The HEP Tech Patrick McGraw worked with my vacation schedule to get the coil in my HVAC unit installed. Weather forced him to reschedule twice and he responded by coming the day after we returned from vacation. He showed my wife the old damaged coil ( I was detained at that time), and we checked over the repair together. While I was a little disappointed in some original scheduling snafus, Kevin did a great job and gave us his contact info so we could request him in the future. Overall very satisfied.

Reliable Heating and Air Conditioning Service in Dunlap by HEP

Dunlap’s rolling hills, four-season climate, and Southern charm make it a beautiful place to live. Yet the same climate that offers crisp winters and humid summers also places enormous demands on residential and light-commercial HVAC systems. HEP delivers comprehensive heating and air-conditioning solutions designed to keep Dunlap homes comfortable, energy efficient, and healthy all year long. This in-depth guide explores what the company does, how its technicians approach every service call, and why routine HVAC care is essential for residents of Dunlap and the surrounding Sequatchie Valley.

The Climate Challenges Unique to Dunlap

While averages can make the weather seem moderate, Dunlap regularly experiences winter lows dipping below freezing and summer highs in the upper 90s.
