, posted Fri 6 Jun 13:23  
I HAVE A HOT WATER HEAT SYSTEM AND LOOKING TO REPLACE WITH A HIGH EFFICIENCY FORCED AIR FURNACE. I CURRENTLY HAVE CENTRAL AIR AND THE DUCT WORK IS ALL ABOVE IN THE ATTIC/RAFTERS. MY AIR EXCHANGE IS ACROSS THE HOUSE FROM WHERE THE FURNACE WOULD BE(35FT OR SO). CAN WE USE THE CURRENT DUCT WORK FOR THE NEW FURNACE(DUCT WORK IS INSULATED AND IN GREAT SHAPE) OR SHOULD WE INSTALL NEW ABOVE OR BELOW HOUSE(CRAWL SPACE)?
