To keep your air conditioning system in peak performance, The system will require servicing every 12 – 18 months.
* We now service vehicles with air conditioning using the new R1234yf gas
These days, most new cars come with some form of air conditioning or climate control. These systems use a special gas to cool the air which in turn helps control the temperature within the vehicle. The system also dehumidifies and cleans the air.
Over a period of time the system can lose gas or become contaminated. also, filters gradually become saturated which can cause the system to become inefficient or fail completely.
As part of our vehicle service schedules, we will carry out a visual inspection of your air conditioning system and inform you when your vehicle is due a re-charge. To avoid costly repairs and complete system failure, we recommend that the system is serviced and recharged at least every 2 years. Contact us at your convenience for a temperature vent test, pressure test and visual inspection.
Part of the system is a receiver dryer, which has the following functions:
To filter out any impurities and therefore protect the compressor.
It contains a desiccant to absorb the small amounts of moisture that are present in the system. The system has a reservoir for excess liquid refrigerant.
An air conditioning service takes approximately 2 hours and consists of the Following
- Check pressures and vents
- Check temperature prior to service
- Check all controls including air distribution
- Analyse gas de-pressurise system, measure amount recovered
- Replace drier and o rings, add correct oil
- Visual check of condenser (clean with compressed air)
- Visual check of air con hoses (routing and condition)
- Visual check of compressor mounting brackets
- Visual check of compressor drive belt tension/condition
- Evacuate and re-charge system
- Check vent temperatures and pressures
- Check condenser fan operation
- Check all electrics and controls
- Check drainage tubes
COMMON AIR CONDTIONING PROBLEMS
- Air conditioning not cold enough
- The air conditioning system in your vehicle is not usually covered by most manufacturers’ service schedules and the refrigerant gas that is used to operate the system depletes over time. On average most vehicles lose up to 15% per annum, the problem can be caused when the system is not used during the winter months allowing the small ‘0’ ring seals to dry out resulting in a gradual deterioration in system performance.
- This will eventually result in the system to not operate at all.
- Air conditioning smells odd.
- If you notice any strange odours when you put on your air conditioning this could be signs of a bacterial build up in your system.
- As a system becomes older or used infrequently the air con system can develop bacteria, micro organisms and even mould or fungi growing in the system evaporator.
- This can lead to some very unpleasant odours. Some even claim this can result in headaches and flu like symptoms sometimes referred to as sick car syndrome.
- Air conditioning systems can be treated effectively with an antibacterial treatment that destroys the bacterial growth and leaves your car smelling fresh again.
