I do not live in the US at this time and in so I was a bit worried about choosing a company to replace my AC/heater at my condo in Scottsdale. But from step one all went smooth and felt I could trust Mountainside Air.Recommend them.

It’s rare when a company impresses me. Mountainside air is one of the best. In a world filled with companies just trying to make a sale this one actually only sells you what you need. I had them install an a/c unit last year and they were stellar. Looking at having them install my other unit. Always impressed with their interactions and integrity

Mountainside Air installed our 2 new nits a year ago and they came out for the first spring maintenance. They cleaned the units, checked out our thermostats and changed the filters in the house all for a very reasonable price. We highly recommend them for your HVAC needs. They are veteran-owned.

I called them in the a.m. and they were out in the afternoon. They were professional, efficient and very helpful. We were presented with multiple options and within a few hours we were up and running again. Thank you so much Mountainside Air!

My experience with them was great. I had an issue with my unit on Saturday when all other places were closed but was able to reach them. Raul was my service rep. He was amazing and allowed me to stand over his shoulder as he worked and explained everything he was doing along the way. Overall a great experience!

We were very pleased with our experience with Mountainside Air. They were recommended by our neighbour friends. Their service, professionalism and follow up is exemplary. Tom and Steve scheduled initial visit for a quote and provided us with several options for AC and furnace systems. We had 3 quotes and were really impressed with the warranty for follow up servicing of AC/Furnace units and the pricing of units. Their pricing and service warranty is much better than the 2 larger companies we also had quotes from. Their team arrived on time and worked so hard to get project completed. We feel Mountainside Air is very trustworthy and knowledgeable. We would highly recommend them and very happy with their service and our new AC and furnace units.Thank you to the team at Mountainside Air.Leah & Rene

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 prices than most of their competitors. 100% satisfied. Recommend Mountainside Air!
