How Often Should a Whole-Home Generator Be Serviced?

Most whole-home generators should be serviced at least once a year or after every 100–200 hours of use. Regular maintenance ensures reliability during outages. Check your owner’s manual for manufacturer-specific recommendations.

What Does Routine Generator Maintenance Include?

Routine maintenance includes changing the oil and oil filter, replacing air and fuel filters, checking spark plugs, and testing the battery. Technicians also inspect fuel lines, tighten electrical connections, and run performance diagnostics. These steps keep the generator running smoothly and extend its lifespan.

Why Is Generator Maintenance Important?

Regular maintenance ensures your generator will operate correctly during power outages. It prevents unexpected breakdowns, extends equipment life, and keeps warranties valid. Neglecting maintenance can result in costly repairs or failure when you need it most.

Can I Perform Generator Maintenance Myself?

You can handle basic tasks like checking oil levels or replacing the air filter if you’re comfortable. However, professional servicing is recommended for more complex inspections and tune-ups. A licensed technician ensures everything is working safely and meets manufacturer guidelines.

How Do I Know If My Generator Needs Maintenance?

Warning signs include trouble starting, unusual noises, visible leaks, or a failed self-test. Some models have indicator lights or digital displays to alert you when service is due. If your generator hasn’t been run in a while, a professional inspection is a good idea.

Should I Run My Generator Regularly?

Yes, most standby generators perform weekly self-tests to stay operational. If yours doesn’t, manually running it for 10–15 minutes each month helps keep the engine and components in good shape. Regular exercise also prevents fuel from going stale.

How Long Does Generator Maintenance Take?

A standard maintenance visit usually takes one to two hours. More in-depth service or repairs may take longer depending on the issue. Many companies offer annual maintenance plans for convenience and peace of mind.

Does Generator Maintenance Affect My Warranty?

Yes, most manufacturers require regular maintenance to keep the warranty valid. Be sure to keep records of all service work, especially if done by a professional. Skipping scheduled maintenance could void your warranty coverage.
