Why does A/C cycle?

To the original poster:
You can't just "dump a can of R134A in" and hope that anything good is going to come of that act.

They cycle when the evap coil temp gets right above freezing for optimal performance. If the thing doesent cycle correctly, (short cycling) chances are that there is a leak ie. not enough refrigerant to compress, back pressure dives too quick and gives a short cycle. Or the other way around, might be overcharged (too much refrigerant to compress, floodes accumulator, or a restriction) but its easy to charge most Yotas thanks to the good ol' sight glass "when the bubbles quit, quit charging and you are good to go!"
But remember, when charging 134a you gotta charge it in a liquid state because its a blended refrigerant.

lots of good info stated above. if its blowing good cold air, on a warm day, it should cycle on and off. on the real hot days is may not cycle, since its working so hard to cool. if its only blowing cool air and cycling, its probably low. the low pressure switch is shutting the compressor down.
