) out of Highland, CA. It was very pleasant speaking to the staff. They set up a timely estimate appointment. Jesse arrived within the allotted time. He took the time to listen to me, review the information presented to him, inspected the job request and promised to send me a estimate.

I was elated to received the separated (although on one invoice) estimates for the things discussed later that same day. Wow, awesome.

Just waiting to review the estimates with my support team. I definitely would recommend them.

Buyer beware! A $10 capacitor and a $19 fuse for $190, can you say rip off!

Our AC went out so we call these guys, they say they can come out in a 1/2 hour but it will be $250 for emergency service, then we ask how much for them to come out in a day or two, they say we are all booked up for a week so it was now or never, this could be a lie or scam just to get the extra $$but that's ok we agreed to pay for the emergency service. When the tech gets here he shows me its the capacitor and he is also putting a fuse on it to protect it in the future, so I take the boxes while he is installing the parts, I look them up on the Internet, the capacitor retails for $8-12, the fuse is $18-21. So much to my surprise the tech tells me parts will be $190+the 250. After a long argument about pricing and retail vs. wholesale with the tech I tell him to call his manager as I wish to speak to him, long story short the manager decides to bill us $50 for the parts and says the high price is because they warrant their parts for 30 days and I won't have the warranty. What a load! Never use these crooks. I will be telling everyone I know.

We had a clog in the main line of our house. Klous and Sons came earlier than scheduled and cleaned out a big ball of hair. They were professional, timely and clean in their work. We had various plumbing issues because we have an older home and this company is becoming the one we rely on for our plumbing needs. Very much appreciate their professionalism each time!

We recently had a bathroom remodel due to a leak in the pipes. We don't know if it was the plumber or the remodel company that didn't check the hot/ cold water and when we tried to give our 2 year old son a bath we couldn't because the water was scolding hot no matter which way we turned the knob. I looked on line and figured out how to fix it. I was excited that I fixed it and got ambitious trying to switch the handle from the hot and cold water because again whoever originally put it together put the hot water on the side that shows cold and vice versa. Well I didn't have the muscle to remove the ring and ended up making our newly remodeled shower unusable. I wanted to call the remodel company to help fix it but decided to call Klaus & Sons and I'm glad I did! Jessie came out within about an hour and not only fixed the issue for free but also looked at our other bathroom sink and fixed the knobs to reflect hot and cold water appropriately! Jessie went above and beyond to help us out and we are so appreciative!

John D.

So friendly and easy to work with on our water heater replacement. Chris had a mask on the entire time and made the entire process so safe and easy for us. We called several plumbers and Klaus & Sons had the best price and better service than anyone else we've worked with. Would highly recommend. We're having Klaus & Sons service our HVAC next week as a result of this very positive experience!

Had a small issue with my irrigation but also needed some other work on my main sewer line connecting my washer and kitchen sink. I called another plumber out who gave me a price to replace things that didn't need to be replaced and quoted me over $8,000. My roofer happened to come by later in the day and he recommended Klaus and sons. I called over and they were out the next day. They assessed the situation and gave me some options for what I thought was very reasonable. They fixed the irrigation line that day and scheduled a few days later to address the sewer project. The tech was professional and did a great clean job. I would definitely recommend them and would call again.

In terms of plumbing needs, I lamented the closure of the local family owned plumbing shop of Mitchell's Plumbing business in Upland. I used them for many years and found them to be both very dependable with quality work and friendly customer service. My past experience with many large plumbing businesses is the amount of fees they charge along with the constant 'upsell' of their products when they arrive at the jobsite. Great news. I no longer have to worry with the services offered by another local family owned business, Klaus & Sons Plumbing. My elderly dad needed a couple of leaking water valves that provided water to the washing machine replaced. Pretty easy request. I made an appointment with Monica from the office and Chris was sent over at a mutually agreeable time to complete the job. Both Monica and Chris were friendly, professional and very responsive and the work was completed in pretty short order. No upselling and they even provided dad with a senior discount. Klaus & Sons is our new family plumber and I wouldn't hesitate to use them again, for myself or dad. Way to go Klaus & Sons!! You have the correct formula for continued success in the Inland Empire.

One more update, for Klaus and sons completely saving my day. Maybe I'm just a temperamental old Yelper here, but they really saved my $h!t, so they get my props here.

We had used a non-Klaus plumber to unclog a toilet a couple months ago, but the same toilet kept clogging. I called Klaus and Sons on a Saturday, not expecting same-day service. I had Brian, my Angel, at my doorstep 90 minutes later.

The clog ended up being way way more complicated than anticipated - he had to dig it out FROM THE OUTSIDE OF OUR HOME - how embarrassing! Brian was jovial and persevered through the worst of it and totally zapped his lunch break and was just so darn nice the whole time. He fought valiantly and finally won over the clog after an hour.

Klaus and Sons, now I'm loyal for life and I promise not to bellyache in the future. Thanks for sending Brian to save the day.

Following an annual termite inspection, notified of leak under house. Wes came out explained 1/2 galvanized water line leaking in wall. The job was completed in one day, following morning opening in wall under sink filled in. Skilled laborers resolved water leak and repairs needed; 8 tiles replaced on backsplash and filling in wall under sink. Clean up following tasks was a big help to me. I appreciated the caliber and demeanor of workers. Wes was up front, honest in process of fixing problem. Shout out to Wes! I highly recommend Klaus and Sons and will be using in future.

if I could add a sixth STAR, I would!
In the past 25 years my family(s) have relied on Klaus and Sons. Whether it's an urgent need, or simple service required, we get the same great service; from the time they answer the phone (live receptionist ) to the staff showing up to help. Thank you Klaus and Sons! If there was any other way to endorse you I would!

We've called Klaus and Sons twice and have been serviced by Michael( I think was his name) twice and he is great. Very honest about what does and doesn't need to be done. Definitely never calling our old plumbing company again. Klaus and Sons is our new go to!! Really recommend them especially Michael!

Kelly N.

6/15/2020

We have worked with Klaus and Sons for the past four years. Jobs ranging from a small drain clog to a major sewer line replacement, and everything in between. They are always professional, courteous, punctual and reasonably priced. I would absolutely recommend them for any job, large or small.

This is an update to my previous review. I received a call Saturday morning from the owner apologizing for no one returning my calls the night before. There was some misunderstanding/ lack of communication with the answering service. He offered to send us a gift card for future service, but since we still hadn't had our issue resolved, he sent someone over immediately - they arrived within 20 minutes. They did a great job replacing the water heater and dealt with a couple other issues, and ended up giving us a substantial discount to compensate for the night before. Thank you so much Klaus and Sons!

............

How can you claim you're a 24 hour service and not return phone calls 24 hours? I called at 7:30pm on Friday regarding a broken water heater flooding our garage and was transferred to the answering service. They took a message, and an hour later I still hadn't heard anything. I called again and the answering service said they didn't know when I would receive a call back. How is this 24 hour service???

I used this company again to replace a Mixet shower valve with a Moen. The technician I used for this job as well as installing a water pressure regulator recently was Jason who is great to work with and did a very professional job. They are my go to plumbing company.

My grandma has been using Klaus and Sons for years and years! She won't trust anyone else to do that type of work on her home. So when I had a clogged drain line, I knew exactly who to call! I was given a time frame that worked for my schedule and Tyler showed up promptly. He was very thorough in explaining what the issue was and gave me some tips to keep it from happening again. He got the line cleared instantly. He was kind, courteous and professional. I am beyond impressed with Klaus and Sons and will be a life long customer just like my Grandma. Thank you guys for a marvelous job!

Summer 2017!! After 15 years, my HVAC decided to die. Klaus & Sons were the only ones to answer the phone! A live human to talk to is a HUGE plus! A good first step. A technician came out and gave the straight story, no bull! I'm familiar with AC systems so I understood the language he was speaking. He explained what was going on in simple layman's terms. Ultimately, I made the decision to not try and put my old system on life support. Technology has changed and it was time to keep up. Long story short, over a few/couple of days, they removed the old system, installed the new one, sealed everything, refilled my attic with insulation and cleaned up after themselves! I have never had a better experience with a contractor than I have with this one! It has been a few months since the install and I am still a very happy camper!! Thanks Klaus & Sons!!

