Alice M.

"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."

By pairing high-efficiency equipment with meticulous workmanship, the team ensures homes stay comfortable all year long while helping residents lower utility costs and improve indoor air quality.

Why HVAC Unit Replacement Matters

Over time, older systems lose efficiency, drive up energy bills, and struggle to maintain consistent temperatures. Replacing an outdated unit with modern technology offers immediate and long-term advantages:

Enhanced comfort with steady, even airflow
Noticeably quieter operation
Reduced carbon footprint through energy-saving components
Improved humidity control and filtration for healthier indoor air

After gathering data, HEP technicians recommend heating and cooling solutions tailored to Tennessee’s varied climate zones, selecting from:

High-efficiency split systems
Dual-fuel heat pumps
