When Is the Best Time for Furnace Maintenance?

The best time for furnace maintenance in Ontario is fall — ideally September or October, before you need the heat regularly. Scheduling in fall ensures your furnace is ready before the first cold snap and avoids the rush that happens in November and December when technicians are booked weeks out. (Serving Aurora, Ontario.)

What Does Annual Furnace Maintenance Include?

Yes — skipping annual maintenance has real consequences. Unmaintained furnaces are 10–25% less efficient, more likely to fail during the coldest nights, and pose a higher carbon monoxide risk. Most manufacturers void warranty coverage if annual maintenance wasn't performed. Landlords in Ontario are legally required to maintain heating systems in rental properties.

Furnace Maintenance Costs in Ontario (2026)

Maintenance plans from companies like Reliance Home Comfort, Enercare, or Direct Energy typically cost $20–$50/month and include annual tune-ups plus priority service and discounted repairs. They're worth it if your furnace is more than 5 years old, you don't want to find a technician yourself each year, or you want cost certainty on repairs. For newer furnaces still under manufacturer warranty, a one-time annual tune-up from a local HVAC contractor is often more cost-effective. (Serving Aurora, Ontario.)
