Why a Furnace Smells Like It Is BURNING

A clogged filter will keep air from flowing freely, causing a furnace to run hot, emitting a burning odor, and creating a fire hazard.

When a homeowner turns on their furnace and smells smoke after a few minutes, there is cause for concern. When the smoke smell is associated with the furnace, the homeowner should investigate it immediately.

It may be as minor as a filter that needs to be changed or a significant fire hazard. Different burning odors can indicate different problems, and to be sure there is no safety issue, homeowners should contact their furnace service technician to inspect the system.

There are several reasons for a burning smell in conjunction with a furnace. Read on to learn more about what’s causing the burning smell.

Dirty air filter

A clogged filter will keep air from flowing freely, causing a furnace to run hot, emitting a burning odor, and creating a fire hazard. To prevent this from occurring, homeowners should begin each season with a new air filter.

A clean air filter will help cut down on dust in the home, preventing allergies from flaring up, keeping surfaces clean, and the air in the home from becoming stale-smelling or musty. A clean furnace air filter also helps the unit work more efficiently, lowering utility costs.

Dust in the furnace

After months of not being used, dust can accumulate inside the furnace. If a visual inspection does not reveal the source, there is a chance that it’s just dust. Although the dust will eventually burn off, it can leave behind a residue, which can catch fire. Seasonal inspections and maintenance by a licensed furnace service technician can keep the inner workings of a furnace free from dust, debris, and fire hazards.

Combustibles

Often, homeowners store numerous household items in the same area as the furnace. Many items, like kids’ toys, sports equipment, and seasonal decorations, can edge closer to the furnace’s pilot light, creating fire opportunities. Keep all combustible material away from the furnace to prevent a house fire. Always have a fire extinguisher nearby.

Problems with electrical components

If the smoke smells distinctly electrical, contact a furnace repair company immediately, as this could indicate a serious issue with the motor, heat exchanger, or other heating system components.

Clogged oil filter

An oil furnace can release a distinct oily odor when there are issues with a clogged oil filter. A licensed furnace repair technician can inspect the system and change the oil filter.

Anytime there is a smell of smoke when using a furnace, turn it off immediately. Inspect the area around the furnace to ensure there’s no fire. If the smell continues or becomes more pronounced after the furnace is shut off, get everyone out of the house and contact the fire department.

Upon inspection, if there is nothing unusual with the furnace, but the odor is still present when it’s engaged, contact a local furnace repair company for professional, reliable service.
