What's That Burning Smell Coming From My Furnace Vents?

Is there a burning smell coming from your gas furnace vents? Here’s what to do.

What Is That Burning Smell Coming From My furnace Vents?

Ahh, the San Antonio winter. Though it doesn’t get as icy as other parts of the country, it does require us to flip the switch on our furnaces. One common concern many homeowners face when they first start up their furnace is a burning smell coming from the vents. If you’ve experienced this, you’re not alone! Let’s dive into what might be causing this scent and what you can do about it.

Possible Causes of a Burning Smell:

Dust Accumulation: Over the spring and summer months, dust can accumulate on the heating components. When the heater is first turned on, this dust gets burnt off, producing a burning smell.

Foreign Objects: Sometimes small objects or even critters can find their way into your ducts. When heated, these objects can produce unpleasant odors.

Old, Dirty, Overdue Air Filters: Filters filled with dust, debris, and pet hair can sometimes cause a burnt smell when air passes through.

Motor Issues: The blower motor or its capacitor might be malfunctioning, leading to a smoky or burning smell.

Melted Components: Wires or plastic parts inside your heater can melt due to a malfunction or overheating, leading to a noticeable burning smell.

What Can The Average Homeowner Look For?

Before you call in the professionals, there are a few things you might consider checking:

Inspect Filters: Make sure your air filter is clean and replace it if needed.
Check Vents: Ensure that none of your vents are blocked or covered. This ensures efficient airflow.
Initial Start-Up: If it’s the first time you’re turning on your heater after a long while, the smell might be due to burning off accumulated dust. Usually, this should go away after a short while.
However, it’s essential to understand that identifying the root cause of this smell can be challenging. That’s where we come in!
