A standby generator is only useful if it starts when the power goes out. The number one cause of generator failure during outages is skipped maintenance. Dead batteries, degraded oil, clogged filters, and untested transfer switches all contribute to generators that sit silently when they are needed most. Unity Power & Light provides professional generator maintenance throughout Aiken, SC that keeps your backup power system reliable year after year.
We service all major generator brands including Generac, Kohler, Briggs & Stratton, and Champion. Whether you need a one-time tune-up or want to set up an annual maintenance plan, our licensed technicians ensure your generator is ready for the next outage.
What's Included in Our Maintenance Service
Every generator maintenance visit includes a comprehensive inspection and service of all critical components. Here is what we do during a standard maintenance visit:
Oil & Filter Change
We drain the old engine oil, replace the oil filter, and refill with the manufacturer-specified oil type and quantity. Fresh oil protects internal engine components from wear and ensures proper lubrication during operation. We inspect the old oil for signs of contamination, metal particles, or coolant intrusion that could indicate deeper engine issues.
Air Filter Replacement
The air filter prevents dust, pollen, and debris from entering the engine. In the Aiken area, red clay dust and heavy pollen seasons clog filters faster than average. A clogged air filter restricts airflow, reduces power output, increases fuel consumption, and can cause overheating under load. We replace the air filter at every maintenance visit.
Spark Plug Service
We remove and inspect spark plugs for carbon buildup, electrode erosion, and proper gap spacing. Worn or fouled spark plugs cause hard starting, rough running, and reduced power output. We replace spark plugs when they show signs of wear or at the manufacturer's recommended interval, typically every two years.
Battery Load Test
A dead battery is the single most common cause of generator start failure. We perform a full load test on the starting battery, not just a voltage check, to verify it can deliver adequate cranking amps. We clean battery terminals, check charging voltage, and recommend replacement when the battery shows signs of degradation.
Transfer Switch Test
We exercise the automatic transfer switch by simulating an outage and verifying that it correctly signals the generator to start, transfers load from utility to generator, and retransfers back to utility when the simulated outage ends. This end-to-end test confirms the entire system works as designed.
Load Bank Test
We run the generator under actual load to verify it can handle your home's electrical demand. This goes beyond the weekly no-load exercise cycle and confirms the generator performs under real-world conditions. We measure voltage, frequency, and current output to ensure they are within specification.
Additional Inspection Items
Beyond the core service items, our technicians inspect every aspect of your generator system:
Annual & Bi-Annual Maintenance Plans
We offer scheduled maintenance plans that take the guesswork out of generator care. You do not need to remember when your last service was or when the next one is due. We contact you when it is time and schedule at your convenience.
Maintenance plans can be started at any time. If your generator has not been serviced recently, we recommend an initial comprehensive service to bring it up to baseline condition before starting a maintenance plan.
