Generator Installation
Whole-home and commercial standby generator installation, hookup, and maintenance for Southeast Wisconsin.
Why You Need This Service
Wisconsin weather is unpredictable — ice storms, severe thunderstorms, and heavy snowfall can knock out power for hours or even days. A standby generator automatically kicks in within seconds of a power outage, keeping your heat running, refrigerator cold, sump pump active, and medical equipment powered. For businesses, downtime means lost revenue. A properly installed generator eliminates that risk entirely.
What's Included
Typical Project Scope
A typical whole-home generator installation takes 1-2 days. We start with a site assessment to determine the right generator size based on your home's electrical load, fuel source availability, and placement options. We handle everything from the concrete pad to the electrical connections, transfer switch, and fuel line. Every installation includes full testing under simulated outage conditions and a walkthrough so you understand how your system works.
Our Process
Load Assessment
We calculate your home's electrical load to recommend the right generator size — typically 22kW to 26kW for most homes, larger for homes with electric heat or EV chargers.
Site Planning
We identify the optimal placement considering setback requirements, fuel source proximity, noise considerations, and service access.
Permits & Utility Coordination
We pull all required electrical and gas permits and coordinate with your utility for the interconnection.
Installation
Concrete pad, generator placement, automatic transfer switch, fuel line connection, and full electrical integration — typically completed in 1-2 days.
Testing & Training
We simulate a power outage to verify automatic start, transfer, and full-load operation. We walk you through maintenance schedules and operation.
Frequently Asked Questions
How much does a whole-home generator cost in Wisconsin?
A typical Generac whole-home standby generator installed costs $8,000 to $15,000 depending on size (22kW-26kW), fuel type, and site conditions. This includes the generator, transfer switch, installation labor, concrete pad, and permits.
How long does generator installation take?
Most residential generator installations take 1-2 days once the equipment arrives. Lead time for equipment ordering is typically 2-4 weeks.
Do I need a permit for a generator in Wisconsin?
Yes. Wisconsin requires both an electrical permit for the transfer switch and wiring, and often a gas permit for the fuel line connection. We handle all permitting as part of the installation.
How often does a standby generator need maintenance?
Standby generators should be professionally serviced annually — oil change, air filter, spark plugs, battery check, and transfer switch testing. Most units self-exercise weekly to stay ready.
