Generator FAQ

Most manufacturers recommend annual service — including an oil change, filter replacement, spark plug inspection, battery test, and full system check. In Florida, where generators run harder during storm season, some high-usage units benefit from service every 6 months.

A service plan is a prepaid annual maintenance agreement that covers scheduled tune-ups, inspections, and often includes priority scheduling and discounts on repairs. It's the most cost-effective way to maintain your generator and keep it under warranty.

A generator that starts and immediately shuts down is often caused by a low oil condition, a coolant issue, an overcrank or overspeed fault, or a faulty sensor. Call us for a diagnosis — this is one of the most common service calls we handle.

The most common causes are a dead or weak battery, stale fuel, a clogged fuel line, or a fault code lockout. If your generator won't crank at all, start with the battery. If it cranks but won't fire, call a technician for a proper diagnosis.

We service all major generator brands including Generac, Kohler, Briggs & Stratton, Cummins/Onan, Honeywell, Guardian, and more. If it runs on natural gas, propane, or diesel, we can service it.

A properly maintained standby generator should last 20 to 30 years. Annual service and proper load management are the keys to a long generator lifespan.

Air-cooled generators use a fan to cool the engine and are typically used for residential applications under 22kW. Liquid-cooled generators use a radiator and coolant system, handle larger loads, and require more complex maintenance.

If your generator runs during its exercise cycle but doesn't transfer during an outage, the most common culprit is a faulty transfer switch or a utility sensing issue.

It depends on the size of the generator and your home's power demands. We can help you size correctly.

A standard annual tune-up for a residential generator typically ranges from $150 to $300 depending on the model and what it needs. Contact us for a specific quote.
