What exactly do air duct cleaning people do? I see ads in the
newspaper
for $99 to clean typical forced-air homes, and it strikes me that they
can't do much for that.

Can one do it himself?

TIA

Also depends on what the ducts are made of. The newer homes with the plastic
spiral wrapped duct may not be able to be cleaned. The use a truck mounted
vacuum and a rotary brush. At least the ones I have seen.



When I cleaned ducts, it was an air brush. Imagine a thing plactic
tub running to a hard ball of plastic. the ball of plastic has ports
facing the tube, so when you run compressed air through it, it wants
to move away from you(the tube holder). It will self snake down the
duct and then you pull it out with the air on full blast. With that
pressured air and a large hepa filtered vacum sucking, you really get
a lot of junk out.

Use air since brushes can damage fiberglass and plastic ducts, and you
can dial up and down air pressure depending on what the duct material
is made of.
