"Excellent service from Hecomo. Technician did not try to push purchase of a new HVAC system even though there were major issues with our system, feel comfortable while talking with an advisor. Very knowledgeable, patiently, friendly and nice person, answer all my questions. Later on, we decided to replace the whole new system with fair price and wasn’t ripped off as others. Very professional and well trained technician. I will definitely use them again."

"I got four estimates before choosing Michael Bonsby. They were the only HVAC contractor to actually measure my house and recommended a system based on those measurements, which turned out to be a smaller and more affordable unit than my existing system. The other three just assumed the existing system was properly sized and proposed replacing it."

"Outstanding service and work. Very happy I chose them. I had an air handler/HVAC unit that was old and dirty. They came in, took it apart, cleaned/sprayed/lubricated the unit, put it back together, and it works so much better. Thank you!"

"Patrick came out the same day I called him, even though it was a Saturday. He was attentive to the problem and all the details I provided, as well as thorough, efficient, and charged very fairly. I was sure my hvac needed replacement, but after a few quick measures and parts replacements, he got the job done in several hours and the house feels satisfyingly cool again! Highly recommend!"
