To Grizz.P,

How is ur usage going to be?
Planning to do 12k/9k/9k/9k
12k for the master bedroom which will be used every night.
The 2 9k units in the living/dining will be seldom used. Probably only when there are guests.
I think it will make more sense to just get the system 4 and 1 compressor. Worst case scenario is that it'll just take a little longer to cool up the whole house.

My other delimma is if I should retain the old piping (10 years old) that's running on r22 or shell out 2k to change to r410a (conceal piping)..
