A furnace breakdown in the middle of a Toronto winter is more than an inconvenience — it can be a safety emergency. When temperatures plunge below -20°C, your home can lose heat rapidly, putting your family and your pipes at risk. That is why ZK Mechanical offers 24/7 emergency furnace repair across the Greater Toronto Area.
What to Do When Your Furnace Stops Working
- Check your thermostat settings and make sure it is set to heat mode
- Verify the furnace filter is not clogged — a dirty filter can cause shutdown
- Check that the gas valve is in the on position
- Look for error codes on the furnace control board
- If the furnace still will not start, call ZK Mechanical immediately
