How Often Does A Car A/c Need To Be Recharged
If your air conditioning is functioning as it should, the refrigerant in your vehicle shouldn’t leak. Though small leaks may occur over time, they are usually not enough to impact A/C performance. For this reason, there is normally not a maintenance or service schedule for recharging your air conditioning system. The best way to tell if it is time for an A/C recharge is to pay attention to your system’s performance. If it feels like your vehicle isn’t blowing as cold as it used to or has stopped blowing cold completely, it might be time to schedule your appointment for an A/C recharge service.
Find Recharging Ports Of The Ac System
Find your A/C systems low-side recharge port next. There will be a dryer/receiver, which is a huge aluminum container, on the large tube between the compressor. In case of difficulties locating it, consult the service handbook. Located on the low-pressure side of the system on the coolant fill port.
It has an L-piece on the top of a little plastic cover. Remove this cap to disclose the port. Make sure the port is clean of any debris. When learning how to put freon in car air conditioner, remember always L-side port is used.

New Freon Regulations in Effect for 2020
For decades, Freon, also known as R-22 and HCFC-22, was the main refrigerant used in residential AC units. However, new AC systems made since 2010 no longer rely on Freon, instead using a refrigerant called R410A, or Puron, that has been shown not to harm the ozone.

Locating The Low Pressure Side Service Port
The first step in the charging process is to locate the low side system service port which is fitted onto the larger of the two refrigerant lines. This line will be one of two which travel out from evaporator core and will lead to the rear of the compressor. You may have to look around a little as these locations will vary and can be obscure on some vehicles.
The low side pressure port will have a smaller fitting than the high side port which will be larger so the kit connector valve will not fit onto it.
In the image below you can see the high side pressure line is always smaller than the low side pressure line. The low side service fitting is equipped with a hard rubber ball valve which the recharge kit connector pushes downward to open and service the system.
Once you have located the low side port twist the cap counterclockwise to remove it. The top of the cap should have an O ring which will seal it to the fitting. If when you remove the cap you hear a leak this valve is bad which can be fixed by simply replacing the cap firmly or replacing the valve once the system is empty, this is not too common.
What Do I Need To Add Freon To My Car
To ensure your personal safety while adding refrigerant to your car, you must have a refrigerant dispenser and protective goggles. It is wise to also wear gloves and an N95 mask to fully protect yourself.
The refrigerant dispenser must have a trigger and a pressure gauge. This will allow you to keep an eye on the pressure levels within the system as you refill the refrigerant levels.

Loss Of Cooling Ability
If you notice your air conditioning system functioning at a lesser quality than you are accustomed to, this could be a sign that the system needs to be recharged.
The air conditioning unit works by circulating pressurized refrigerant, such as freon. When the levels of refrigerant are too reduced, the air conditioning system will not function correctly. This may present as the air not blowing out at all, or the system blowing out warm air.
Find The Refrigerant Fill Port
After you open the cars hood you will have to find the refrigerant fill port that is located on the left side of the engine bay. The fill port looks like a small metal pipe that has rubber hose at either end.
The refrigerant fill port should be near the part of the engine bay that is called a firewall, and you should just follow the larger of two hoses that protrude from the firewall.
Throughout this process, you shouldnt touch parts of the engine bay or the high-pressure hoses since they can be very hot.
The refrigerant fill port has a plastic lid at the top and you must remove it in order to start refilling the cars AC system with the refrigerant.

Detecting Low Freon Levels In Cars Ac
Thecars AC system wont be able to maintain temperatures as low as it normallywould if the levels of freon are low.
There are a number of indicators that the freon levels are lower than they should be, and if you detect any of them it is a sign that you need to add freon to the ACs system. Lets take a look at some of the most common signs of low freon levels.
Diy A/c Charging Does Not Evacuate Old Refrigerant
The reason your car’s A/C system needs to be recharged is that, over time, the refrigerant gas that makes the system work will leak out of the system. This process can take many years — but, eventually, every vehicle will need its A/C system recharged.
When you use a DIY canister to add more refrigerant, you can’t be sure how much is remaining in the system! This can lead to overcharging the system, which can cause significant damage. Instead, our professionals will begin by vacuuming out all the refrigerant from your car’s A/C system. This also removes any moisture that got into the system, which can also cause your A/C to run poorly. Then, once we know your car’s A/C system is totally free of stale refrigerant and moisture, we can fill it up with fresh refrigerant the correct way.

