"Mr. James Rollins was exceptional. Had an issue that came up last year with my Generac generator and he was quick to respond but I was not able to be as fast. Power came back on so I didn't follow up. Generator hasn't worked and was worried about a power outage, so I reached back out. He came out on the same day, diagnosed my issue in a minute, and fixed it. His work was outstanding and I can understand why he is so busy. Everyone wants Rollins Repair. If you can get him, I would ask James Rollins to help you."

"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!"

"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."

"Ron Ethridge (owner) did the work. He was friendly, helpful, knowledgeable, and experienced. He was available on the phone during the project - after hours and weekends. He is very familiar with permitting and licensing and working with Pepco and the inspectors."
