Where is the AC recharge port located?
Both ports are located on the air conditioner’s metal pipes. The low-side port, like the name suggests, is lower on the pipes towards the front of the engine. While the low-side port is intended for recharging Freon, the high-side port is used for maintaining an air conditioner’s internal pressure.
Which port do I use to recharge my AC?
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.
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.

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.
Does the car need to be running to recharge AC?
It does not engage when the refrigerant pressure in the AC pipes is below the safe level. This is because running the AC with low refrigerant pressure can destroy the compressor. To check for this, open the hood of your car, start the car, and ask someone to turn the AC on. In that case, you need to charge your AC.
How do I add freon to my car?
To fill the system with refrigerant:
- Squeeze the trigger for 5-10 seconds, slowly tipping and shaking the can.
- Wait 30 seconds for the pressure to equalize.
- Read the pressure displayed on the gauge again.
- When the pressure is correct, stop filing the system and wait a few minutes.
Can you charge AC on high 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.
Can you put freon in the high side?
The freon is added on the LOW PRESSURE SIDE ONLY. The hose tool you bought is made so you can only hook to the low side as the high side and low side fittings are different sizes and shapes for SAFETY’S SAKE.
