What are the components of the ac system?

An air conditioning (AC) system typically consists of four main components: the compressor, which pumps the refrigerant and raises its pressure; the condenser, where the refrigerant releases heat and turns from gas to liquid; the expansion valve, which reduces the refrigerant's pressure and allows it to expand; and the evaporator, where the refrigerant absorbs heat from the indoor air, cooling it. Together, these components work to circulate refrigerant and facilitate the heat exchange process that cools indoor spaces.
