"L I put request on Home advisor/Angie's list. Out of all the request this is the only company that responded to my request. Not only did he respond within 30 minutes, he came out the same day, installed my ceiling fan, and finished everything up within one hour. Most kind efficient, professional, and very knowledgeable company. I would definitely use them anytime and every time. Thank you so much, Kevin."

"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."

"He gave me a fair price to install an EV charger for my car, communicated with me to make sure it was installed correctly, and was even able to move some preexisting equipment around to make room for the charger."

"Things went well. Russ Piper came out and met with me - to see what the project entailed. Meeting went well, I fully understood what they were going to do. I got a quote back quickly and moved forward with it. When the plumber (Plumb Crazy)came out to see what needed to be done, I had some options . I decided to have a higher service line brought into the home - now BGE is involved. Without further stories - it took many weeks to get BGE to install the higher service, Throughout, this process, Benfield and the plumber where checking in with me for progress. And when the inspections where all complete - they came right out and finished the installation."
