Has anyone ever compared power usage between a swamp cooler and a small

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.

Thoughts?

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.

You must have different "real AC units". Mine won't run in
reverse. It's pretty much exactly like this:

Except it and the supply air ducts are located in the basement of my single-story house.

The simple insertion of a "reversing valve" turns an AC unit into a
heat pump. Not FEASIBLE on many units, but possible.

The technology is all there except for the valve.
