Insufficient refrigerating capacity of air conditioner

Improper functioning of air conditioner may be caused by the following reasons:

Possible reasons / Suggestions

  1. Malfunction may be caused by insufficient amount of cooling agent in air system. It is advised to refill the cooling agent of the air conditioning system with XADO oil R-134a or pure cooling agent XADO R-134a. If there is a leakage in the compressors seals, they need to be replaced.
  2. Reduced pressure in the system may occur due to worn parts of the compressor. It is recommended to add XADO A/C revitalizant into the air- conditioning system.
  3. Contamination of the conditioner’s radiator may also lead to malfunction of the air conditioning system. In this case you should clean the radiator by using Verylube Engine compartment cleaner.
  4. Another possible reason is contamination of the compartment filter. In such case you should replace it.
  5. Improper functioning of the additional ventilating blower may also cause this problem.


It is advised to use a test-connector in order to refill or fill compressor.
