Home / Blog Is Your Furnace Producing Any Unusual Smell? Here Is What You Should Do!


We all look at our home furnace as soon as fall begins and makes us shiver. Our home furnace is designed to provide us safe, clean, and smooth function throughout the winter. But, if you have started noticing unexplainable and unusual odors coming from your furnace, it can be an indication that your furnace system has some issues. Calling an HVAC service in Killeen, TX, is the most recommended step when you experience any weird smell coming out from your furnace. Here are some common types of furnace smells that you should never ignore.

The Smell of Rotten Eggs

Rotten eggs smell like sulfur. If your furnace system is smelling like rotten eggs, that is a cause for serious alarm. Utility companies put odor-causing substances in odorless natural gases so that a gas leakage can be easily recognized. If you smell this type of smell inside your room, it could indicate that your furnace is leaking natural gas. It can cause a disastrous fire explosion inside your home. Take immediate action.

  • Evacuate your home at once.

  • Reach a safer place and call an HVAC service in Killeen, TX, for assistance.

Musty Smell

If your furnace has mold formation inside the system, you may notice a musty smell coming out from the system. Mold can grow in the ductwork or the coil that is mounted above your furnace. You need to take the necessary actions such as inspection and cleaning. Or,

  • Shut off the furnace.

  • Call a professional HVAC service in Killeen, TX.

  • Let the professional HVAC contractor do a thorough scan of the system and make necessary fixes.

Dusty or Burning Smell

When your furnace starts for the first time during winter, you may sense a burning or dusty smell coming out from the system. This is a normal phenomenon in most cases, and once the dust inside the system blows away, the smell will stop. But, if the odor persists, it is an indication that there is a severe problem with your furnace. In such a case, you need to give the furnace some time to get rid of that accumulated dust. If you haven’t changed your air filters for a long time now, change the furnace filters to see if the odor goes away. However, if the smell continues, call a professional furnace repair in Killen, TX, for technical help.

Metallic or Overhead Smells

If any component inside your home furnace is getting too hot, it may produce a smell similar to hot metal, hot plastic, or burning oil. If any smell suggests something like your furnace is overheating or burning—

  • Shut the furnace immediately and unplug it.

  • Call a professional HVAC service in Killen, TX, for inspection and repair.

  • Monitor the furnace for a few hours and make sure there is no fire or further problems.