Patrick B.

We had two toilets and a shower flooding. Klaus responded quickly and resolved the issue.

David D.

05/10/2022 12:00:00 SA

We finally decided to go ahead and replace our entire HVAC system, which by now was a patchwork of technologies, phases, and installers going back to 1988. We chose Klaus and Sons, based on the recommendations of all the various other first-class design/builders, electricians, and painters we have worked with over the years. In the end, it was the opinion of all these well-known first-call contractors that sold us on going with Dan and K&S. The crew was a superb group of pros with great senses of humor, and they developed a genuine love of fresh Peet's coffee twice a day; it was the least we could do. We now have a modern state-of-the-art SEER 16 system, with a heat pump where it made sense and a gas furnace where it didn't - the expertise and attention to detail brought to the project by Manny and his crew - along with Gene and his crew, was everything we were told it would be by our portfolio of other contractors. Every inch of our system is new and clean, and as we look ahead to another summer that might be as tough as the last few in terms of heat and smoke, this next summer will be one like we have never experienced: as comforatable and healthy as we can be during the heat, and worth every penny getting there. As an independent contractor myself for 40 years in a totally different line of work, we can't recommend Klaus & Sons highly enough - Dan was rock-solid with his bid and suggestions, and the crews were just like mine; first-class, and fun. You get what you pay for, and we have to say that after the job was completed we couldn't be happier.

David M.

Does not unclog the line the plumber says he cleared it collects from credit card gives you NO warranty on their work so if they have to come back on the same day for the same issue they will BILL you again so now there are 2 invoices for the same day for the same problem

Chris H.

8/25/2021

Chris came over to help diagnose a smell coming from the bathroom. He found the problem and got to work. He was very polite and professional. Fixed the problem and cleaned up the mess that we caused.

This is our first time calling Klaus & Sons, I did so because of the reviews here and on FB. Great work and people. We will call them back!

Anthony C.

12/21/2018

We have used Klaus & Sons several times for for different issues and Fred has always been our plumber.

Service: Excellent, professional, and friendly

Price: Very reasonable compared to many others we even received a preferred customer discount today, which was a great surprise.

Timeliness: Has always been on time and gets the job done in a timely manner.

Left the job: Clean

I would recommend them to anyone and will be using them in the future when needed.
Thank you Fred.

They are the best around, I had about 5 other companies come out and give me estimates. Our central AC wasn't working form the moment we moved into our home last year. They are fast friendly and affordable. They exceed in qualifications and offer the best units. I would definitely recommend them

Kathy T.

4/28/2022

Chris came to discuss a whole house water filtration system several weeks ago, then never called back with a quite. I sent a message to the office and they said they would remind him. No word. I would have appreciated even a text that said they couldn't do it at this time. Disappointing.

Isaac J.

04/11/2018 12:00:00 SA

They are a JOKE. I called for a simple service call. Their so called receptionist took down my info and booked me for the following day 3-5 which is the norm. Wife got off work early to meet and greet their worker. Well 430 comes around no show . I know im 30ins early anyhow i call them and ask if they are near or just to get a eta. Lol. Receptionist remembers our convo the day before but never took notes. So when i called we went over the hole spill again. (She even told me now im at my desk).WOW! So there so called manager gets on the phone with me. Only to start all over agian. Grrrrrrrrrrrr not recommended.

Al M.

11/19/2018

Had a leak in the bathroom, when I called at first the receptionist told me they were busy. When I explained the urgency she did everything possible to get someone out to my house. She worked some magic and told me someone would be out to me within the hour. Sure enough Andrew arrived a little before the hour. Andrew took care of the problem and made some suggestions regarding my fix. Andrew provided me several options. Andrew was professional and he didn't give any vibe that he was scamming me. I felt he was honest and spoke highly of his company he works for. Would recommend Klaus and Sons for their service.

Joyce C.

02/02/2021 12:00:00 SA

Needed some plumbing repairs. Was able to use their website to make the appointment. Chris showed up on time, with appropriate face covering. After assessing the needed repairs, gave me a reasonable quote and made the repairs right then. Would definitely use Klaus & Sons again.

Mike M.

7/23/2019

I contacted Klaus & Sons because my air conditioning was not cooling. I set up an appointment and received a call the day before to remind me. I also received a text in the morning on the day of the appointment to let me know someone was on their way. Gene showed up on the day of the appointment. He explained what he was doing and why. I asked for his opinion on a couple of things and he was helpful. The work was done quickly and I was very satisfied with the service and communication form Klaus & Sons.

Carlo G.

05/08/2020 12:00:00 SA

Tyler did a great job! He was early for his appointment and called ahead to ensure that it was okay with our schedule. Very through, respectful and clean. He cleaned up after himself and left areas spotless. We ended up needing a new pressure regulator and installed our new kitchen faucet. Thanks Tyler.

Allison G.

05/07/2022 12:00:00 SA

I called on a Saturday and they were able to come out that same day. Sal and Andrew were friendly and helpful. They fixed my clogged sink quickly and efficiently. And for a reasonable price. With no upselling. Thank you Klaus & Sons. Next time I have a plumbing issue you will be the first ones I call.

Simon B.

03/01/2021 12:00:00 SA

Chris at Klaus & Sons is absolutely the best! He is prompt, communicative, reliable, friendly, and professional. His work is incredibly high quality and he is honest almost to a fault. It is so comforting to know I have a go-to plumber that will always get me sorted out quickly at a fair price. Thank you Chris for always doing such an amazing job.

Thom C.

9/19/2021

Sal at Klaus & Sons is our go to guy for any Plumming problems. I won't get into the very long details but our house is built in 1952 and therefore we have had a lot of plumbing issues in the past year. Sal has been amazing and fair and honest. They always answer the phone which is unusual for plumming companies and they always have someone available within the day. Dealing with plumbing issues is expensive and no fun but at least I have a company I trust and can get ahold of.

Klaus & Sons have been my Go-To Guys* ever since inheriting them when moving here first as a renter 18 years ago. Wes the Wonder Plumber, Gene & Jesse the Awesome A/C Guys have always been prompt, efficient and effective in addressing whatever the issue. THANK YOU all!

Requesting just a QUOTE is FREE on YELP but they wouldn't do it over the phone for a homebuyer even though I just have a few things specifically fixing a broken heater and adjusting water pressure that is too high. Literally TWO THINGS you quote people for FREE on Yelp, but you want to send a plumber and an HVAC person at a cost just to give me quote for problems I already know I have.

Klaus & Sons: I have been very satisfied with them for over 30 years. I was glad to see the talent, fairness and service as well as fair price remains. Cris, the third generation quickly and economicly repaired and replaced a bath faucet for me. Thanks!

I was in the market for a new air conditioner & furnance replacement. After receiving 5 quotes my mind was stuck on the 2nd quote I received which came from Klaus & son thru Costco for many reasons. 1)No pressure or timeline for price to expire 2) one of few who was an actual tech & not a sales rep that shows up 3) did not degrade any other companies. During the install I had a few issues come up and each time I thought I'd get push back or I'd have a fight on my hands, NO that wasn't the case. I have to say everyone whom I dealt with was professional. I do highly recommend klaus& son even if it's just to give you an estimate. Thank you....John, Kevin, Junior and Dan

You don't find customer service like this anymore so hats off to you Klaus & son (Dan)

I called mid morning and a plumber was ready and available, but I had another appointment to tend to. The dispatcher accommodated my time preference and the plumber was there waiting for me on time. He was quick with the work and explained every step thoroughly. He explained what I can do to help prevent a back up again! I will definitely use Klaus & Sons again.

Santino showed up on time and repaired the water connection to my refrigerator. He was courteous, friendly, and most importantly, efficient. Santino had previously been at my house 2 weeks ago to repair an irrigation pipe that was damaged when my house was painted. His work then was just as good. I direct all my plumbing, air conditioning, and heating work to Klaus and Sons. The secretary who answers the phone at Klaus and Sons is quite nice and very competent.

