What Do These Furnace Odors Mean in Your Margate, FL Home?

Are there smelly odors coming from the furnace in your Margate, FL home? That could indicate a problem. Let’s discuss some common furnace odors and what they mean.

Rotten Eggs

If your furnace has a sour smell or smells like something is rotten, shut off the furnace. You might have a bad heat exchanger. Contact an HVAC professional for help, as a bad heat exchanger can pump deadly carbon monoxide into your home.

A Musty Odor

A musty odor can mean your ductwork or air conditioning coil has biological growth. An inspection is the only way to determine if this is the problem. If it is, then an HVAC technician can clean the ductwork.

The Smell of Dust

Dust isn’t a pleasant smell, but it’s usually harmless. During the summer, dust will likely accumulate inside your furnace. The dust should burn away after the furnace gets hot.

If the smell lingers, then there’s possibly a more serious issue. An HVAC technician can inspect your furnace for the cause of the smell.

The Smell of Plastic Burning

The smell of something burning is something you should never ignore. The furnace could have an electrical problem, or the wires may be burning. You might also have a fan motor that needs maintenance.

A Sweaty Sock Odor

The smell of a sweaty sock could indicate bacteria on the heating coils. The coils constantly switch between being hot and cold. That creates condensation, which can create an environment for bacterial growth.

An HVAC technician needs to check and clean the coils. If the smell persists, the air ducts and the entire unit might need cleaning.
