Best Heating & Air Conditioning/HVAC in Phoenix, AZ

Sold our house, and the buyers inspection revealed a couple of issues we didn't know about. A/C drip pan in the attic rusty, and drain line possibly plugged.
Since I had such a good experience with this company a couple of years ago, gave them a call.
Efficiently scheduled appointment. Technician showed up on time. Thoroughly professional gent fixed the problems for the price I was originally quoted. I highly recommend this Company. Their standards and behavior have been exceptional!

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.

We thought there was something wrong with our AC, but they came out and checked it for quite a while actually. Our AC units were fine and they didn't charge us a thing. And this was during the high heat of the summer!

Honest, friendly & reliable service from person who answers the phone to our service tech, Mark! We replaced our unit through Hobaica because they gave us best pricing for unit & labor. Since then, we have had excellent customer service!

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!

After waiting on an AC guy for weeks I decided to give comfort experts a call. I requested quote Ryan was at our house within an hour. Diagnosed problem, ordering parts and will be back to install tomorrow. Very prompt and professional. We will be using them in the future! Thanks again, Ryan!

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

Danny the owner from K&K Heating and Cooling took care of me, I needed a new 4 ton heat pump 14 SEER system installed, he unlike, a few of the others who bid on my job, didn't try to upsell me anything I didn't need. (it was amazing what some of the sales people told me I needed extra, which would have added $2000-5000 to the price).
He was fair and reasonable on the price. He even checked out and serviced my other AC system to make sure it was cooling like it should, at no extra charge.
I had another company who wanted $1,500 more than K&K for the same system, but with an enhanced compressor, not more efficient but enhanced. LOL

Highly recommended

I have used Reliance multiple times over several years.  We have investment properties, in which we've used Reliance to repair or install new A/C units. They have always exceeded our expectations as far as workmanship and customer service.  At one point, Dalen was up in our attic repairing an a/c unit, and he noticed our central vacuum was disconnected, and he fixed that! These people couldn't be nicer, including the office staff.  This morning we called Dalen, an a/c unit wasn't working, and within 2 hours, someone was out and our unit was repaired.  They never overcharge, or replace anything that can be repaired.  I highly recommend this company.

I had AccuTemp come out to have a look at my 10yr old AC unit. Staff is very friendly and polite. They spent about 25min looking into why my AC unit wasn't cooling as it should, then made recommendations on what was needed to fix it.

The repair was done in a timely manner...had to wait for a replacement part, but the repair man came back and installed the part as soon as it had arrived. Only charging me once for the trip and not a second time as some other companies do.

One of the recommendations was to redo my duct work as the living-room wasn't getting enough airflow...the quote for this was a little high as I had a second opinion and they quoted the same job for far less.

All in all I am happy with their services. Their maintenance plan is a good choice.

Just had Day & Night do a pipe repair in my leaky ceiling. Troy came out and was an absolute professional. The level of service, amicability, professionalism, and expertise were unparalleled. I know enough about plumbing to have a conversation (not enough to fix myself) and I could clearly tell Troy was being honest and truthful with me and giving me the best possible advice. I will definitely be requesting Troy's services next time I contact Day and Night for help.

My experience with the company as a whole was awesome as well. I asked for a quote and they reached out to me right away and were able to schedule an appointment very quickly. I spoke with Maria on the phone and she was friendly and helpful. The charge for the work was also very reasonable and comparable to other quotes I received, if not cheaper. I will be using this company again and would recommend them to a friend.

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.

Garrett with Stay Cool just showed up an hour early and fixed our heat pump that had been out since last Friday. You don't realize how amazing AC is until it goes out! I highly recommend Garrett and this business!

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!

We were referred to Kevin through a friend that had recently used Quantum. He didn't disappoint! He took the time to go through all of our new AC unit options as well as the current available SRP rebates. His crew was on time and finished the job early. Kevin then took the time to walk us through how the new unit worked, the thermostat settings and how to apply for the rebate. Finding businesses that value their clients is unfortunately becoming more rare. I was blown away when I received a package in the mail from Kevin with all the rebate docs, envelopes prepared for mailing etc. He made the whole purchase process very easy and went the extra mile. in addition, he followed up a week after install to ensure everything was functioning properly and to answer any questions. I would definitely recommend Kevin with Quantum and I don't say that lightly.

Today was my second time being thoroughly impressed by this company. They were able to come out to my house within a couple hours of calling, they were highly professional and were able to successfully fix my a/c quickly.

I highly recommend this company!

Appreciation shout out to Justin Cox and Chad Hood for their speedy response to my no heat situation.   Thank you.

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.

Last Thursday at around 4:30pm when my wife got home she realized our upstairs AC wasn't blowing cold air.
We discussed for a moment waiting till I got home to take a look at it (since I do many of our home repairs myself) but quickly concluded that we should get a technician out to our house ASAP or we'd likely need to wait till the next morning.  My wife called Canyon State a few minutes after I got off of the phone with her (maybe 4:45pm) and was pleased to learn that a technician would be out to our house (we live in Surprise) between 5 and 7 pm.

Astonishingly, the technician (Jake) knocked on the door shortly after 5pm!

He quickly determined that the problem was with the outdoor unit corresponding with the upstairs AC (a motor had failed, and the unit was evidently SUPER hot)

We approved the replacement for that motor, and by 6:10pm I was paying the bill for the completed repair (using a slick iPad app - which wasn't really a factor, but was cool to see how they were using modern technology to make transactions easier).

We had a cool upstairs by bedtime, and I couldn't be happier with how everything went.

If anything breaks again, I'll definitely be calling Canyon State (saved them to my phone as a contact :)
