Losing heat is stressful, and if your property is a waterfront cottage or seasonally-occupied home around Kempenfelt Bay, Lake Simcoe, or Oro-Medonte, there’s an added risk worth checking first: frozen pipes.
If It’s a Seasonal or Waterfront Property
Check whether the water supply has already frozen, especially if the property has been unoccupied for any stretch of time. A furnace failure combined with an empty house is how a simple no-heat call turns into a burst-pipe situation — the two problems compound fast in a property that isn’t being checked on daily.
Check the Basics First (Any Property)
- Thermostat — is it set to Heat, and is the target temperature above the current room reading? Check batteries if it’s battery-powered.
- Breaker panel — has a breaker tripped for the furnace circuit?
- Furnace switch — many furnaces have a wall switch near the unit that looks like an ordinary light switch. Easy to bump off in a basement or utility room.
Check the Filter
A severely clogged filter can cause a furnace to overheat and shut itself down as a safety measure. If it’s visibly caked with dust, replace it and see if the furnace restarts after a few minutes.
Look for an Error Code
Most modern furnaces have a small window showing a blinking light code. Photograph the pattern before you call — it tells a technician exactly what fault the furnace is reporting, which speeds up the repair.
What Not to Do
Don’t take apart the furnace cabinet, don’t reset the system repeatedly hoping it “catches,” and don’t attempt any gas line or ignition work yourself. Gas components should only be handled by a TSSA-licensed technician.
When to Call
If the basics check out and the furnace still won’t run — or you smell gas at any point — stop troubleshooting and call immediately. For a seasonal or waterfront property, treat a furnace failure as urgent even if nobody’s currently living there full-time; an unheated house in a Barrie-area winter risks frozen pipes within days, not weeks.
