How do I know if I need to upgrade my whole house generator?
Several signs point to upgrade time. Your unit may need frequent repairs. It might fail to power all essential circuits. Generators over 15 years old often need replacement. Added appliances like central air or EV chargers increase your load. Your current generator may not handle these demands anymore. We perform load calculations to confirm if you need an upgrade.
Most homes need between 16kW and 22kW. Size depends on your square footage and electrical demands. We calculate total load by examining your main panel amperage. Most homes have 200-amp panels. We identify your essential circuits. Homes with electric heat or well pumps need larger units. Motors create startup surges that require extra capacity.
Most upgrades take two to three days after permit approval. Day one involves removing your old unit. We prepare the pad and connections. Day two covers new generator installation and transfer switch replacement. We test all circuits afterward. We schedule the required municipal inspection. Then we complete final startup and programming.
Usually yes. Older transfer switches may not work with modern generators. New generators use digital controllers. New automatic transfer switches respond faster to outages. They provide better surge protection. We install 200-amp rated switches. These monitor utility power constantly. They switch to generator power within ten seconds of detecting failure.
Yes, we can. We install the concrete pad first. We run natural gas or propane fuel lines. We wire a new automatic transfer switch to your main panel. This eliminates manual cord connections. You get instant power during outages. The upgrade requires electrical permits. We coordinate with utility companies for gas line installation and meter modifications.

Standard policies don’t cover elective upgrades. Many insurers offer discounts for whole house generators though. Generators prevent damage from extended outages. Some policies cover partial costs if upgrading due to storm damage. You need documentation for claims or discount applications. We provide detailed invoices and all necessary paperwork for your insurance company.
