Generator Service Before the Power Goes Out

Most generators sit for months and then get asked to run all night. We do the routine maintenance where they're stored — oil, filters, drain old fuel from the carb bowl and a test run — so they're ready when you need them. Carb cleaning and output/electrical testing are repair work if you want them.

Standby generators and transfer switches

We maintain the engine on standby units, but we don't do any electrical connection to your home. Transfer switches, inlets and interlocks must be installed by a licensed electrician. If you tell us your portable unit plugs into a transfer switch or inlet, we'll test the generator side and point out anything you should have an electrician check.

Ranch and acreage owners: well pumps, stock-tank heaters and calving barns are exactly why generators matter here. We're glad to service several units on one visit. Outlying places like Meeteetse are scheduled with Cody days. In town, Cody and Powell have no trip fee.

Generator questions

How often should a generator be serviced?

Once a year for most home generators, and before storm season. Running it under load for 15–20 minutes once a month keeps the carb from gumming up.

Do you work on standby generators?

We'll inspect and maintain the engine side (oil, plug, filter, a look at the battery and the exercise cycle). Any wiring between the generator and your house, including the transfer switch, needs a licensed electrician.

Can you service an inverter generator?

Yes. Honda, Yamaha, Champion, Predator, Westinghouse and similar inverters get the same $150 maintenance service. Output/voltage testing is repair work if you want it.
