In Ottawa, winter storms and unexpected blackouts are a reality. A standby generator ensures your family stays safe and warm, but only if it’s properly maintained. Neglecting care can lead to costly repairs, poor performance, or even complete failure when you need it most.
This annual generator maintenance checklist will help Ottawa homeowners prevent breakdowns, save money, and extend the lifespan of their backup power system.
Schedule Regular Generator Inspections
An annual inspection by a licensed electrician ensures your system meets local electrical safety standards. Technicians will check wiring, transfer switches, and system capacity to prevent hidden problems.
Change the Oil and Filters
Just like a car, your standby generator relies on fresh oil and clean filters. Ottawa homeowners should:
- Replace oil at least once a year (or after extended runtime).
- Swap out air and fuel filters during routine service.
- Check spark plugs for wear.
Failing to complete these steps could result in generator failure during power outages.
Test Your Generator Under Load
Run your system monthly to make sure it can handle your home’s power needs. For best results, test with major appliances or your HVAC system, ensuring your generator isn’t under or oversized. Learn more in: What Size Backup Generator Does Your Ottawa Home Need?.
Inspect Fuel Systems and Lines
Fuel type impacts long-term maintenance. For example:
- Natural gas generators require professional line inspections.
- Propane generators need tank checks for leaks and corrosion.

Keep the Area Clear and Safe
Always ensure your generator has proper clearance to prevent carbon monoxide risks. Ottawa by-laws require compliance with placement codes. For details, visit: Where to Safely Locate Your Generator in Ottawa.
