Best Heating & Air Conditioning/HVAC in Phoenix, AZ

Had a great experience with Northern air. They came and worked with me on a project converting a garage in to a work space. Jason was super communicative. Gave me good info on the best path to take. Cody came out to so the install, he was also great, ran in to some unexpected challenges but handled it like a pro. Jason followed up after the job was complete to remind me that if I have any issues to reach out and they would take good care of the work and any issues that arose. Perfect customer service and you can see that as it's reflected in the ratings! Big respect for running your biz the way you do! 10/10

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 have been above and beyond in the installation and servicing of my equipment. They are kind, prompt and unbeatable when it comes to customer service. I highly recommend this company.

Our first experience was not great, but they're offering to make it right. I appreciate Chase's calls to help us.

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!

We hired comfort experts a year ago for a brand new air conditioning and heating system. I got free quotes from multiple companies in the valley and comfort experts by far had the best unit/brand available for the best price. On top of that, the gentleman who provided me with the quote was friendly, knowledgeable and explained the entire process to me in depth. The technicians the day of install were efficient, super focused and friendly as well. It was a great experience overall. Thank you, comfort experts!

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

K&K answered our Yelp inquiry within 20-mins, and scheduled an appointment the same day.

Tech diagnosed the problem quickly, and was able to fix the issue from parts he carried on his truck.

Quick service, easy to work with and fair price, so would recommend K&K and will use them again

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.

I can't praise this company enough. Our A/C had broke on Thursday afternoon on an early August day when the temps were around 110. When I called Accu Temp on Friday morning, they first estimated someone would be out between 2 and 4 hours, but then called back that they rearranged their schedule and had someone out in 30 minutes.

The person who came out, Ken, was thorough, knowledgeable, and most of all, conscientious. After spending all day up-and-down on the roof in the sweltering heat, without taking a lunch, and after having put his ladder and tools away, he wasn't happy with the differential between the intake and out-flow temperatures (he expected 20 degrees and it was 16 degrees), so he got the ladder and tools out again to add  1/2 pound more of refrigerant, and the differential was now the expected 20 degrees. And this was on a Friday afternoon to boot!!!

Trust is hard to come by now-a-days, and not only will we stay with this company for on-going maintenance and inspections, but will whole-heartedly recommend this company to friends and co-workers.

They are a great company!  Really easy to work with with very reasonable pricing.  
When we renovated my home we used them to provide and install a new split system unit and run new ductwork which they did without any issues or any hidden costs.  Then a few years later the other unit on our home (which was 20+ years old) stopped working, they came and installed a new unit that was perfect for about a year and half when it just wasn't cooling as well as it previously did.  After a short phone call they got a tech scheduled still under warranty to get the unit running perfectly again.

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.

So I purchased a mini split to go in my garage.  I called Stay Cool the owner Garrett was prompt in calling me back and gave me a great price to install it.  He was here yesterday.  Garrett installed the unit in about 3 hours.  Great to have a cool garage for my home workout. Would definitely recommend Stay Cool for any need.

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 identified an issue previous AC specialists didn't. A cap on the tube before the p-trap was missing. Led to fire truck rollout due to water spilling into the smoke alarm. Kevin didn't charge. He is trustworthy, fast, and highly knowledgeable. Recommend him for system checkups or repairs. He also will give truthful assessment about system replacement if needed.

Our daughter's house had a plumbing issue and water leaking from the kitchen. I had called a couple other plumbing companies in the area but no one could come out right away, some were booking 2 weeks out. I called King Plumbing around 2 pm. The repairman arrived before 5 pm and had the repair complete inside of 1-2 hours. I cannot remember the name of the gentleman that did the repair but he was courteous, knowledgeable and helpful. The cost of the repair was also reasonable. I do recommend this company and will use this company again if needed.

Mark F and Salvador came to my home on Tuesday, 01/25/22 to install a surge protector and write up the four-year maintenance contract. I explained that I worked from home and only had an available time slot from noon to 1p.

Mark explained the importance of the maintenance agreement and the surge protector they installed for us last year. They arrived at 12:10 p and were done within 20 mins.

I was very grateful for their timeliness as I just started a new job and they are very strict about the set in/out times during the day. Thank you for your service.

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.

Friday morning, just about to finish my shower and I go to shut off the water and the handle comes off in my hand. The water is still on full blast and it's hot as hell. I've got no way to shut it down. The top of the stem is still in the handle. It twisted right off.
I quickly dried off, through on some clothes, and headed out to the garage and shut off the hot water at the tank. Hot is off but still have a little cold running. Time to call a plumber.
I ask Google for a plumber in the Sun City West area. I get a bunch. Call the first...they can't come today. Call the second...cant get there till Monday. Third was Canyon State...She told me they could have a plumber there in two hours. Great, I said.  Send him over.
He came on time, fixed the problem (it wasn't easy) in an hour and he was gone.
The availability was great, he was very professional, (knew what he was doing), and the price was reasonable. I couldn't have asked for more. I've never used them before but they will be my first call next time.
