"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!"

"Excellent service"

"I highly recommend this company. They were professional, very courteous and very responsive to questions and concerns. They installed 2 BB filters and a UV purifier, and the workmanship is impressive."

"Tried to schedule a routine maintenance appointment available to customers who signed up for service plans, but Len could not follow through with their commitment three failed/rescheduled appointments in a row!! Each required four hour commitments from the customer. I tried to communicate with dispatch and customer service but unfortunately I don’t think these two departments have an open line of communication between them. I would not recommend for anyone to work with or engage with this company. Len did not follow through on their half of the commitment and disrespected my time as an in office working professional."

"Great fast and professional"

"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."

"I have used Grove for many years, and even had them replace on of my failing units. Within the past 18 months, our secondary unit started having problems and Grove came out multiple times to service the unit, explaining that it was losing refrigerant and needed to be replaced. They were always very quick to provide an estimate to replace the unit after charging it. Before replacing the unit we had a different vendor come to give a second opinion, to ensure we were informed and I am so happy that we did. We found that the unit wasn’t only running out of refrigerant, but that it was massively overcharged and that the overpressure safeties had been defeated. I’m not sure if Grove was simply negligent or if they were trying to trick us into paying for a replacement, but I can say that I won’t be using them again. The unit they replaced for us is already dead, and they are quoting us an additional $2k to repair it, putting the total cost for the unit at nearly $10k. All said I have probably paid Grove thousands of dollars and it’s impossible to tell what of that was legitimate and what of it was them running up the bill. I can tell you that at one point they made an emergency visit late at night, spent 15 minutes looking at, and cleaning my compressors, charged me $1000, and then proceeded to text me pictures of them on vacation, presumably enjoying spending the money I had paid them. While I really like Grove, I would suggest you get a second opinion regarding whatever they tell you and that you check your bill very thoroughly."

"perfect! Sterling did a terrific job!"

"They did a good job"

"I had a leak somewhere in my heat pump system from 2013 in a 4 floor condo building. Every other company was quoting me $7k+ to replace the system but it turns out to be a leak in the line set between the 3rd floor and the roof! We had a new line set installed and I spent $2550 in total! The crew was very professional and worked extremely had in the hottest weather to get the job done, too!"
