We completed a comprehensive preventative maintenance service on this air-cooled Generac Guardian standby generator in Cleveland, Texas. Our team performed a full system inspection, including an oil and filter replacement to ensure the engine runs efficiently. We also verified the integrity of all electrical connections between the transfer switch, conduit lines, and the utility meter. These routine maintenance procedures ensure the generator remains fully operational and ready to provide backup power when needed. This service helps extend the lifespan of the equipment and confirms all components function correctly under load settings.
