Consistent Power Through Proper Care
Frequently asked questions
How often should generator maintenance be performed?
Generators need routine evaluations and maintenance to confirm they will start properly and operate safely when utility power is interrupted. Routine maintenance helps prevent performance issues caused by inactivity or component wear.
What is included in a generator maintenance appointment?
A maintenance visit typically includes inspecting electrical connections, testing the transfer switch, checking batteries, replacing fluids, load testing, and verifying proper startup and shutdown.
Why won’t my generator start after sitting unused?
Extended periods without operation can lead to battery degradation, fuel system issues, or electrical component wear. Regular testing and inspection help prevent startup failures.
Does maintenance help extend the lifespan of a generator?
Yes. Scheduled servicing reduces strain on components, identifies early signs of wear, and keeps the system operating within safe performance standards.
Should generator maintenance be handled by a licensed electrician?
Yes. Because generators tie into your main panel and transfer switch, they require specialized testing and calibration. Professional maintenance verifies proper function, confirms accurate output under load, and ensures the system remains compliant with electrical codes and manufacturer standards.
