Cold Air Registers Blowing Cold Air
Our cold air registers are blowing cold air worse than if the windows were open. The hot air registers blow cold air but not as forceful (maybe because they are 1/3 the size of the returns) This only happens when the furnace is off and we are heating with the wood stoves. We have metal ducting in the basement, our furnace is a Heil forced air using LP and is about 15 years old. Our first floor is the problem area. The second floor has a wood stove but only two registers, one in each of two of the three bedrooms. No cold air returns upstairs.
This is the first year we have noticed this problem and have been burning the wood stoves for over 20 years. Other than closing off the returns what else could we do? Closing or coverning the registers seems to help BUT we have to remember to clear them before we go to bed, the fires are usually still burning and we end up pumping cold air in again.
Anybody else have this problem?
