In 1972, Mike Hendricks, Sr., set out to create his own business. Trained as an aeronautical engineer, Mike specialized in designing equipment involving airflow, pressures, vacuums and electronic controls. That experience with complex airflow systems transferred easily to the HVAC industry. Mike wanted to create a straightforward, honest business that would succeed on the basis of his own skills and integrity. Most of his early customers were friends and colleagues. In 1973, as his customer list grew, he left the corporate world to devote his full attention to the endeavor. In late 1973, he hired his first employee, Richard Dean, who was working his way through college at the University of Maryland. Over the next few years, Richard received his degree in information systems management, and they formed the partnership that is Environmental Systems Associates.

Over-Rated & Watch Your Wallet:



We chose Environmental Systems Associates to examine problems that we were having with our heating system because of their good reviews. Things started out well. Terrence, the technician who was sent to examine the problem, did a good job. He fixed a minor problem and noted that the motor module needed replacement. He told us that part would be “easy to get locally,” and during the subsequent visit, we would not be charged for a service call, but just for the time for installation.



The problem began when we received a call from Maureen the next morning. She indicated the motor module would cost us $ 530.54 and with installation the total cost would be $ 790.54. I was surprised by the high cost and mentioned that the motor module seemed like a small part. She laughed and told me that I did not understand, because it included a lot of complex computer parts. I then asked how long it took to install. She noted that it would be about an hour. When I asked why it would cost $ 260 to install, she indicated that it included the time to get the part which “was not easy.”



The combination of her condescending/negative tone and the inconsistency with the technician’s comment about the ease of getting the part resulted in our seeking other alternatives. Several other contractors provided costs for the job. The cost for the part was somewhat less expensive from the other contractors but only by about 10%. The cost for the labor for installation was much less expensive with the highest being $ 130. Therefore, Environmental Systems Associates cost for installation was 100% higher than the next highest estimate we received. When the technician from the contractor we chose installed the motor module, it took him ½ hour. He apologized for having to charge us $ 125 as they had to charge their minimal hourly fee.



We should probably thank Maureen for her attitude as it inspired us to call others and save a lot of money.

Steve P. came to help out us today when our furnace was not working. He was extremely professional, knowledgable, courteous, and quick. I could not have asked for better service!

We have used ESC for over 10 years and they have always done a most professional job from installation to regular service. We particularly like Tim L for his knowledge, and professionalism when at our home. He always goes the extra mile to insure all is well with our systems. This is a great company and we highly recommend them.

I am totally delighted with my new heating/cooling system provided by ESA.

Frank H. and his skilled team (Ryan, Bryant, and Mike) did an excellent job

today. They were completely engaged in seeing that everything was done

in a timely manner and the work was done correctly. I would highly recommend

Frank and his team to anyone whose interested in replacing an old system.

I have used Environmental Systems Associates for more than a decade now and consistently receive great service. Today, Paul G came and not only did the annual service to my air conditioner, but also fixed the problem we had with it -- it stopped working during the heat wave two days ago.



Paul likes his job so much that he was happy to work on his birthday! :-)
