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.”

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.”

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.

All three men and their helpers did an excellent job. Worked from the time they arrived until the job was finished. Coordinated the installation of the new heat pump on the roof with the installation of the new heating and A/C unit in our condo unit. Also they responded quickly to make an adjustment for a minor problem, which was then resolved.

After using Environmental Services for over 40 years, I have to comment that in the last 6month I have found their service to be totally unacceptable.They have refused to honor my prepayment for last years service agreement. Each time I have called, a receptionist says I need to speak with the service manager, Steve. She always says he is "out of the office" and connects me to his phone message line. He has never returned my 3or 4 messages. I have been a paying customer to them since early 1970's. What happened to loyalty - something has changed in their business model. I am finding a new company.

We have been using Environmental Services for 30 years. Tonight, 3/7/22 I called because our Vice thermostat was not working properly. ESA put it in 9 months ago. Later with a winter checkup we complained about this thermostat and they were supposed to put in a different one. The technician did not bring one. Today, I called after hours and tI explained that all I wanted to do is find out how to turn off the system because it keeps running and running. The operator said she will take the message and someone will call in the morning. Yet, the recording says if it is an emergency press o. I don’t think that is the way to handle an emergency if your system won’t shut off. All I am asking is for someone to call back and guide me on how to use this confusing VIVE thermostat. In the past a person has called back and helped me over the phone. ESA’s service has deteriorated in the last couple of years. Like I sad we have been loyal customers for 30 years. Plus the fact their more recent payment structure for service contracts is lousy.
