R134A

Refilling your car’s air conditioning with R134a
A car air conditioner loses refrigerant over time, causing less cooling and sometimes strange noises.
Refilling is important and must be done only by a certified aircon specialist because the system is under high pressure and must be filled precisely.
Refilling it yourself is forbidden and can cause damage.
Prices usually start around €110.
Always have your aircon professionally checked and refilled.

Refilling car air conditioning with R134a: technical background
The car’s air conditioning system is a closed, pressurized circuit filled with R134a refrigerant and lubricating oil.
Over time, small leaks can cause refrigerant loss, resulting in reduced cooling capacity.
Low refrigerant levels can also cause cavitation, increased pressure differentials, and unusual noises in the compressor.
Refilling must be performed accurately by a certified specialist with calibrated equipment who also checks the system for leaks and adds the correct amount of oil.
Refilling by yourself is prohibited due to the risk of damage and safety hazards.
Costs start around €110
