"It was very easy to schedule an appointment. I called on 11/9 and was able to schedule an appointment for 11/10 between 11:00 a.m. and 1:00 p.m. The plumber arrived early. He said that I needed a new faucet. I went to Home Depot and purchased a new faucet. I called Ehrhardt after I had purchased the faucet. A plumber came to my house about 30 minutes later to install the new faucet."

"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."
