Best in Phoenix AZ

Paul was the technician that serviced our A/C for routine maintenance. He was prompt and I also received a courtesy phone call with ETA before he made his way over to our house which I GREATLY appreciated. He was very professional and explained the work he had completed and also the proposed preventative work he recommends we get done to ensure our unit lasts as long as possible before having to replace it. I recommend Northern Air Mechanical Services and will continue to use them for maintenance services and repairs if ever needed.

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.

Just new in Wickenberg and bought a condo.  Within 5 days the old air conditioner dies and who do I call?  I go onto a HVAC website and ask for suggestions.  Immediately I am contacted by Jason and he asks if he can help.
Besides coming to see if the unit can be fixed, he has Lola bring a temporary unit to get us by until we have permanent air conditioning.
Can you ask for better service?
The next day, at reasonable pricing, we are back up and running.  We chose to go with a whole new unit to replace the 30 year old unit.  Mitsubishi non-duct.  What a beautiful unit and installed by very friendly, professionals.
I would recommend them to anyone.

Andy Hobaica is the man! Always responsive and such a genuine and honest guy. You know you are getting the best every time his team is out at your home. I've used them to service my home and referred them to multiple family members!

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!

Completely replaced my HVAC system. When they came out for the estimate the guy did research beforehand and knew when my house was built and sqft. I mentioned I had a swamp cooler that was no longer used and they brought a crane by to remove it in addition to replacing my system. They were done in a day and I had my entire system from the 90's replaced. Great experience and highly recommend for quick work at a good price

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

Great guys to work with.
Answered call after hours.
Came early next morning.
Replaced air handler and had us up and running in a few hours .
Will recommend to all!!'

I am updating this review because, to their credit, the owner contacted me immediately.  He made every attempt to correct this and stated that they do normally inform prospective customers about their maintenance areas. I am completely satisfied with his response and appreciate the customer service.  I will add, when the install took place I was very satisfied, the work was on time, professional and exactly as we agreed on. I did place a call to them a couple of months after install with a question and got an immediate response.

This is the best AC business I've dealt with anywhere. Reliable, polite, professional, honest, and competent. Reasonable prices. And they don't try to sell you a bunch of crap you don't need. Highly recommended!

Willy was the EXCELLENT field service engineer who visited our home. He was kind, honest, and efficient. We called this company and Willy was able to visit that same day. I will definitely be recommending this company to friends and family.

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 had Quantum perform a checkup on our system and are extremely satisfied with the service received. They arrived exactly when they said they would and got it taken care of. We had been told in the past by several other companies that there was an issue that needed to be fixed and would be fairly expensive. Kevin checked it out and dispelled that. He identified a minor issue that may come up but nothing that needed immediate attention. The price for the checkup was very reasonable. We also like that they are a small, local company. We will definitely look to them in the future any work needed on our system. We highly recommend them. Thanks.

Called this morning and Brendan was at our house in less than an hour. He was very nice and explained what he found and what he did. Hopefully I will not need a plumber for a long time but if I do, I will be calling King again!

Been in my house for about 3 years and I wanted the system checked out as the house is 5 years old.  So of course they come out and find an issue with the capacitor.  Out of the 6 times that they have come to my house (other houses I owned), they have said that I needed a new capacitor either on the outside system or on the inside system.  Guess what happened this time?  I need a new capacitor.  So they tell me the price of the part and labor and said it would be cheaper to get the 4 year contract.  I did this with my other houses and I also did it for this time.  I also was told that the motor was leaking oil but it is running fine.

6 months later, on a 114 day in July, the blower motor locks up at night.  I log a ticket via the website at 11pm that night and get a call the next morning.  I get told that no one can come out till 5 days cause they are busy.  Wait, but I am not a higher priority since I have a contract?  You would think.  I tell them if they get a cancellation, give me a call.  They end up coming out 2 days later.  I guess that is better than 5.  The technician comes out and tells me a new motor will be over 1k.  Of course I saved a lot since I have a service contract...Yeah (sarcasm).  Of course it is hot, and I am pissed, and I don't understand why the other technician that came out 6 months earlier could have just have it replaced then.  I ended up renting a portable AC for one of the nights and that didn't work.  So the next night I take the family to a hotel.  Of course I have to take time off so that pissed me off even more.  I was just irritated about the whole thing.  Then we get told he might not be able to come out till the afternoon the next day.  At this point, I say what ever.

The next day arrives and I get a call 8am in the morning.  Woohoo, they can fix it right now.  He get's out there and pops it in.  Yes, finally we get cool air again.  

So this review would be a 2 star if not for James S.  Even though I was livid and irritated throughout the whole process, he was very professional and answered all questions.  He made it a point to make sure we were one of the first customers that he had to service in the day.  I appreciate everything James.

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.

I needed a new Heat Pump and wonder who would be the best place to replace the unit. I went to their store and talked to Mike, a sales consultant. After going over price, size, and when I could have a unit installed, I decided on Canyon State Air Conditioning. They show up on time and worked nonstop until it was finish. I was very satisfied with the installers. James and Victor made the installation enjoyable. After they got done installing the unit they came in so they could finish up the process. They explained to me how to run this system and all about their company. They made this a very great experience.
