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.

Summary: Company charged me $1000+ for 2 separate service visits that did not fix my AC unit; technicians and Operations Manager are not truthful about work done; Operatiins Mngr will tell you find another HVAC company when you express dissatisfaction ….I contacted Glenmont Heating and Air Conditioning since my AC unit was not dispensing any cold air. Thermometer was set to 68° however the unit temperature was reading 77-80° (note this was the week of extreme heat wave). On 21Jun2024: Glenmont technician Roderick performed a service call. I spoke to him via phone after the call to which he told me he added refrigerant to the system. This did not fix the issue and the unit continued to not dispense cold air with the thermometer reaching 77-80° despite being set to 68°. I was charged $119 for this work. Operating Manager Tim Schindle is contradicting what the tech said and claims Roderick did not add any refrigerant. I again called Glenmont HVAC for a second service appointment. This technician claimed the coil needed to be cleaned. The second technician (Eric) then falsely reported on his report the unit temperature dropped to 68° when he left when I have photographic evidence showing the temperature in the high 70s. I waited about 24hrs as instructed for the thermostat to drop and it never did and the unit continued to not dispense cool air. I then called a supervisor (don’t recall name) who essentially told me due to the extreme temperatures everyone was experiencing HVAC issues and did not recommend any follow up service. I then had several back/forth emails with Operations manger Tim Schindler to notify him after 2 separate service visits, my air conditioning was not fixed. In the end he told me, and I quote “my system is old…we don’t know the maintenance history…it is best for both of us to find another HVAC company. He did however bill me $964 for the second service visit, which did not fix my issue. I ended up having to call another HVAC company who diagnosed the problem as a compression failure/ replaced the unit and now have cold air blowing. The second HVAC company did not understand why the 2nd technician from Glenmont Heating/Air Conditioning was changing coils and said this was not necessary to do. Second HVAC company showed me the reading of the compressor unit to which I could see no charge was registering, essentially the compressor was no longer working which was the root cause of my issue. In conclusion, I’m disappointed with Glenmont HVAC and feel they sent incompetent technicians who falsified their work. When I complained to the company and expressed my disappointment with their work (or lack there of) they told me to seek other HVAC company without fixing my AC unit but charged me $1000+. Poor business acumen and highly unethical company that needs to be held accountable for cheating customers and not performing quality work.

This company was amazing. They were on time, honest, efficient, and did good work. I would definitely trust them and use them again.

Glenmont Heating and A/C was fantastic. It's so hard to get good service these days. But, when you do, it's a great feeling. Kyle was professional and helpful. We had never used Glenmont before but they had a great rating on Angie's List so we called them. I would recommend them in a second!!

Two projects. Heater motherboard went out and was replaced...couple months later blower motor went out. Nothing was done same day but taken care of within a few days...older unit and parts ordered. Very professional and well trained staff.

Came out and replaced in 5 hours the day after they provided estimate during very cold period

They do a Fall maintenance and a Spring maintenance. We have a yearly service plan, so it was covered under the service plan. We've been using them for a lot of years, approximately eight years. I think when they come out and they do the work, they do a good job and I don't have to keep calling them back. They do what they say they're gonna do and they have good service plans so you can choose what would work best for you.

Technician was knowledgeable and diligent in performing work. Explained what the issue was, quoted the price before work began, timely finished the work.

They do a fine job, and have a very attentive back office.

The estimators showed up on time and did a thorough survey of the work needed to be completed offering suggestions on best to lay out the basement duct work. The installers showed up on time and completed the work the same day. The regularly asked me to make sure they were laying the duct works out in locations I wanted and in one instance came up with an idea that made the ducts less obtrusive in my plans for remodeling the basement. Both workers very friendly and efficient in their work.

They arrived on time and with all they needed.  Laid out a floor covering each day, cleaned up at the end of each day, were polite, professional and knowledgeable.  It was a lot of work, more than they anticipated but they never asked or even suggested that the bid price was a problem.  They ran into more problems than they anticipated and wanted to adjust the schedule by a week...when I said that would not work for us, they adjusted their schedule to meet our needs. They kept the hot water on the whole time even though it was a royal pain for them to do so.
Greg was the office man and was great.  Billy did the on the job supervision and all the work and he was terrific. 
I'd use them again in a New York minute!
