Best Heating & Air Conditioning/HVAC in United States

Needed a new A/C unit installed because dog had been urinating on the previous outdoor system. Spoke with Jason who was able to get me a reasonable quote for a new unit installed. They were very patient and listened to my concerns as I had just been ripped off by a different competing place who had been out three times including charging us for coolant when it was spot on obvious there was corrosion and a leak (I do not recommend Simply The Best).

Jason provided the quote and the install was done within a few days which is excellent response time considering I was in a jam and summer is here. Installers were very professional and even had the job done under the quoted time frame and did preventative maintenance on the other existing unit. Recommended. Straight forward, friendly and professional and don't play games with you like some of the other guys. We need integrity living in Arizona with the heat and I can say based on my experience, Northern Air provides exactly that! Thanks again and will use in the future for all cooling and heating needs!

Robert did an awesome job for a reasonable price. Good attitude, worked super hard, got it done in a timely fashion. Will definitely be using him again for anything we need hvac related. Recommend him highly. He replaced our air handler and condenser and relocated it all in one day.

Very helpful and honest company. They were able to complete the requested work very quickly. I would definitely use them again.

My HVAC broke down end of August, Heat warning in effect and literally 2 hours after I called McMillin Air their technician Lalo had my A/C up and running again!!! I can't begin to tell you how impressed and grateful I am! They will have all of my future business. A million thanks is not enough.

Semi-annual service was performed on our AC/Heating unit. As always with Hobaica, the technician was very professional and courteous. The unit is ten years old and still operating very well, largely thanks to Hobaica's maintenance and small upgrades that reduce stress on the compressor.

My parents purchased a home and needed a new unit and new ductwork. LRG did a fantastic job. The pricing was fair and the work was completed fairly quickly. Very professional. LRG is the way to go!

Comfort Experts is everything you want out a company. Ryan showed up ahead of schedule after one of the quickest replies I've had in years. Not only was he courteous,  professional,  quick to diagnose the problem but his pricing was very reasonable. I highly recommend CE and if I need ac or heating help, I will use them from now on.

Jake is an outstanding guy! On time, friendly, good service and attention to detail!
Thank you

I've never had the need to write a review for any business before but i just couldn't be more glad that it's for K&K. My mother is 83 years old and had her heating unit go out on her during the coldest time of year. I called a few other company's to please check the unit, when they found out it was an older unit they flat refused to even come out. I came across K&K and figured i'd try one more. I spoke with Danny and he was more than glad to come out, even though it was raining that day, he offered to come out same day. He came and checked out the unit and did his best to try and get heat to the house for my mother, who by the way suffers from crippling arthritis, but was unable to due to units condition. He wrote out an estimate for a replacement unit and asked me to call if we needed his service again. After he left my mother told me that she had a great feeling about this man, as did I. He must have felt something because he called later that night to check on her and again stated that if he could help in any way to please call at any time, day or night. After contacting the insurance company they asked for better wording as to why unit needed replaced and Danny was able to help us out thru the whole insurance process, and also worked us into his schedule to make sure my mother got heat as soon as possible. Danny is an awesome man, And K&K is not just a business, they are now FAMILY...  Thank You So Much

Moving to the Valley leaves you a bit nervous when looking for repairman. Fortunately we found Dalen at Reliance. They came out and gave us a fast estimate and ultimately installed a new AC unit without forcing us to get more than we needed.

It looks like they have a great business going and I would recommend him to a friend and use them again.

Last week, I called AccuTemp Refrigeration based on reviews from Yelp.  We moved into a new home and needed to see if the AC was working well and up to snuff.  We set up a schedule easily for two days down the road.  Ken was our technician.  He came right on time.  He checked everything in the attic and noticed a some potential for the clogging of the overflow system.  He made a $20 adjustment to ensure good drainage.  Next he looked at the unit (17 years old) and indicated that it was still in good working order.  We also had some rattling noise that we could hear, so we were expecting a condenser problem or some other problem in the ceiling.  It turned out that the vents rattled when set a just a particular angle.  He adjusted them, no more rattling.  Total cost...$80 for the maintenance check and minor drainage adjustment.

During the whole process, Ken would provide instruction on what he was doing and the potential problems and solutions.  He was very informative and honest.  I would recommend Ken and AccuTemp to anyone.  They were very good.  My mother is going to call them soon to service her AC.

