What does a low side service port look like?
The low side service port is usually located between the AC compressor and evaporator. The low side service port will have a black or blue plastic cap that needs to be removed. The low side service port is the only port to which the AC Avalanche coupler will connect. Never charge through the high side port.
Which is the low side and the high side?
A semiconductor switch placed in the upper circuit with respect to an external load is referred to as high-side drive (power supply side), and when mounted in the lower circuit is called low side drive (ground side).
Which is the high side AC hose?
The high side, or discharge line, will be the line connected to the compressor from the bottom or lower position. It will not be wrapped in insulation and will be warm to the touch.
Is the liquid line the high side?
The high side, or discharge line, will be the line connected to the compressor from the bottom or lower position. It will not be wrapped in insulation and will be warm to the touch. This is where freon exits the compressor as a liquid.
Is AC discharge hose on high side?
The High Side AC Hose carries the pressurized refrigerant from the high-side components of the AC system to the low side. The high side (high pressure components) of the AC system includes the AC Compressor, AC Condenser and the AC Receiver Dryer.
Which AC hose is discharge?
The High Side AC hose carries the highly pressurized liquid refrigerant on the discharge side of the compressor to the expansion valve, which is the entry point of the low-pressure side. If the high side AC hose is damaged, it could result in the loss of refrigerant.
Which AC line is suction?
The larger line typically carries a cool gas and is insulated. This is commonly referred to as the suction line, but it is also called the return line or vapor line. The smaller uninsulated line typically carries a warm liquid. It is most often called the liquid line.
