Generator Maintenance
A standby generator only earns its keep if it starts when the power goes out. Preventative maintenance keeps yours ready for the moment that matters.
Why does a standby generator need regular maintenance?
Peace of Mind Between Outages
The worst time to learn your generator has a dead battery is during a winter outage. Maintenance exists to make sure that never happens — it's the difference between a system that's technically installed and one that's genuinely ready.
We inspect, test, and service standby systems so the parts that fail quietly — batteries, fuel connections, transfer switches — are caught on our schedule, not the weather's.
What Maintenance Includes
A thorough service goes through the parts of a standby system that need attention to stay reliable.
Visual inspection
Checking the unit, enclosure, connections, and mounting for wear or damage.
Battery check
Testing the battery and charging system — a leading cause of no-start failures.
Fluid & filter review
Inspecting oil, filters, and other consumables that keep the engine healthy.
Fuel system check
Confirming the propane or natural gas supply and connections are sound.
Transfer switch test
Verifying the automatic transfer switch operates and moves the home correctly.
Load test
Running the system to confirm it starts and carries load the way it should.
Maintenance for Northern Wisconsin
Backup power here has to account for hard winters, rural properties and long distances between neighbors. It shapes how we plan every system.
Ready before winter
The best time to find a problem is before the storm season, not during it. Seasonal maintenance means your system is ready when Northern Wisconsin weather turns.
Cold is hard on batteries
A weak battery may start a generator in July and fail in January. Regular battery testing is one of the most valuable parts of maintenance here.
Any brand welcome
We maintain existing standby systems from a range of manufacturers, including units we didn't originally install.

Frequently Asked Questions
Straight answers to what homeowners and businesses ask us most.
A standby generator sits idle most of the time and then has to perform on demand during an outage. Regular maintenance — inspecting the unit, testing the battery, checking fluids and fuel, and running it under load — is what keeps it ready for that moment. Batteries and fuel-system issues are common failure points that maintenance catches early.
Standby systems benefit from regular, scheduled service and periodic self-test cycles. The right interval depends on the system and how it's used. Seasonal service before winter is especially valuable in Northern Wisconsin.
Yes. We provide maintenance for existing standby generators from a range of manufacturers, regardless of who originally installed them.
Battery and charging issues are among the most common — a weak battery is a leading cause of a generator failing to start when an outage hits. Regular testing catches it before it leaves you in the dark.
