I was in the attic near my furnace this weekendand there were two 3/4" pcv
pipes that came up next to the furnace that were blowing cold air into the
attic. It was coming out strong enough to feel it a foot above the pipe
ends.

The house was built in 2003 in Houston TX.


Is this normal?

PVC is often used to drain the condensate pan, and some cool air will
exit it if there is no trap in the line. Could this be what you felt???
More info needed.

It is, if the pipes are intended to supply combustion air to the
furnace rather than draw air from within the house.

Most likely condensate lines for the evaporator. My off the cuff
advice is to put a plastic bag over the top of each of them (sandwich
bag) and then a couple rubber bands over each bag.

Probably not a serious issue eithr way, but you'll feel better about
it.

Wouldn't combustion air, and exhaust be extended past the attic?

Sound like drain lines, maybe the OP can tell us the size, and if they
run down.

I looked again and one is coming from the furnace and only elbows up. The
other goes from the furnace elbows up and has am insulator. wrapped around
it and goes down over the nearby bathroom.

You guys are probably right about consensation line but I wanted to make
sure.
