Basic thermodynamics says it is not efficient to run the compressor to

switches work) This will mean the compressor runs more often but won't
work as hard when it does.

Agreed, that sounds like the winning approach.

In addition, you might consider adding air storage. That way it does
run longer when it runs, and runs less often.

Both of those are pretty simple, standard ways to approach the original
goal.
