No matter what the temperature is outside, your home’s HVAC system is essential for temperature control and keeping your home comfortable. Part of good HVAC ownership is paying attention to any unusual behaviour or performance issues and contacting a professional when you notice something is wrong. A burning smell from AC vents could be a sign something is amiss.
What Causes a Burning Smell From AC Vents?
If you notice a burning smell coming from your AC vents there could be many causes. Some of these are harmless, but a burning smell from your air conditioner vents can also be a sign of maintenance or repair needs.
Burning Off Dust
If you turn on your home’s heat and notice a burning smell, this could be just dust that is being burnt off due to a lack of use during the warmer parts of the year. This smell normally goes away in a few minutes or a few hours. This should only occur a few times and should not be a common event. Also note that this only occurs when running the heat, not when cooling your home.
Overheating
Burning smells can also be a sign your furnace is overheating when running. This can be caused by issues such as a clogged air filter reducing airflow or issues with the furnace itself, such as the motor.
Electrical Problems with Your HVAC System
Burning can also be a sign of electrical problems with your HVAC system, such as damage to the wiring (tears or fraying) or damage to various related electrical components.
