You need a load calculation to make sure the furnace is large enough to supply the new room. You can get it online from companies like DuctWork or go to local HVAC pros to get a load calculation worked out. Generally speaking, if the room existed when the house was completed, the furnace is probably powerful enough. If it is an addition that was added after the house was built, you may need a new furnace.