On Thursday evening we noticed our home was backed up, we have a big family and everyone either had school the next day or had to work, having to wait for the next day to clear the line was not an option. I called various 24 hour plumbers and either they didn't have a technician available or were ridiculously expensive, I called Klaus and Sons and they were very attentive over the phone, Chris responded within 30 minutes to my home, after hours service was very affordable and he was able to clear the main line with the camera attachment, thus not needing to snake it, he could've charged me the price of cost to snake it but he left that decision to me if I wanted snaked it would be extra or leave it as is (no need to snake, main line cleared) and only charged for coming out after hours and using camera. Chris was very honest and a pleasure to discuss future plumbing work to clear roots in sewer lines, will definitely be using Klaus and Sins from now on. Thank you Chris

Five stars for sure.

I work for a church and school, and we had a plumbing emergency that needed to be done after hours, so we didn't disrupt our programs.

We looked at multiple comapanies.

Klaus and Sons, was amazing
They were professional and prompt.
They brought out a team after hours and found the problem and fixed it right away. We really felt like they went above and beyond, and we will definitely use them again if we have another problem!

Thank you

Warning, Only warranty work for 90 days!!! December 2019, had Klaus and Sons fix a simple leak coming from the drain in our tub. By July 2020, it leaked again from the same place. I called assuming they would stand by their work and fix the issue, instead they informed me they only warranty their work for 90 days...what's the point of having a warranty if you're only back up your work for a few months?!?!? Beware!!!

So we've had KSP Do a few things around the house whenever we've have an emergency. Typically I do all my own work and I'm very picky but when I do call a plumber and need something fixed fast, it's KSP. Had my water pressure regulator go out they were able to schedule me in for the next day Fred arrived on time we talked through the situation. We went over what I had experienced and what I checked. He verified the concern and within an hour he had my new pressure regulator back on and had us up and running. Fred did a great job explaining everything, was tidy and courteous.

Got a quote from John to replace our AC system right after our scheduled inspection appointment. He is very knowledgeable and steered us to the right equipment based on our use, without overspending on the bells and whistles, and he is not pressuring us to make the decision. After we decided to go with Klaus & Sons, John was able to send a crew for the installation within 2 days, and he sure picked a good crew to work on our unit. Kevin, Tom and their assistant showed up at our house as scheduled and did a wonderful job on the installation. They took care in protecting the work areas, did a professional installation, started the unit and adjusted it to run perfectly. All the rooms are now cooled down evenly both upstairs and downstairs. These guys did a great job that we even recommend them to a few friends and co-workers.

Rebecca W.

8/24/2018

If it was possible to give zero stars, I would. Scheduled an appointment for an estimate to repair my AC. No show, no phone call. In any circumstance, that is poor customer service and just plain rude. I've never posted a review before, but I am beyond displeased with this company. Fortunately there are plenty of other companies that I can give my business to.

Jessica H.

My mom found Klaus & Sons through the nearby Costco and was extremely satisfied with their service!! Dan was extremely knowledgeable and helpful in the estimation process. He was open and honest about all the options available to us and my family ended up very pleased with our choices! Additionally, all of the employees who worked on upgrading our AC system were extremely diligent and pleasant. They were able to complete all the work in the projected amount of time. I also want to add that Dan was very quick to respond to all emails and inquiries my mom had. Overall, a really great experience for such a big job and we would highly recommend them to anyone.

Klaus and Sons installed a new air conditioner system for me in 2012. They were very nice and professional. This is a family owned business. They provided great service and did a great job. They even sent a card thanking me for the service and included a coupon.
I did not know that I was supposed to have the unit serviced twice a year. It got blocked this year. They sent a very nice man, Marino to service the unit. He is very nice and polite. Cheerful man. He even explained to me the frequency of changing the filter. I thought it was twice a year lol. I think the last time I encountered such nice service was 2012 when they installed the unit. You don't see such service very often anymore. I highly recommend Klaus and Sons.

08/10/2021 12:00:00 SA

I called Klaus and Son's because we had a couple shower-heads that started leaking. Schedule and appointment for a 2 hour period. Wes, the technician, called as he completed a job earl and asked if it was convenient for me to come early. It was and I very much appreciated that.

Wes took a look and the issue and parts required, ran to the shop to gather the parts and came back and fixed the issues quickly.

He was clean, friendly and professional.

I highly recommend.

In the midst of the hot spell when everyone needed assistant they were able to get to me within 24 hours. My wonderful technician, Gene, was early showing up. Talked me through everything he did. Was upfront about the cost. And I am basking in the coolness!

I found myself needing help on my heater ASAP and the quickest appt I could get was the next day and I could understand seeing that it has been chilly and it's not only about me like I sometimes think LOL. The gentleman came out the next day on time and was as nice as ever and explained everything to me. This company is stellar!!!!

Imdescovered a leak under a bathroom sink last weekend. By Monday at 10:00 the repair was complete. Very quick response. No hassles and the cost, in my estimation, was responsible. I also inquired about another very minor problem, and after discussing it with the plumber, discovered that the cost to repair or replace was not worth it. This is not the first time I have used them and They have become my preferred choice. Very friendly, courteous and reasonable.

Just got my AC fixed by Klaus. I called today (Monday morning) and was first told that the next available appointment was on Wednesday ( I had called a few other places and everyone was booked solid as well), when I expressed that I was not able to wait that long since I have a 3 month old baby at home, they said they will squeeze me in and gave me window between 12 to 5pm. I know it's a big window but I was desperate to get the AC fixed due to the 100 degree temp. Mario showed up around 4pm and my AC up and running in about 30min.! I had a blown compositor and blown fuse. At $285, they certainly arent cheap, but I'm glad I called them! I would recommend them to anyone in upland and Rancho area if they can bare with the price.

Last week SCE shut off 32 homes because of a auto accident around midnight on Friday. We recieved message that service was restored but that was not the case. Saturday we contacted Claus & sons whom quickly responded & determined a electrical spike damaged our a/c unit.
Monday was Memorial Day so our unit required new main control board @ thermostat that needed replacement. It was ordered and arrived on Wed noon. they came to the house the same day & had it running by the afternoon. Despite the 3 day weekend they did a great job.

8/14/2023

They have done acceptable work for us on normal times.
Our A/C stopped working with recent 100 Degree weather.
Theg gave us an appointment one week out.
To survive the heat, we got some one else to fix. but kept the appointment for an inspection.
in a week they inspected the unit and verbally told the Tenant everything is ok and changed my Credit Card $203.00 without issuing an invoice.
Is this an acceptable way ?

Great service! Woke up Saturday morning to no hot water. Made a call to Klaus at 7am. A new hot water heater was replaced by 10am.
The service was friendly and professional. We have used Klaus before and would definitely recommend! Try them first before calling anyone else.

Sorry this post is so late, very busy week. Plumber came out last Friday to help with a plumbing problem I was having with a bathroom remodel. The gentleman's name was Wes, he was very friendly, helpful and professional. Assessed the job gave a price and completed the job in no time. I have a couple of more plumbing jobs in the future and I will not hesitate to call Klaus and son's. Needless to say I'm very pleased with honest reliable work. Highly recommended.

Marino came out earlier than the promised time period in a pouring rain.
Very professional , located the problem and showed and explained it to us. Only $13 over the minimum appearance fee which was great, considering with a non working furnace could have been a lot more. No up-selling which was a very pleasant change from other companies I have dealt with. They also do air conditioning and plumbing , so needless to say, they will get my call if problems on these systems happen. Thank you !

10/22/2020

We loved the fact that Chris (grandson of Klaus) showed up in a mask. He was great! Very professional, knowledgeable and super nice. I've always had a great experience with Klaus and Sons. My brother has them on speed dial for them to work at his business The Christmas House Bed and Breakfast Inn and they always come right away. Can't say enough of good things on their behalf!

