Best Heating & Air Conditioning/HVAC in Phoenix, AZ

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.

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.

Ridiculously and surprisingly excellent service! I got a referral from my dad who had used them before and of course I trust who my dad would trust but I didn't expect to get a free inspection just by dropping my dad's name. Usually you get a credit or discount if you are the one who refers someone, to be applied on your next service but in this case I was the one who got a free inspection because my dad referred me! I was thrilled! The technician was professional, never pushed anything that I didn't need but he did recommend a part that he said looked worn and would likely need to be replaced in the near future. Don't hesitate to call 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!

Called comfort experts for annual maintenance for the HVAC on our house and Ryan was great! He inspected everything including the blowers in the attic, and clean the coils on the outside unit. Not only did he find a part that was worn out, but he informed us that although our unit was working great, the old style of a/c is going to be phased out in 2020, so repairs/replacement will become more expensive as the parts get used up, and gave us pointers on what to look for in the future.

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

The owner, Danny, came out and took a look at my AC and found an issue and fixed it right away. He said if I had any more issues to give him a call or send him some videos. I'm much happier now that he came over and took a look at what was happening. I will definitely give him a fall in the future if anything happens. Thank you!

These guys are great. I lease a townhome  that has had AC issues since i moved in and Sean, Nicole and the entire team have been great in working around my travel schedule to get work completed. Highly recommend Reliance !

I CANNOT say enough good things about this company!  Every part of my experience with them was top notch...from the initial call I made, I had a great feeling about choosing this company.  Customer service was amazing...answered my questions over the phone and on site, called back to confirm I would be home, etc.
The technician (Joe) was polite, professional, and took the time to sit down and explain to me what the issues were with my AC.  (And also gave me some great pointers about air filters!)
Repairs were made promptly after the issues were diagnosed and the technician had all the necessary parts on his truck.  
Prices seemed very reasonable, and I never once felt like I was trying to be 'upsold' on what was needed.  
A+++   Will recommend highly to all of my friends and family!

I called Day and Night once again to come out and repair my unit so we would have heat for the winter months. I continue to be impressed with their customer service and their work.
- When I called to order the the part I needed and schedule the appointment, the lady on the phone was very helpful, adjusting their schedule to accommodate my work schedule. She knew exactly who I was an why I was calling, having my information in their system.
- She was upfront and honest about the time it would take to order the part. She also asked if I wanted the maintenance package I was interested in from the last visit. I was but unfortunately time did not permit for the repair and the maintenance check on the unit.
- Philip, the tech from before, arrived once again on time. He had another tech with home to replace the needed part but also offered to run the maintenance check as well. With the two of them they were able to go the extra mile and get everything I needed done to the unit in the original time that I was quoted.  
- Philip and the other tech were great. They got to work right away and got the job done right. My home and my family are warm. Day and Night not only provides quality products and service they provide a sound peace of mind.

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!

Quantum is by far the best AC Contractor I have ever used. I called for service around 8:00AM and Kevin was at my house a few hours later to look over my system. He was very honest and did not try and sell me anything that was not needed. He had my system up and working in a few minutes and his price was fair.

King Plumbing is awesome!! Terry is great about answering phone calls and he is so honest. Brendan is the best plumber ever. He always comes out right away, within a few hours which is very impressive. He is professional and kind and a pleasure to work with. 5 stars!!!!!!!!!!

We made an appointment with Precision five days ago and they were supposed to come today. They called this morning to say our appointment would be delayed, but someone would be out this afternoon.
Precision just called back to say they are overbooked and no one will be out to our house at all today!!
How can you make an appointment with a company so many days in advance for them to cancel the day of??... After we were accommodating enough to move the appointment to the afternoon, nonetheless!!!
Very disappointing. Poor reservation schedule obviously. They weren't even apologetic. We will never be using this company ever again!!!!!

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.

Worst company ever, always rescheduling, adding extra bogus charges, and super unreliable
