A generator should not be tested for the first time during a storm. If the power goes out and the generator does not start, it is already too late. A pre-winter tune-up helps confirm that the system is ready before cold weather and outages arrive.
The Generator Should Start and Run Correctly
A tune-up should include starting the generator and making sure it runs properly. The technician should listen for unusual sounds, check operation, and confirm that the unit responds as expected.
If the generator has not run in a while, this step is especially important. Small problems are easier to handle before a storm than during one.
Oil, Filters, and Basic Maintenance Should Be Checked
Like other equipment with an engine, a standby generator needs regular maintenance. Oil, filters, spark plugs, and other service items may need attention depending on the generator, hours, and manufacturer recommendations.
Skipping basic maintenance can shorten the life of the generator and make it less reliable when it is needed.
The Battery Should Be Tested
A weak battery can stop a generator from starting. Battery condition should be checked before winter, especially if the unit is older or has not been serviced recently.
A generator can have fuel and still fail if the battery cannot start the engine.
Fuel Supply Should Be Reviewed
The fuel source should be checked to make sure the generator has what it needs to run. Fuel connections, supply, and general condition should be reviewed as part of the service process.
The exact fuel checks depend on the system. The important point is that fuel should not be assumed. It should be confirmed.
The Transfer Switch Matters Too
The transfer switch is part of the generator system. It controls the connection between utility power and generator power.
A generator tune-up should include attention to the transfer switch and how the system responds when backup power is needed. The generator and electrical connection need to work together.
When Should You Schedule Generator Service?
The best time to schedule generator service is before winter storm season, not after the first outage. Fall is a practical time to check the system and address problems while there is still time.
If the generator has not been serviced recently, schedule it before heavy weather arrives.
A generator tune-up is about readiness. The system should start, run, transfer power properly, and be maintained before the weather tests it.
