Air Conditioning has the ability to reduce the in-car temperature to a comfortable level on hot days, no gale blowing through the open window, and the radio can be heard without it blasting out..!

By allowing all car windows to remain closed, even on the hottest days, the aerodynamics of the car remain at optimum, keeping fuel consumption low and exterior noise to a minimum, increasing safety to the driver and passengers.

The cleaner, fresher air with low Relative Humidity will enhance driver awareness and help prevent drowsiness

As aircon also conditions the air, the ability to remove the moisture from the air coming into the car on 'humid' days and to achieve a comfortable atmosphere within the car, perhaps in conjunction with the heater control - the AC button will control the Relative Humidity and the heater if needed will control the temperature leaving you free to enjoy the warmth without being stuffy. Very few cars are not able to utilise this extremely useful facility.

All the air coming into a car with aircon passes through a heat-exchanger, which as it is very cold, quickly becomes dripping with condensation, which collects and drains out under the car. Air entering this heat exchanger will contain dust and pollen grains, but by the time the air has passed through this heat-exchanger (called the evaporator) the vast majority of these pollutants will have been filtered out, trapped by the condensate and dripped back onto the road. It is estimated that approximately 80% of all dust and pollen is trapped in this way on each pass through the evaporator - this helps us all but is a source of particular relief to Hay Fever sufferers or Asthmatics.

Being caught in a long traffic jam on a hot day can be purgatory with all the exhaust fumes coming straight into your open windows, particularly if you are dressed for business - wet under the arms and hot under the collar- probably the time when you most wished that you had bought a car with aircon. This is when AC proves it is one of the neediest affordable luxuries.
