“This is the first time that I had Douglas Williams come and do my fall maintenance. I was so impressed with his knowledge and friendliness. Had to leave a review because he was so thorough and always had a smile on his face.”

“ESA provided excellent service with my heat pump replacement. Dean was very professional, returned my phone calls in a timely manner and came by the day of installation to make sure all was well and asked if I had any questions. Their installation team arrived on time, covered the work area with care and were courteous/knowledgeable.” – Irma R.

“We would like to recognize Nicholas for his outstanding efforts in troubleshooting our recent issue with our furnace thermostat. We called ESA because our thermostat screen would turn “blank” several times a day for several minutes. Initially he thought we would need a new thermostat unit, so a followup appointment was scheduled for the next day for installation. When he returned, he told us he had thought about this problem and wanted to check some other things in our system, thinking perhaps there was another problem causing the thermostat to shut off. After some more investigation, Nicholas found that the fan speed was set too low during the new installation last year, which was causing excessive heat and tripping the system to shut off. This solved our problem, and he saved us over $400. We would like to commend his diligence and motivation, since he was thinking about this during his off hours. It demonstrates that he is a very capable technician who should be encouraged towards more responsibility and higher level work. Thank you!” – Audrey K.

“ESA installed our air conditioner and gas heat units 22 years ago. When our AC unit stopped working, ESA came right out, assessed the situation, and explained our options. In the few days that we were without working AC, ESA lent us a portable room air conditioner unit, which cooled our main living area nicely. Our new AC is wonderful!! The ESA technicians are fantastic and take care of every detail. Upon completion, the system was explained to me in detail. I highly recommend ESA for all heating and cooling needs.” – Jane J.
