I have a house with forced air electric heat. Over the course of a year, a
sooty residue builds up on the walls and rugs seemingly coming from the
floor registers. Could the electric heating elements be burning off and
causing the residue? I'm tired of washing walls and cleaning carpets. If I
install a propane furnace would the same thing happen? I thought electric
heat was clean.
Side note: the ducts all appear to be clean. If I take off a register and
stick my hand down a duct, I do not get a sooty finger. They were
professional cleaned a few years ago in an attempt to resolve the problem
Do you smoke, do you have a good filter in it, Propane will cost less
to heat, gas even more. Id suggest you get a few better pros out ,
obviously the ones youve had didnt help you identify the source.
The soot is not coming from the heater, but rather it is in the house
already. Every house has dust and yours may be exaggerated a bit from some
other source. The heated air is just grabbing it and depositing it on the
walls. Changing fuels sources will not help, may hurt. The dust is in the
air and the velocity of the moving air deposits the reside on the nearest
surface, usually right at the registers, when the velocity drops, such as
coming out of a vent to an open area.
Smoking, lots of cooking will make the problem more. Burning candles adds
lots of soot in the house. Just look at the mound of burning was and how
much greasy smoke it gives off.
You need better filtration. If standard filters do not work, look into the
