Leak test
Vacuum and forming-gas test on the closed system, leak tracing with UV dye. We find the leak before any refrigerant goes in.

CAR AIR CONDITIONING · WAIDHOFEN
We do not top up blind. First the leak test, then the written finding, then your go-ahead. Refrigerant goes into the system only once it is clear that it will stay there.

SERVICES
An air-conditioning system loses up to ten per cent of its charge every year. Topping it up does not fix that, it only postpones it by one season.
Vacuum and forming-gas test on the closed system, leak tracing with UV dye. We find the leak before any refrigerant goes in.
Recovery, vacuum, drying and the exact charge specified by the manufacturer. Oil and dye only where they belong.
Fault memory read from the climate control unit, pressure curves on the high and low side, and the actual cooling output measured.
Function, control and noise under load. After compressor failure we flush the system, otherwise swarf travels through all of it.
From small hatchbacks to SUVs: better cooling at lower consumption, and a longer life for the system through regular service.
Steam cleaning of the air ducts against smell and germs, cabin filter to the manufacturer's spec.
REFRIGERANT
Since 1 January 2026 the EU charges a levy of €3 per tonne of CO₂ equivalent on fluorinated greenhouse gases. It hits the two refrigerants very differently.
Vehicles up to about 2017, and plenty of models beyond. Under quota, and rising in price for years.
Mandatory in new vehicles since 2017. Considerably dearer to buy than R134a, but barely touched by the levy.
That is why we bill refrigerant separately and by the quantity actually filled. You pay for what goes into your car, not a flat fee for the bottle.
HOW IT WORKS
Model, year and refrigerant type. If the type is unclear, we settle it from the chassis number.
You get the test price in writing first. Only then do we book a slot on the ramp for your car.
Tightness, pressure curve and vent temperature. The result is documented.
What is needed, what can wait, what it costs. Work starts once you say so.
PRICES
Refrigerant is billed by the quantity actually filled. Anything beyond the test comes to you as a binding quotation first.
A/C service R-134a, system flush and cabin filter change
Air-conditioning check, disinfection and cabin filter change
All prices include 19% VAT. Refrigerant is billed by actual fill quantity: €0.18 per gram of R-134a, €0.30 per gram of R-1234yf. Diagnostic work beyond the check is charged by time, always with your prior approval.
COMMON QUESTIONS
If your question is not here, call us. We will tell you honestly when the work is not worth it.
Every two years is the usual interval, regardless of mileage. Even a healthy system loses up to ten per cent of its refrigerant each year. If cooling drops off sooner, that is not a service item but a sign of a leak.
Because refrigerant is not consumed, it escapes. Top up only, and the system is empty again next season and you have paid twice. That is why we test for leaks first and fill afterwards.
Usually there is a sticker in the engine bay, often on the bonnet or near the radiator. Cars from 2017 onwards generally use R1234yf, older ones R134a. If in doubt we settle it from the chassis number before you drive over.
The check with a written finding takes about half an hour. A full service with recovery, vacuum and refill takes around an hour. Add a leak trace and you should allow more time.
Yes, and it is actually the better time. In spring every workshop is full; in winter you get an appointment sooner. The system should be run regularly in winter anyway, so the compressor stays lubricated.
No. The smell comes from moisture and germs in the evaporator and the air ducts, and has nothing to do with the refrigerant level. What helps is steam cleaning the air ducts, usually together with a new cabin filter.
