"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."

"Our existing generator died. James diagnosed the problem and gave us a few options to repair or replace it. We chose to replace it. James handled everything, from getting and installing the new generator to electrical and fuel (propane) connections. We have asked him to schedule us for the annual maintenance on the machine. We are pleased, though we haven't lost power since it was installed, LOL."

"People are very nice and honest.. Did the work on time and did a good job. I did not like the thermostat that was installed. We are older and could not read the actual temp because it was such small print. It was also very hard to program. They installed the new one and took the time to show me how to use it, at no extra cost. Very happy with their work."

"I gave an A rating, despite some bumps on the scheduling. The A rating was earned by Danny and the work he did to get the various new light fixtures installed, both inside and outside. We have more fixtures to be installed, and we will have Danny back to finish the job."

Generator Install questions, answered by experts

For generator installation in MD, choose a reinforced concrete base with a gravel layer for drainage, which helps prevent shifting during wet seasons. Use THWN-2 copper wiring in PVC or rigid metal conduit for safe electrical connections. Black iron pipe or CSST is ideal for natural gas lines, while DOT-approved connectors suit propane. Weather-resistant enclosures and stainless steel fasteners protect against MD’s variable climate.

Helpful?

In Hagerstown, generator maintenance should include running the unit under load each month, changing oil every 100-200 hours or annually, and replacing air filters and spark plugs yearly. Check battery terminals quarterly, especially after harsh winters, and inspect fuel lines for leaks or wear. After heavy storms, clear debris from vents and ensure the transfer switch operates smoothly to keep your backup power reliable.

Helpful?

In Hagerstown, the generator’s concrete pad may shift due to freeze-thaw cycles, so monitor for cracks or settling. Electrical panel connections and gas line fittings can loosen with seasonal changes. Pay attention to ventilation areas, keeping them clear of leaves or snow. Homes with well pumps, sump pumps, or older HVAC systems often need extra attention to ensure consistent backup power during outages.

Helpful?

In Hagerstown, create a seasonal inspection plan by checking for freeze damage and clearing debris each spring, testing the generator and cooling system before summer storms, and inspecting seals, batteries, and block heaters in fall. During winter, keep the unit free of snow and run monthly test cycles. Year-round, monitor for leaks, fuel levels, and ensure the transfer switch is functioning properly.

Helpful?

In Hagerstown, consider generator installation if you experience frequent outages, depend on well water, or have medical equipment at home. Schedule installation before storm season or if your current generator is over 10 years old, struggles to start, or can’t support your home’s electrical needs. Upgrades are also wise after major renovations or if local weather patterns have become more severe.
