Why it matters

Why generator maintenance matters

Your standby generator runs a short exercise cycle automatically each week — but that confirms it starts, not that every component is healthy. Regular professional maintenance helps:

  • Ensure reliable startup the moment an outage hits
  • Extend engine life
  • Maintain fuel efficiency
  • Prevent battery failure — the most common cause of a no-start
  • Catch small issues before they turn into costly repairs

Service schedule

How often should you service a generator?

Most manufacturers recommend annual maintenance — and an extra inspection after extended runtime during a major outage. If your generator ran for hours during a storm, a post-outage check is one of the smartest things you can do to keep it dependable for next time.

Generator maintenance FAQs

Frequently asked questions

How often should I service my standby generator?
Most manufacturers recommend professional maintenance once a year, plus an inspection after any extended runtime during a major outage. If your generator ran for several hours during a storm, scheduling a post-outage check is a smart move.
If my generator runs a weekly exercise cycle, why does it still need professional service?
The weekly exercise cycle confirms the unit starts and runs, but it doesn't replace hands-on inspection. Oil, filters, the battery, fuel system, and electrical connections all wear over time, and a technician catches those issues before they leave you without power in an outage.
What is included in a generator maintenance visit?
A typical visit includes an oil and filter inspection, battery testing, a fuel system inspection, an electrical connection check, a transfer switch inspection, and a full diagnostic scan and system status check.
Can you service any brand of standby generator?
Yes. As an independent, veteran-owned local company, we service standby generators from all major brands — not just one manufacturer. Call (614) 855-9010 and we'll confirm we can service your specific unit.
What are the signs my generator needs service?
Watch for a generator that fails its exercise cycle or won't start, a warning or amber status light, rough running or alarms, visible leaks, or a unit that hasn't been serviced in over a year. Any of these is worth a call before the next outage.
