"They installed the 25 KW Generac generator efficiently, upgrading the gas line from the gas main to accommodate the additional load and installing the generator on a concrete slab they poured. The generator supports my entire house including 2 AC units and all appliances except the kitchen range--just what I wanted. The unit is quiet and esthetically placed. They trained me in caring for it so that I know how it works. They instilled sufficient confidence in their expertise that I keep a maintenance agreement with them, so that they inspect it and give me confidence that it will kick in whenever needed. They know what they are doing and are a joy to work with. Even their admin staff are professional and very helpful on the phone. They get my highest rating." Robert
