"I’m very satisfied with the technician Nate who repaired my AC unit today. Apparently, there was a leak and he found it and corrected the problem. I appreciate HVAC Comfort for sending a kind, knowledgeable, efficient and professional technician to my condo. Much appreciated!"

"Called Dash (Airconex Heating & Cooling) to inquire about coming out to look at a loud humming coming from AC unit. He came out later that same day to inspect, most other places couldn't make it for 2-3 days. Upon inspecting the unit, we talked through together that the 20 year old AC unit should be replaced. I dealt with many salesmen in my time trying to upsell, Dash definitely gave me his honest opinion and was more than willing to only do the repair needed to keep the AC unit running. It was my personal preference to go ahead and get furnace done as well as it was just as old. The quote he gave me came in much lower than the others I received. Due to a cancellation, I was able to get in next day. Dash and his son showed up on time and installed both AC and furnace in under 6 hours. I am VERY please with the quality of work done for the installations. I would 100% recommend these guys! Honest opinion, honest advice and all around good respectful guys. Took care of surrounding areas of house inside and outside, great cleanup and removal of units too. DO NOT hesitate to call these guys for an inspection and or an estimate!"
