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.
Where is the low side port for AC?
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.

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 happens if you charge AC on high side?
The damage from trying to charge on the high side would be to you – not the system. More than likely the pressure would back up into the can and explode it like a grenade. If you don’t know what you’re doing, seriously get someone to help out. You ALWAYS want to connect to the low side.
Where is the AC drier located?
The receiver drier is a component that protects all the other parts of the A/C loop. It is located between the condenser outlet and the expansion valve inlet, on the high pressure side of the circuit.
How do I recharge my air conditioner?
- Materials Needed:
- Step 1: Turn on your AC. …
- Step 2: Determine if AC compressor is engaging. …
- Step 3: Test the pressure. …
- Step 4: Attach the recharge hose from the kit. …
- Step 5: Restart the vehicle and monitor the gauge. …
- Step 6: Thread the refrigerant can onto the recharge hose.
Which AC line is high pressure?
The pressurized refrigerant is carried from the high side of the AC system to the low side by the High Side AC Hose. The high pressure components of the AC system include the AC Compressor, AC Condenser and the AC Receiver Dryer.
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.
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).
Do you charge AC on low side?
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.
What are the symptoms of an overcharged AC system?
The likely symptoms of an overcharged AC are poor cooling, no air coming out of the wents, weird noises from the engine bay, and check engine light turning on. Because the AC coolant is toxic, fixing an overcharged AC is a job for a professional AC mechanic.
How long does an AC recharge take?
Has your car’s A/C system lost its cool? Refrigerant can leak slowly from your car’s air conditioning system over time, but recharging the system so it once again blows cold air is an easy DIY task and takes just about 15 minutes.

Can Put refrigerant in the high side?
@engineercyprus You can both use it to check the high side pressures, both static and running, and to charge refrigerant, but you’ll be able to charge refrigerant through the high side service port only with the compressor off, after vacuuming the system (if you don’t vacuum, refrigerant won’t get pulled inside).
How can I vacuum my AC without a pump?
- Step 1: Depress the AC system’s access valves. …
- Step 2: Charge the low side valve. …
- Step 3: Disconnect pressure from the high side valve. …
- Step 4: Repeat Steps 2 and 3. …
- Step 5: Charge With Refrigerant.
What should the high and low side pressures be?
These pressures will vary depending on ambient temperature (temperature of the outside atmosphere), but ideally, you will want to see your low side pressure between 30-40 psi and your high side pressure between 150-175 psi.
How do I know if my AC drier is bad?
- Unusual noises.
- Leakage.
- Bad odour.
- Ineffective cooling.
- Cloudy sight glass.
How does a AC drier work?
Receiver/driers contain a material called desiccant. The desiccant is used to absorb moisture (water) that may have gotten inside the A/C system during manufacture, assembly or service. Moisture can get into the A/C components from humidity in the air. This is the “drier” function of the receiver/drier.
What is the AC evaporator?
The evaporator coil is the component in your AC system that absorbs the heat from the air inside your home. It is often either attached to your furnace or located on the inside of your air handler. It works with a condenser coil to complete the heat exchange process that produces cool air.
Can I add Freon to my AC unit myself?
Not only can you not add refrigerant to your air conditioner on your own, but you should never have to! Air conditioners are either factory charged with the right amount of refrigerant before being shipped out to retailers, or they are charged at the time of installation in a dry charge scenario.
Can you recharge your home AC yourself?
Don’t. The U.S. Environmental Protection Agency (EPA) recommends not replacing Freon or refrigerant by yourself for both health and environmental reasons. Only an EPA licensed technician is legally allowed to reclaim Freon.
Do I need to add oil when recharging AC?
Which AC Components Require an Oil Refill? The compressor is the part of the AC unit, It needs enough oil to run smoothly. Typically, there is no need to add oil to the current AC system of your car unless you have modified the compressor or a leak happens, causing the system to drip oil.
Which AC line is cold?
The Copper Pipe (Suction Line) should be sweating and cold to the touch during a hot day. If it is not cold, your compressor could be off (bad capacitor/ hard start kit) or low on Refrigerant.

What are the two main pressures in the AC system?
They are condensing and evaporating – or high- and low-side – pressures. These pressures are divided or separated in the system by the compressor’s discharge valve and the metering device.
Why is my low side AC pressure high?
AC Low Side Pressure Too High Causes
If the air conditioning isn’t blowing cold air and the low side pressure is too high, it could be caused by issues with the condenser fan. However, there’s also the possibility that the system has gotten overcharged with too much refrigerant.
