Has anyone ever compared power usage between a swamp cooler and a small
window A/C? I suspect the A/C uses a bit more power. or is it significantly
more? It would be a lot more convenient than a cooler. There seem to be a
lot of water pump, fan belt, pad water distribution and other problems with
a cooler despite decades of using one.
It wouldn't matter to me which was more efficient. A swamp cooler is a pretend AC unit. It evaporates water, therefore humidifying the room. Also a real AC unit can run in reverse and serve as a heat pump for winter.

Why on earth could an AC unit not run backwards? You just reverse the pump. Every one I've seen in the UK (commercial and home) has been able to do this. The controller usually has settings for heating, cooling, or automatic. On automatic you can simply set a range (say 18 - 22C) and if it goes over, it cools, if it goes under, it heats.

operate in heat/cool mode.
and the pump is NOT reversed. There is just a rather complex little
device called a "reversing valve" which switches the high and low side
of the compressor between the "evaporator" and the "condenser" -
making them trade places and functions.

For most of us, no need. We only use cooling here for two months. We
have very efficient central heat and the AC goes into a window in the
summer for cooling only. It can also get very cold here.
In more mild areas, central AC with heat pump is common and works well.
What you're describing is what is referred to a split unit system or
inverter. After screwing around with a through the wall A/C unit which
was noisier than all get out in the size needed to cool the addition, I
finally got smart and picked up a split system (air handler inside,
compressor/inverter outside). What a difference. Very quiet (hard to
tell it's running, actually), and much cheaper than our old A/C unit.
And, as you say, when heat is needed, the system reverses itself and
heats the interior drawing heat from outside even when it's in the 20F
degree range outside.
