[DIY] Digest Number 1388
We moved into a new home that has the air vent going to the furnace. I know that it is supposed to be there, but honestly, it brings in so much cold air. It feels like a window is open all the time. The duct work is about 5 feet long to reach the furnace and the opening at the end of the duct is 8" across. It is also just open...no screen on it or anything so I'm sure critters come through it all the time. (did I mention I hate spiders)? Is this normal and can you at least add more duct so it diminishes in size? Can you cap it off with screen or something to prevent things coming in? Any help would be appreciated. Joan
