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!

*Updating review after speaking with the owner Tom who addressed and resolved my concerns appropriately.AVOID at all costs. Replaced AC motor for $1,121 on Wednesday 10/4. Three hours later AC was randomly turning off. They came out again and said it was a separate wiring issue. 36 hours later AC is blowing hot air. Find it really hard to believe that 3 separate things broke as a coincidence within that timeframe. Seems logical that the wiring was jostled during the multiple hours fixing problem #1, especially given the fact that the tech commented that it took longer than expected. That's really reassuring. Save yourself the headache and additional expenses and book a better HVAC company.

We experienced an A/C failure the night before we were supposed to leave for vacation. Unfortunately, my 80 year old mother was staying behind so we couldn’t leave until someone came to look at our unit. After calling a few places, we found Mountainside Air and they scheduled a same day appointment for the afternoon. The tech, Josh, was on time, very helpful and while he wasn’t able to fix our 25 year old A/C, he did provide a lot of helpful information to get it fixed or replaced. I will definitely call Mountainside Air again when we have a problem.

Mountainside was fantastic to work with. We called on a Sunday morning, when it was 95F inside and they responded immediately. Due to the extreme heat wave they had to schedule us out one day, but they brought several portable AC units to keep the house livable. The owner, Tom was the one who took the call (again, on a Sunday!) and gave us an immediate, firm quote for both a repair and a new system. Everyone else we spoke to, wanted at least 24 hours to send us an estimate, which, when your home is dangerously hot, those hours are critical.Mountainside's quote was so amazing, it was actually $500 cheaper for us to put in a NEW unit, than it would have been for a REPAIR with any of the 4 other, top-rated companies on Yelp.We now have a new system that has a 10 year warranty, that is working beautifully, keeping our family cool. We also have a phenomenal go-to for our HVAC needs for ourselves, friends and family.

I’ve worked with other AC companies in the past and always felt like they always wanted to up-charge me for repairs that weren’t even needed. Not with Mountainside. I really appreciate their honesty and my AC is working just fine now because of them.
