A split system condensing unit is a type of air conditioning system that uses two separate units to cool a space. The first unit is the condensing unit, which is located outside the home or building and houses the compressor, condenser, and expansion valve. The second unit is the evaporator coil, which is located inside the home or building and contains the evaporator and blower. The two units are connected by refrigerant lines, which carry the refrigerant between the two units. The condensing unit works by compressing the refrigerant, which causes it to become hot and then releasing it into the evaporator coil. The evaporator coil then absorbs the heat from the air, cooling it down and releasing it back into the home or building. The split system condensing unit is an efficient and cost-effective way to cool a space, as it requires minimal maintenance and can be installed quickly and easily.
