Emergency Furnace Repair in London Ontario and within 50km of London: What to Do When Your Heat Stops

First, check your thermostat settings—ensure it's set to 'heat' mode and the temperature is higher than room temperature. Replace batteries if needed. Then check your circuit breaker for a tripped furnace breaker. Finally, inspect your air filter—a dirty filter is the #1 cause of furnace problems. If these steps don't restore heat, call a professional immediately. Don't wait—frozen pipes can cause extensive damage.

A furnace issue is an emergency when you notice: unusual noises (banging, rattling, grinding), strange odors (burning smell or rotten egg gas smell), carbon monoxide alarm triggering, yellow or flickering pilot light (should be blue), complete loss of heat in freezing weather, or puddles around the furnace. If you experience any of these, call for emergency repair immediately. Don't wait until morning—these are safety hazards.

Layer up with warm clothing and blankets, gather in one room to conserve body heat, seal drafts with towels under doors, let faucets drip to prevent frozen pipes, open cabinet doors under sinks, and ensure CO detectors are working. Never use ovens or stoves for heat—they pose fire and CO risks. Portable space heaters are safe if rated for indoor use and monitored.
