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.” – Helen M.

100% agree with the outrageous prices. Had a technician come out for a system check-up. We have two units. It costs $129 for each unit. This DOES NOT include filter replacement. We found that out after the fact. The technician replaced 2 filters and a humidifier panel ($20 on Amazon that they charged me nearly $50.)Total Bill? $458 just to tell me everything is working fine and to change 2 filters. NEVER AGAIN.Response to Owner reply:We were aware if the $129 per unit charge as was told to us when we scheduled the visit. We were NOT made aware that the filters were not included. If the filters we had weren't included in the scheduled service that should have been disclosed.Your prices are still incredibly expensive. It's a niche service and you are free to charge what you want, but I feel as a customer I should let other future customers know what they are getting into when they seek your services.

Salesman Richard was prompt in answering my questions and very clear in describing his product. I had a new gas line installed from the street to my house by BGE. ESA kept me informed as the project progressed. HVAC system was done according to stated schedule. Installer Ryan fully explained the install, and he and his crew were very efficient and left site in good order. I have no hesitation in recommending this company.

I can't say enough about how pleased I am with Environmental Systems Assoc. (ESA) I was in the market for replacement of two full heating and A/C systems, and requested quotes from several contractors including ESA. I was initially attracted to them by their many years of "Best in Howard County" rating as well as the ESA website. By far, ESA was the most responsive and prompt in reviewing my systems and providing a quick quotation. The quotation was the most professional and complete, with a high level of transparency on what was being quoted and a competitive price. They patiently answered all my questions, they were willing to work with me on specific requests I had, were able to schedule the work in a reasonable timeframe, and were able to install both systems on the same day with minimal disruption.The installation crew was also excellent. They knew what they were doing, were professional and polite, they laid tarps down wherever they needed to be, and left the house and premises in a clean state. They also did a great job of educating me on the operation of the new system and thermostat programming, providing all the equipment manuals and warranty information, etc.It is very clear that ESA has a strong customer focus, an excellent product portfolio, excellent support information, excellent service and installation capability.

We had the entire HVAC system, including a new hot water heater installed recently. It was a big job and the crew who got the job done in a timely, professional and clean manner. I was instructed on how to use the new system. Thank you.

This ESA team removed our old heating and a/c system and installed a new one. They came on a Saturday morning and were done in two hours, working as a well trained team. They were efficient, courteous, and informative and left the work areas spotless. Thanks for leaving us prepared for a hot summer. Highly recommend Environmental Systems Associates.

There is a good reason why ESA is in demand. Letting just anyone mess with your HVAC can be a disaster, an expensive one- and an expensive lesson I learned.These guys are good at their work, and not out to rip you off. It can feel daunting as the most of us are not HVAC experts. I felt like I was getting professional advice with sensible and relatively affordable options.Highly reccomend, they have a lifetime customer now.

Mr. Hendricks was amazing - he was able to quickly get back to us after our AC died and found a heat pump system for us in stock at a reduced price. The installation team (Dennis, Seth, Skyler, and John) was friendly, professional, and did a great job. We have a 2 month old and our AC broke - we were afraid we were going to have to wait a long time to find an AC in stock. Thank you so much.
