AIR QUALITY

On average, people spend 90 percent of their time indoors but don’t know that indoor air can be two to five times more polluted than outside air. The EPA (Environmental Protection Agency) has indoor air quality ranked as one of the top five environmental dangers to public health. It is linked to severe asthma and allergy development in children and to heart problems and lung cancer in children and adults.

DUCTLESS HVAC

The most common HVAC systems are central AC or heat pumps that use ducts to deliver conditioned air throughout your home. Ductless systems are more flexible than traditional systems, because these systems don’t use ductwork. All that’s needed is a small outdoor unit and one or more indoor units, along with access to electricity and a place to mount the units. They are more affordable, can provide healthier air and are easy to install.

Gas Furnace Repair in Ellicott City, MD 21042

January 7, 2021

“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.

Air Conditioner Replacement in Ellicott City, MD 21042

July 15, 2020

“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.”
