I have a 2002 Trane XB1000 (exterior unit only, in storage since 2006) that I would like to use to add a/c to my approx 900s/f lake cottage. Are evaporators and coils and all parts needed still available to use w/ this 10 SEER unit? Is it worth it to purchase all the components, or just move up to a complete new 13 SEER system and sell the old unit on Craig's list. The cottage currently has no central a/c or heat. Thanks Ken.

Any 2 ton coil will work, just make sure you get a r-22 piston or a r-22 txv for the coil.
