When your furnace won't start on a cold Regina morning, don't panic. Many common issues have simple solutions you can try before calling for professional help.
Quick Checks Before Calling
Check Your Thermostat
- Make sure it's set to Heat mode
- Set the temperature 5 degrees higher than current room temperature
- Replace batteries if it's battery-powered
- Check that the display is working
Look at Your Circuit Breaker
- Check if the furnace breaker has tripped
- Look for a breaker in the off position
- Reset any tripped breakers
- Wait a few minutes, then try starting the furnace
Check Your Air Filter
- A completely clogged filter can shut down your system
- Remove and inspect the filter
- Replace if it's dirty or blocked
- Try starting the furnace with a clean filter
Gas Supply Issues
- Make sure other gas appliances are working
- Check that the gas valve to the furnace is open
- Look for any gas smell (if present, leave immediately and call the gas company)
Common Warning Signs
Call a professional immediately if you notice:
- Strong gas odors
- Yellow or orange flames (should be blue)
- Soot around the furnace
- Frequent cycling on and off
When DIY Isn't Enough
If these basic checks don't solve the problem, you likely need professional diagnosis. Common issues requiring a technician include:
- Faulty ignition system
- Broken flame sensor
- Blocked venting
- Thermostat wiring problems
Emergency vs. Regular Service
Call for Emergency Service If:
- You smell gas
- Carbon monoxide detector is alarming
- It's extremely cold outside and you have no heat
Regular Service Appointment If:
- The problem started gradually
- Some heat is working but not enough
- The issue isn't urgent
Preventing Future Problems
- Schedule annual maintenance
- Change filters regularly
- Keep the area around your furnace clear
- Don't ignore unusual sounds or smells
Remember, when in doubt, it's always safer to call a professional. A small repair bill is much better than a dangerous situation or major system damage.
