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.

They arrived quick and repaired the Heat Pump /AC unit in timely manner still working well

Have used Hobaica Services several times now. Had a major renovation project that required some outside the box solutions and they came through. Great communication from Kyle and Mike and equally great work by Ethan and Angel. These guys charge fair rates, do great work and can be trusted. Highly recommend them.

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!

Had received quotes to replace my A/C system in my home that was 20 years old. I contacted Comfort Experts and Ryan came out to the house to discuss and give me a quote on my system.  I was totally impressed by Ryan and what he was going to install that I hired him on a Friday and the install was set up for the following Tuesday at 7 am. That morning his team arrived on time and started to work at once. The guys were awesome..friendly and professional.  They explained everthing that they were doing and answered all my questions. They were neat and cleaned up above and beyond and their work was outstanding. I highly recommend this local company for their professional, friendly, and quality of work .

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

Referred by a friend, I called and Pedro answered very quickly.  Very polite, helpful  and quick. My unit was old and required special parts. When the unit was returned to working order but not quite how it was before due to the parts I ordered they gave me a full refund. I will definitely  be calling again when I am able to replace my entire Unit.

Wow. This company is fantastic.
I had a new furnace and AC unit installed today. The employees are unbelievably neat, clean and professional. They showed up on time and completed the job in the timeframe given.
They even raked all the gravel around my home where they had hauled the units in on the dolly. The attention to detail is amazing!
I would never use anyone else again.
This is also a local & family owned business.

Our AC went out, and we had to call out a different company because it was after hours on a Thursday night and we couldn't get a hold of AccuTemp. The other company misdiagnosed the issue, quoted us over $1200, and said it would be 4-5 days to fix.

We had AccuTemp out for a 2nd opinion the next day. They were immediately suspicious of the proposed issue, as it's (apparently) not a common problem for a not-very-old AC unit. They were correct. It ended up being a confluence 2 simple issues - a plugged drain pipe and a bad capacitor. It was fixed in 45 minutes for $200. It was fantastic. The tech was very knowledgeable, and honestly our relief is difficult to even put into words. It saved us $1000 and days paying for a hotel.

The only caveat I would put (and the reason this is 4 stars not 5); I wish Accutemp's after-hours service were better. They were the first people we called, but we left a voicemail which wasn't ever returned. That forced us to call a different company and go down a bad road.

Otherwise, this is def. a company you can trust to be honest and treat you well. They installed our unit years ago, have dealt with a couple simple issues since, and been great.

I had Day & Night do an emergency repair to a water line from the water meter to my home. The staff I spoke with were helpful and pleasant. The technician (Cameron) was friendly, knowledgeable and efficient. They were the only company I called on a Saturday afternoon that was willing to come out and fix the broken main water line within 4 hours. They actually came 2 hours early. I would give them 5 stars for how I was treated and the work done.

I am giving 4 stars due to many of the other comments related to price. I thought $746 was high for 2 hours of labor and minimal material cost, but it was a same day repair request on the weekend. I think most of what homeowners get charged is generally on the high side nowadays. I understand various factors go into pricing and likely many other companies would have charged similarly. I would still use Day & Night again due to their quick and professional service and friendly staff.

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.

A less than four year old condenser unit would not start up. Called Stay Cool and had an appointment window for 2-5 PM. At four pm i called to confirm and they said yes, but someone else was in front of me. 5:30 PM rolled around and no Stay Cool. No call, no nothing. Unreliable, unprofessional. Buyer beware.

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 did a fantastic job installing a complete new air-conditioning system for me in the middle of summer in fact on the Fourth of July holiday  2015.
I was fortunate enough to have a good friend that I've been swimming with for seven years and her husband is pretty good at fixing things but he took a look at my air conditioning and said you need my guy to take a look at this and see what needs to be done. He sent over Kevin who took a quick look and said that my compressor was broken. He said other than that and the air-conditioner was in good shape and was actually only 10 years old which apparently is a baby in Arizona.
I asked Kevin how much it would cost to replace the compressor and give my system  a good service. Kevin said it would be $2000. It would be more expensive because I had been running the AC thinking if I ran it, somehow it might magically repair itself. Then I asked Kevin how much it would be  to get a fuel-efficient up-to-date modern new air-conditioner.
Kevin informed me that he could put in a complete new system that would run economically and be eco-friendly for around 4 1/2 thousand dollars. That price would include all his labor.
No-brainer of course I would go for a complete new system it seemed incredibly reasonable.
And also informed me that by 2020 all systems would have to be compliant and my system used Freon and new systems in 2020 would no longer be using Freon although if they were an old system and you had a stockpile of Freon you could use it.
I care a lot about the environment and in all cases I prefer to use environmentally sound products.
Kevin had to special order my new AC unit and in the meantime I purchased a freestanding unit and spent the next few days in my bedroom trying to stay cool.
Once my new unit arrived Kevin worked extremely hard to install the new system starting first thing in the morning and working outside and tremendous heat until it was dark.
Took Kevin to full days to install the new system but once it was up and running and it was an incredibly smooth and quiet system and I was amazed at how efficient it was.
I have always been economical and using my air conditioning since I live alone in a house that is two stories.
I had my way I would have individual unit air conditioning her room as I think central air-conditioning is such a waste for a single person living alone. Sadly the homeowners association will not allow us to have individual units as they say it is unattractive to have units showing in the windows it's perfectly ridiculous.
So I have to cool my entire house which to me seems great waste of resources in these days when we are wasting precious energy and polluting our environment.
However my new air-conditioning system is so efficient and powerful that within an hour of turning it on my house seems very cool where is the older system would take 4 to 5 hours to cool down the house.
Send noticed that my electricity bills are much lower now with this efficient new system
I would highly recommend Kevin to anyone who is looking for an honest hard-working and very pleasant man who really knows what he is talking about as far as all aspects of air conditioning are concerned.
Kevin  is hard-working and diligent and will give you an extremely valuable and efficient service.
When I turned on my air conditioning for the first time this year it came on and was very smooth and cool. I did have one blimp when somehow the air handler got flipped off and I had not realized it but Kevin came over at the drop of a hat and switch the switch back on and everything is running smoothly  again.

I used this company for a plumbing issue with my kitchen sink. I actually found them here on Yelp and decided to give them a try. I was so happy with my service! I called in the morning, received a response within 30 minutes, and was able to get same day service within a few hours. Excellent service by a friendly and knowledgable worker! I would definitely use this company again and recommend to anyone who needs it. Being reasonably priced was a bonus :-)

Just had a routine service with Matt. Matt was very professional. The only downside is that the service does not really service anything. I end up getting a couple recommendations for repairs that I may or may not need and they are extraordinarily expensive.
I thanked Matt for his recommendations but passed on the additional service recommendations. My review is 4 stars for Matt and 2 stars for PA.

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.

Called Canyon State to service and maintain our air-conditioning heating system service technician Pablo did a very thorough job checking our furnace and air conditioning very satisfied with the service would highly recommend them They were very prompt arriving on time
