My unit blows out black soot looking stuff, and it smears when touched, and my filter is clean. What is it? And how can I get it to stop?

Carol, the first thing I would suspect would be mold in the insulation within the blower compartment. Sometimes the cooling coil overflows, causing the fibreglas insulation to get wet which in turn allows mildew/mold to form in that compartment.

Severe cases will sometimes discharge nasty stuff as you describe coming out of the ducts.

Turn off the power and remove the blower compartment cover and investigate.

Seems like a black mold has invaded the air conditioner unit. What do I do and is it safe to run?

No it's not safe to run. It can be cleaned with a solution of 20% white vinegar and 80% water. Where rubber gloves when cleaning the unit.

Thanks for choosing FixYa.

Our frigidaire FAC10SPP1a4 air conditioner is emitting a very foul smell. What could be the problem?

Air conditioners work by taking the moisture out of the air, and that water is put in a drain pan. Sometimes, the dirt and pollen will grow mold on that water and cause a foul smell. Bleach will kill it.

Black flakes

Chances are what you are seeing is not mold, but deteriorated insulation from the inside of the unit being ejected out the air discharge.

You may need to partiallly disassemble the front of the unit and find the area where the insulation may be damaged. If it's badly deteriorated, it may need to be replaced. In some units, the insulation is glued. In others, it's clipped in.

If it's just bruised, then a small piece of metal screening (1/8" or 1/4" hardware cloth) can be placed and secured over the damaged area to prevent subsequent damage and the black flecks you are witnessing.

Black particles coming out of the room air conditioner

dirt, dust, or mold. could also be the tubing insulation flaking off. either way, open it up and clean it out. the dirt, dust, and flaking insulation can restrict air flow through the coils and cause the ac to not function properly. if it is mold, it's can cause sickness (legionaire's disease). do not use chemicals on the coils. it might be best to replace the ac alltogether. to prevent mold: when installing the ac, make sure the unit is slightly tipped towards the outside. any condensation that collects on the coils will drain out. failure to do so will result in water pooling inside, and this can cause mold.

Black mold growing on gray rubber boot inside door.

Leave washer door slightly ajar after use to air out any moisture. Should prevent any future mold.
