Christian did my HVAC maintenance today (6.5.26) and he was super knowledgeable, friendly, and fair. He let me know what I needed, even though it wasn't great news, but I kind of expected it since the unit's over 40 years old. He even showed me photos and videos. I totally recommend Mountainside Cooling and Heating!…

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…

Professional, polite service. Cleaned everything up when they were done. Honest, competitive pricing. Also gives back to military personnel over seas with care packages.

Tom was AMAZING! I called yesterday because our house was freezing cold with our new ecobee system and we didn’t know how to adjust it. He first tried to assist me over the phone and then they were able to schedule me for the very next morning for a visit. He was efficient and helpful in explaining the system and…
