FAQ: What Actually Happens During a GSC Maintenance Visit?

It’s More Than Just an Oil Change

One of the most common questions we hear around town is, “My handy neighbor said he could service my generator for cheap. Why do I need a certified plan?”

It’s a fair question. On the surface, a generator looks like a simple engine. But under the hood, it is a complex intersection of mechanical systems, high-voltage electricity, and sophisticated software. Here in Delafield, where we face everything from the biting cold of a Polar Vortex to the heavy, wet snow of spring blizzards, “good enough” simply isn’t enough. When a Generator Supercenter technician arrives at your door, they aren’t just there to swap a filter. They are there to perform a forensic health check on your system to ensure it’s ready to back up the We Energies grid the moment you need it.

We want to pull back the curtain and show you exactly what happens during a professional maintenance visit.

The Multi-Point Inspection Checklist

When our truck pulls up, our technicians are following a strict, factory-approved protocol designed to catch issues before an outage occurs.

The Fluid Analysis: Yes, we change the oil and filters (using synthetic oil for better cold-weather performance), but we also inspect for leaks, check coolant levels in liquid-cooled units, and ensure the fuel lines are intact and free of dry rot.

The Electrical Health Check: A generator is useless if it can’t deliver clean power. We check the output voltage and frequency (Hertz) to ensure the electricity produced is safe for your sensitive electronics, like laptops and smart fridges.

The Battery Load Test: This is the #1 culprit for failed starts. We don’t just check the voltage; we put the battery under a “load” to simulate a cold start. If it can’t handle the stress, we replace it before you need it.

Firmware & Software: Just like your phone, modern generators need updates. We check the controller firmware to ensure your unit is running the latest logic for efficient operation.

The Transfer Switch: We inspect the automatic transfer switch—the brain of the operation—to ensure it will seamlessly disconnect you from the grid and move you to generator power without delay.

The “Silent Watchdog”: GenMon Monitoring

Beyond the physical visit, our service plans often include GenMon (Generator Monitoring). Think of this as a 24/7 digital technician.

While you are sleeping or away at work, GenMon is watching your generator. If the unit misses its weekly self-test, or if the battery voltage drops slightly, our support team gets an alert instantly. In many cases, we know about a problem before you do. This allows us to be proactive rather than reactive, fixing minor issues so they don’t become major failures during a storm.

Don’t Wait for the Dark to Test It

Your generator is an investment in your home’s value and your family’s safety. Don’t leave its reliability up to chance or an uncertified generalist.

Service Season is in full swing here in Delafield. We know the weather here can turn quickly, shifting from humid summer storms to freezing winter conditions in the blink of an eye. If your renewal date is approaching, or if you aren’t sure when your unit was last inspected, now is the time to get on the schedule. You don’t have to face the Blizzards, Polar Vortex, or summer squalls alone. Stop by our showroom at 2846 Heritage Dr. to chat about your maintenance schedule, or give us a friendly ring at 262-622-6220. Let’s make sure that when the grid drops, your power stays steady.
