Refrigerant lines
Copper pipes that connect the outdoor condenser unit to the indoor evaporator coil in an HVAC system. These lines consist of two separate pipes: a larger one called the suction line, which carries low-pressure refrigerant gas back to the outdoor unit, and a smaller one called the liquid line, which carries high-pressure liquid refrigerant to the indoor coil. Together, these lines enable the transfer of heat, allowing the system to cool or heat your home effectively.
