Be careful when you turn on your heater – that funny smell may be telling you that your furnace needs maintenance before the cold weather approaches. While it could be something as minor as a dirty filter – it also could mean you have a serious problem on your hands.

Keep an eye – or nose – out for these different odors especially if they persist!

Furnace filter

Furnace Air Filter

  • Musty odors: This scent typically stems from mold trapped in the furnace filter or humidifier filter. Try cleaning your filters and running a dehumidifier to see if the odor goes away. If the odor persists, it’s best to get a professional involved.
  • Electrical burning odor: This smell is most commonly due to parts or loose connections overheating. It can also be due to a dirty air filter. First, check your air filter to see if airflow is restricted. Then give your unit a visual inspection, look for any object that may have found its way on it and keep an eye out for melted wires. Give us a call for service.
  • Smoke or oil odor: If you have an oil furnace, there is an oil filter inside your unit. Smelling oil when your furnace is turned on can simply be due to a clogged filter that needs cleaning. A smoke smell is usually due to a blocked chimney. You’ll want an HVAC specialist to remove the blockage.

Remember, almost all heating systems cause an odor the first time they are put in use. If you’re worried about what you are smelling – the best solution is to give us a call.
