Air Conditioning

The Air Conditioner is not always included in a ‘standard’ or log book service, so it can be easily neglected. In saying that, a regular vehicle service should always check for the more obvious faults which may be associated with an Air Conditioning system operating below expectations, such as:

• Drive Belt Tension
• Visible signs of refrigerant oil stains or the compressor, hoses, pipes or fittings.
• Loose or faulty compressor or equipment mounting brackets

Anything beyond this cursory inspection then requires a full Air Conditioning Service.

This will usually include the following as a guide:

• Inspection of drive belts and pulleys
• Check operation of valves and thermostats
• Inspection of hoses and components
• Evacuate system & recover refrigerant (weigh amount and record)
• Add required amount of refrigerant oil
• Charge system with recommended refrigerant type and capacity (if required)
• Condenser temperature check
• Suction line temperature reading
• Leak test system lines and components with an electronic leak detector
• Run vehicle to check air vent temperature and report

• Deodorize and sanitize system*
• Cleaning of condenser or radiator fins
• Any additional dismantling of other vehicle components in order to gain access
• Adjustment or replacement of drive belts and pulleys (may require component dismantling)
• Replacement of any valves, hoses, thermostats or other components as may be necessary
• Replacement of receiver drier filter if required
• Any additional or advanced diagnostic testing

* It is strongly recommended to thoroughly sanitize the cabin air ventilation system, using commercial grade steam cleaning equipment (as opposed to a simple vent spray). This helps to ensure the removal of harmful mould, bacteria and mildew that can build up in the vent and condenser cavities.
