If you smell burning from your AC unit, you probably have an electrical problem. The burning smell can come from either a blower motor that overheated or a mechanical failure of some sort. This is due to the build up heat of plastic insulation on wires, causing melting and the burning smell in your unit. Also, if plastic, rubber, or other objects get caught in your ductwork, this can cause a burning smell. Even dirty air filters can overheat your AC unit, creating a burning smell.
