Install a year and a half ago went without a hitch. Grasten obtained all permits and was present for each phase. Their technician, Jordan, was on time, professional and answered questions I had without hesitation. We haven't had any problems, but based on what Grasten has done so far, I don't doubt they would stand by the product (General Whole House Generator). ~ Rick Pattison, 04/08/2017
