Why? Using an oversize evaporator & air handler should not be a problem,
and will actually be slightly more efficient overall. Of course you'll only
get 1.5 tons of cooling, so the real question is whether that is enough for
your situation. Think of it as a 45hp motor in your VW bug, instead of a 60

Again, why? Basically everything that wears out (compressor, fan, etc) can
be replaced. Unless the coils are damaged, you should be able to keep it
going nearly forever.

Not even totally banned then, only not allowed to manufacture new
refrigerant. Existing supplies can continue to be recycled until they leak
