Split Type Aircon: Which is best?

[12vdc]

for some small window units it is ok. But im installing a window type. Magbubutas and all, id do the recommended installation.

Window or cabinet or cassette-type?

Most splits 1.5hp and below are corded, the outdoor unit is connected on the indoor unit' electric panel board. I guess since they are inverters, the sudden inrush current is prevented so they do not require heavy wires.
