Get matched with top generator install pros in Darnestown, MD

"Long Electric recently completed installation of a whole house generator for our residence. The experience went very smoothly and they showed professionalism in every respect. We were especially impressed by their responsiveness whenever we had any questions about the procedure, as well as the extremely detailed proposal they provided. In the week since the completion of installation, we have already had a 2.5 hour power outage--and the generator worked like a charm. Overall, a great and painless experience. Highly recommend."

"Green’s Electric was great! They quickly provided an accurate estimate for the work we needed done. We appreciate the attention to details on the professional appearance of the work as well as the reasonable pricing. The finished work looks better than we could have imagined. Green’s was able to schedule the work very quickly and was on time and finished within the original estimated timeframe. I’d recommend this company for quality, reasonably priced master certified electrical work. They were great!"

"Oupekkha showed up exactly on time, explained clearly what he was doing, what his annual service contract included and reassured me that our generator is good to go. He even topped off the oil for us. I signed up!"

"David was great to work with! So diligent to ensure that everything was installed properly and walking me through the calibration. I’ll definitely call him again for electrical work."

"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."

"He found an electrical problem that Potomac Edison arrived to do a emergency repair. It was a fire hazard. So thankful he found the problem and did an excellent install with our Generator."

"On both appointments, the technicians (David the first time, Matt & Evan the second time) were respectful and honest, very well organized. And they arrived right on time. We had ceiling fans and recessed lighting installed. They kept the work areas clean. -Frank K., City of Gambrills. My wife and I are very happy with their work, and the jobs were completed in the quoted time, even early! Everything was well explained and questions were answered with the feeling that they weren't in a rush to leave until I was satisfied. We will call again for future jobs."

"Very friendly from the technician to the secretary. They got me in fast worked with my schedule and got out fast. They also mounted my ring doorbell.. Excellent service and the price was awesome"
