Leak detection in air-conditioning systems
Here you will find useful information and handy tips relating to leak detection in automotive air-conditioning systems.
Important safety note
One of the most frequent causes of functional problems in the air-conditioning system are leaks in the refrigerant circuit. These lead to an unnoticed drop in filling level and thus to a reduction in performance or even complete failure. As far as refrigerant R134a is concerned in particular, it is well known that it diffuses out of rubber pipes and connections. Since air conditioning experts cannot be sure whether there is a leak or whether the refrigerant loss is the normal loss over time, careful leak detection is a must.
