What do hoses and lines do?

Hoses and lines connect the elements of the air conditioning system. Hoses are flexible. Lines are hard. There are generally three main types of hoses & lines: Liquid hoses & lines, Suction hoses, and Discharge hoses. Liquid hoses & lines connect between the condenser and the expansion valve on the evaporator. Suction hoses connect the Compressor to the Evaporator. Discharge hoses connect the Compressor to the Condenser.

Why replace or restore my hoses & lines?

The air conditioning hoses & lines are the most common-wear items in the system and one of the first components to leak. Hose & line failure is as a result of many things, including normal system wear, system neglect such as not changing the filter-drier and extreme engine compartment temperatures. When converting to 134a, it is essential to change all rubber hoses to barrier hoses. More on Converting to 134a!