John came out and gave us a quote to replace our AC/Heating system and all of the ducting. John came in and examined our house and, at our request also added two new returns to get the air moving in the house. He is very knowledgeable and easy to work with. He gave us a quote of 4 days (the first day for an asbestos company to remove our vents) and he wasn't kidding. The crew came in and worked like maniacs and got our entire system upgraded and installed new equipment. I am used to companies doing the contractor shuffle where they come one day and are gone for two and show up for one day etc etc. Not this company. They showed up on time and worked entire days getting the job done. I would recommend this company to anyone who needs quality, professional work done. Thanks to all.

Ann S.

05/07/2018 12:00:00 SA

Tyler came out to our house and was awesome. Spent his time working hard, and explaining the issues. He diagnosed it and prescribed the necessary fixes. They are on the pricier side but in my opinion you get what you pay for. He was on time and courteous. We actually ended up getting a second bid for some major work that Tyler prescribed because it was expensive and i wanted to see how another company came in at. The bid we got from the other company was half of klaus's bid. With as much money as the repair costed, I couldn't leave that kind of money on the table so I went with the other company. I may regret not using klaus but only time will tell

Our dishwasher started leaking right in the middle of a party. We got Ryan to come and take a look at it. He arrived a bit late due to an earlier job that took longer. Ryan found the cause of the leak and took care of it quickly. Having the tools and knowledge makes a big difference.

I contacted Klaus & Sons for a bathroom repair job involving my bathtub/shower. Chris responded the next day within the scheduled appointment time. I found him to be extremely pleasant, professional, and wearing a mask, which I appreciated. He immediately assessed the repair job and provided an agreed upon repair cost. The repair was completed to my satisfaction and within a reasonable time frame. This was my first time using the services of Klaus & Sons. I would use them again and recommend their professional services.

My shower handle broke off - Klaus and sons office responded by having Chris show up the same day I called in- what amazing service. Chris was professional, friendly ,polite ,clean , COVID safe and aware. Repaired the shower handle even went out of the way to get us an additional part - then checked the water pressure- (only was at 120 ouch! Normal is 75-80). which proves we did need a new regulator as house is 40+ years ( north upland location) thank goodness he had one in the truck ! Klaus and sons will now be my go to place. Thank you Chris for the extra wonderful service and explaining the issues clearly. I Highly recommend! Chri

Our old furnace was out and we called several places, but only Klaus & Sons would send someone out immediately on a very rainy and cold day.
Monica's communication was super clear and prompt. Fernando was super helpful and explained both the immediate issue and the long term status of our old unit.
The price was reasonable and there was no upselling. Paid by credit card and the house is warm again.
I'll be keeping Klaus & Sons' number handy! I highly recommend that you do too!

Heather and Sal are exceptional delivering customer service. We've used Klaus & Sons many time. Heather and Sal are always pleasant, professional and thorough. Covid compliant. Trustworthiness and customer service is important to business success. If you want efficiency, honesty, and a good attitude, you won't go wrong with Klauss & Sons.

We ended up with a clogged sink the day before traveling traveling for family vacation. The day before coming back we called Klaus & Sons plumbing and were lucky enough to scheduled for them to come out the next day. It was a blessing that SAL came out to inspect. He was very knowledgeable and patient with the clogged drain situation and applied effective techniques with a successful result! Long story short, he was able to get the pipe unclogged! Were so thankful we switched to Klaus and Sons, they keep it friendly and do it right. If you're on the fence about a few companies, I'd go with Klaus & Sons.

I needed an emergency gas shut off valve installed at a commercial property. I called klaus and sons. They were quick to give me an estimate and even better, got the job done for me at a fair price. Jesse was super helpful and even sent me photos once it was completed. I would definitely recommend klaus and sons. Great customer service all around from the front office to Jesse.

I was a repeat customer. I had a leak outside on a 3/4 PVC line feeding a hose bib. The service was prompt and courteous. The price quote was $450-$1050. Neither of us knew the source of the leak at the time of the quote so I was willing to accept his broad ranged estimate. The leak was 12 inches down in open dirt, minimal in my opinion. The repair consisted of 1, 3/4 pvc elbow. I thought I would be charged the low end of the estimate. The bill was $950.00 which I thought was beyond excessive but offensive. I have never written a yelp review in my life but thought this was an extreme price gouging. Daryl Koops-Upland CA

Not only did I have to call twice, but the man who returned my call let me know that there would be no chance in hell, as if I needed to hear that on a day as hot as this, that an appointment could not be made for two weeks. Why the hell call me in the first place? Why didn't the call center field this? We all could have saved valuable time!

David and Gene came to service my AC. After having another company come out and take a look they weren't able to fix my issue. Said n Gene came out and had it fixed in a little over an hour. They were honest and up front, they didn't try to up sell me on anything. The explained the entire process. I would definitely use them again. Fair n honest is rare now a days

We've used Klaus and Sons twice for plumbing concerns and were completely satisfied. Theya re so easy to reach and schedule with. Last year they replaced the main water valve on our home--it was an urgent concern and they responded quickly and fixed it promptly. Today, Fred came out and replaced a toilet. He arrived promptly, and did an excellent job. What more can we ask for?

Andrea M.

7/16/2020

I called with a leak in my main water line from meter to house. They were out within the hour and gave me a VERY reasonable quote. I accepted and they began work immediately. They were very conscientious about my yard with putting everything back as close as possible, when you need to dig and lay 70 feet of pipe. I was given a second hose bib off my water softener so I can wash my car with soft water and then installed a cut off valve for my irrigation separate from my house! Was super cute excited about those 2 added features! The crew was very professional and hard working. Whew. They were fast and efficient. I will definitely call this company again for ANY plumbing needs. I found out the also do heating and a/c. I will call them for that too. I met both Klaus & son. Super friendly and honest. 10 stars!!!

Carl T.

05/11/2023 12:00:00 SA

Five stars are not enough. Making this short. Klaus & Sons referred by a morning coffee friend. They installed a new system for him in last summers heatwave. My AC went out last summer, both systems. Called 3 companies. Two were no shows, one was clearly after my wallet.
Last winter our furnace died. 20 year old unit. Fernando resurrected it and checked the ac. Had to hold off of the ac repair because it was too cold to add coolant, if needed.
He came out today, got the ac going. He checked the second unit, on the roof. Last years tech, the only one that showed up, said the unit was dead and a complete replacement called for. Fernando spent some time diagnosing the problem, got it going. He was clear that the very old unit will not last forever, did not make empty promises, but advised to use moderate cooling and there was a chance of a few more years. My wallet is still 90 percent full.
Give Klaus &Sons a call if you need hvac help. Six super large stars.

Basic slow draining drain, not even a full stoppage. Technician wanted me to sign invoice before he even started service. Almost $400 later he didn't even put my sink back together properly. Didn't find anything but it appears to be draining. Wtf!? Not happy. Should've called Mike Diamond.

Followed covid protocols, came over very quickly and promptly did the estimate and then the actual work. We needed two faucets installed and a rusty spigot replaced. Friendly and efficient plumber. Cheaper than the handyman service I was considering. Will look to them whenever we need other plumbing work done.

7/29/2021

We've been having problems with the compressor and condenser for the past year, and David came out on short notice (about a week) to take a look at things, and help resolve our problems. After some dialogue, David recommended replacing the unit, and we discussed our options and timelines - and have a solid plan of attack. Really happy with Klaus and Sons continued professionalism, and will continue to leverage them in the future.

we had a plumbing emergency. they came, used cool technology to evaluate, told us what needed to be done, and fixed it. they had to dig through concrete and it seemed expensive at first, but then i consulted with my friends who've had similar problems and it turned out that in comparison they were much less! yay.

11/22/2021

Awesome customer service. Came out immediately and completed job same day. Original rep called for assistance to insure challenging job was correct. Our first-call plumber from now on for sure!

I have used Klaus and Sons for plumbing (I live in a 105-year old house), laying a water line and, most recently, installing a new gas line. I have always found their work to be the best I know is available in my area. On a couple of instances, I chose other local plumbing services for simple repairs, thinking I could save a few dollars, but most of the time, I regretted that decision.

