Mountainside air was a lifesaver! Our AC went out late Saturday night and I called early Sunday morning to ask for help. They had a technician out to our home within an hour of our first call, and that technician was able to fix our AC and get us back up and running the same day. We are so grateful that we contacted mountainside air and we highly recommend them to any family needing help with AC!!

These guys are great. Always do a thorough, honest job at a competitive price. I have them out twice a year to two different homes. They've done a full replacement for me as well as other work. They are my go-to AC company from here on out. Keep up the good work, guys.

I can’t say enough about how amazing the team is at Mountainside Air. They are knowledgeable, friendly, professional, on-time, and know how to treat customers. I’ve been looking for an HVAC company for a while that can help me keep up my maintenance on my AC units and am thankful that I found them. Call them and they will help! I’m this day-in-age it’s hard to find people that are willing to do the right thing and Mountainside Air are those people. Thank you Steve and Tom for saving me from the heat!

I reached out to Mountainside for a thermostat replacement a few summers ago, and they understandably were unable to help due to high demand. They were polite and professional in their response, so I saved their number for the time that I would need to replace my AC unit.I reached out a few months ago about a noise my current unit was making, asked them to check it out and quote me for a total replacement.They fixed the noise issue without charge and sent me a quote the same day. The quote had 3 options based on the unit I wanted and how much I wanted to spend.I sat on it for a while then realized I needed to get this done before summer. I was so pleased with the services and communication so far that I did not feel I needed to call around for other quotes.I asked Mountainside to call me to schedule an appointment to check this off my list, and they came out 4 days later.Their trucks are well marked, their crew was clean, respectful, and knowledgeable. It took 3 hours for them to fully replace my unit and haul away garbage.They use an appointment system that kept me well informed about the quote, scheduled appointment, and day-of arrival time, which took a lot of anxiety out of this process.I am so impressed with this team and look forward to maintenance visits. Even though this is an expensive part of homeownership, Mountainside Air was worth every penny.:) thanks guys!

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
