I have used Mountainside for going on the second year now, and they're always great. Responsive, helpful, and explain everything without trying to upcharge or extort me like the bigger chains in the valley do repeatedly.

Christian did my HVAC maintenance today (6.5.26) and he was super knowledgeable, friendly, and fair. He let me know what I needed, even though it wasn't great news, but I kind of expected it since the unit's over 40 years old. He even showed me photos and videos. I totally recommend Mountainside Cooling and Heating!…
I first and foremost just want to say that Jaymes is a good dude. He had good energy and came into our home excited and eager to help. He explained everything about the process of getting a new HVAC unit. It can be stressful because that is a huge purchase and a lot of moving parts that go into making it happen. It…
I cannot say enough about Montainside Air. Same day service and very reasonable rates. I will not change AC companies again. Tom and Steve very knowledgeable and professional. Updated: New AC system installed, and works like a dream and really cut my electric bill. Update: Condensate clogged up and again…
Very very respectful, informative, fast working, organized teamwork, well spoken, hygiene plus, Handsome,. Loved their work ethic will recommend.
The team was excellent, nice and very detailed group of guys. They took their time to make sure everything was working as expected, taking no shortcuts.
Mountainside air was awesome to work with. They gave us a fair price and their workmanship was above what was expected. Customer service is great. The system we got is so quiet we can not hear it inside the house at all. The air stays at a constant temperature. We love it. Thank you
Super fast, friendly, and affordable!
Installed new ac. Whole process was quick and they cleaned up everything before leaving. Got many quotes and the price seemed fair. So far so good.
Mountainside arrived on time and performed Mini Split install in a clean and professional manner.
They don't get any better than this. Topnotch!
I really like Mountainside Air. They were willing to write back and forth with me because I am deaf. They explained everything clearly. They had a lot of patience with me and listened well. They installed a new HVAC system (air handle, unit, thermostats, and grill ventilation) and did a high-quality job. Good…
We recently had Mountainside Air install a new AC unit for us, and the whole experience was fantastic! Raul, Abraham, Josh, and Mike did an awesome job from start to finish. The new system was up and running right after they finished, and they made sure everything was cleaned up before they left — super professional…
Outstanding work, great people !!!
I called during the hottest day of the year, July 9th 118 degreesand Tom answered the call and his technician, Christian was at my house within half an hour. He diagnosed my A/C issue and determined my system compressor was about to fail. Christian remained here and gave me a quote for three different systems. We…
They were very professional and timely as promised.
Been using mountainside as my sole HVAC contact since buying my house in 2018, they have installed a new AC on my house and even in a yearly check up their techs are constantly looking for ways to ensure your system is running efficiently. As long as I live in Arizona, I will use Mountainside for my HVAC needs, no reason to go to anyone else.
Very satisfied on time excellent work and clean up.
Very quick to fix your problem and work with you on a new unit. Very professional!
All awesome individuals clean and hard workers did a great job and left everything clean. I would highly recommend this Company. Very fair pricing also.
We finally had to have our 20 year old A/C unit replaced. When I reached out to Mountainside Air they were responsive and I could tell they were concerned with getting us what we needed. Tom made the scheduling easy through the entire process and the communication about appointments and the quote were thorough. The…
Top notch company from estimate to install and even clean up. I would highly recommend Tom and his crew. They are clear and no BS. Super happy with my decision on choosing Mountainside Air!!
I wanted to be proactive instead of reactive when buying a new AC unit. I called many companies and then I called Mountainside Air. Tom and Steve are down to earth gentlemen. They came over and were very honest, I showed them my other quotes and everything was transparent. My gut said I can trust them. My gut was…
Knowledgeable, professional, and quick services, I have full confidence with the team at Mountainside Air Conditioning & Heating for any upcoming projects or servicing needs.
Excellent customer service, quality and professionalism. You can't go wrong with Mountainside Air. Peace of mind receiving service from someone my husband and I can trust is priceless. Thank you to Tom and his brother!