Jeremy K.

1/31/2022

After hours heading into a weekend, we called when problems with our gas suddenly occurred all over the house. A technician arrived within 10 minutes of our call, did some quick problem-solving, and had everything working again within the hour. We've had similar fast and effective service for plumbing issues in the past. Thank you Klaus & Sons!

Mark P.

7/26/2021

We needed to replace our tankless hot water heaters. We made an appointment for someone to take a look and give us a quote. They were on time, friendly and very knowledgeable. We received the quote the same day.
We scheduled the work to be done the following week, again they were on time and friendly. They were very conscientious and took precautions to protect our floors and interior finishes. Once completed they cleaned up thoroughly and provided us with all the details we needed to know.

This is not the first time we have used Klaus and Sons. They are always fair, friendly and knowledgeable and I highly recommend them.

Diane B.

Last week I had my furnace, air conditioning and water heater replaced by Klaus & Son. Great job!!!! I so pleased with their work. KUDOS to: Rick, Daniel and Charlie who replaced my furnace, air conditioner and water heater. They were all very knowledgeable, courteous and took pride in doing their jobs well. I was pleasantly surprised to find they actually went the extra mile to be sure the Units would function optimally by correcting my AC vent to the outside rather than leaving it as it was, and they also replaced some plywood that added to the strength of the stand the water heater and furnace sits on. I would definitely recommend their services to anyone needing plumbing services.

Derek S.

6/22/2023

Quoted me just under $4900 to run 25' of copper pipe. No breakdown of quote - just a number seemingly pulled out of thin air. When I queried the price the response was 'material costs have increased'. 3/4 copper is around $10/foot, that leaves around $4600 for half a days labor. Yes, running a business has overheads and other costs, but not $750 / hour for labor.
I ended up going with another company and the final cost was $1250, which is still pricey but not blatant gouging.

Marian S.

12/14/2018

Sal, the plumber arrived on time and provided efficient, effective service--replacing nearly all the parts of our toilet. Very happy with this company and serviceman.

Klaus's n sons were honest people. Wes is great and back up his work . I have used them for more than 15 years.
They are the first plumber I call always . The owner Jessie is very professional .

Karen M.

08/11/2022 12:00:00 SA

The plumber was respectful and very helpful. The cost to put a snack down one drain with a plumber in my home for maybe 30mins was $179. The owner said they waived the after hours fee but it did not feel like that. Then to go into my bathroom and see that he put the overflow drain back on with the drain access on the side not the bottom was frustrating. I want to call and have him return but it is just easier to do it myself.

Kevin M.

7/27/2020

Thanks again for the quick, expert and reliable help with the drain replacement; rapidly and well done, plus a quick troubleshoot on another issue. Wes is awesome. I don't have to worry, just call Klaus and Sons.

We will not use any other company for all things plumbing and HVAC related. We have had a number of issues in our older home and we can always count on Klaus & Sons to fix it right and at a fair price. They also get to use right away. We've even had them remodel one of our bathrooms and it turned out beautifully. I would give them 6 stars if I could. THE BEST!

Bryan S.

7/31/2022

I had 2 different plumbers replace some sinks for me. Tyler replaced 2 sinks and 2 faucets at my home and one faucet at my office and did a very nice work. Sal replaced a sink at my office and also did very nice work. Sal made sure the sink in the office would come out very nice and spent extra time to make it work. If you need a plumber ask for Sal or Tyler at Klaus and sons.

There was a leak behind the wall of the bathroom. I open the wall, closed the water. Visited Klaus, they came fast and made a Profesional fix. However I found them rather expensive.

We had Klaus & Sons come out for a clogged drain and install of a kitchen faucet (which I provided). They did a great job, and everything works well.

I called Saturday morning. Spoke to a lady and I gave her my information to make an appointment. Like a dumbass I waited all day and never got a call or text back from anybody. I specifically asked if they work Saturdays or not. She said yes. Never again wasting my time with this company. I could have been at work.

Edit.
Gave them a chance again. They got there early. Fixed the issue quickly no questions asked. Happy camper

Our main line clogged backing up sewage into our downstairs toilet and shower!

I will spare the gory details. After calling Ryan arrived in 10 minutes diagnosed and resolved the issue in 10 minutes! After police and firefighters plumbers are my heroes.

Came out on a Saturday with only a moments notice. Had to unclog a drain in a home with plumbing so old they had to make sure they did not crack the ancient pipe. Super efficient and with great success. And a very pleasant plumber. Totally reliable and would highly recommend. Thanks

Had a leak under my sink. It was bit of a puzzle trying to find it. Phil is the best. He looked, tested, went under the house, felt for moisture on all the pipes. All were dry but water was apparent! Finally found it! It was the caulking around the faucet plate. Was worn down on the backside of it. Water leaked through there over time. The floor under the sink had rotted away from moisture. it crumbled from the water. Phil dried everything out and applied new caulking. THANK YOU PHIL!!! Still have to repair my floor but no water!!!

I been a Klaus and Sons customer for many years. They have done many services at my home. I have been satisfied with all the jobs.
Unclogging drains, relocating the water heater, replacing a toilet, locating a gas leak, and the last service was replacing the kitchen faucet, and minimizing hoses under the kitchen sink. This last service was completed by Brian. He was very personable, and understood what needed to be done. He had no problem with me asking questions and explained in detail the process of this service.

We had been having a confounding issue related to our heating system. We received what appeared to be a solid diagnostic and a quick repair with a recommendation for further work which we are considering. This is our 4th set of work completed by this company and we have been very satisfied. Each time we have received service identical to my initial description. Bottom line, trustworthy and skilled.

A technician came out from Klaus and Sons to tune up my AC. He was very thorough and showed me in several ways that my system was damaged (leaking oil, cracked motor, etc.) The install crew put in my new system and might have been in too much of a hurry. The next day I called with some noise concerns. A technician was dispatched in less than an hour. He also was very thorough, and he spent an extra three hours on warranty work. He solved the problem. I was extremely pleased with his work. He was unusually conscientious! The moral of the story is that Klaus and Sons backed their work and made it right for the customer, me.

Had their team install a new HVAC system, air purifier and water heater. Their estimate was competitive with others we received.

The team that came out was friendly, professional and clean. Every day, the team lead (I believe his name was Daniel - loved him) explained to us what they were going to accomplish that day and at the end of the day, they reviewed their work with us. Each day, they cleaned up after themselves and left the area spotless. They moved the entire HVAC system up into our attic. Now, I don't know the first thing about HVAC, but when I looked up there, it's beautiful. :) We've had the system a week now and everything works very well. Hot water heater is also running great.

I'd recommend Klaus to my family (actually, my extended family has used them in the past) and friends and will be a return customer should we have any other needs.

Our kitchen sink backed up late last Friday night so I called Klaus first thing Saturday morning and Santino called me back within 10 minutes. He already had several emergencies to respond to but said he should arrive our home by 3 that afternoon. Santino arrived early at 2:40 and followed Covid protocols and cleared the clog that was more than 35 feet down the drain line ( I had tried my 6' snake and plunger but they were useless with a clog that far down. I would have needed the 100' commercial snake that Santino had). He was done (and cleaned up the area around the sink) by 3:30. Santino was very knowledgeable, professional and very pleasant to work with. Would definitely recommend this company & Santino.

Chris was amazing! I had a slab leak in my kitchen and he was able to come out right away, less then 2hrs after I called. Diagnosed the problem immediately and said he could have it fixed next day. About an hour after he left, they called and asked me if he could come back same day and fix it. I was elated. Chris came back very quickly and even though the leak was a little worse then he expected once he got everything opened up, he fixed it perfectly. He also didn't charge me more then the original estimate, even though it took a bit more work to fix. Excellent service, very professional, was COVID compliant the whole time, and very reasonably priced. He answered all of our questions no matter how big or small and was so knowledgeable about everything. We definitely will be using this business and Chris for any future need. If you're looking for excellent service from someone who knows what they're doing and won't rip you off, you found the right company.

