Where is the AC low pressure port located?
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.
Which AC line is the low pressure line?
The low side, or suction line, will be the line connected to the compressor from the top or higher position. It will be cold to the touch and may be wrapped with insulation. This is where freon enters the compressor as a gas.
Where is the AC recharge port located?
The low side port, or the low-pressure service port, is important because it’s the point where you connect to recharge the AC refrigerant. Its location varies by vehicle, but you can find it by starting at the compressor. There should be two tubes coming out of the compressor.
How do I connect my AC Pro to low pressure port?
ALWAYS WEAR GLOVES AND SAFETY GOGGLES.
- OPEN HOOD AND FIND LOW-PRESSURE A/C SERVICE PORT.
- ATTACH QUICK CONNECT FITTING.
- READ PRESSURE COLOR.
- REMOVE PLASTIC SPACER.
- CHARGE SYSTEM.
- STOP CHARGING WHEN NEEDLE IN GREEN.
Do you charge refrigerant on high or low side?
For systems under a vacuum, once the desired vacuum level has been reached, the vacuum pump has been isolated from the system, and no leaks exist, always charge liquid refrigerant in the high side of the system until high- and low-side pressures equalize and liquid stops flowing.
What does S and D mean on AC compressor?
The compressors have two access couplings: the admission or suction connector for the refrigerant gas, which is always identified with letters S or SUC (suction) and the discharge connector, which is always identified with letters D or DIS (discharge).
Is the liquid line the low side?
LIQUID LINE – Pipe or hose connecting condenser to expansion valve. LOW SIDE – That portion of system from orifice in expansion valve through evaporator line or lines through compressor service valve to compressor reed valve. Also called suction side.
Do you fill AC on the high or low side?
The high side fitting is located between the AC compressor and condenser and is the larger of the two fittings. Consult the service manual to verify the exact location of the low-side service port. If hooking a can of refrigerant with a single hose/gauge to the car, you will use the low side.
Do you recharge AC on high or low?
You’ll recharge your AC through the low-pressure port. You should consult your owner’s manual to be sure, but your vehicle will have a cap over the pressure ports. One cap is labeled “H” (for high pressure) and the other is labeled “L” (for low).
What is the high pressure port for AC?
The high-side charge port is a quick-connect fitting that provides access to the high-pressure side of the A/C system. Most A/C systems are evacuated and filled from the high-side charge port in the assembly plant.
When should you not use AC Pro?
When You Shouldn’t Use A/C Pro
- Your car was built before 1994 and has never been converted from R-12 to R-134a.
- You drive a hybrid or electric car.
- It took less than two weeks for your A/C to go from cold to hot.
- Your compressor is running, but the A/C pressure is too high.
- You’ve already added A/C Pro.
Do you charge AC on high or low side?
Every auto air conditioning system has two service ports: one on the high pressure and one on the low pressure side. When recharging with AC Avalanche refrigerant, for safety, you will charge through the low side service port. Never charge through the high side port.
What psi does your Cummins AC compressor cycle off?
Enter your truck HERE to be a part of December’s Cummins of the Month Challenge! My AC compressor is cycling off when it hits 30-33 psi. There is more than enough freon in it.

How to add Freon to a 2015 Ram 2500?
The A/C system in your 2500 consists of a compressor that is belt-driven, an evaporator and freon. If there is a problem with your compressor or evaporator, adding freon will not restore cooling. How to add freon to your 2015 Ram 2500: hook up the can of refrigerant (likely r-134a) to the low pressure port.
Where is the low pressure service port on a Kenmore dryer?
The low pressure service port does not seem to be pictured in the manual. It has to be located somewhere between the fixed orifice tube (which is in the outlet line of the condenser) and the suction of the compressor. This includes the line from the condenser to the evaporator.
