How to Prepare Your Furnace for Winter in Scarborough — Fall Checklist 2026
Getting your Scarborough furnace ready before the first cold snap prevents the most common type of emergency call we receive: a furnace that worked fine in spring but fails when first turned on in October or November. Here’s the complete fall furnace preparation checklist.
Fall Furnace Checklist for Scarborough Homeowners
- ✅ Replace furnace filter — Fresh filter before heating season prevents airflow restriction
- ✅ Replace thermostat batteries — Most common “furnace failure” cause in October
- ✅ Clear PVC exhaust/intake vents — Clear any summer debris (nests, cottonwood) from outdoor PVC vent pipes
- ✅ Test furnace before cold weather — Run a full heat cycle in September to confirm all is working before January emergency
- ✅ Book professional tune-up — September/October is the right time. Combustion analysis, heat exchanger inspection, flame sensor cleaning.
- ✅ Check CO detector batteries — Ontario law requires CO detectors in homes with gas appliances
When should I turn on my furnace in Scarborough?
Test your furnace in Scarborough in September — before it’s actually needed for heating. This gives time to book repairs before the busy October–November period. Book your annual tune-up with Madina Mechanical in September for best availability. Call (416) 424-4328.
