What a Full Generator Maintenance Service Actually Looks Like

Most homeowners install a standby generator and assume it'll just work when the lights go out. That's a reasonable expectation - but it only holds up if the unit is being maintained properly. A generator that sits untouched for years is a generator that's likely to let you down at the worst possible moment.

Here's what a real maintenance visit looks like. The enclosure is fully opened, the engine is exposed, and we've got everything we need on hand - fresh oil, cleaning solutions, a Valvoline bucket for the drain, and an oil extractor ready to go. This isn't a quick look-and-leave job. We're actually getting into it.

A proper tune-up covers the things you can't see just by glancing at the unit. Oil change, filter inspection, spark plug check, battery test, and a full system exercise to confirm everything transfers and runs the way it should. Each of those steps matters. Skip one, and you've introduced a potential failure point into a system you're counting on when the power goes out.

We work on standby generators of all sizes, and we treat every maintenance visit the same way - thorough, documented, and done right. It's not the most glamorous work, but it's some of the most important work we do. A well-maintained generator is a reliable one, and that reliability is exactly what you paid for when you had it installed.

If your generator hasn't been serviced recently, or if you're not sure when it was last looked at, that's worth paying attention to. Routine maintenance is a lot less painful - and a lot less expensive - than an emergency repair after a failure.
