Dust Burn-Off
A mild burning smell at the first start-up of the season is often dust burning off the heat exchanger. It should fade quickly.
Electrical or Plastic
A sharp electrical or plastic burning smell can indicate an overheating component or wiring issue. Turn the furnace off and request service.
Safety
If you smell gas, leave the building and call your gas utility or 911. Do not operate the furnace.
When to Call
For any persistent or sharp burning smell, request furnace repair or emergency service.
