It sounds as if there is too much air gap in the clutch itself (common in highly mileage systems) but not to be confused with an over charge or high line pressure.
Just to be sure its the compressor clutch, jump the pins on the ac cycling switch. Notice if the clutch engages or does not. If it does engage every time when jumping the cycling switch then you can rule out the clutch. If it does not engage, try tapping with a hammer or long rod, if the clutch then engages then you have too much air gap.
Replacing the clutches is fairly easy. If it's something you decide to to, post back and I will get you the service instructions.
