“Our heat stopped working in the middle of the night and the real feel outside was -15 degrees. Worried that I was going to have to wait forever and/or pay an arm and a leg for someone to come out, I made a call and they had someone there in about 1.5 hrs. They sent a text with the technician info and called just before arrival. Boi Za arrived and he was super friendly, helpful and explained everything in understandable detail. They have a maintenance plan we signed up for where they come out 2xs a year and clean and check the unit. We will continue to use this company for all our HVAC needs and request Boi Za as our technician.”

“Used them for an air duct cleaning/ humidifier change today, super nice, efficient and very courteous of my 3 dogs, and toddler! Techs were very friendly, and cleaned up after themselves! Used them in the summer time for a/c maintenance, and will continue to do so!!”

“Richard was EXTREMELY thorough with the yearly furnace maintenance. He took the time to walk me thru deficiencies and gave an explanation for the work that needed to be done. He found several things that the previous technician had not addressed. He was very kind and respectful and a true blessing. I would highly recommend!!”

“Nothing but amazing! We have had the pleasure of working with Carter the last few times. Originally, he came for a regular inspection and tune up. Then, he came about a week later and installed our new thermostat. Both of these, times he was professional, friendly, and explained everything. Then, the heat stopped working over the weekend. After playing around with the new thermostat, we placed a call for an emergency service call. It took several hours (they were slammed with calls from the weekend storm), but we again got Carter. He went right to work, identified, and fixed the problem within 30 to 40 minutes. Again, he was professional and friendly. This kind of service is why we are loyal customers and club members.”
