Where is the AC recharge port located?
The AC recharge port, also known as the air conditioning recharge port, is typically located under the hood of a vehicle, near the front of the engine compartment. This port is used to recharge the refrigerant in the vehicle's air conditioning system when it becomes low or needs to be replenished.
Locating the AC Recharge Port
The exact location of the AC recharge port can vary depending on the make, model, and year of the vehicle. However, there are a few common places where it is typically found:
- Near the front of the engine compartment, often on the driver's side
- Behind the headlight or near the radiator
- On the firewall, which is the vertical partition that separates the engine compartment from the passenger cabin
- On the side of the engine block or near the compressor
To locate the AC recharge port, you may need to consult your vehicle's owner's manual or do a visual inspection of the engine compartment. The port is usually marked with a label or symbol, such as "AC" or a refrigerant icon, to help identify it.
Importance of Recharging the AC System
Regularly recharging the AC system is important to maintain the efficiency and performance of the vehicle's air conditioning. Over time, the refrigerant can leak or become depleted, leading to a loss of cooling power. Recharging the system with the appropriate refrigerant and lubricant can help restore the system's functionality and ensure a comfortable driving experience, especially during hot weather.
It's recommended to have the AC system inspected and recharged by a qualified automotive technician to ensure the proper procedures are followed and the correct components are used. Attempting to recharge the system without the proper knowledge and equipment can be dangerous and may cause further damage to the system.
How to locate a low pressure port?
The low pressure service port is located on the larger diameter A/C line that runs from the compressor toward the firewall. To find it, start at the A/C compressor, identify the larger of the two lines connected to it, and follow that line until you find the valve with a plastic cap (usually black or blue).

Step 1: Locate the A/C compressor
- This is a belt-driven component on the engine.
- It will have two metal lines of different sizes coming out of it.
Step 2: Identify the low-pressure line
- The larger diameter line is the low-pressure line. The smaller one is the high-pressure line.
Step 3: Follow the line to the port
- Trace the larger, low-pressure line from the compressor back towards the firewall.
- The port is a valve that sticks out from this line.
Step 4: Check for a plastic cap
- The port is covered by a plastic cap, often black or blue, which needs to be unscrewed to access the port.
- This is the only port that a standard quick-connect charging hose will fit on, ensuring you connect to the correct side.
Which port is the AC recharge?
low-pressure service port
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.
Where is the refrigerant line on AC?
In a traditional split system, the refrigerant lines are located at the back of the outdoor condenser. They connect to the condenser unit, then go through the exterior wall of your home, and eventually connect to the evaporator coil inside the home (in the furnace or air handler).

And right here is the low side service port. Now every car is going to have this lowside service port located somewhere between the firewall. And the compressor.
