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.

"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."
