The air conditioning goes off and on. Seems when it's particularly hot, it doesn't work, but this is not consistent. I've had it in for a check up 3 times. They are now considering the compressor.

Does it have to be blowing warm air (not working) in order for the problem to be discovered?

A good A/C tech can diagnose a problem with a 2 gauge charging station, pressure readings on the high and low side of the compressor will tell us a lot about what is going on, get this checked out first.
