Central Air Handler in Basement?
In a few years we'll have to put in a new hot water boiler and central ac. Both systems are very old. we'll probably add an ERV into the AC mix, and foam the attic eaves and walls and rim joists; already have blowin in insulation in walls.
In order to free up floor space in the attic from the air handler and ducts currently all over the floor, we'd like to move the AC to the basement and use the inside chimney--which will then be empty since we'll direct vent the new boiler--for the AC ducts. (boiler's already in basement.)
Does this make sense? we really could use that attic space.
