forced heat furnace blowing cool air

hello,

i have a forced air heater and i read alot about them and tried to understand as much as i could. i know they include a cool air register. my register is on the floor in the hallway of 3 bedrooms, but i understand its supposed to suck air, not blow air. there is another register towards the bottom of my living room wall ( i think its a register) it blows cool air too. unit was already there when i moved in. i found out it was installed december 2001. per model number its a 1999 unit. fueled with natural gas.

the other vents, they are high on the walls, and blow warm air. checked filter and cleaned it. any ideas, or would this be normal fucntioning of a forced air heater.

thanks for any replies.

You may have two return air registers. That would not be unusual.

If they are actually OUTPUTTING cold air when the heat is running...that would be unusual. They should be sucking in room temp air.

I think you might need to trace the actual ducting back and make sure they are connected properly. If one duct has come loose it may be sucking attic or crawlspace air somehow?
