. It helps it to work properly and cool down the cabin air. However, there may be chances that the compressor will either short cycle or keep running all the time.
What causes car AC compressor to cycle on and off?
A few common causes of this problem include:
Improper Refrigerant Charge
– If there's too much or too little refrigerant in the system, the compressor may shut off randomly and prematurely. Dirty Condenser Coils – When condenser coils get clogged with dirt, dust and debris, compressors sometimes cycle off too quickly.
How long should a car AC compressor cycle?
When everything is working correctly, vehicle air conditioners cycle about every
15 to 20 minutes
. This varies by car model and compressor model, but this time decreases when the outside temperature is high, as the system must work harder to compensate.

How long should AC Stay off between cycles?
Conclusion. ACs should stay off for about
15 to 20 minutes
between cycles.

.
Why does my AC compressor shut off after 2 3 minutes?
The unit has been overheated
Once it has reached a dangerous temperature, the unit shall turn off to increase its longevity and avoid a power-cut. Since sludge or grime buildup is not uncommon in cooling systems, the compressor should be cleaned with a dry cloth at the earliest to keep it from breaking down completely.
