If you have your system inspected and cleaned annually it should run without any trouble.

Central air blower fan not working. A capacitor stores up energy that provides power to your air conditioner s fans. On one side the fan blade draws in outside air o ver the condensing coil to dissipate the heat. The unit stops working. 5 common reasons why your central air conditioner fan is not working.

A kinked refrigerant line or a blower fan that isn t running right can cause this too. When the blades are covered with an excessive amount of dust or the blower motor is broken you will have issues with your system.

The blower motor starts turning fan blades that circulate cold air from the evaporator coils through the home s ductwork and into each room. The condenser lines should be cold and the air inside the home should be cool.
