A condensing unit is an essential component of any air conditioning system. It is the part of the system that actually cools the air and is usually located outside the home or building. The indoor condensing unit is the part of the system that is installed inside the home or building. It is responsible for collecting and removing the heat from the air, as well as for cooling the air and returning it to the living space. The indoor condensing unit typically consists of a compressor, a condenser coil, an evaporator coil, and a fan. The compressor compresses the refrigerant gas, which is then passed through the condenser coil. The condenser coil removes the heat from the refrigerant gas and passes it outside. The evaporator coil then absorbs the heat from the air and passes it back to the compressor. The fan then circulates the cooled air throughout the living space. The indoor condensing unit is an essential part of any air conditioning system and is responsible for providing a comfortable and cool living environment.
