I have a cape cod house that does not have duct work. The first floor is about 1000 sq. feet, the second floor is around 850. There is also a full unfinished basement.
I am planning to install conventional central air in the house. The second floor is undergoing renovation. There is no sheet rock and new insulation is yet to be installed. I am trying to figure out if
1) 1 unit can handle two floors or do I need two sets of everything installed?
2) Where should duct work and air handler be installed ? (attic and run down to the first floor, basement and run up to the second floor, or both).
