heating and air conditioningHave you noticed a funky odor hanging around your home recently? It may not be your dirty laundry, your cat’s litter box, or the trash you forgot to take out last week. You’re probably thinking it’s no big deal, but in reality, that stink could be an indication that something is wrong with your heating and air conditioning system.

So, what do malfunctioning heating systems smell like? If any of the following odors seem familiar to you, it may be time for an HVAC repair.

  1. Smoke
    If you notice a smoky smell coming from your vents, chances are you have a mechanical or electrical problem. It is possible that a motor is being overworked or a fan is seizing up, causing the whole unit to overheat. Shut off your heating and air conditioning system immediately.
  2. Mold or Mildew
    Does it smell damp and musty? This is a sure sign that you’ve got mold or mildew growing in your ductwork. If this is left untreated, the mold will spread and could cause serious health problems to everyone living in your home. Cleanup is crucial, but getting to the root of the problem is even more important. It’s likely that the drainage tubes in your heating and cooling system are blocked or there is leaky ductwork and poor insulation.
  3. Oil
    It’s normal for a new furnace to emit an odor that smells like burning oil for the first 24 hours of operation, but if you still notice the smell after a couple days, something could be wrong. In this case, it is likely that the oil burner is not functioning as it should. You could have a clogged burner or a faulty fuel pump, for instance. If you see smoke and/or soot or hear strange noises, the problem could be a lot more serious.

The average furnace is expected to last up to 20 years. If your furnace or HVAC system is older, you’re bound to run into one of these problems eventually.
