Customers say: Quality work
"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."

"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."

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!"
