How much does whole house generator installation typically cost?
Whole-house generator installation cost varies by home and electrical setup. A Wisler electrician will confirm exact pricing after an on-site assessment and provide a fixed quote. Costs depend on whole-home capacity and required electrical tie-ins, such as the automatic transfer switch (ATS) and any panel coordination. We offer a free quote in the Roanoke area and financing options (GoodLeap). Current promo: $500 off installation of a Kohler whole home generator plus a free 200-amp ATS with qualifying purchase.
