"Excellent service! I had a 26yr old A/C and Propane furnace that I wanted to update to an ALL ELECTRIC high efficiency heat pump. The price in the estimate was much higher than I was expecting, but they worked with me and brought it down considerably, provided I could accept an install slot in a couple of days due to a cancellation. Go for it, I thought! Unfortunately, it turned out that the estimator/salesman (who shall remain nameless) apparently got a bit confused and set up the equipment as a hybrid propane system - not the all-electric system that I wanted. Ugh. I only realized this when the installers had the indoor unit in place, and I saw the propane burners. Doh! So, I explained the situation to them, and they pulled the unwanted unit out and jumped through the hoops to order the correct unit and its accessories (wiring, breakers etc.), with no change to the price. They were very friendly and polite through all of this even though it meant the wasted work and that they had to come back the next day with the new IDU. Anyway, the final install all went well, and they were very friendly and respectful of the property and explained all the install details as they went (sorry Melvin, for all the pestering!) I'm very happy with the company and the installer's knowledge and professionalism. RECOMMENDED!"

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."

Terry Home Repairs
Terry Home Repairs
Support a local minority-owned family business and hire me for any heating, cooling, electrical, or plumbing needs. I guarantee fair pricing, and honest hard work. I have over 20 years of experience in the field in both commercial and residential work. I am a certified HVAC Technician, and have worked as a Building Engineer with some of the top building management companies (Cushman and Wakefield, CBRE). I also worked with George Washington University as an Appliance Technician, the Port of New Orleans as a Plumber/Pipefitter, and with Norwegian Cruise Lines as a Marine Engineer/Motorman. If I can keep a ship floating, I can fix any home repairs you need! I specialize in heating and A/C repairs, but I'm starting out my business and looking for any opportunities to grow my customer network - able and happy to do other home repair jobs like welding, painting, mounting, snow or leaf removal, gutters, decks, drainage, and more! I even just mouse-proofed my house by installing a ridge vent guard and garage seal, and I could help you solve any pest problems too!
"Everyone needs a little Terry's Home Repairs in their life. Our oven digital display snapped off and fell through the opening. I talked to an appliance contractor [before finding Terry's Home Repairs] and he indicated that the whole control board would need to be replaced (at a cost of $430). When I asked him if he could provide a refurbished control board or if he can just resecure the existing display back to the opening, his response was "modifications" is not something he would be willing to do. At this point I began doing some research. I located Mr. Terry on Angi's List and after reading reviews and discussing the problem with him over the phone I decided to move forward. He provided an exact time he would be at the home and showed up right on time (on a separate but related note, I am really sick and tired of the 'four hour window' provided by the larger contractors - I am busy as h*** and do not have time to block off four hours of my day). Upon arrival, Mr. Terry identified the issue and provided a new bracket to secure the oven display. While there, he also fixed the exhaust fan (over the range) and also fixed a dryer vent that was coming apart. His price was fair and his work was good. I will be using him moving forward for 'odds and ends' and random things around the home. I like his background (he worked as a mechanic on a cruise ship and also worked in Alaska on HVAC related projects)."
