Get matched with top generator install pros in Derwood, MD

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

"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."

"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."

"We have been using Dave since we moved to Maryland nine years ago . He is knowledgeable, efficient, reasonable and friendly. That he is a master electrician says a great deal about his years of experience and knowledge in electrical work. I highly recommend him."

"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!"

"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"

"I had John and Aaron come to my home because I was interested in installing a Theater in my new home. They went through the new technologies and options for the Theater and were very knowledgeable. I ended up going with a 4K projector and a Dolby Atmos and absolutely love it and show it off to all my neighbors. Iâ m so glad I took their recommendation on spending the extra money on the projector to get true 4K. I watched the Pitt game this weekend in 4K and it was amazing. I totally recommend this company."