I had one of these guys come out to check the a/c on my new house. He came out and charge $100.00 to look at it then charge me an extra $40.00 which was never discuss over the phone that i maybe charge additional fees.To tell me everything look fine all he did was add some chemical to my a/c which he did not even explain to me, then on top of that put black marks from his finger all over my NEW PAINTED WHITE WALLS!! plus after he said it should cool down after I hang curtains he left with a bad attitude customer service was very, very horrible . After that a few days later I went to put my a/c on my house read at 85 degrees felt like a oven, after 2 hours it still read at 85 degrees and having two small children, one i mite add which is a 8 months year old suffer in the heat i could not believe my a/c didn't work I had to call another company to come out and fix it. Now my house stays cool after going though all of that i shouldn't have to call another company to do the job they were suppose to do. Sorry but they just want to take your money.

consistently excellent service. They've been servicing my AC and heat for years, very happy with them -- now put in new AC and had emergency sewer and water pipes work -- fast, polite, fair. Not cheap, but the price is fair and the office as well as all the workers are helpful and actually try to find various ways. to save money, giving clear options.

This company is horrible!!! We had our a/c installed 6 years ago. First of all they did not connect the gas line and left my house with the gas line on. I called the owner and he was very apologetic and sent Gene out to fix. I swore I was never going to call them back out! However, the warranty was amazing and we were having a problem. The warranty stated that it was for 10 years all parts warranty including all tax and material and labor. So we called them out for the system not working properly and the young kid Junior said that my outlet at the system melted because of not changing out the air filters soon enough (not true) and then proceeded to alter my contract and mark that it was only a 2 year warranty, which is completely illegal, as it is a binding contract. They did not fix the problem and I had to call them back out. They found the correct problem and Gene said he was going to charge me for the part, especially since I did not pay for anything earlier. Again, I referred him to my contract and he proceeded to angrily argue with us. He finally said, fine here just take it, I have had a long day, to long to argue with you. This is very upsetting!!! First of all, I did not create the contract. Sorry that you guys hired the person who did, but that is not my fault. The system was $5,000 and I did not appreciate being argued with over a binding contract that is not alterable! I am writing this today because we are selling our home and the home inspector is telling us that there needs to be a grommet on the gas line or a rigid gas line should be installed inside the furnace unit to promote safety! Really, another thing that they did not do correctly! What happened to the grommet the system came with? Why did they use a flexible gas line when that is no longer up to code? I really should be calling them to come back out to fix, but I am afraid of how I will be treated and don't want to argue over not having to pay for it because of my contract. I would seriously avoid this company if I were you! Ridiculous!!!

The city gave me a notice that I had a leak. I called Klaus and Sons and they sent out Fred. He immediately went work and fixed the problem. I was so afraid it would be a big costly job. It turned out to be an easy fix and not so expensive. Thank you Fred!

Bob L.

08/12/2017 12:00:00 SA

We interviewed 4 HVAC companies to get their input and quotes on a new a/c-furnace system. While there were hick-ups in the early communications with Klaus, the installation went great and we will definitely recommend them to friends. AND they were the best value of all four!

Ryan C.

1/15/2019

We called a lot of different places and no one answered or was willing to come out same day. Klaus and son's was recommended on the next door app so we gave them a call. The lady on the phone said Fred would be over in 30 mins. Fred was on time and very nice. He was able to get our leaky pipe fixed to our shower and water turned back on. He was very fair on the price and worked hard to get it fixed for us the same night. Very friendly and would highly recommended to anyone else looking for a honest plumber.

Arrived home one night to find a notice the gas co had shut off my gas due to a leak on my side of the meter. I live in an older home where the gas meter is at the street. Before they would turn my gas on I needed it fixed by a licensed professional. I talked to several companies, made three appointments for the next morning. The first two that came out were scary. First guy didn't even know that some gas meters are on the street and spent more time trying to sell me a new water heater. Both of them were talking 4-5 days to complete any work before even testing the system. Between appointments I talked to a neighbor who highly recommended Klaus & Sons. So I cancelled my third appointment and called them. They said they'd send someone out between 10-12.

Tyler showed up at 9:40, early, I like that. I told him the issue and he immediately laid out a 3 step plan for isolating where the leak might be and quoted a price for that. I figured, o.k. we need to do that no matter who does the repair, let's do it. He went to work, and immediately found the leak was in the main line from the meter to the house. That's a 60 foot plus run, under a side walk, across the lawn, under a double wide driveway to tie into the house. He provided me three options. One for a repair, which was risky due to the rusted aged galvanized pipe, and two options for a replacement. He even said he could clear his schedule for the rest of the day and start right away and may be done that day or the next. I went with a full replacement, and Tyler said he had to go pull permits and get help and would be back in half an hour. By 10:30 his crew had arrived and started working. Tyler showed up shortly thereafter and they dug a 2-3 foot trench, from the meter to the house, water blasted a line under the sidewalk and that double wide driveway, and had the new line laid and hooked up to go that afternoon. Unfortunately the city inspector had to sign off on it and wouldn't come until the next morning so he had to leave parts uncovered and wait til morning. The next day Tyler and the Inspector were there by 8 and it was signed off. Tyler filled in the rest of holes and was done that morning. By 2 that afternoon the gas company arrived and turned my gas back on.

This was done in the middle of the week on a Wednesday and Thursday. If I had gone with either of the other guys who came out first, I'd probably still be without gas (it's Saturday now). Tyler was great, laying out the options and letting you know exactly what's up. He even talked to my insurance guy who happened to call while he was cleaning up the last day to let him know what he found. I'm grateful to him and Klaus and Sons for the work and getting it done so quickly. Thanks!

Family member requested kitchen sink garbage disposal replacement. k&s wanted $1700, 3 times what it should cost. We found a reputable plumber to do the job at a 3rd of the price. Had them give me an estimate for a new AC unit bout 7 yrs ago quoted me 10 k more than every other bid. I recommend not contacting them unless money is no object. Cant vouch for their quality of service but their prices are gouging. It appears they Dont want to waste time on small jobs. Hence the outrageous estimate. Look elsewhere. Do better Klause

just replaced a 20+ yr old HVAC unit in a condo we own in RC. they were easy to deal with & very professional. prices were more than competetive. we checked with other companies in the area and very glad we went with Klaus & Sons. we had been given etimates of 3 days to do the job but they said 1 day and that's what it took. my husband was there for the day & was very impressed with the job they did.

Hey all you COOL CATS AND KITTENS.. If you want your AC up and running in a flash! I suggest you call Klaus & Sons ^^^.

We wanted to replace our toilet and called two companies prior to calling Klaus & Sons. One came out, we asked for a proposal and the company never returned our call. Second company gave estimate on the phone, but never called back. Called Klaus, they had a tech here in one hour. He gave us an estimate, set a date for the install. Called the morning of the install to tell us he was on his way. Arrived at the scheduled time, he and his helper were courteous, respectful of our home, the install and additional repairs took about an hour. They cleaned up everything, including removal of the old toilet. Excellent job. Nice to have a company do what they say they are going to do and arrive on time. We will definitely use again.

After smelling gas in our front yard we called the gas company who told us we had a leak and that they had to shut the gas off. The first business quoted us an outrageous amount and told us it would take 2-3 days to complete the job. Klaus & Sons got the job done within 4-5 hours. Very happy with the work. Will definitely use them again.

We recently moved into a new house and during a routine maintenance, discovered the existing AC compressor was running at about 40% capacity due to damage from a dog and some of the ducting and intake vent needed to be replaced. We found Klaus & Sons through the SCE website and a quick web search of their name found quite a few really positive reviews, so we decided to check them out.

They were very friendly on my initial call and were able to send someone out to give us a quote within a couple of days. They gave us two quotes: one for a 13.5 SEER unit, one for a 14 SEER and were great about explaining the differences. The quote was pretty much what I expected as far as pricing went, so we decided to go with them without getting quotes from other companies. They ordered the unit and a few days later called to let me know it arrived. I scheduled an appointment for two days from then.

