A "Line Set" refers to the lines that run from the condenser unit in an air conditioning system to the cooling unit inside the house (this is where the blower is also located). There is always one large line, usually 1/2 inch, and a smaller line, usually 1/4inch. They are also insulated with a foam and will be cold once they are filled with freon.
