Get matched with top generator install pros in Arnold, MD

"Installation went well. They were patient with me as I explained exactly what it was I needed. After the installation, the fan vibrated very loudly into my bedroom. I called to have this fixed, and the work was done in a few days with no additional charge. The fan has been working well."

"Keith and the team did a great job (quick and efficient) in relocating my electrical panel and also installing my EV charger. Great work. Highly recommend."

"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."

"Outstanding! Super professional. Offered advice on my electrical installation and did the work quickly. I was very pleased with the end installation."

"Mark kept us informed and showed up when he said he would. He installed about 2 dozen light fixtures, fixed a couple outlets, and added outlets all in the time it would have taken me to do just one. He was fast, efficient, and left no sign behind that he was even there. For any work in the Annapolis area, I would highly recommend him and will definitely call on him in the future for my electrical needs. He pricing was beyond fair for all of the work he did from the lights in the attic, garage, living room and crawl space."

"Your technician that came out to do a yearly maintenance inspection on my generator was very nice and knowledgeable. He arrived actually earlier than expected and went right to work. I would recommend your company to anyone and it was so nice to deal with someone who acted like they enjoyed their work and wanted to please. Thank you!"

"Mr. Electric responded immediately to my request and scheduled the quote visit the next day. They were able to fix the electrical switch during that apointment in a very fast and professional manner. I highly recommend them."
