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.

The message was a little confused, so I might be off base here. There are
two air supplies in your furnace. One supplies air to the house and the
other supplies air to the burner. You don't want your burner to be sucking
air from the vents and a lot of times the intake vent draws directly from
the outside.

Why is it sucking air from the garage. This is dangerous. If there is a gas
leakage the gasoline fumes can be drawn into the furnace and could cause a
fire. The walls and ceiling between the house and the garage are supposed to
be protected by a 1 hour rated firewall to slow any garage fire from
spreading into the house.

If you have gas or oil, you are "sucking" air into the furnace
room to support combustion and carry the fumes up the chimney.
When running, a combustion furnace attempts to pull a vacuum on the
whole house.

The fact that your furnace panel doesn't seal well doesn't affect that
whole house vacuum. It merely allows the furnace to draw air from the
furnace room and distribute it through the registers.

Building codes demand that garages be constructed to prevent garage
air from entering the house (when any connecting door is closed of
course). If you somehow know that "dirty garage air" is entering
your house, then you have a problem with the doors and walls, not
the furnace.

In any case, around here, outside air is "dirtier" than garage air.

You can seal the gaps in the panel if you wish. That will improve
the ability of your system to heat the upstairs rooms.

So far as safety is concerned (avoiding risks of

building permits are issued for your locality.

is required by insurance firms in some places.)

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.

This is interesting. My garage is attached. My furnace is in my basement
which sort of borders the garage but not under it of course. I have a CO
detector in the basement which is mounted on the wall that sort of borders
the garage. If I run a car in the garage with the exhaust facing in,
within 2 minutes that CO detector will start sounding off. The basement
does not smell of fumes, but I am trusting the detector on this one.

So this would be a sign of poor construction? My house is only a few
years old. The return inside the house has a vent that exits the house on
the rear so I assume this is to equalize house pressure. So if any small
holes in my garage, then I assume air will suck in from there as well?


Thanks for any info.

Hello and thanks to everyone who responded. Yes, the furnace is in the
garage. Where would I be getting CO from? The furnace and water heater are
both vented through stove pipes going through the roof. Here are some
pictures I uploaded to illustrate better. Notice that the panel which
encloses the negative pressure area does not seal well around it. There are
no seals!

Are you sure that the dust is not something else, like clothes dryer
lint?

A customer of mine thought he had a giant dust problem, but when I
looked at the "dust" and saw that it was thicker than regular dust, I
matched it to clothes dryer lint. His dryer vent was clogged and the
furnace was sucking up the lint that could not be exhausted out of the
house and depositing it everywhere.
Check your clothes dryer vent.

The lack of a 100% seal is unimportant. The capacity to harm
is what's important. All furnaces as far as I know are similar to
yours in that the access door seals good enough.

Building codes demand that garages be constructed to prevent garage air
from entering the house (when any connecting door is closed of course).

Where are you? In most areas of North America, furnaces that heat houses are
illegal in garages because of the possibility of carbon monoxide and
gasoline fumes from the cars, and the inability to provide a one hour
firebreak between the garage and the house.

Admittedly our ranch house was built about 57 years ago, but it had a
gas furnace in the garage.

I'd like to know who runs a car in the garage. You don't have to have
a furnace there. What about the people who are actually in the garage
for one reason or another.

I turn the car off as soon as I'm in the garage, 4 or 5 seconds, and
the big door is open longer than that.

Warming up the car isn't really necessary (unless maybe it's a new
car?) but I certainly wouldn't do that in the garage either, since I'd
be sitting right there in the car in the garage.

As to the OP, I never figured out where we were talking about until I
saw the pictures you list below. I'm sure there is dust there, but
why do you think it is entering your house. That is not where the
house air comes from. It comes from a heating duct that comes from
someplace in your house. It recirculates the same air, minus and plus
whatever is lost and regained through doors, windows, and cracks
around the window glass, the door frames, etc.

The cover is just there to make it look nice. The springy part so it
doesn't rattle. Heck, I haven't had the cover on for years.

The air for the fire does come in through there, but the fire is
separated from the air that circulates though your house by the heat
exchanger.

Actually my furnace and CO detector is in the basement. There is no door
in that area. But there are some wires that run from the garage into the
basement since house is about 2 feet higher than the garage, those 2 feet
are in the basement ceiling area. So the sprinkler controls in the garage
have the wiring going into the basement. Maybe I need to seal that hole
tighter or something.

I have a relative that lives in Atlanta. Her home is no more than 10
years old in my estimation. The furnace is also in the garage. So is the
hot water heater. The kitchen and other areas are over the garage as well.


I don't think his furnace should be sucking dust from the garage though.
If his furnace filter is covered with dust from the garage, that is an
indication that the air to the house is coming from the wrong place.

Why would air or CO in the garage, that is mixed with oil or gas and

meant to separate combustion air from house air?
