EZHangDoor,

Furnaces, unless they are the new high efficiency type, don't need fresh  air. Air yes, fresh no.

AND, the only reason high efficiency furnaces use fresh air is to eliminate the necessity of using heated air to go out the exhaust.

Kitepflyer, you are correct, that is why I recommended contacting a heating and cooling contractor. Maybe the doors and windows aren't the only thing lacking efficiency?
