“I have been using ESA as my HVAC maintenance company since relocating to MD over two years ago. I have always been impressed with their professional service and knowledgeable staff. ESA notified me of severe rusting problems with my townhouse’s 22-year-old gas furnace following annual inspection. With their help and advice, I chose a new Carrier furnace as a replacement. It was installed in mid-January by a very capable crew. Cody, Dylan and John M did the work on time, cleaned up afterwards and explained the new furnace’s features and operation. I am completely happy with the result and glad to recommend ESA to all concerned.”

“Wow! I see why they’re the best in Howard County. Richard ensured we received the best quality service. He was fully transparent about what was and was not needed. Alex did an outstanding job at figuring out what was wrong with the unit. Moreover, they did not leave until it was fixed. Honest, knowledgeable and reliable. I highly recommend their services!
Thanks again!”

“The weather had shifted and we were freezing. Our heat was not working. With limited availability due to work, I was hoping to be seen asap. They had a cancellation, and fit me right into their schedule. The service technician was friendly, professional and fixed the problem in minutes. I appreciate their honesty and excellent service. I will forever be a customer and highly recommend ESA.”

“Hello. A big thank you and shout out to Scott, April and Alex for their help this week! I appreciate the time that Scott took to speak with me on the phone about the switch on the air handler and how the plastic covering gets dirty. It was great that April was able to schedule a technician to come out so quickly. And, Alex thoroughly investigated, cleaned the plastic covering and took photos to show that there wasn’t dirt/mold in other parts of the unit. Thanks again for the prompt and professional service.”

“Best HVAC service I've ever had. Been with you for many years. Shane was the best of the best. Very thorough with his review of the AC. Took his time to do that. Taking time to do a very good job is most important to a customer. Hang onto that guy!”

“Environmental Systems has proven their commitment to customer satisfaction. As soon as the management learned of my period of unsatisfactory dealings with them, they reached out immediately to rectify the situation. Their concern and commitment renewed my long-standing trust in their company. My 50 year sole reliance on them for all heating and air conditioning service has been validated by their superior handling of this problem. And I will continue to give them a 5 star rating.”

“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.”
