That first time you flip on your furnace for the season and notice a burning smell—it can be unsettling. But don’t worry, this is a common experience with some clear explanations.
Here’s what might be causing that smell and when you should call in the pros.
Common Causes of Burning Smells
- Dust Burning Off — During the off-season, dust settles on your furnace’s heat exchanger and burners. When you turn the heat on, this dust burns off and causes a temporary smell. This usually fades within a few hours.
- Dirty Air Filters — Clogged filters can overheat your system, leading to a burning odor and potential damage.
- Electrical Issues — Burning plastic or rubber smells may indicate wiring problems, which require immediate attention.
- Mechanical Problems — Components like belts or motors can wear out and emit burning odors.
- Blocked Vents or Ducts — Restricting airflow can cause overheating and smells.
