Why Is My Furnace Giving Off Funny Smells?

You’ve got your furnace running for the winter, providing the warmth your family needs to stay comfortable until the spring thaw. But at some point, you start to notice an odd or unpleasant odor coming from the vents when the furnace is on. Is this a reason to worry, and should you call for professionals to repair the furnace?

There are some odors coming from a furnace that aren’t serious problems, such a dusty smell when the blower turns on for the first time during the season. This smell usually means that the dust collected in the vents is getting blown out of the system. But some strange smells are things you need to worry about. Here are a few to look for:

  • Rotten egg smell: This is an easy odor to identify, and it definitely counts as “unpleasant.” But it also gives you a good idea of what’s wrong, which is a gas leak in a natural gas furnace. Natural gas is normally odorless, but gas companies place a scent in it to allow people to detect it if it starts to leak. If you smell this coming from the vents, turn off the furnace, open up the windows, and call for help from the gas company. You can schedule repairs for the system once the danger of leaking gas and fire hazards is eliminated.
  • Electrical burning smell: Any sort of acrid, metallic mechanical smell from the furnace—something like burning wires—usually means part of the furnace is overheating. It could be rubber or metal parts that are burning because of wear and tear, or it could be a motor that’s on the verge of burning out. Call for technicians to replace these parts before a larger problem develops.
  • Dusty burning odors: As we mentioned above, dusty smells usually aren’t a serious issue. But if the smell continues, you may have a clogged air filter or a furnace that has become overly dirty. If you have an especially old furnace, this may be a sign that it’s time to replace it. It’s also possible that the ventilation system has air leaks that will need sealing. Schedule inspections and repairs if the smell doesn’t go away.
