Generator Maintenance

Generator Maintenance — Reliable Power When You Need It Most

A standby generator only works the way it should when it’s properly maintained.

Regular service helps ensure your generator starts automatically, runs smoothly, and delivers power during outages without surprises.

At Andrew Ells-O’Brien — Journeyman Electrician, I provide generator maintenance focused on reliability, safety, and keeping your backup power system ready year-round.

Need Generator Maintenance or a System Check?

If it’s been a while since your generator was serviced—or you want to confirm it’s ready—I can help.

  • Generators often sit idle for long periods—until the moment they’re needed most.

    Without routine maintenance, issues can go unnoticed until a power outage occurs.

    Regular service helps:

    • Ensure reliable startup during outages

    • Prevent unexpected failures

    • Extend equipment lifespan

    • Maintain safe operation

    • Catch small issues before they become major problems

    💡 A generator is only useful if it works when the power goes out.

  • If you notice any of the following, it’s time for a checkup:

    • Difficulty starting or delayed startup

    • Warning lights or error codes

    • Unusual noise or vibration

    • Fuel or oil leaks

    • Inconsistent operation during testing

    • Haven’t had service in over a year

    Even if everything seems fine, preventative maintenance is still important.

  • Routine Inspection

    • Visual inspection of unit and wiring

    • Checking for wear, corrosion, or damage

    • Verifying proper mounting and connections

    System Testing

    • Startup and load testing

    • Automatic transfer switch verification

    • Confirming proper voltage output

    Electrical Checks

    • Battery condition and charging system

    • Wiring and connection inspection

    • Control panel diagnostics

    General Service

    • Filter checks and replacement recommendations

    • Fluid level inspection (when applicable)

    • Cleaning and system tune-up recommendations

  • Your transfer switch is what allows your generator to automatically take over during a power outage.

    I verify:

    • Proper switching between utility and generator power

    • Safe reconnection when utility power returns

    • Secure electrical connections

    • Proper operation during simulated outages

    • Batteries failing from lack of maintenance

    • Units not starting during outage tests

    • Fault codes due to skipped service

    • Dirty or corroded connections

    • Transfer switch issues preventing proper operation

    • Thorough, not just a quick visual check

    • Focus on real-world outage readiness

    • Clean, careful electrical inspection

    • Clear explanation of system condition

    • Honest recommendations—no unnecessary upsells

    • Review of your generator system setup

    • Full inspection and operational testing

    • Identification of any issues or concerns

    • Maintenance recommendations (if needed)

    • Confirmation that system is ready for use

  • Most standby generators should be serviced:

    • At least once per year, or

    • Per manufacturer guidelines, or

    • After extended outages or heavy use

    Regular testing between service visits is also recommended.

  • A properly maintained generator means:

    • Your home stays powered

    • Critical systems keep running

    • You avoid emergency repair situations

    • You’re not left guessing during storms or outages
