We follow the vehicle manufacturer’s recommendations and use only R134a as the replacement refrigerant for the older R12 refrigerant.  All new cars are R134a worldwide; due to its non-flammable ozone friendly properties and millions of hours of in-service testing in all climates.

The air-conditioning system in your car is a serviceable item, just as you have to change your oil and air filters from time to time.  It is very important to maintain your air-conditioning system for the following reasons:

  • Bacteria and Fungi and can grow in car air-conditioning systems and can cause allergic reactions such as hay-fever, skin irritations, runny noses and itchy eyes
  • Air-conditioning systems that are not maintained and serviced will put a strain on the compressor which can result in the compressor wearing out quickly if not serviced regularly. This can be costly, as it also increases fuel consumption and draws more engine power to run the system.

It is recommended that a vehicle’s air-conditioning system is checked and serviced every year to ensure it operates at maximum efficiency. However, there are some indicators that will help you determine if you have a problem with your air-conditioning system:

  • The interior takes longer to cool down
  • There’s a noticeable increase in fuel consumption
  • The windscreen doesn’t clear quickly

The air-conditioning system service includes:

  • Testing for leaks
  • Emptying and recharging the gas in the system.
  • Cleaning and Deodorizing the air-conditioning system

If you notice an odd, particularly musty smell in your car, it is more than likely the entire air-conditioning system needs proper cleaning with a de‑fungicide.  Our mechanics can provide a fungicide, please enquire about this service when booking an air-conditioning system service.

If you would like to know how your vehicle’s air-conditioning system operates, here’s how it works:

  • The refrigerant is contained under pressure in a Receiver/Dryer. The system must be recharged with refrigerant when a low level is indicated.
  • The refrigerated cold air passes through the evaporator where it mixes with warm air from inside the car. The refrigerant evaporates and absorbs the heat. The cooled and evaporated air is returned to the car and circulated via your blower.
  • The vaporized refrigerant, meantime, passes into the compressor where it is pressurized once more.
  • The pressurized refrigerant is forced into the condenser coils where the refrigerant condenses back into liquid form to repeat the cycle once more.
