A generator is a promise. Maintenance keeps it.
Here's the uncomfortable truth about standby generators: they sit idle for months, then have to perform perfectly on the worst night of the year. The units that fail during outages aren't usually broken — they're neglected. Dead battery. Old oil. A fault code nobody noticed because nobody looked since installation day. Every one of those is preventable, and prevention is what a maintenance plan is.
What's included
Annual full service: oil and filter change, air filter service, spark plug check, battery load test, coolant check (liquid-cooled units), fuel system inspection, transfer switch inspection, control panel check, and a full-load test simulating an outage. Battery replacement when testing shows weakness — before it becomes a failure. Priority scheduling: plan members jump the queue for repairs, especially during and after storms when everyone calls at once. Service records: documented maintenance history, which protects your warranty and your resale value.
What it costs vs. what it prevents
Annual maintenance runs a few hundred dollars — against a $10,000–$20,000 investment that exists for one purpose. Skipping it to save $300 is like skipping oil changes on a car you need for a cross-country drive. The math only works one way. And most generator warranties require documented maintenance — skip service and you may be skipping warranty coverage too.
