The wired-in generator was the best renovation I did when renovating this house. I have been dealing with Mountain Generator Services for approximately 15 years. Darrin calls annually to see if I would like service on my generator, we don’t need an appointment as it is outside and he can come when he’s in the area, he then sends an invoice in the mail. Darrin looks after the generator very well, his fees are reasonable, and he’s very reliable, knowledgeable, and personable.
