When changing my furnace filter I looked inside the cold air return
and noticed it was very dirty inside. I want to vacuum it out but the
filter slot is to small to get the hose of the vacuum in it. I was
wondering if I should cut an access hole in the sheet metal to get to
it. When I am done should I 1) just close the hole back up with sheet
metal and duct tape or 2) put a vent cover over it. The reason I was
thinking a vent cover might be a good idea is because the unit is
located in a utility room that has just the furnace and a hot water
heater and by putting a vent in there it might help circulate the
excess heat from the room into the rest of the house.

Unless the furnace has a sealed combustion unit that pulls the air in
from outside the house, putting a return air vent in the closet may
disrupt the natural combustion product flow or possibly pull
combustion products into the house.
Thanks for all of the responses. That is what I like about this news
group. What sounded like a good idea to me probably isn't. I think
I'll pass on the vent and just try removing a section to clean it.

In the furnaces I've installed, the cold air return "boot"
is installed with several sheet metal screws. It is likely
possible to remove the sheet metal, by removing several
screws. Several in the side of the furnace, and several
screws where the vertical pipe hooks to the horizontal duct
in the floor.
That would be easier than sheet metal work, and patching

If dirt in duct is before the filter leave it alone, a vent in the
utility room will probably make the water heater chimney suck in so it
will be venting burnt gas inside, it could affect the pilot light
also. Did you ever have a pro clean and check out everything. That
would be smartest. Your experimenting might be a disaster.

Unless you;re set on providing a larger access hole....
Try this, take one of those cardboard tubes from Xmas wrapping paper,
fit it to the vacuum hose. Squeeze it down in diameter, making an
oval of sorts. Seal the end with tape and cut a slot on the bottom
side of the now squeezed tube. This should allow you to suck up most
of the debris.
A vent is probably ok IF the combustion air doesn't come from that
They sell attachments for cleaner hoses that attach a small diameter
hose to the end of the normal one. That would be easier than doing
sheet metal work, and you would have a handy tool to use in cleaning
things like your computer (you would be surprised how much dirt
accumulates in there and interferes with cooling if you don't clean it
out. My wife got hers at an Oreck store; I'm sure other stores have
them, too. Or you could just tape a piece of tubing in place.
