A persistent burning odor when your HVAC system is running during the heating season may signal a more serious issue than the typical dust burn-off. A foreign object lodged near the furnace or in the air ducts can produce a noticeable burning plastic smell, which should never be ignored. Electrical burning smells are often linked to overheating wiring, malfunctioning components, or a failing motor within the furnace or blower assembly. Furnace repair may be necessary if the system continues to emit these odors, as prolonged operation under these conditions can damage internal parts or create a fire hazard. Inspecting the [...]
