In an automobile’s air conditioning system, the hoses play a critical role in transporting refrigerant between components. The main types of auto air conditioner hoses are the following three:

  1. High-Pressure Hoses (or Discharge Hoses):
    • These hoses carry the refrigerant from the compressor to the condenser. Given that the refrigerant is in a high-pressure gaseous state at this point, these hoses need to be durable and able to handle this pressure.
  2. Low-Pressure Hoses (or Suction Hoses):
    • These transport refrigerant in its low-pressure state. Specifically, they usually carry the refrigerant from the evaporator back to the compressor. These hoses operate under less pressure than the discharge hoses but are equally essential.
  3. Liquid Lines:
    • These hoses transport the liquid refrigerant from the condenser to the evaporator or the expansion valve, depending on the A/C system’s design. While technically still under pressure, the refrigerant is in its liquid state at this point.

Each of these hoses is designed to fit the specific requirements of its function within the A/C system. When any of these hoses malfunction, leak, or get blocked, the efficiency and functionality of the entire air conditioning system can be compromised.
