A generator, like a car, should have regularly scheduled maintenance and service performed on it. We recommend at least once a year, but based on run time hours accumulated the unit may require maintenance more often than once a year. We provide full service and will arrange a maintenance schedule for your generator. We also winterize generators for those who only use their dwellings in the warmer seasons. Cummins Onan generators and engines are supported by the largest and best-trained worldwide certified distributor/dealer network in the industry. That means that when you need help, a Cummins Onan distributor/dealer is nearby. This extensive network makes it easier to get genuine Cummins Onan parts, quality service, and expert installation assistance when and where you need them.
