Heat Pump Installation in Columbia, MD 21044
“I began using ESA in 2002 when I bought a home with an existing ESA maintenance service agreement. Every maintenance technician has been professional, courteous, and educational. In Dec 2020, I replaced my HVAC system. The experience has been outstanding. ESA helped me select the high-efficiency system that meets my needs, acquire excellent financing, and EA continues to patiently teach me how to get the best operation from my investment. The phone staff is knowledgeable and always courteous. I recommend ESA.”

“Wonderful experience working with Environmental Systems Associates from start to finish. All of the installers were very professional, and did a great job removing my old system and installing the new one. I was very impressed with the quality of work and the efficiency at which they completed the job. I have now had nearly two weeks to evaluate the installation, during a period of extremely cold weather, and everything is working perfectly.”

Gas Furnace Repair in Ellicott City, MD 21042
“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!”

Air Conditioner Replacement in Ellicott City, MD 21042
“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.”
