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 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…

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…

Tom and Mountainside air installed my new AC unit. As a landlord I was in a time crunch to get a new unit in. I reached out to a few different companies.

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.

We had purchased a new house with a faulty HVAC unit. Tom was able to stop by to look at it the same day we found out we needed a new one. From the start, we were very happy with the professionalism, quality, and follow-up that we received when removing our old 30 year old unit and installing a new Goodman unit. The…

Amazing to find a business that is outstanding in AC install & repair. This company really is for the customer. Unlike others which I’m not allowed to give names. I’m a senior live alone in country 50 miles north of Phoenix. When my ac went out I was terrified. No ac company will come this far. My son found Tom &…

Our parents A/C was probably going, and with parents in their 80's, we couldn't have that. Called and Claire got us is the same day by noon. Tom was right on time, and was great about waiting for my sister to get there, my parents don't do well with strangers. The unit had frozen up and had many small "unrepairable"…
