"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."

"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!"
