A standby generator is an engine that sits idle for months at a time, waiting for the moment it's needed most. Without regular maintenance, that engine may not start when a January ice storm or September hurricane remnant takes down your power. Never Dark's generator maintenance service keeps your system in peak condition so it performs flawlessly the day you need it.
Our standard annual maintenance visit includes a comprehensive 21-point inspection. We change the oil and oil filter, replace the air filter, inspect and gap the spark plugs, check battery voltage and clean the terminals, verify the battery charger is functioning, inspect the fuel system for leaks, test the automatic transfer switch operation, and run the generator under load to confirm it performs to specification.
In the Carolinas, we also recommend a pre-storm season checkup in late spring. Hurricane season runs June through November, and the remnants that reach Upstate South Carolina can cause multi-day outages. We verify your system is ready before the season starts, not after the first outage reveals a problem.
For customers who want total peace of mind, our maintenance plans include priority emergency service, discounted repair rates, and automated reminders so you never miss a service interval. Plans start at $199 per year and include the full annual inspection plus unlimited diagnostic visits.
Regular maintenance also protects your warranty. Most manufacturers require annual service by a certified dealer to keep the warranty in force. Skipping maintenance - or using an uncertified technician - can void your coverage. As an authorized dealer for Generac, Kohler, Cummins, and Kenerator, our service counts toward your warranty requirements.
Don't wait for the next ice storm to find out your battery is dead or your fuel filter is clogged. Annual maintenance catches these issues during a scheduled visit, not during a 2 a.m. outage when your family is in the dark.
