Spring is here, and so is Michigan’s unpredictable storm season. Before the next power outage catches you off guard, there’s one critical task every homeowner with a standby generator should schedule: a professional spring tune-up. At Wolverine Electrical Contracting, we see the same story every summer: a generator that sat idle all winter refuses to start when it’s needed most. Don’t let that be yours.
Why Spring Is the Right Time for Generator Maintenance
Standby generators are engineered to be reliable, but reliability doesn’t happen on its own; it requires consistent upkeep. After months of cold temperatures, condensation, and inactivity, internal components can degrade in ways that aren’t visible until a load is applied. Scheduling your generator maintenance in the spring means your unit is fully inspected, serviced, and ready before peak storm demand arrives.
Think of it like a pre-season physical for your home’s backup power system. A qualified electrician will assess every critical system, from the engine and battery to the transfer switch and fuel lines, so small issues get caught before they become expensive failures.
What’s Included in a Professional Generator Tune-Up
A thorough generator service appointment covers far more than just checking the oil. When you schedule your generator annual maintenance with Wolverine Electrical Contracting, here’s what our certified technicians inspect and service:
- Engine oil and filter replacement
- Air filter inspection and replacement
- Spark plug check and replacement as needed
- Battery load test and terminal cleaning
- Fuel system and fuel filter inspection
- Transfer switch operation and load test
- Control panel diagnostics and fault code review
- Coolant level check (for liquid-cooled units)
- Visual inspection for corrosion, leaks, and wear
Both Generac and Kohler manufacturer guidelines recommend annual service intervals, and skipping a year can void your warranty. Our technicians are trained on both brands and carry the most common replacement parts on the truck, so most tune-ups are completed in a single visit.
When Maintenance Becomes Generator Repair
Sometimes a spring inspection uncovers more than routine wear. Corroded connections, a failed voltage regulator, or a compromised automatic transfer switch all require prompt generator repair, not just a tune-up. Catching these issues in May, rather than during a July storm, gives you time to source parts and schedule repairs without the added stress of an active outage.
Wolverine Electrical Contracting handles both scheduled maintenance and emergency generator repair throughout Southwest Michigan and Northern Indiana. Whether your unit is throwing fault codes or simply won’t start on its weekly self-test, our licensed electricians diagnose the problem and get your system back online fast.
Don’t Wait Until the Lights Go Out
Standby generators are one of the most valuable investments a homeowner can make, but only if they actually work when the power fails. Proactive generator maintenance is what separates a reliable backup system from an expensive piece of equipment parked in the yard. With storm season approaching, now is the ideal time to act.
