Had a wonderful experience with George! He was very professional, patient, and took the time to thoroughly check and properly diagnose the issue!
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.
George was very professional and thorough. I appreciated the time he took explaining everything to me, and I am happy that I set up ongoing maintenance with Mountainside Air Conditioning to make sure our system will always be on the up and up.
They care about you and take time to make sure everything is working correctly. Very nice and friendly. Highly recommend them for service or maintenance.

Rudy, the GM, was extremely helpful and professional, and Christian, the technician, was excellent. Christian took the time to properly…
We love Mountainside Air! Been using them for 6 years. We messed up and called another company one time and they said we needed $2400 worth of work and we said we will get back to you and called Mountainside and they came out and said our AC was fine!!! So don’t get scammed! Call Mountainside Air! Friendly…
Very polite tech and wonderful service
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…
Update (4/02/2026): Cristian from Mountainside Air arrived on time this morning to perform my semiannual HVAC system check up. As in the past, service was excellent.

Great response and efficient, knowledgeable, and friendly professionals.
The total service experience continues after 5/6 years to be exceptional
Albert was my technician and he did a great job. He was polite, professional, and very efficient with the work. He explained everything clearly so I understood what was being done and why. I also appreciated that he never tried to upsell me on anything I didn’t need. He was respectful, clean, and carried himself…
Chris was outstanding and very helpful to us, our dog likes him too! Good job thank you
Love this company! They explain everything, reasonable pricing, great technicians! Highly recommend!!
Mountainside has been quick to respond and send someone out quickly anytime I had AC issues. The tech they sent out (Cristian) was super knowledgeable and polite. I appreciate them not always trying to upsell but always giving the option.
Super nice tech came out and it was very quick. I felt that the assessment was fair and didn’t feel pressured which was really nice. He was also super prompt. I also like that you have a link texted to you that you can track your tech with so you can be ready!
1k$ spent while under warranty. Vague receipt not detailing costs. If I'm spending any money at all I want to see the breakdown. Felt like a car repair ripoff
