A. You left your car running in the driveway and you're smelling car exhaust. 10%
B. Your tech cleaned the air handler coils and left some cleaner on it, which will shortly blow off. 2%.
C. You have a plugged condensate drain causing wet coils and mold growth. 88% chance. When the drain pan fills it should trigger the safety switch.
