"Had new hvac, furnace, and hwh installed. Furnace had a couple of air leaks between a coil and furnace which I fixed myself. Hvac was spot on. Hwh failed first inspection, but was corrected in same day. For the premium price paid, these issues should not happen. Quality 4.5 because of these issues, same goes for value. Customer service is very good. They are very professional, work looks very good, clean worksite afterwards. I would recommend, but don't think about negotiating price with them. Their labor is very high."

"We chose Total Comfort Heating & Air Conditioning, LLC to replace our 40+ yr old HVAC system. The salesman (*Ken Ross) was knowledgeable and friendly. No hype, no sales pitches and no up selling. The Installers were punctual, pleasant, fast, and left the work area spotless. I would highly recommend this company to anyone in need of quality HVAC Services."
