I get a lot of dust in my house. I noticed the front panel on my
furnace is not even close to air tight. I can see through gaps and
holes directly into where the blower is (which is directly over the
air filter). So the blower is sucking in some air from the return
line and through the air filter, but a lot is coming through the gaps
in the panel. Should I somehow seal this panel better and force all
air to come from my air return vent which is located in the center
hallway of the house? I don't understand this design of a furnace
which takes no care in keeping dirty air from the garage out.

I don't like the idea of a furnace in a garage or sucking any air from
the garage. Combustible gases like gasoline and a furnace don't get along.
A garage often gets CO gas. You don't what the furnace getting any of that
so most if not all codes are not going to allow the furnace to be in the
garage. Also very important is the garage is a source of CO gas. CO is
poisonous and you don't want that sucked up into your home.

Dust is the last thing I would be worried about.
