Call when the furnace will not start, when it turns on and off every few minutes, when you hear or smell something new, or when your bill climbs without colder weather to explain it. If you smell gas or a carbon monoxide alarm sounds, leave the house first and call from outside.
Check these yourself first
- Is the thermostat set to heat, with working batteries?
- Is the furnace filter clogged?
- Is the furnace switch on, and has a breaker tripped?
- Are the vents and the outdoor intake clear of snow?
Call a professional when
- There is no heat after those checks
- The furnace short cycles
- You hear banging, grinding or squealing
- Some rooms stay cold
- The pilot or burner flame is yellow instead of blue
- Your furnace is 15 years old or more and repairs are becoming regular
