Generator service & repair

“The power went out, and the generator never kicked on.”

A standby generator only matters during an outage. That's exactly when you find out it isn't working.

Generator repair usually comes down to a dead or weak battery, old oil or filters, worn spark plugs, a fuel supply problem or a fault code from the controller. Many of these are caught by regular service before they become a no-start in a storm.

Our Winchester team services and repairs Generac standby generators. Your technician checks the engine, battery, fuel supply and controller, runs the generator under load where possible, and gives you a written price for any repair before work starts.

Service or repair

Maintain it, or fix it?

Most no-start problems are cheaper to prevent than to fix in a storm.

Regular service

Keep it ready

Oil, filters, plugs, battery and a running test, so it starts when the power fails.

Once a year at least, more with heavy use.

Repair

Fix the fault

Batteries, starters, controllers, sensors and fuel problems are diagnosed and repaired.

If a part has to be ordered, we tell you when it'll arrive.

Generator service FAQs

Questions about generator service

How often, what's checked and cost.

How much does generator repair cost? +
How often should a whole-home backup generator be serviced? +

At least once a year, and after long run times in a big outage. Oil, filters and the battery wear even when the generator only runs its weekly exercise cycle.

What does a generator technician do? +

Services the engine, tests the battery, checks the fuel supply and controller, reads fault codes, and runs the generator to confirm it starts and carries load. On a repair, they diagnose and replace the failed part.

Why won't my generator start? +

A weak or dead battery is the most common cause, followed by low oil, fuel supply problems, worn spark plugs and controller faults. Check the controller display for a code before you call.

Do you service generators in Norfolk or Wilmington? +

Generator service and repair is offered by our Winchester branch. In Norfolk and Wilmington, our plumbers can help with the gas supply to a generator.
