Strong and unpleasant odors should not come from your furnace when you try to operate it this winter in Mount Zion, IL. If they do, you can be sure that something is wrong, though it may not be immediately obvious what that is. Below, we’re going to discuss three different furnace smells and what their emergence means.


The smell of sulfur is typically so awful that it’s nearly impossible not to notice. It resembles the pungent odor of rotten eggs and indicates that your furnace is likely experiencing a natural gas leak.

Once you notice this smell, turn your furnace’s shutoff valve if it is at all possible to do so safely. This will cut off the supply of natural gas to the furnace and keep the problem from becoming worse. After that, call an HVAC professional and schedule an appointment to inspect and repair your furnace as soon as possible.

Burning Smell

Your furnace may temporarily release a burning smell if it has been off for a long time. This happens because dust has probably accumulated all throughout the unit after you stopped using it, and the burning smell is the natural result of dust and hot air coming together.

This smell should not persist for a long time, however. If it does, it means that your furnace is overheating, probably as a result of either a broken blower motor or an accumulation of dust, soot or some other kind of debris gathering in the interior and inhibiting airflow. In this case, you’ll need professional repair or maintenance services to deal with the problem.

Damp or Musty Smell

The explanation for this odor is that somehow, water found its way into your furnace. This might have happened because the hose connecting to your furnace’s drain pan, which should get rid of excess moisture, has somehow come loose.

Your nose is one of the best tools you have to help you detect issues with your furnace. If something doesn’t smell right, call Tica, Inc. Heating and Cooling and enjoy the best furnace repair services around Mount Zion, IL.
