Another vital job that your ac unit filter does is helps to keep dust from gathering on the evaporator coil of your air conditioning system. It is located inside the air handler, and is one of the 4 major components of any air conditioning system. The air filter is usually located somewhere just before the evaporator coil.
Any dust that travels through the filter ends up back in your living space, and can be very aggravating to allergy sufferers, and anybody else who is sensitive to dust. The filter also prevents the evaporator coil from becoming obstructed with dust, and decreasing the efficiency of the equipment.
This evaporator coil is very similar to the radiator in an automobile. Like your auto radiator, it will not be able to do its job without appropriate airflow. The reason Im comparing it to a car radiator is because most of us understand exactly what a radiator does, but, an evaporator coil works to cool air as it passes through Phoenix AZ Air Conditioning Repairs .
