Where is the low pressure AC service port?
The low side service valve is located in the line that runs from the compressor through the evaporator (firewall) and up to the condensor on the low pressure (suction) side of the system.
Are all AC ports the same?
Every A/C System has two service ports: A high side and a low side. The low side line of the system will have a larger diameter metal pipe than the high-side. The low side service port is usually located between the AC compressor and evaporator.

Where is the high side service port AC?
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.
Why is my low side AC pressure low?
Possibility #2 AC low side pressure is too low because the expansion valve or orifice tube is stuck closed or clogged. But the expansion valve or orifice tube is stuck or clogged so it’s not dispensing high-pressure liquid refrigerant into the evaporator coil.
Where is the suction line located?
The suction line is to return gas to the compressor. It is between the evaporator and compressor on a standard cooling system and between the reversing valve and the compressor on a heat pump. On a split system heat pump, the connecting lines are the vapor line and the liquid line.
Where is the AC valve located?
The TXV is located near the indoor evaporator unit of your air conditioner. The main part of the valve is installed on the liquid line, while a capillary tube and bulb sensor are connected to the suction line.
