"I highly recommend DES! I arranged a consultation after a home inspection report indicated that there was moisture in our basement walls. I was worried that costly mitigation efforts would be required. A friend who had previously used DES for a basement water problem highly recommend them, telling us that they were an honest company that only does what is necessary to solve a problem. Happily, Mark Fine from DES inspected both our basement and our exterior grounds and reported that there was no indication of cracks in the foundation or water intrusion, and that no work needed to be done. It is so refreshing to have a company that doesn't try to sell expensive services when they are not necessary!"

Glenmont Heating & A/C
Glenmont Heating & A/C
When Glenmont Heating & Air Conditioning was founded 28 years ago, we had one goal in mind; providing area families, and businesses with solutions that fit their lifestyles and needs, as well as their wallets. If you have any questions about heating and air conditioning maintenance, a new HVAC system, or are looking into installing a more energy efficient system, Glenmont Heating and Air is the solution to your needs.
"Not Recommended for Thermostat Replacement — Unreasonable and Unfair $700 Charge I do not recommend Glenmont Air Conditioning & Heating for thermostat replacement work. I was charged $700 for a simple thermostat replacement, which I believe was unreasonably high and unfair. I was under the impression that the quoted estimate represented the maximum expected cost only if the technician had to perform additional wiring or complex installation work. If you want to install an Ecobee or any other type of thermostat, you can simply YouTube the installation, which provides step-by-step instructions on how to unwire, label, and rewire to the new thermostat. For my installation, I was under the impression that additional wiring might be needed, but it turned out to be a straightforward swap of the old thermostat with a new Ecobee unit, a process that took only about 15 minutes. Despite that, I was still charged the full amount. The Ecobee Premium thermostat itself costs around $250, meaning they charged nearly $500 just for labor, regardless of how simple or quick the installation is. To make matters worse, the installation only comes with a 30-day warranty, which hardly justifies such a high price. I tried to communicate and explain that this charge was unreasonably high and unfair, but they simply said, “It is what it is.” If you’re considering a thermostat installation, I strongly suggest hiring a professional through Thumbtack, where qualified experts can do the same job for under $150 with transparent pricing and good service. I expected fairness, honesty, and reasonable pricing from Glenmont, but unfortunately, that was not my experience."
