Best Tankless Water Heater Repa… in Oakland CA

My old water tank heater was almost 20 years old and is no longer manufactured. I wanted it replaced with energy efficient kind (amongst other updated features) before issues arose. I considered a tankless heater, but this would entail much reconfigurations and higher costs.
I did my own research on a few tank heaters that are not sold in big box stores, and it boiled down to two competing popular (somewhat high-end) brands. After interviewing three licensed plumbers with good reviews I chose Asire Plumbing due to the owner patiently discussed the two brands in detail, since I couldn't decide which to pick. The KSP website also has a few photos of past work, and the office staff were professional and responsive. Added to all this was the reasonable price and extensive knowledge of the different brands.
I also had good experience with the installer, Vladimir and his work partner: they were honest, careful, efficient, cleaned up the work area and professional. Kenneth Asire Plumbing is true to what they said will  deliver. I have no qualms about using them again. Thank you, Kenner Asire and Staff!

Used these guys to upgrade the sewer lateral in a recently purchased house. Their bid was the lowest. The house is old and on a hill but they handled everything no problems. Service was excellent. Highly recommend.

I called at 9AM and they got here at noon!  They were not cheap but again - what Plumber is!  

Technician was professional and cleaned up the area.

I've been wanting to install a tankless water heater for some time now.  I wasn't expecting my water heater to fail on me as soon as it did, but things happen.  I went out and bought a tankless and then started looking for companies to do the install as that's the only way to preserve the warenty.   I had three different companies in mind, but Innovative Radiant Heating was the company I went with more for the fact that they're local and I like to support local businesses.  We talked, got a quote, and they showed up on time to do the work.  They did a great job and were pleasant to talk to.  Everything works great, and we're stoked.  I would highly recommend this company to anyone looking for this type of installation.

Gil was reliable and helper fixed the leak at home. He was cost effective and highly reliable.

Another happy customer here.  Martin and his assistant put in a gas line for me on my deck for a firepit.  When I left a message on their website I immediately got a call back, even though it was late Friday evening.  On the day of my appointment they showed up in a very well equipped company van and were very professional and polite.  They didn't even mind when they had to pull up the deck boards to get access to the pipes.  They did a great job installing the gas line and were very meticulous about cleaning up and putting everything back in place.  I feel their prices are good as well.

Elite did a great job fixing our water heater. Professional job and completed in time. Would recommend to anyone!

Once again a solid performance by Savior! In and out on less than an hour. Send them a pic of the problem and they arrive with replacement. Staff is ALWAYS friendly and flexible throughout the process. Highly recommend them on your next epic plumbing issue!!

I've known Rey for many years.  He tiled my bathroom and installed a new toilet.  I am still getting compliments on that job.
Recently, I asked him to replace the sewer pipe in my basement - big job, but he and his crew did it quickly and cleanly with no real disruption to me.  He also gave me hot and cold water for my washing machine, which I had never had, and hadn't thought of - all for the same price. Plus, he rerouted the gas line for my stove!
Rey  Lacayo and Amy Colt are great people and have a wonderful family.  He has a SF number and doesn't mind coming to SF.

My furnace stopped working and I requested service to determine the issue. They responded quickly to schedule appt. My furnace was 30yrs old so I decided to replace it vs fix it.  The quote was fair.  All representatives with Jazz were friendly/courteous.  During the service visit and subsequent installation, the guys were informative, knowledgeable.   Re: the install itself, the setup was clean, nicely done.

Have had issues with a tub for weeks and others were unable to fix the problem, but we were able to get it fixed same day.  Quick and efficient!!

Called in to have piping under our house looked as it was making rattling noises.  They asked for my full name, seemed reluctant to take this job, then said their system was down.  I asked for a call back, which I never received.  I don't recommend using this shop.

We had some work done replacing the ductwork in our home by another contractor, who left town without actually doing the balancing of our heating system that he had claimed to do.  We called A.T. Weber.  Josh showed up on time, spent quite a bit of time checking out the entire system, did some tweaks to both the furnace and the dampers, and talkled to me about options for upgrading the system.  He was quite frank in saying he didn't know if a new furnace would be able to overcome the effects of the single-pane windows in our 1908 house.

The next morning, I was delighted to find out that the tweaks he made had rebalanced the home in just the way I was hoping would be possible.  At this point, I see no need for additional investment in hardware.  A caring, knowledgeable technician is worth his weight in gold!

wow. put in yelp request late fri night, they called 7:50am Saturday, Will was here by 8:25 Saturday morning, drain was all fixed by 9:30am.  Will was super nice and friendly, whole thing could not have possibly been easier or more convenient.  yes, it was just a simple problem but they crushed it.

What a breath of fresh air after mo this of plumbing troubles! Can't recommend this place highly enough. Quick response, thoughtful advice, clear communication!

This is the second time we've worked with Carlos and it's always a great experience.  He's responsive, always tries to fit you in, thorough and all around a great person.  The first time we worked together, he was able to quickly help us with our plumbing under the kitchen sink - fixing what past plumbers had done in error.  This time, he rescued an earring from our bathroom sink in record time.   As long as he's in business, I'll never use another plumbing company.

Our water heater started leaking and I reached out to a couple of companies on yelp. Infinity was the first to respond. They sent out Carlos to provide us with a quote. The price was lower than the other two companies and they had everything they needed on their truck to get to job done.
They were done within a couple of hours and we had hot water with in an hour of them finishing the work. I'm so happy with their service from start to finish,  the office staff were professional and the technician Carlos was polite and explained to us how to maintain our water heater to prolong the life of the unit. I'll definitely be calling these guys again if we need any plumbing work.
Thank You guys.

fantastic guy, very honest (he could have told us there was an elephant in our pipes and we would have paid him to remove it) and super fast. We had a clog that we couldn't handle with our non-electric snake and he came over within an hour and a half of us calling and dealt with it quickly and was out. Oh and he's very reasonable!

Oliver came out and took care of the problem quickly and cleanly. I don't want to need their service again, but if I do, I'm going with Oliver and Discount Plumbing.

Purchased an old home in Oakland with very old HVAC. Worked on inspection and died after move-in. These guys came out quick, on-time, diagnosed the problem and fixed it within 2 days (needed to get parts). I had them run a full system check as well. Friendly, knowledgeable and reliable. Will be using Supreme for our HVAC replacement this winter as the old systems are on their last legs. Thanks guys, keep up the great work!
