"This is an excellent company. We have used them for year to service our heating and air conditioning units. It became necessary to think about replacing the units. We have two. Decided to replace both at the same time. They came out on a Monday and gave us an estimate and came out on Thursday and Friday to do the work. They totally cleaned up after themselves and made sure everything was working properly. Then they called a few days later to see that everything was working well. I highly recommend this company. All the technicians are polite and competent. The office staff is nice beyond belief. If you need any heating/AC work done, this is the company to do it."

"I signed up to have one of my HVAC's covered by Tim Kyle. I used the electrical service for over 20 years and the service is exemplary. This is the first time I used the HVAC service. I was impressed. It was a great job performed by a knowledgeable, pleasant tech who was available to answer any questions I had. Most important the HVAC was up and running before the 100 degree days to come later this week. Thanks guys"

"GAC services was able to come out for a same day trouble shooting appointment. Jim S arrived on time and was very courteous and professional. He was able to quickly identify the problem with the registers and dampers and able to get warm air flowing to the otherwise very cold areas of the house. In addition, Jim was able to recommend some additional services that would help me achieve the desired evenness of temperature such as an additional return and humidifier for the home. Great experienced master certified technician!"

"I am extremely pleased with EVERY aspect of using this company! Wes and his crew were knowledgable, professional and friendly. They worked efficiently and the price of my heating/AC system was the least expensive based on the three quotes I got. The job was done is just a few hours (and moved up a day on their schedule) so that i was able to have my condo's heat restored before the "polar vortex" blast of cold weather descended upon Maryland! THANKS WES!!!!!! I wholeheartedly recommend GLM."

"Dave the Tech was great. He called ahead to let me know he would be here in about 15 minutes and he arrived in the 15 minutes. He was courtesy and helpful and checked the unit inside and out. He explained every thing he was doing and what he found and how it could be fixed. Dave even took the time to talk to my husband over the phone on the issues he was finding. It was quite clear that Dave knew his stuff. I highly recommend Beltway Air Conditioning and Heating, LLC. I am definitely keeping their number by my phone."
