Generator Maintenance & Servicing
Keep your standby generator reliable with preventive maintenance plans that extend its lifespan and ensure it's ready when you need it most.
A standby generator is only as reliable as its maintenance. Without regular servicing, small issues can go undetected and turn into costly failures — often discovered at the worst possible time, during an actual power outage. Ontario Generator Systems offers comprehensive maintenance plans designed to keep your generator in peak operating condition year-round.
Our certified technicians perform thorough inspections that cover every critical system: engine oil and filter changes, air filter replacement, spark plug inspection, coolant level checks, battery load testing, fuel system inspection, and automatic transfer switch verification. We also update generator firmware and verify Mobile Link connectivity to ensure remote monitoring is functioning properly.
Whether you own a residential Generac unit or a large commercial system, we offer flexible annual and semi-annual maintenance packages. Every service visit includes a detailed condition report with recommendations, so you always know the exact status of your investment. Regular maintenance also preserves your manufacturer warranty and can significantly extend the operational life of your generator.
