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…

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. Mountainside won me over with every aspect of company. From the professional phone call in the beginning to the handshake after the installation. A few months…

Mountainside Air continues to be the best service company I’ve seen in a very long time. Yesterday I had a new team member from Mountainside Air, Clayton, come out way after hours to make a small repair. Fantastic work. Highly recommend them for your HVAC needs!

I’m very happy with my experience with Mountainside Air. My AC stopped blowing cold air and even though I didn’t call until 5pm they had someone to my house by 6:30 pm. Tom was very professional and thorough, taking the time to explain everything he was doing and what he saw including showing me pictures he took of…

Great service, very personal service technicians as well. Small shop with a great attitude and appears to care about its clients needs. Doesn’t try and upsell you on a new AC since the technicians are not commission based employees.

Of course our AC went down on Saturday night when it was 115 degrees out. Mountainside was very responsive. Clair who I spoke with on the phone Sunday morning was kind and understanding and they squeezed me in just a few hours later. Found and fixed the problem as they had the part on the truck. Couldn’t have…

I can't express how happy I am with their service. My a/c went out in the middle of the night. All the big a/c companies were booked out for 3 weeks. Seriously, no joke even for emergency calls. My husband's co-worker knew these guys personally. I called them and within 2 hours they were at my house. They had the…
