Edwin was great…very professional and knowledgable, would higly recommend Mountainside for your AC needs.
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 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 Steve were phenomenal. On time, and same day response. A job well done, and quickly done, thanks to their subject expertise. PROFESSIONAL, FRIENDLY, and KNOWLEDGEABLE. Will be including them for all future HVAC service and repair. 10 STARS ****1 year later and they still got it. Highly recommend.
