Fire departments in Middle Tennessee and North Alabama are advising residents that experiencing a burning smell when first activating their furnaces is a common occurrence. This scent typically arises from dust that has accumulated over the months of non-use and is now burning off. Generally, this odor should dissipate within a few minutes of operation.
However, if the smell persists or intensifies, it is crucial to turn off the heating system and seek assistance from a qualified HVAC technician. In situations where smoke is visible or there is a gas odor, it is imperative to contact emergency services by dialing 911 without delay. Residents are encouraged to prioritize their safety while ensuring their homes remain warm during the colder months.
