Weird Furnace Odors You Shouldn’t Ignore

Odd smells coming from a heating system is downright worrisome.  Most homeowners are not aware of what these weird odors mean. They assume that there could be a mechanical problem or some serious issues. Either way, these unusual furnace smells require immediate attention.

Know what they are and what you should do about them through this post.

Musty Odors

A musty odor could be caused by dirt or mold growth in your ducts. This is particularly true if you haven’t had your ductwork or system cleaned regularly. Routine check and service from the pros can prevent this problem and ensure your unit works properly. If the damp smell doesn’t dissipate, the issue could be coming from another part of your home.

Rotten Eggs

Does your furnace smell like rotten eggs? A cracked heat exchanger may be to blame! It’s a pretty serious problem that can put you and your family’s safety in danger. It increases the risk of fire-related hazards and carbon monoxide poisoning. In that situation, the first thing you should do is turn off your heating system.  Evacuate your home immediately then call 911.

Burned Dust

You may be wondering why your furnace smells like fuel. That is normal when you turn it on for the first time. However, a burning dust scent is caused by the dirt that settles in your unit when it is not in use. For a quick fix, change your filter. If the odor doesn’t go away, contact the experts to get the issue resolved.

Metallic Smell

An electrical or metallic smell is a result of an overheating component in your system. It can be caused by frayed wires or broken motors. Trying to fix it on your own can make the situation worse, not unless you’re a NATE-certified technician. We suggest that you bring in the pros to handle the job for you.
