Although central air conditioners differ from model to model, they operate on similar principles. Now, I’m gonna address, is central AC worth it? As well as potential problems you may encounter included among the components that make up. 

A central air conditioning system is a condensing unit which is located outside the home. The condensing unit contains the air conditioner condenser coils, the compressor, and the condenser fan motor.

The evaporator coils or cooling coils are located inside the home and are mounted on the top of a furnace or air handler. The furnace or the air handler fan uses a circulation blower fan to draw air through the returned vent.

The room air is then drawn back through the return and the airflow cycle continues. Once the room air is cooled sufficiently, the wall thermostat signals the circulation blower fan and a condensing unit to turn off until the room temperature increases.

The temperature in the home is regulated by the wall thermostat. The thermostat can be powered by the furnace control board or by batteries. The thermostat must be in a central location in the home, positioned at eye level and away from direct sunlight for proper temperature regulation.

So, Is Central AC Worth It? 

The most important factor in efficient operation is airflow. To ensure proper airflow, the air filter should be checked monthly and replaced as needed. There are several types of filters available and range from 1 to  5 inches thick. The filter can be installed into the slot in the return or an air cleaner. 

Some homes will have an electronic air filter that is powered by the furnace or air handler control board. When the circulation blower fan turns on, the blower fan motor can run at multiple speeds to improve efficiency. Lower speeds are used when the furnace is heating and higher speeds are used for air conditioning. 

If the circulation blower fan becomes noisy during use, the set screw on the blower wheel may have loosened causing the wheel to wobble on the motor shaft. You can fix this problem by tightening or replacing the screw altogether.

Having all these features, the air conditioning system has some pros and cons individually. If I generally say, yeah, central AC is worth it. But you may know it’s pros and cons to be finally sure for your specific needs.
