Generator Maintenance & Repair

Annual service, diagnostics, and repair — so it starts the night it matters.

At a glance

Annual service

Oil and filter change, battery test, plugs on schedule, exercise-cycle verification — once a year, ideally before storm season.

Diagnostics & repair

Fault codes, failed self-tests, units that start but won't transfer — diagnosed and repaired, including generators we didn't install.

Orphan adoption

Moved into a house with a generator and no service history? We'll inspect it, service it, and put it on a schedule so it's trustworthy again.

Watch for these signs

The weekly self-test has stopped running — or you've never once heard it run.

There's a fault light or error code on the controller you've been ignoring since spring.

It's been more than a year since the oil was changed — or you have no idea when it was.

The generator starts on test day but the house has still gone dark in a real outage — a transfer problem, not an engine problem.

Quick answers

When's the best time for annual service?

Before the season you bought it for — spring ahead of storm season, or fall ahead of ice season. Book it with your HVAC tune-up and make one calendar reminder do both jobs.

My generator won't start its self-test — is that urgent?

Treat it like a smoke detector with a dead battery: nothing is on fire, but the entire reason it exists isn't working. Have it diagnosed before the next storm finds it — the fix is usually small when it's caught early.
