Condenser coils are also known as outdoor coils as they are a separate unit that is located outdoors. Its main function is to expel the heat that is absorbed from the air.
The evaporator unit is sometimes referred to as an indoor cooling unit. It is responsible for extracting the indoor heat and adding it to the refrigerant.
It contains a series of bent pipes and fins. The cool refrigerant travels through the unit, making it cool. Air blows across the cold unit and supplies the cool air to your rooms.
