Returned initial call the same day, owner visited 8am the following day. Full inspection of home and positive recommendation. Chosen as he was a Premier Rated installer by Kohler. Installed in 2 weeks, town electrical inspector stated it was the best job he as seen. Installed in 4 hours. Great clean up. Great follow up. Fully reviewed functioning after installation. Kept me advised in licensing process with the township. A great generator, quality installation, great guarantee. Highly recommended. One of the few contractors where the owner, who helped with install, provides his cell phone number. – Dennis, Easton, PA
