FAQ: What Actually Happens During a GSC Maintenance Visit?

It’s More Than Just an Oil Change

Living in Fishers means we have to stay prepared for just about anything the Midwest weather throws our way. Whether it is a heavy ice storm threatening to snap power lines or the sudden warning sirens of a tornado watch, our local grid faces constant pressure. One of the most common questions we get from neighbors looking to protect their homes is, “My handy neighbor said he could service my generator for cheap. Why do I need a certified plan?”

It is a fair question, but the stakes are higher than they appear. On the surface, a generator looks like a simple engine. Under the hood, however, it is a complex intersection of mechanical systems, high-voltage electricity, and sophisticated software designed to pick up exactly where AES Indiana or Duke Energy leaves off. When a Generator Supercenter technician arrives at your door here in Fishers, they aren’t just there to swap a filter. They are there to perform a forensic health check on your system to ensure it can withstand the freezing cold and the summer storms.

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 during those Indiana winters), 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. It is a vital piece of infrastructure that allows your daily life to continue regardless of what happens with the utility lines. Don’t leave its reliability up to chance or an uncertified generalist.

Service Season is in full swing here in Fishers. If your renewal date is approaching or if you aren’t sure when your unit was last inspected, now is the time to ensure you are ready for the next round of severe weather. You are always welcome to stop by our showroom at 7698 Crosspoint Commons Boulevard to discuss your maintenance options over a coffee, or you can give us a ring at 317-785-1289 to get on the schedule. Let’s make sure that when the grid drops, your power stays steady.
