Your perception is entirely wrong. Too much air flow can impede
performance rather then enhance it.

That's a function of the fan speed and blower size. Generally the more
air you can push per unit time, the more efficient you can make the
system (increased ability to transfer heat from the exchanger or to the
AC coil).

But too much is no good either. You need balance and there are curves on
the optimum residence time needed for heat transfer to take place. Very
slow air movement gains a bit temperature change, but at the expense of
proper circulation.

In any case, dust bunnies, pet hair, pollen can build up on evaporator
coils and make the unit pretty useless.
