“Haller installed our generator about 5 years ago and we needed a service call. The Haller technician promptly diagnosed the generator service needed, had the necessary parts in his truck, and had the generator back in working order in what I thought was a short time. His knowledge and professional expertise were so apparent. I hope Haller Enterprises appreciates their techs as much as I do.”

“Thor Keck, Electrician for Haller Enterprise installed an interlock kit and circuit breaker for a back up generator for my home. The job entailed replacing some circuit breakers and moving a few other breakers to make room for the generator breaker; also adding the conduit/wiring to the generator inlet box. Thor was very professional and detailed oriented to make sure the job was completed correctly and in accordance with the NEC. I’m completely satisfied with his work, Thank You!”
