How often should I service my backup generator?

Backup generators require regular maintenance every 6 months or after 100-200 hours of operation to ensure they'll start when you need them most. Missing scheduled maintenance is the #1 reason generators fail during power outages.

Routine Maintenance Schedule:
Your generator needs attention twice yearly - ideally in spring and fall before Ottawa's storm seasons. This includes changing the oil (every 50-100 hours), replacing the air filter, checking spark plugs, and testing the battery. The fuel system also needs attention - gasoline can go stale in 3-6 months without stabilizer, while propane and natural gas systems need their connections and regulators inspected.

What Maintenance Includes:
A proper service involves checking all fluid levels, testing the automatic transfer switch, verifying proper voltage output, and running the unit under load for 15-30 minutes. The cooling system, exhaust, and electrical connections all need inspection. For standby generators, the control panel should be tested to ensure it properly senses power outages and starts automatically.

Ottawa Climate Considerations:
Our harsh winters put extra stress on generators. Cold weather affects battery performance and oil viscosity, making spring maintenance crucial after winter storage. Summer humidity can cause fuel issues, while fall preparation ensures your generator is ready for ice storms and winter outages that are common in the Ottawa area.

Professional vs. DIY Maintenance:
While you can check oil levels and keep the area clear of debris, most maintenance requires technical knowledge. Electrical connections, transfer switch testing, and gas line inspections must be done by licensed professionals to maintain warranty coverage and ensure safety. Improper maintenance can create carbon monoxide risks or electrical hazards.

ESA Requirements:
In Ontario, any electrical work on your generator system requires proper permits and ESA inspection. This includes transfer switch installation, electrical connections, and any modifications to your home's electrical system. Only ESA-licensed electricians can legally perform this work.

Signs Your Generator Needs Immediate Service:
Don't wait for scheduled maintenance if you notice hard starting, rough running, unusual noises, or if it fails to start during your monthly test run. Burning smells, sparking, or any electrical issues require immediate professional attention - shut down the unit and call for emergency service.
