QUESTION:Our new place has a 38 year old "floor furnace". I spent the better part of
one morning vacuuming and cleaning out 38 years of collected dog and cat fur
and a variety of other unrecognizable objects that have fallen through the
grating, including some pretty nifty things too that I'll bet the previous
owners were sore to lose. We're talking about 6 or 8 inches deep of this
stuff.
But, when the furnace fires up the rising heat still smells "dusty" and makes
it difficult to breathe, at least until it gets going good.
What can I do to help alleviate this?
ANSWER: Seriously consider getting a trusted tech out to go over top to bottom. Most
of the infloor units that are that old that we see around here have bigger
problems than just dust...most have a heat exchanger thats starting, or has,
cracked. I assume its oil fired and you REALLY need to have the ignition
rods checked, and a new nozzle put it. After that, the tech will need to
adjust the heat rise if such a provision is there, and check the burner
motor and shaft for the pump...
A good tech will also make 100% sure that you have no CO entering the home,
and pull the blower and service it. While the smell may go away, its
possible to have other things wrong that in a unit that old you wont see
right away, and without the proper tools, you wont see until it fails.
Best advice is to get it gone over, correctly.
