Auto Air Conditioning FAQs Q: How often should a vehicle conditioning system be serviced? A: Your air conditioning system should be inspected every 18 months to 2 years or as required. This annual check should include a check of refrigerant quantity, pressure and temperature, checking refrigerant hoses, drive belts and wiring harnesses and changing pollen filters. We strongly recommend that a full service is carried out every two years; in addition to the above items the filter/dryer is changed. Q: What happens if a system is not regularly serviced? A: If an aircon system is not serviced, a build-up of moisture will occur. The built-in filter (receiver-drier or accumulator), is designed to store any moisture and contamination present in the system. If the filter is not changed then its element will eventually break down and cause internal damage to the air conditioning system. Q: Why can I smell a 'musty' smell inside the car when I turn on the aircon? A: This is due to the build-up of mould and microbes on the evaporator. It can be cured with a microbiological treatment of the evaporator unit during the annual health check. Q: Is there anything I can do to keep the aircon working? A: On a modern vehicle, the best advice is to run the air conditioning continuously. Modern systems are efficient and will not add greatly to the fuel consumption. Continuous running ensures that the refrigerant and oil are circulated throughout the system, keeping the seals lubricated and preventing microbe build-up on the evaporator. |
