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!…

Our parents A/C was probably going, and with parents in their 80's, we couldn't have that. Called and Claire got us is the same day by noon. Tom was right on time, and was great about waiting for my sister to get there, my parents don't do well with strangers. The unit had frozen up and had many small "unrepairable"…
