"Mohammed handled our project—sealing and insulating our attic. He was very knowledgeable about the best way to accomplish the task in an older home such as ours; and he also ensured that our project qualified for relevant energy rebates. He was professional and courteous in answering all our questions and completed the project in one day. We highly recommend HESS and Mohammed El-Goul."

You and your family deserve to receive the best care and the best service. Not every heating & A/C company gives you the quality people and care that Presidential does. We offer 40 Years of Award-Winning Quality People, Quality Installation, and Quality Service. Delivering this quality service and care for your home is our commitment to you! Family-owned and operated, Presidential specializes in residential and light commercial service and installation throughout MD, VA & DC. Ask us about our system replacement specials and The Advantage Maintenance Plan for preferred VIP service. Presidential has been awarded the Carrier Factory Authorized Dealer Award and is a member of the ACCA (Air Conditioning Contractors of America) and the Quality One service network.
"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!"

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."

"I called to get an inspection done on my AC unit and was quoted $90 for the inspection plus $120 an hr for ADDITIONAL hrs. I ASKED when do I know when the “additional hrs start”, He stated that the tech would let me know once the inspection was done and then at that time he would let me know if there was work that needed to be fixed or if there was nothing then the service would end and I would only have to pay the $90. They charged me $210 for the inspection. I called and requested that we both listen to the call (Because all calls are recorded) They played the call, heard what the rep said and then stated they would get back to me. When I finally reached them again (they never called me back), they stated I would not get a refund, then replayed the call cutting out the part when the rep stated clearly that the service was only $90. They not only GASLIGHTED me, but they altered the recording. $120 may not matter to most but it sure matters to me."
