The air conditioning unit of a car is often easily overlookedthat is, until it malfunctions. And when it does, it is often too late for simple troubleshooting procedures. Unlike your household unit, your auto air conditioning unit is more complex. Your auto air conditioning unit is a system that functions much like your cardio-vascular system. The compressor is the heart that pumps a refrigerant called Freon throughout the air conditioning unit. Freon, a combination of gas and liquid, causes air to cool when compressed. Like your ordinary household air conditioning unit, your auto air conditioning system will not work as it should when Freon levels are low. Make sure you have a mechanic check Freon levels regularly before the unit experiences major breakdown. The ability of the Freon to carry heated air away and leave cool air behind depends on the pressure applied to it. Air coming into the condenser helps in this process. This is the reason why, sometimes, for older models of ar conditioners, the temperature is cooler when the car travels at full speed than when it stands idle. This allows the compressor to pump Freon harder and faster. Therefore, the air conditioner system operates much more efficiently. To keep the performance of the auto air conditioning unit running smoothly, and to prevent temperature changes, make sure that the electric cooling fan that takes in air functions properly. It must turn very fast for it to be effective. Motor overheating affects the functions of your auto air conditioner, as it does all the aspects of vehicle performance. When the motor is shot, the fan may not work as efficiently as it should. The added heat coming from the motor will also make it difficult for the air conditioner to cool the car. Make sure you take care of your motor. Always have water ready to cool your motor and prevent it from overheating. |
