Environmentally Friendly Practices
For older vehicles using R12 refrigerant, containing ozone-depleting CFCs, it’s crucial to maintain proper sealing to prevent harmful emissions. Running the air conditioner for five minutes weekly helps keep seals hydrated and functional.
Modern cars benefit from the use of R134a refrigerant, which is significantly less damaging to the environment. Whether your car uses R12 or R134a, we’re equipped to handle it all responsibly.

Car Air Conditioning – FAQs

We recommend having your air conditioning system checked every 12 months. Regular servicing helps keep the system running efficiently, prevents costly repairs, and ensures it performs well through every season.

If you notice weak airflow, warm air when the AC is on, or unusual noises, it could be time for a regas. A musty smell or foggy windows may also indicate low refrigerant levels or a system leak.

A standard air conditioning service usually takes between 1 to 2 hours, depending on the condition of your system and whether repairs are needed.

Our comprehensive service includes refrigerant regas, leak detection, compressor and condenser checks, airflow and temperature testing, and cabin filter replacement if needed.

We specialise in European vehicles like BMW, Audi, Mercedes-Benz, Volkswagen and more, but we also service a wide range of other makes and models.

Karl Knudsen Automotive Chatswood will complete a full air conditioning evaluation of your car’s air conditioning system and quote any repairs required. When performing a system leak test and assessment, fresh gas with a lubricating oil is used, before a final system diagnosis is conducted.

Our team of professional mechanics will investigate operating pressures, leaks, breakdown or hose damage, seals and components. The drive-belt tension is checked and the entire system recharged with a refrigerant.

For older cars, the air conditioning system often uses a refrigerant called R12 containing fluorocarbons (CFCs). It is important to run the car air conditioner for up to five minutes every seven days to stop the system seals from losing moisture and drying out so that ozone-depleting substances are not released into the atmosphere. Modern cars use a CFC free refrigerant known as R134a which is far less damaging to the environment.
Your car air conditioner requires periodic servicing to make sure that its operation is effective and efficient. Karl Knudsen Automotive Chatswood can repair or service your air conditioner, and a regassing service is available.

Regular air conditioner servicing ensures your car’s air conditioner is functioning at the required temperature, to ensure your car stays cool in summer and demisted in winter. Car air conditioning systems need a disinfectant regularly to stop mouldy smells. To effectively eliminate mildew and fungi you should have your air conditioner disinfected regularly.
