I recently purchased a house which has 2 zone heating and cooling. Zone 1 is fine, furnace located in basement, AC unit outside, servicing basement and 1st floor. The Zone 2 is the issue, the AC is fine located outside but the furnace is in attic and ducts 'snaking' all over the attic. It services only second floor which has all the bedrooms. What I can do to get my attic space back, should I 're-snake' the ducts and re-position the furnace OR is there any other alternative? Thanks for the suggestions.
