Because of this inactivity, dust particles start collecting on the heat strips or heat exchanger. Once you finally turn on your heater, all that built up dust burns off, emitting the burning odor. This smell then gets sent through your duct system out your vents and into your entire home. This is generally a problem that will only happen once a year when you first turn on the heat for the fall and winter. However, if you want to prevent this unpleasant smell, don’t skip your fall Maintenance.
