What would happen if the power went out tonight and your generator failed to start? Most homeowners never think about this until they're sitting in the dark, realizing the unit they paid thousands of dollars for hasn't been touched in years. That moment of helplessness is entirely preventable — and that's exactly what this checklist is designed to stop.
Here's the uncomfortable truth: home standby generators are one of the most neglected pieces of equipment in any house. They run their weekly exercise cycle quietly in the background, and because they seem fine, owners assume they are fine. But oil degrades, spark plugs foul, air filters clog, and batteries weaken — especially in climates with extreme heat or cold. When a real outage hits and you need that generator to carry your refrigerator, your AC, and your essential circuits for 48 hours straight, a missed service interval can mean total failure.
Imagine instead flipping that breaker during a storm and hearing your generator fire up within seconds. Within a minute, your kitchen, your freezer, your AC — all back online. Your family is comfortable, your food is safe, and you didn't have to call anyone or panic. That's the outcome a properly maintained generator delivers every single time.
Matt Risinger of The Build Show has built his reputation on doing things right the first time. He's a respected builder and contractor educator with years of hands-on experience, and in his Annual Maintenance Routine video, he walks through every step of a real bi-annual service on his own Champion home standby generator at his house. This isn't a manufacturer's promotional piece — Matt paid for this himself and shares exactly what he does, including a smart battery replacement tip and a clever breaker test to confirm the automatic transfer switch is working correctly. The process applies to Generac, Kohler, and other major brands too.
This PDF checklist captures every actionable step from that video in a clear, sequential format you can print out and take to your generator. No rewinding, no pausing, no second-guessing. Buy the right oil, pull the right parts kit, drain the oil the right way, check the dipstick correctly, reset the countdown timer, and run the transfer switch test that actually confirms your generator will perform when it counts. Everything Matt covers, organized so you can work through it step by step and check each item off with confidence.
Every checklist item comes with actionable notes to guide you — things like "Don't forget to do this before you start," "Avoid this common mistake," or "Set a reminder for 30 days out." Nothing vague, just clear next steps.