Install day came and the two installers arrived at my house on time and ready to work. One worked on the compressor outside while the other focused on the ducting and intake in the attic crawl space. They were friendly and extremely professional. My husband had recently bought a Nest thermostat. The installers hadn't seen one in person before and installed it, no extra charge, just for the opportunity to learn about it.

I'm very happy with my experience and happy to recommend them. Although I hope to never need their services again, they will be at the top of my list if I do.

My husband and I were tired of the inefficiency of our AC. While the unit itself was operable, the system just wasn't working for us. We were constantly scrambling for ideas to make our home more comfortable but keep our energy costs reasonable. At around the same time we decided to replace our taxed water heater we decided to look into having our attic insulated. We had a couple of quotes on the attic insulation and I felt like the bids sounded gimicky trying to sell us services and products I didn't really feel that we needed. My husband thought of Klaus and Sons and made the call (at around 530pm no less) and they were out the next day. John listened to our energy concerns, got a feel for what we really needed, surveyed our attic, and talked with us about our options for a solid two hours. His knowledge and expertise was absolutely unmatched. Literally unmatched, not a single contractor explained or suggested the solutions that John laid out for us. We were so comfortable with the solutions that he suggested that we signed the contract immediately.

Klaus and Sons, removed our old duct work and replaced it with updated, insulated, properly- sized ducting, redesigned our system to properly circulate air throughout our house, thoroughly and properly sealed all of our walls and attic space, and insulated our attic. Oh, and they even installed a new water heater for us!

Each person who has worked in our house throughout the process has taken their time to do the job thoroughly and correctly. They absolutely pride themselves on a job well done and it shows. They have worked tirelessly, neatly, and efficiently, but I've been most impressed with how well they all work together. This is a company that operates like a well-oiled machine. Everyone communicates clearly, they have a common goal of satisfaction for a job done right. We've been hugely satisfied with the work that Klaus and Sons has done in our home. Thorough is the best word I can use to describe the manner in which this company works. They have worked above and beyond the scope we expected. We're not only pleased with the level of skill, professionalism, and expertise of Klaus and Sons but we're almost indescribably more comfortable. There is a measurable difference in the way that our AC system operates. Our house is cooler, more comfortable, the airflow is vastly improved, and the system is running smoother and more efficiently than ever before.

The only thing I regret about this process is the money and the time we wasted before realizing the magic that Klaus and Sons delivered.

***I would be remiss not to mention that mid-AC improvement I asked if they might be interested in removing our fireplace and opening up our house a bit. This was previously only a dream to me. The fireplace was nothing short of a monolith. It was a huge, solid rock structure. Not like the type of rock fireplaces you might see in a cabin, not a rock facade, these rocks were huge. Floor to ceiling with cantilevered concrete hearths on each side (yes, it was a two-sided beast) and about twelve feet across opening into the living room and kitchen. While interesting and unique, it really never suited the style of our home and was also non-functional as it had no damper/flue and only filled our home with smoke on the few occasions we opted to use it over the years. We'd discussed cosmetic options previously and even consulted with concrete/masonry contractors to see if they might be able to improve, if not remove, it. It seemed insurmountable to us for so long. When I asked John whether it was something they might be willing to tackle he responded that while it would be a job that it was nothing they couldn't handle. They handled it! The difference is amazing; we now have better airflow, more open, updated, cleaner, and just a completely improved state of our home.

Hands down - the best Heating/AC company out there. We have used them for years for our annual tune-up, but when it came to the installation of a new AC/Furnace system, we knew it would be an expensive and daunting task. We did ask for several different company quotes, but when it came right down to it, Klaus & Sons came out on top. In this case, getting what you paid for clearly does not apply. Their quote beat every other 4.5 and above star company out there, and it was the most comprehensive and accurate for our home. But, what really amazed me, was the crew that completed the installation. There were quite a few that came in & they went straight to their assigned tasks. They completed everything in 2 days, and at the end of each day, they were so thorough in their clean-up, you would have never known they were here - they even wiped down the walls from dirt & grime from the attic. The main reason for us - as to why they are the top of the best out there - is how respectful each and every technician was to us, our home, and even our pets. Quality service is what we got and at the best price. If you chose them, you don't ever have to second guess your decision.

We had a foundation leak and this company came out right away, was completely professional, left the property picked up and took care of all of our concerns, including with the estimate; sending someone to fix the tile, drywall, and stucco that had to be disturbed for the fix. I highly recommend this company and will be using them again.

First time using this company. I made my appointment a week in advance and was told at that time I was the first one to make an appointment. I had an appointment for the 8:00am-10:00am time slot. After not seeing or hearing from anyone by 10:00, I called in at 10:10 to ask the status. After some fumbling around to find me in their system, I was told the service tech got hung up and was running behind. I was told by the scheduler that she would try to have him come over asap...what?? I had to ask her that since I had the early appointment that I should be given priority consideration over others with a later appointment...she agreed but still couldn't give me a time other than, well, between 10:00-12:00. Depending on how this appointment went, I was going to use them for heating and air...well, not any more. I called another place and got an appointment same day. This place had very poor customer service .

Professional responsive & reliable, they are the go to for my plumbing needs.

These guys are a class act. Not only have they helped me fix any number of plumbing issues around the house but I also wouldn't be anywhere near as cool as I am thanks to to their air service. I'm a drywall contractor too and have done allot of business with these guys over the years and know them to always look out for their customers first. It's a family business run like it will be passed through many more generations. Everyone there is so competent and if you meet Klaus you'll get an idea how this place stayed in business for 40 years. You can't go anywhere without seeing their trucks! Old school business values, family business and top notch craftsmanship means you can send these folks to your moms house without worrying about them trying to get rich on one job. Like I said in the beginning, Klaus and Sons, Danny, Jesse , grandson Chris and all their other top notch journeyman are class acts!

Used Klaus 14 years ago for a big job but haven't needed plumbing since. Lucky me. Unfortunately today I had a badly clogged toilet. Nothing I tried unstuffed it. Called and Tyler arrived within 20' because I told Tiffany it's the bathroom my heart weakened husband needs to use. Tyler unclogged the toilet but checked the bowl and noticed one of the bolts was snapped off and would require a reseating procedure which raises the cost. He gave us a discount on the combined costs and added a senior discount. Still an expensive day but the job was done quickly, cleanly and effectively. Tyler was so pleasant and I really thank Tiffany who even after 14 years still had us in their computer. Going local is always a good thing. Thanks Klaus. Hope we don't need you again too soon but it's good to know you're there.

This is a great company to do business with I had a plumbing issue and I was able to have some one come out right away to give me a asement and quote on my situation it was great to have that done at no charge where every other place I checked with wanted a fee just to take a look. After hearing what had to be done the price was very reasonable and the work was able to be done very quickly for me my workers name was Fred he was great very professional and wonderful personality he did a fantastic job and if I ever have any issues again will use this company

About 3-4 weeks ago, my home's AC unit decided it wasn't going to blow any cool air and of course, it came at an opportune moment when the weather decided to hit 90º. In brief, I went to Yelp and looked up companies handling HVAC services. I initially wanted to go with one other company but decided to look up Klaus & Sons - SO GLAD I DID!!!! I couldn't be more happier and 200% satisfied with the services of Klaus & Sons. My father (William) spoke with John Howe and Gene, the technician and both went above/beyond the level of customer service. This company has been in business for 40+ years - not only are owners and staff experts in the field of HVAC services, they understand connecting with their clients/customers. For me, that's a WIN in my book. You get what you pay for - 100% customer satisfaction if not more.

Our water heater started leaking at the tail end of a holiday weekend, and necessitated a full replacement. I gave Klaus and Sons a phone call on a Sunday afternoon and left a message regarding a replacement quote. Within 10 minutes, Bryan @ Klaus and Sons called back and asked a few questions, asked if I needed same day emergency service (a handy option if you really need it, but I declined), and set me up for a replacement swap-out on Monday morning.

Bryan showed up exactly on time, was very polite, kind enough to answer all of my questions and more importantly, got the work done right and quickly. All things considered, we were only without hot water for about 24 hours thanks to Klaus and Sons. Very professional shop and a great plumber; if I need future services, I will definitely be giving them a call first.

