Contacted Tom at Mountainside Air to take a look at the AC unit at my Dad’s house. Another company had told him 5 times there was nothing wrong. Tom showed up on time after caLong me in advance and letting me know he was on his way. He went through the operation of the unit for over an hour and found a faulty contactor switch. (This had just been installed the week before by the other company). Tom changed it out and ran the unit and so far it is working great! He charged a fair and discounted price for his service and left with my dad feeling satisfied and speaking highly of Tom and his service and communication. Tom and his brother Steve have provided excellent service not only to my Dad, but at my house and my daughter’s house. If you are looking for a trustworthy and fair AC Service company I would highly recommend Tom and Mountainside Air.Thank youSteve

Heading into summer our 12 year old unit wasn’t keeping up. A friend highly recommended Mountainside Air, so it was my first call. Tom arrived as scheduled. He quickly determined the issue (low freon) and was able to get the unit operating as it should. He additionally looked over the system and mentioned that low freon typically means a leak somewhere in the sealed system and that if we wanted we could schedule a leak test if needed to further t-shoot. Which we’ll do at some point after summer. If you're looking for a professional, trusted company that will do an excellent job and explain what you need and not try to sell you what you don't need, you found them. When we’re ready to replace our ac, will use them as well. Thanks Mountainside air, you have another happy customer!

Woke up to a dripping vent and wet walls! It’s Monsoon season in AZ and its hot and very humid , and A/c repair is super busy this time of year, so I was not sure I could get someone out to my home same day to check out my issue! I had used Mountainside a few years ago and was very impressed with the service Tom provided so I called them again! The scheduler got me an appointment within hours of calling . The tech came out , and after some discussion on what he thought it could be and him going up in my attic a few times to investigate the secondary unit he finally got the leak under control. The pricing was very reasonable also! This is my second positive experience with Mountainside and I will use them again in the future and would recommend to others.

Christian and Clayton are the best! They were quick and efficient. They fixed my air conditioning unit and the house was cooling down even before they left. I would highly recommend!

Mountainside Air installed our 2 new units 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.Just had Cristian and Raul come out to replace our air filters. They were on time and quickly got the job done.

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!!
