We just moved into a 10 year old house with gas forced air heating. The carpet near my air vent returns are stained with a black residue. The air filter in furnace replaced and new carpets installed. The furnace technican doesn't know what is the cause of the black residue. Would the chimney needs cleaning? Thanks in advance.

The building I work in has water source heat pumps in individual apartments and we get black residue in the popcorn ceilings even after changing filters often.Could be a combination of air pollution and dirty duct work.

Burning candles caused dark "smudge" spots on our ceiling. (A textured ceiling installer told us it was mold. He was wrong.) Do you have dark areas on your ceilings as well? Candles might be the problem.
If your fireplace has been used, and you don't know when it was last cleaned, it's a good idea to get that done. Last time cost me $80 - a reasonable price for the peace of mind.
Another thing - dark residue can come from insulation that's breaking down in your heating/cooling equipment - or mold/mildew, but I would expect to see those around the vents, not the return.

I tend to type only 1/4 of my thoughts and therefore got us on the wrong track.I am figuring that gbchan meant his vents and not returns.My initial reply was to suggest that I have the same problem with a system that does not involve combustion.My vents are at ceilings thus blowing whatever the black stuff is in a 2 foot path from the vent along the ceiling similar to his carpet.Duct insulation deteriorating sounds like a possibility however,if you ever notice what builds up on fans that run alot it makes you wonder how bad our air really is!