Needed quick service to repair a leak in the bathroom sink. Michael was professional and knowledgeable. Fixed the leak and was able to offer tips and tricks to avoid future plumbing issues. Was able to give me a ballpark estimate on another repair that was possibly needed and even showed me the tools I would need if I was interested in doing the job myself. I appreciated his honesty and that he wasn't trying to push services. I would definitely call them again for future repairs and emergency plumbing services.

My kitchen drain was blocked and backed up. I called Klaus Plumbing and was able, with the help of the receptionist Monica to obtain an appointment for the same day! She was professional and kind, understanding that the plumbing business I had secured an an appointment with the previous day, called 24hrs later stating that they no LONGER serviced the area.
Michael was prompt, polite, and gave me a quote prior to service. Work was completed within the hour.
Thank you.

I had Klaus & sons work my heating problem yesterday. My heater would start but then shut off in minutes before reaching the desired temperature. And, my thermostat led light stayed red even though the heater was not on. Additionally minutes after the heater turned off the thermostat display would go blank, and then later the thermostat display would go back on.

Dave resolved the issue. He performed many diagnostics and discovered that the high distribution voltage to the blower was faulty and he replaced it. He also replaced our filter which was almost due for the 6 month change over. Additionally, he recommended that I replace the flu vent cap for proper air flow. The old flu vent had fallen off the roof during the winds and was most likely damaged and blocking air flow. So I removed the old flu vent cap while Dave was here. And, the heater was working fine again. Then after he left I purchased a new b vent cap from lowes. And, I installed it that same evening. And it continues to work after I installed the new flu cap. The price for Klaus and sons maintenance was very reasonable. It was less than $300.

Dave also serviced our A/c unit. He did a a/c tune up. And, he also performed a heater tune up. He suggested that in the near future we should get a major service for both heating and a/c units since no major work has been performed on it. My hvac was purchased April 2008.

I am so impressed with the professional service provided by Dave. In a few months when I decide to have major service performed, I will request Dave.

Klaus and Son's has been the first and only call that I make for all my plumbing needs. Have been a satisfied customer for many years both for commercial and residential jobs. The guys are great, professional and always do excellent work, on time and reasonable. Their office staff is always helpful and work to take care of emergency situations fast. Highly recommend them.

The job was over priced by $200!!- however - I just wanted the bathroom vanity drain pipe replaced and call it a day. I didn't want to call around. My neighbor was using them at the same time- that's how I found them! Yup! He did a great job. He was done in an hour. Cleaned up the mess. I'm happy we can now move on- just a bitter feeling of being over charged! It's done!

Our 30 year old Lennox ac finally quit and we needed to replace to a more efficient (non R-22) system. Dan came out and courteously explained what needed to be done, and gave us 3 options. Based on other quotes, their price was competitive. This included permit and HERS testing, not presented as add-ons.. Despite being in a severe hot spell, they were able to come out in a very reasonable timeframe and installed over 2 days, We were impressed with the professionalism and care of installation- covering wood floors to avoid scratches and thorough clean up when done. Kevin, Junior and others were polite and took time to explain what they were doing and discuss some options during installation. A senior technician came out to check and fine-tune the system after installation. All in all very pleased.

Have used them for multiple times and all went smoothly. They have replaced the condenser in the past few year and fixed the outside compressor just recently. Technician is professional and cut to the chase no bs no lies. They are honest and dependable.

I used Klaus and Sons for a plumbing issue last year. I was happy with their service, so I thought I would try them again. Today, I had them replace a toilet and shower handles, and I was very pleased with the results. Sal Tretolla was professional, quick and thorough. I am so glad I called them again!

Our pressure regulator needed replacing along with the main shutoff. We set an appointment for the next morning. The technician, Fred, was right on time and very friendly. He suggested a couple of changes and I agreed to add another shutoff separate for the sprinklers. He got to work and finished the job very quickly. Extremely pleased with the great service.

I'm leaving this review on behalf of my dad who is a very happy camper with this company and with Gene (:

After having my condo remodeled I soon found out that neither the AC nor the heating system would activate. The contractor whose electrician replaced the thermostat did not return my messages. My dad finally gave up on them and called Klaus and Sons.

Klaus and Sons have done work for me in three locations in the past. I called them and they sent out Gene who took less than 10 minutes to verify that the thermostat was improperly wired and had consequently blown a fuse when I tired to run the heating. He proceeded to the attic and replaced said fuse.

Gene was efficient, tidy in his work, and wore shoe covering to protect the new carpeting. He even gave the AC compressor/condenser the once-over before departing. The charge for his visit was remarkably low. ~ J.D. Hedley

Our heater broke over the weekend (it's was 50 degrees in our house so we were desperate to get someone there ASAP) Gene arrived within an hour and he was very quick and friendly. We needed a new filter and some other work done but after 45 min he was gone and our heater was working. It was a bit pricy but use the 10% off yelp coupon! Thanks Gene and Klaus & Sons for the help!

My A/C died at the end of last summer and I was in the market for a new unit. Luckily, since fall was around the corner, I did not need to rush into a quick decision. This gave me the opportunity to meet with several companies.

I chose Klaus and Sons because 1.) Dan (owner) was professional and knowledgeable 2.) he was very patient in answering my questions 3.) he did not put any pressure on me to purchase my system through his company. Plus they were a recommended company listed on the SCE website.

My new A/C and furnace unit were installed in November 2012. I really haven't had an opportunity to put the system to the test until recently.

I would have given them 5 stars if the installers had arrived on time instead of 2 hours after the scheduled installation time. About an hour after the scheduled installation time, I had to call and verify that I was on their schedule for the day. This was an all day installation.

Everyone that I spoke with at Klaus and Sons were professional and friendly. During my initial meeting with Dan, he asked questions about my wants and needs before making any recommendations. Chris came next to measure for BTU usage. This ensures that the proper size equipment is installed for maximum comfort. The installers were neat and clean. My inspection with the city went smoothly.

I would definitely recommend Dan and his team at Klaus and Sons.

The first number I call for any plumbing or HVAC services is Klaus and Sons. They have taken care of our needs in Upland for many years, and today was no exception. Gene arrived at the house to address some issues with our noisy heater and will be back tomorrow, along with some installers, to replace a necessary part and to update our leaky ducts in the attic. I have found their service impeccable and Gene very knowledgeable and helpful.

I came home from work and noticed my ceiling was leaking water. I called Klaus & Sons. Jessie, Sal & Chris responded in 15 minutes. They assessed the problem and went to work immediately. They saved me a huge headache. I highly recommend Klaus & Sons. They're easy to work with and very cool dudes. Great job!

Thank You to Wes who came out today and worked so hard to solve my grohe fixture issue. A great product but just a little lacking in the instructions made his job much harder than it had to be. Thank You for not giving up and fixing it and saving me some money in the process.

At 6:30 PM the plumbing backed up and the water started flowing out of the toilets and shower drains. I called Klaus & Sons after-hours on a Friday. Within a few minutes I was talking to the on-call plumber, Sal. He arrived within 45 minutes, quickly assessed the situation and made two recommendations from which I could choose. The plumber was friendly and worked quickly. Within an hour the problem was solved and the toilets were once again flushing. All this was done cleanly and efficiently. We will definitely use Klaus & Sons Plumbing again should the need arise.

Worked on my ancient wall heater and got it working again. They also made recommendations about safety and possibilities for replacing the unit in the future if I wanted to update the system.

Klaus & Sons has always delivered for us. Whenever I call with an issue they respond as soon as possible and do the job right. For this call we had a leak in the slab that required the area to be jack hammered and reconstructed. Sal was happy to adjust his plan and completed the job that day with a smile. I could not be happier with the service I recieve from Sal and Klaus & Sons.

Super professional! They were prompt when inspecting my AC unit, as well in providing a reasonable quote. I did not get my AC unit serviced after all, since it started to function again. I will keep Klaus and Sons in mind should my AC unit craps out again.
