Why Does My Furnace Smell Like Burning in Woodbury, IN?

Odd odors from a heating system sometimes require heating repair in Woodbury, IN, but other odors are normal. Why does my furnace smell like burning? Our team of experts can help you determine whether the burning odor is something that should concern you.

What Could a Burning Smell Mean in Woodbury, IN?

Because the heating season in Woodbury, IN, only involves part of the year, some burning smells from the furnace are normal. For example, burning odors commonly occur the first time the furnace kicks on in late autumn. Dust accumulates in the system all summer, and the furnace burns off this dust when it runs for the first time.

One way to avoid this issue is to have our team perform maintenance on your furnace in early autumn. We’ll clean the system and ensure all its components are ready to run during the primary heating season. Our work will reduce the impact of any burning odor from dust accumulation.

Burning smells in the middle of the heating season in Indiana could indicate a major problem. Try doing a filter replacement to see if that fixes the issue. If not, you might need a repair technician.

If a burning odor from the furnace causes concern for you at any time, it’s always best to call for help. Don’t sit around and worry about what is causing the issue. It will give you peace of mind to determine the cause and make any necessary repairs.

Smoky Odors Are Dangerous

Smoky odors related to furnace operation in Woodbury, IN, often occur with gas or oil furnaces or boilers.

The smoky smell often means that the furnace is not burning fuel efficiently or has a dirty filter. You might also have a blocked chimney or vent that does not allow the exhaust to exit the home. This problem could put your family’s health in danger.

If your furnace generates smoky smells, call our repair team right away. The problem might simply involve changing the filter. However, if it’s something more dangerous, our team can fix it quickly and give you normal furnace operation.

Even after we fix the issue, the smoky odors may linger if they are heavy enough. If you have smoky smells that simply won’t alleviate, you can take steps to remove a smoky odor from a home.

Metallic Burning Smells Need Inspection

Why does my furnace smell like burning metal or gunpowder? Overheating components could be to blame for this type of odor. If you don’t have a clean air filter at a time when the furnace works especially hard, you may have restricted airflow.

Temperatures in the Woodbury, IN, area rarely dip below 0 degrees, but such temperatures are possible during winters here. During these weather extremes, the furnace must work harder.

If the filter clogs, the blower motor won’t be able to move air efficiently. Debris in ductwork or blocked air vents could also cause an overheated blower motor. 

If it overheats, it could generate a metallic burning odor or an odor like burning gunpowder. Similar odors may occur when an overheated circuit board is failing.

Ignoring these odors and allowing excess heat to build up may cause the heat exchanger to crack. This could lead to carbon monoxide leaking inside the home. This poisonous gas can cause significant illness or fatalities if not caught quickly enough.

Melting Plastic Smells Could Indicate Electrical Wiring Issues

Regardless of whether you have a gas or electric furnace, all models have electrical wiring. If you smell odors that resemble melted plastic, you could have electrical wiring issues. 

Ignoring wiring issues could cause the system to break down. In some cases, you could end up with an electrical fire by not fixing this problem. 

Electrical wiring problems require the help of a licensed technician. Wiring exists in several different areas inside the furnace. You might not be able to find the area with the problem on your own.

A Burning Chemical Odor Might Be Normal for a New Furnace

Why does my furnace smell like burning chemicals? If you recently installed a new furnace, the issue could stem from the new product.

When manufacturers ship new furnaces, they apply coating and lubricants. These items will burn off when you begin running the furnace. You may need to run the furnace several times to eliminate these coatings fully.

If the burning chemical odors don’t become weaker over several days, reach out to our repair professionals. We can help you determine whether you should worry about the odors.

If You Have Rotten Egg Smells Instead of Burning Smells, You May Have a Gas Leak

If you have a natural gas furnace, a burning odor is not the only dangerous smell. If you smell rotten eggs or sulfur, this could indicate a natural gas leak. Gas companies add a chemical to create this odor, as natural gas itself is odorless.

Leave the house immediately if you suspect a gas leak from a rotten egg odor. Call first responders in Woodbury, IN, for help. You should also call the gas company and our team for service once your family is safe.
