Heating System Odors – What’s that smell?

Smoke or Burning Smell

The odor of burning wires, plastic insulation, or other material inside the system could indicate overheating. The smell (and worse, the sight) of smoke could indicate severe overheating or even a fire. Shut the system off until the source of the odor is located by your HVAC professional.

Electrical “ozone” Smell

This odor can indicate overheating as well as problems with motors, wiring, or electrical components. It can indicate the pending failure of a blower motor. Again, the system should be shut down and the problem fixed as soon as possible.

Burning Dust Smell

This odor is common when heating systems are first started after being idle over the summer. Dust that accumulates on system components could get hot when the system operates and cause this smell. It will usually stop within a few cycles of the heating system.

Dead Animal Smell

It is possible for small animals such as roof rats or squirrels to get into the heating system or ductwork and die, producing a carrion odor. The smell should go away once the dead animal is found and removed.
