Ontario has seen a lot of snow lately, and that snow can cause your furnace vent to be blocked by snow causing a serious winter problem many homeowners don’t think about.
If snow covers your furnace exhaust or hot water tank vent, your heating system may stop working—or worse, exhaust gases may not vent safely outside.
This is especially important in older Ontario homes that have been upgraded with high-efficiency furnaces. These newer systems often use white PVC pipes that vent out the side of the house, close to the ground – right where snow builds up. This is one of many important safety checks that home inspectors in Ontario look for.
What to check after every snowfall
- Look for PVC intake and exhaust pipes on the outside wall
- Make sure they are clear of snow and ice
- Gently clear snow away by hand (do not hit the pipes)
Even partly blocked vents can cause furnace shutdowns, no heat, or safety issues.
Why this matters
Blocked vents can:
- Shut down your furnace in cold weather
- Cause poor furnace performance
- Create unsafe venting conditions
A quick outdoor check can help keep your home warm, safe, and comfortable.
