This could be bad pressure switch,or ac clutch is going bad,if the correct amount of freon is in it,and not to much,or to less.

Assuming freon level is correct, those are the possible problems? Any other way to test?

One more thing you can check ,the is AC relay,if it is bad it can cause the ac to kick in and out all so,

You can take plastic cover off relay,hold the points together,if ac runs while you hold points together for a while,it will be the relay or pressure switch.
