Gas Furnace Repair in Columbia, MD 21044

“I have been a customer of Environmental Systems since 1976. I would like to recognize Maureen(office contact) and Scott (our tech) for an outstanding job recently done for us – last week before the snow began we had no heat-Scott had someone troubleshoot our Carrier model and came to our home twice to make sure the proper repair was done before the storm. As a seasoned (older) realtor I have provided Environmental's name to many clients thru the years they provide outstanding service in a very professional manner.” – Elaine K.

Air Conditioner Installation in Elkridge, MD 21075

“I can highly recommend ESA. Installation of a new AC and Furnace was scheduled within one week after placing the order. The space for the furnace was very, very tight but Ryan L. and his team fit in the new one just fine. (The original furnace was put in when the house was built before they put up the walls…). They showed up on time, cleaned up after they left, they handle the warranty registration, permit, inspection, rebate submission etc. Very Happy with their service.”

Gas Furnace Maintenance in Columbia, MD 21044

“Steve of Environmental Systems Associates provided our semi-annual AC/H checkup. He showed up exactly on time (and brought in my newspaper with him). He was extremely friendly and helpful, taking the time to fully explain a number of setting options on our automated thermostat relating to humidity settings in the heating mode vs the cooling mode. His inspection and maintenance of our systems left me confident that they are in good shape and will get us through the winter. He also gave me his card and offered to personally answer any additional questions that come up. I award Steve "5 Stars" for friendliness, helpfulness and thoroughness. He is recommended without reservation. Thanks again Steve and hope to see you next inspection.”

Heat Pump Maintenance in Columbia, MD 21044

“Your service technician, Ivan G, just left my house after providing the semi annual maintenance service to my 3 heat pump units. I would like to commend him for his efficiency, as well as his outstanding professional manner. He seemed very knowledgeable in responding to any questions I posed and performed his tasks with diligence. He was very polite and also tidy. I would like to request that he be the dedicated service person to return to our home for all contracted maintenance services. Thank you so much.”

“Great service and fair pricing, I will be using environmental system for all my future ac and heating repairs. Came out same day my ac failed and repaired on the spot. I even got an invoice with pictures of what had caused the issue.”

ESA is the best! Would never go anywhere else. We used them for an AC replacement and they were by far the most helpful out of everyone we called, and their prices were fair/in line with others. They also have a good maintenance plan. They do a great job!

Matthew and Ryan did a great job with the install, completing a complete removal of old HVAC system and install of new HVAC outdoor and indoor units.They finished the install in one day as promised, which was important to me due to a next day family event. They managed this even though the outdoor unit system delivered in the morning had been damaged in the warehouse - not visible till unboxed. They managed to locate a second system, and get it installed all in one day as promised. The salesman, Richard Dean also stopped by several times to make sure all was OK and was instrumental in getting the second system from the warehouse. They were all friendly, neat and knew exactly what they were doing.I highly recommend them and give them the highest rating.

My experience with your company was excellent! The salesperson Bob Galla explained everything that was needed in the process, he identified and advised all the repairs needed for vent and the ducts. Bob's proposal and the format I received was very formal; I really appreciated that a lot. He was responsive, knowledgeable and answered all of my questions in a very timely manner. The duct cleaners were very efficient and the installers were so nice
