AC Condensor Question

[Dead Parrot]

It is normal for the compressor to cycle on and off. Keeps the cold side from freezing up.

Also possible that you have either too much or too little refrigerant. 134 is less tolerant of improper refrigerant amounts compared to R12.

Some systems have a thermostatically controlled on/off anti-freeze switch in addition to the too low and too high pressure switches. If you have one of these, sometimes you can adjust it cooler while still not freezing up the system.
