"The technicians that came out were very professional and knowledgeable. They installed a complete heat pump system and did not leave until I was completely satisfied. The original thermostat that came with the system did not work, so installed a temporary thermostat and order a new one. It was installed the next day. All techs that came to my home were very professional and knowledgeable, the service was great"

"I’m back again to write another stellar review for GAC. Last year they replaced our HVAC system; this year we circled back and had them install a home generator. This was a long and drawn out process due to the various approvals needed from Montgomery County as well as coordination with Washington Gas (which ended up not just being a simple sign off but necessitating an additional, expensive upgrade to the gas line from the street to our home). Nevertheless, GAC did a fantastic job shepherding this process over the 6+ months of waiting on stakeholders, and they were also maximally accommodating to our family’s significant constraints on time and availability (due to health concerns related to a medically fragile family member). A special kudos to Sandy M, GAC’s master electrician, who took it on personally to ensure we were taken care of all throughout this process, going above and beyond with phone calls, text messages, personal visits, etc. on behalf of my family, I want to thank GAC and am giving top marks across the board for this effort which was complex , lengthy, and ultimately successful."

"Carlos was great, he explained everything in terms I could understand! I had to have another company come out last year because A/C went out, they were ok. I will always come back to McCrea! McCrea has been the company that my family has been with for at least 30 years!"

"Adam was so helpful explaining how the ductless heater/ac unit would fit in my sunroom. His three workers were great. Cleaned up the area after they finished, the job was done in about 4 hours. Got three estimates and Weather Masters was the lowest and could install the next day. I also decided to sign a contract for seasonal checkups on my furnace and central air conditioner. I think anyone would feel comfortable hiring them."

"It went perfectly. Randell was professional and my installers Walter and Eddy were the best. Would recommend company highly."
