Home air conditioning systems come in several types, ranging from large central systems driven by outdoor compressors to small plug-in units that stand on the floor or mount in a window. No matter what form they take, air conditioning systems have similar working components, including a refrigerant, a compressor, a condenser, an expansion valve, and an evaporator coil. All of these work together to transfer heat and moisture from the inside of your home to the outside.
