Operation check
Temperature, pressure and overall system-behaviour checks.
Vehicle air-conditioning service
Weak cooling, unpleasant smells, noise and frequent cycling do not necessarily mean the same fault. The system should be checked first.

Services and situations
Temperature, pressure and overall system-behaviour checks.
Refilling only after checking the system and the required refrigerant type.
System checks when refrigerant is being lost.
Checking the cause of unpleasant smells and recommending the appropriate treatment.
What happens next
Say whether cooling is weak, the air is warm, there is noise or an unpleasant smell.
Temperature, pressure and behaviour indicate where the next check should focus.
A rapid loss may indicate a leak or failed component.
A refill, leak check and hygiene treatment do not solve the same problem.
Important before visiting
If cooling weakens again quickly, the system should be checked for leaks or a failed component.
