Air conditioning can greatly enhance the driving experience throughout the year as it both cools and dehumidifies the interior of the vehicle.
A common misconception is that the air conditioning system should be used in summertime only and switched off in cold weather. This is incorrect, as long periods of air conditioning non operation can cause the systems internal seals to deteriorate and eventually leak. Also, using the air conditioning in conjunction with the car’s heater in wintertime can de-humidify vehicle interiors rapidly in damp conditions.
Many drivers are alarmed to find water dripping from under the floor area and leaving pools of water under the vehicle when the air conditioning has been operating. This is a normal as it is the merely condensation dripping through a drain tube beneath evaporator.
For best results car windows should be kept closed while your air conditioning system is in operation. The air is drawn into the vehicles interior through a pollen filter. This will prevent any dust or allergens entering the cab.

The system comprises of a belt driven compressor which pumps a refrigerant gas called R134A through an evaporator, located in the interior heater casing. This is an eco friendly, non-explosive gas. When the heater blower is operated air is blown through the evaporator. This action chills and de-humidifies the air inside the vehicle. The gas then circulates through another radiator in front of the vehicle known as a condenser where it is cooled. Then the cycle begins again.

Benefits of regular servicing
Regular servicing of your air conditioning system will minimize condensation and dust within your vehicle. It also ensures that the hoses, joints and components of the system are inspected for any wear and tear. Failure to maintain your air conditioning system can result in unpleasant “mouldy” smells when you operate the system.
Air conditioning units can lose up to 15% of their refrigerant in a year. It is recommended to have a leakage test and air conditioning gas recharge carried out every 3 years to ensure maximum efficiency of the system.
