I keep a pretty close eye on our central HVAC unit (located up in the
attic), and vacuum-clean the coils, check for leaks, etc. myself. The
last year or so, however, especially if it's been off for a day or two,
when it first comes on, little flakes of medium-brown paper, the
biggest about like the end of a pencil, come down from some of the
vents. Can anybody tell me what this is and where it might be coming
from? I can't see anything like that in the central unit.
Thanks,
Ron M.

pro??

sounds like a rodent or two has taken up residence in your duct
system, and the tiny little flakes of brown paper are the remnants of
their 'brown bag lunch special'
Nope?
maybe the cardboard duct system is finally deteriorating?
Nope?
maybe the little brown flakes are really rust flakes?
reminds me of a svc call I went on....
complaint: little tiny brown flakes of something lightly dusting the
tables in a restuarant. 20+ yr old lennox gas pkg unit on the roof
with the welded mild steel hx. Rust-bucket city. Rust was flaking
off the hx, blown thru the coil and on down the duct system, right out
onto the customers food. Yummy.

I have seen the algae/sludge buildup in the coil drain pan dry up and
turn into small flakes which can be blown out through the ducts. The
stuff is brownish color and could be mistaken for bits of paper, I
suppose. Larry
