What is an AC High Pressure Hose?

Your car’s AC system is divided into two portions: the low-pressure side and the high-pressure side. The low-pressure side includes everything between the system restriction (either an orifice tube or expansion valve) and the compressor. On the other hand, the high-pressure side includes everything between the compressor and the restriction.

Metal lines and rubber hoses connect the components within the AC system. Refrigerant travels through this maze of tubing. Often, the hose between the compressor and condenser is referred to as the high-pressure, or discharge, hose.

Symptoms of a failing AC High Pressure Hose

AC doesn’t work

Is your AC system blowing warm air? Then you may have a leaking AC high-pressure hose. If enough refrigerant escapes from the hose, the AC system will cease to work properly.

Refrigerant leaks

If you’ve got a really good eye – or professional test equipment – you may be able to spot a refrigerant leak at the AC high-pressure hose. In some instances, there may be either green-colored trace dye or a build-up of PAG oil near the leak. What you can see depends on the severity of the leak and whether your car has dye added to its AC system.
