I Went to a demonstration put on by Reliant. They showed how a 20kw Kohler was actually better than a 22kw Generac. Mike Bell was great at following up with me. Yvonne Fish answered any other questions I might have had. Installation was set around my schedule and was convenient. They cleaned up after themselves, No problems. No hassles. All went extremely smoothly! Couldn't have asked for a better experience.
