"Danny treated me like an old friend with helpful and timely service. It was refreshing. He inspected the unit, found a failed capacitor caused by an add-on Michael and Sons installed last inspection. Danny replaced the failed part, removed the add-on, and I was back in business in less than 30 minutes. I have a new HVAC provider!"

"THIS COMPANY EMPLOYS EXTREMELY TRUSTWORTHY EMPLOYEES THAT ARE A PLEASURE TO HAVE IN YOUR HOME. THE CARPENTER WE HIRED AT THE SAME TIME WAS SO IMPRESSED WITH THEIR WORK AND KNOWLEDGE, THAT HE HAS USED HIM ON OTHER JOBS HE HAS BEEN HIRED TO DO. THEY ALWAYS CLEANED UP AFTER THEIR WORK, THEY WERE COURTEOUS AND RESPECTFUL OF OUR HOME AND FAMILY, AND WERE VERY PUNCTUAL. SINCE THEY HAVE INSTALLED OUR SYSTEM, WE HAVE NOT HAD PROBLEMS OTHER THAT 'USER PROBLEMS' (I.E., NOT CHANGING FILTERS FREQUENTLY ENOUGH). HOWEVER, WHEN WE DO CREATE OUR OWN PROBLEMS, THEY HAVE RESPONDED VERY QUICKLY TO OUR NEEDS AND THEIR PRICES ARE VERY REASONABLE. I WOULD RECOMMEND THEM TO ANY FRIEND OR NEIGHBOR."

"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."

"I had a leak somewhere in my heat pump system from 2013 in a 4 floor condo building. Every other company was quoting me $7k+ to replace the system but it turns out to be a leak in the line set between the 3rd floor and the roof! We had a new line set installed and I spent $2550 in total! The crew was very professional and worked extremely had in the hottest weather to get the job done, too!"

"The technician was great, thoroughly took his time figuring out what would be needed to complete the job."
