dust and my furnace

am in desperate need for advice about my basement woodshop and the
furnace/central air unit. we share the same space, with no separation.
the local utility guy just told me on the phone that my options are as
follows, or I will kill the unit ...

1) Turn off the unit while working (freeze the family.) at the end of
the session, open the front, vacuum it out and the area immediately
around it before turning it back on.

2) Box in the unit and figure out someway to supply air.

a) new outside air supply? sounds expensive.
b) louvered opening in the ``wall'' that backs on to the
laundry room? (lint issues, but obviously much less than sawdust.)
c) cut the access door, with louvers, in the laundry room
wall, which would elimate the workspace used by SWMBO for her jewelery
hobby.

what do all you guys do about this?

REALLY want to avoid having to move to the garage ...

TIA

Possibly you were on the right track...how about making a box to attach to
the furnace that holds an air filter AND has its own blower to draw air
through this secondary filter? That way you won't add any stress to the
furnace as long as you draw sufficient air.

when I was a kid my grandfather use to have a shop in our basement (10 feet
from the furnace) and worked at least 4 or 5 days a week in the shop. There
was no dust collection system. That furnace was finally replaced 25 years
later

We had to add a combustion air intake when we put a new furnace in here
3 years ago.

Punched a hole in the outside wall and add a vent, then added insulated
(it's freaking cold here in the winter) flexible hose that runs between
the joists and drops to floor level behind the furnace.

It was done as part of the install so I don't know cost, but the
toughest part was punching through the wall as there was concrete
between the 2 x 12s.

I can take a couple of pics if you want to see detail, but it'll have
to wait to Friday as I'm travelling tomorrow.

Could you make cheese cloth filters to place over any openings and then
clean the cheesecloth once in awhile?

I guess I'm confused as to why it would kill the unit. For years I shared
the same space. Gas furnace. Conditioned intake air for duct work comes
thru a filter. Yes it has to be replaced more often. Firebox air goes
out the flu. I would think any fine particulate would burn. They are
seperated by a heat exchanger. What am I missing.

Although I've recently replaced my furnace with an enclosed unit using
outside air for combustion, my shop arrangements have been the same as
your for over 25 years. On the old furnace the cold air return was
directly ducted to the furnace. The only air draw from the shop was for
combustion.

I dealt with the problem by:

1. Using quality filters changed twice during each heating season.
2. Vacuuming out the filter at least once a month (more often when
extensive work was being done).
3. Vacuum out the combustion chamber at the beginning and end of each
heating season.
With A/C since the unit would run all year I would vacuum out the
cooling coils as well, performing the filter change and cleaning on a 3
month cycle, vacuuming the filter every month.

The old furnace I had didn't have A/C. It was installed in 1976 and
replaced 1n 2002. There was nothing wrong with the furnace but my wife
wanted A/C so being over 25 Y/O I thought it best to have it replaced.

well, I didn't see the inside of the unit, but apparently it was
packed with dust ... we noticed a definite performance issue with it
last night, hence the call to the service guy and the diagnosis ...
You got too much gunk in this thing.

I had duct taped an extra furnace filter to the front of the furnace,
but

1) it apparently did not block enough of the dust... and
2) the PSE&G guy said it was restricting air flow sufficiently to
be a problem in itself.

I would post this question on alt.hvac, or whatever it is called.

My 2 cents is that the furnace man was probably right, dust and burned dust
could foul it, but I really don't know.
