Nice reliable prompt guy. Was not happy that the $95 per hour on the quote is just a call-out fee. So actual cost was more, but Jason assured me it was in line with others. He had in fact been to us previously and replaced the battery, which he had to replace and charge for again. He said it is a common problem with Generac generators. All in all I believe he is a generator expert, but I think his online quotes should specify his charges more clearly.
