Generator Maintenance & Service Plans | Charlotte

Generator service across the Charlotte metro

A standby generator is only as dependable as the care it receives. It sits idle most of the time, running short weekly exercise cycles, but the engine, oil, filters, and battery still wear with age. Routine service is what makes sure your generator starts and carries the load during a real outage. Power Source maintains and repairs all major brands across the Charlotte area, whether we installed your unit or not.

Why Maintenance Matters

Oil degrades, filters clog, and battery connections corrode over time. A generator that seems fine on its weekly test can still fail under the sustained load of an actual outage. Regular service catches those issues early, and it protects your warranty: as an authorized dealer we perform the preventive maintenance your manufacturer's warranty requires.

What a Maintenance Visit Covers

Every visit follows a full preventive-maintenance checklist, with any extra steps the manufacturer calls for on top.

Pre-Start Checks

Engine fluid levels, fuel-line filter, and coolant or fuel hoses
Battery load test, terminal cleaning, and water level
Spark plugs and plug wires, with plugs changed yearly on air-cooled units
Oil and filter change (yearly), and all electrical connections
Clean the enclosure louvers

Engine-Running Checks

Output voltage and AC output frequency
Electronic controls and transfer-switch operation
Fluid connections for leaks and engine temperature
Any unusual vibration or noise

Frequently Asked Questions

At least once a year for most homeowners. A Bronze plan covers that annual visit; units that run often do better with added monitoring.

Bronze is the full preventive-maintenance visit. Silver adds Mobile Link app monitoring and alerts on Generac Wi-Fi units. Gold adds a cellular module so Power Source monitors your generator around the clock and dispatches automatically if it fails.

Usually yes. Most manufacturers require documented service at set intervals, and skipping it can void coverage. A maintenance plan keeps that record for you.

Yes. We service and repair all major brands, no matter who installed the unit, with 24/7, 365-day emergency support.
