AC minisplit (two condenser ((2x 24k) vs one condenser_48K with two branch boxes)

ductlessmini-split

I am trying to install A/C minisplit system with 6 zones.
However there is no space for the indoor branch boxes unless huge home improvements is done.
I was wondering if to install two condensers in small outside deck could be an alternative option. I would like to know it will work as efficient as "48K-two branch boxes". Huge innovation also costs a lot of money.

If you locate two mini-split condensers so close together that the hot air from one unit can drift into the other unit when the wind blows from a certain direction, that will reduce the efficiency. It would be better to separate the two condensers so hot air from one can dissipate before it reaches the other unit.

Also, try to locate condensers on the side of the house that is shady and cooler in the afternoon.
