TIPS
How often should a vehicle conditioning system be inspected ?
As part of a vehicle's yearly service routine, a visual inspection of its air conditioning system should be carried out by a specialist engineer. The annual check up should include monitoring levels of refrigerant, pressures and temperature, checking refrigerant hoses, drive belts and wiring harnesses and changing pollen filters (where fitted).
Mobile Air strongly recommended that a full service is carried out two years and covers the following 11 stages:
- Recover all refrigerant from the system
- Remove and replace the filter unit
- Check condition of the condenser unit
- Check condition of all hoses and wiring harnesses
- Check compressor oil level
- Pressure test the system with Oxygen-free Nitrogen
- Vacuum system for a minimum of 30 minutes
- Recharge with R134A refrigerant and oil
- Leak test all components
- Carry out pressure and temperature test
- Update service records
What happens if a system is not regularly serviced?
Failure to have had a proper air conditioning service will cause an excessive build up of moisture within the system. All systems are fitted with a filter known as a receiver-drier or accumulator, which stores any moisture and contamination present in the system. If the filter is not changed then filter element will eventually break down and cause internal damage to the air conditioning system.
In certain cases when the air conditioning system is not operated on a regular basis, a pungent odour can be smelt within the car. This can also be cured with a microbiological treatment of the evaporator unit during the annual health check.
Do you need a licence to carry out service/repair to vehicle air conditioning systems?
New legislation released by the Department of Trade and Industry (EC Regulation 2037/200) states that by 31st December 2001 it will be mandatory for all air conditioning engineers to hold a minimum qualification level for servicing and maintaining equipment and handling of refrigerants. This qualification can be obtained by courses registered by the CITB or the City and Guilds.
