Why Generator Maintenance Matters

Standby generators often sit unused for extended periods of time. Routine maintenance helps ensure that critical components such as filters, oil, spark plugs, and batteries are ready when the system is needed.

Annual service can help:

Improve reliability
Extend equipment life
Reduce unexpected failures
Maintain manufacturer service intervals
Provide peace of mind during storm season

Frequently asked questions

How often should my home standby generator be serviced?

Most standby generators should be serviced once a year or every 100–200 hours of operation, depending on the manufacturer's recommendations. Regular maintenance helps ensure your generator is ready when you need it most.

What is included in a standard generator service?

Our standard home standby generator service includes replacing the spark plugs, changing the engine oil, replacing the oil and air filters, inspecting the battery and electrical connections, checking for leaks or damage, and performing a general inspection of the generator's overall condition.

Do you service generators you didn't install?

Yes. We service most residential standby generators, even if they were installed by another contractor, provided parts and service information are available.

What generator brands do you service?

We routinely service residential standby generators from Generac, Kohler, Briggs & Stratton, Cummins, Honeywell, and many other major manufacturers.

How long does generator maintenance take?

Most routine generator maintenance appointments take approximately 1 to 2 hours, depending on the generator model, condition, and whether additional repairs or testing are needed.

What happens if you find a problem during the service?

If we discover worn components, leaks, battery issues, or other concerns during the inspection, we'll explain our findings and provide recommendations before performing any additional repairs.

Is a transfer switch test included?

A simulated power outage transfer test is available as an optional add-on service. This test verifies that the generator starts automatically, transfers power correctly, and restores utility power properly once service is restored.

Do you remind customers when their next service is due?

Yes. We can help you stay on schedule with routine maintenance so your generator continues operating safely and reliably year after year.

Why is annual generator maintenance important?

Regular maintenance helps extend the life of your generator, improve reliability during power outages, reduce the risk of unexpected failures, and keep the generator operating according to the manufacturer's recommendations.

How do I prepare for my service appointment?

Please ensure the generator is accessible and free of vegetation, debris, or stored items. If available, have your generator model and serial number handy before the appointment.

Can a standby generator lose reliability if it isn't serviced regularly?

Yes. Engine oil breaks down over time, batteries weaken, filters become dirty, and spark plugs wear out. Without regular maintenance, these issues can reduce reliability and increase the chance of your generator failing during a power outage.