This company is by far the best I've dealt with regarding my A/C system. I wished I would of contacted them first which would of saved me a lot of money. I had another company redo my duct work because of poor air flow out my vents. After the other company completed the work I still had poor air flow. I paid the other company 3k to do it and they never came back to re-evaluate the system. Well during the summer my A/C unit stopped working. I called Day and Night and they came out right away. They said my unit over heated and shut itself off. The reason why it over heated is because my duct work and return line was under sized for my A/C which was supposed to be fixed by the other company I paid. Peter from Day and Night came out and evaluated every aspect of my system. He took good notes and told me what needed to be done. It sucks that I had to pay another 3k to get it done but they did it right like it was supposed to be. The two technicians that came out, Kevin and Johnny did an amazing job!! They were very polite, detailed oriented, cleaned up any mess/dust that was made, very knowledgeable and experienced with the work they were doing. I am so happy with this company and I wish I could give them more than 5 stars because they deserve it. I highly recommend this company. The difference is truly Day and Night with this company!!!

Both of our AC units were on their last leg, house is about 20yrs old. I got quotes from 5 different companies, many of which were much larger, lots of the larger ones sent out dedicated sales people which was kind of a red flag for me that they need to charge higher prices for all of their extra employees. I'm really glad that I found DeModica Air, Jon Jon came out the day after I called him, explained all of my options, including patching my existing units which he said he could get them to last probably another 3 years. But he recommended replacement and we are glad we went with his recommendation. He had both units replaced, along with the air handlers in just 2 days. I highly recommend giving them a shot, at least invite them to give you a quote.

We called got a call back right away. Had a technician Jeff come out the same day. Had our Air conditioner installed 2 days later. Very Quick respond. They did a very good job. Thanks for your service Garrett

Last month our a/c stopped working. We filed a claim with our home warranty company on a Saturday and I was so worried that we were going to be without a/c for several days. Being August, 8 months pregnant, and also having a 1 year old I was very concerned! My husband left a message on Sunday, and someone contacted him back letting him know they would be out early Monday. The communication was great and the tech who came had the part we needed on hand and fixed it right away. I was so thankful! Great customer service and no further problems, couldn't ask for better!

Kevin really hooked us up. I work in the hvac industry so I know a good price, what a professional does, and what should be included. He hit all the marks.

Keep in mind as I am writing this (Summer 2021), there are NATION WIDE equipment shortages, for every brand, every where. At least for now you can expect delays getting equipment. Knowing this, we ordered ours ahead of time. Called a few companies, some didn't even bother sending a proposal (why did you waste your time coming here at all..?)

We have already recommended this company to 3 of our friends.

They were very friendly and personable. And to top it off they were inexpensive, thorough and fast! I had a great experience and will definitely be using them again. Hopefully not for another clogged kitchen sink...

I had to call this company because we purchased a home with a new A/C & heating system installed in the home 3 years prior with the former owner.  When we had it maintenanced from a different company, they had pointed out some major errors with the install.  So we had to call Precision out to check out the installation job that they had done 3 years prior.  From the people in the office to the installation manager (Shaun) it was nothing short of awesome service.  Shaun confirmed the prior installation issues and repaired them on the spot with no questions asked.  Thanks so much.

I have a fairly new home, built less than 2 years ago, and my tankless water heater went out a few weeks ago. The company charged me for a part I didn't need that was still under warranty. It took two weeks for them to finally fix it and all it needed was an electronic master reset.

I reached out to ask about why they charged me for a part I didn't need and they said due to all the time they spent here and on the phone with tech support.

Here's the issue I hope you correct going forward so it doesn't impact future customers:

1) Your technician didn't spend more than 5 minutes here the first time. He didn't troubleshoot anything. I told him the code and what I looked up online that led me to calling you. He said yup that's it. Then he left.

2) Had he troubleshot the issue it could've been resolved that day and we wouldn't have been without hot water for two weeks. Also, this would've prevented the ordering of a part that was unnecessary.

3) The second technician said he's not a plumber, rather he's an HVAC guy. I think having the properly trained technician would have sped up the job, reducing time wasted on troubleshooting a master reset.

I am giving 2 stars instead of 1 because  I am thankful the last technician that came out was honest and was able to resolve it and get the water heater working.

Our heater went out so we called Canyon State. We got a quick fix but unit was 13 years old and needed more work done to function correctly. Michael came out next day to explain fixing or replacing. We opted to replace since unit was so old and not that efficient any longer. Two days later Manny and Steven came and installed the new unit. Very professional men and it was done in no time. BOY what a difference the new unit makes. Also want to state that lady that took the original call was very caring and listened to our problem then referred us to the proper person for a solution. All aspects of our transaction with Canyon State were  5 star
