No Heat? Emergency Furnace Repair Guide
A furnace with no heat in winter is urgent — here's what to check and when to call for emergency service.
Losing heat during a BC cold snap is stressful, especially for families with young children or elderly residents. Run these quick checks, then call for emergency service if heat doesn't return.
Fast checks before you call
Confirm power, breaker, thermostat (HEAT mode, batteries), the furnace switch, and the filter. Reset the furnace once by cycling its switch off for 30 seconds. Do not repeatedly reset a unit that keeps locking out.
When to call for emergency service
If there's no heat after these checks, or you smell gas, hear repeated clicking with no ignition, or see error codes, call for emergency repair. In freezing weather, protect pipes and use safe space heating while you wait.
Key takeaways
- Check power, thermostat, switch and filter first
- Reset the furnace only once
- Never use the oven or unvented heaters for warmth
- Call emergency service if no heat returns