How To Recharge Car Ac After Compressor Replacement
If you find that your vehicles air conditioning is not cooling as it should or you need to know how to recharge the car AC after compressor replacement, youre in the right place. If there is too little coolant in the system, it doesnt perform well. Recharging the air conditioner is cheap and easy to do but it needs to be done properly. Once finished, you will have cool air flowing once again.
An AC system has three parts:
- Evaporator coil
Theyre set up as basically two radiators in a loop with the compressor between them. The system is sealed and filled with fluid called Freon. The compressor takes the fluid and compresses it, creating heat. Heat goes to the outside and the liquid refrigerant goes to the evaporator where it expands and cools. The fan blows the air over the evaporator and into the car, keeping you cool.
Pro TipChrisFix made a detailed Youtube video showing this process. So if you get stuck, be sure to watch it below.
How Does A Cars Ac Systemwork
ACsystems control temperatures through the changes in the pressure. Once you turnon the AC, the compressor is going to compress freon in the system, which willincrease the refrigerants temperature.
Freonwill start losing heat after it reaches the condenser, while the moisture andcontaminants are going to be removed once the refrigerant starts flowingthrough the dryer. The cooling agent is then further slowed down in theexpansion valve where it loses temperature and pressure.
Theevaporator provides additional cooling of the freon and reduces the level ofmoisture in the air, while the ventilation systems blower motor pushes airover the evaporator and into the cars cabin.
Anyincrease or decrease of freon in the cars AC system may cause it to malfunction,and you must perform regular maintenance checks in order to make sure that itis functioning properly.

Recharge Your Ac In 7 Easy Steps:
Because of the sensitivity of this procedure, we will explain how to use the AC recharge kits. They have shown to be the most effective and safest option in comparison to trying to repeat a mechanics role at home.
- Meat thermometer
- Refrigerant .
Safety glasses and gloves
Tip: Always wear safety glasses when performing work under the hood. It is especially important to be careful to not get any refrigerant on your skin as it freezes quickly and is very painful. Please be sure to follow all instructions that are included with your AC recharge kit and read every canisters warnings carefully.
Step 1: Turn on your AC. Start your car and turn your AC to Max or High.
Step 2: Determine if AC compressor is engaging. An AC compressor is a device driven by the accessory belt that converts the refrigerant from liquid to gas. The compressor has a clutch at the end of it that should be spinning with the accessory belt when the AC is on high. Look for these pulleys moving.
Step 3: Test the pressure. To test the pressure, turn the vehicle off and locate the low side pressure port. The low side pressure service port is generally located on the passenger side of the engine bay. It will have a black or grey cap on it with the letter L.
- Tip: If you are having a hard time finding it, try locating the two aluminum pipes that are coming out of the firewall and trace the larger-diameter pipe until you find the service port.
- Proceed until you are as close to 40 psi as possible.

Check The Cabin Temperature
It should now read 18 degrees Celsius. Verify that after reaching its lowest temperature, the clutch disengages and engages again as the vent temperature rises.
These steps should be pretty straightforward to follow. If your cars A/C still doesnt cool the cabin afterwards, then that might be another problem in itselfI suggest you take it to a specialist and have it checked.
How Do I Know If My Car Ac Needs Recharging
In order to know when your car AC needs to be recharge, these are three most significant signs:
Air Conditioner Clutch wont Engage
Usually when the air conditioner reaches its maximum capacity, the clutch engaging starts to click and drivers can hear it very well. The reason for this is that the clutch engages with the AC pressure switchs signal in order to read the level of system pressure. For this purpose, when AC reaches low level, the pressure switch cannot activate, leading to no clutch engaging. This problem stops the system from circulating.
Cooling capability Decreases
One of the most famous symptoms that tells you the automobiles needs recharging is that the overall cooling capability dramatically drops. Why is this a clear signal? Since the system of air conditioning works by circulating a pressurized refrigerant, if the air is not blowing cold air at all, you need to charge your AC fast.
Signs of Refrigerant Leaks
Last but not least, there will be signs of refrigerant leakage. There will be greasy film on many AC fittings or components underneath the automobiles. If there is any, this might be a sign that you need to recharge your AC.

For Items With A Push Button Dispenser:
Shake can well. Start engine and set A/C to maximum cooling.
Locate A/C low-side service port and connect recharge hose.
Depress the top button. Allow contents to flow into the A/C.
While charging, rotate can between 12 oclock and 3 oclock every two to three seconds while continually agitating the can back and forth.
Continue this process until the correct amount of refrigerant is charged into the A/C system or the can is empty.
When the can feels empty, hold it upside down for one minute to dispense remaining contents before removing from service port. DO NOT OVERCHARGE SYSTEM!
Costs Involved In Freon Recharge
Presuming that your car ac is healthy and you just need a top-up, then a can of freon will cost under 50$. But if you have some leakage in the system, then a professional repair can go up to 500$. If you have an older R-12 system, then it will cost around 200$ to convert it.
If any major component has gone bad like a condenser or a compressor, then the cost will increase, and depending on the car make and model, it can cost up to 500$.

Can I Buy R22 Freon Without License
R22 refrigerant is illegal to import and manufacturer in the U.S. But its not illegal for anyone to buy R22 freon. And its not illegal to sell it IF you have a license. As long as the stocks last, you will be able to continue purchasing R22 from specialized dealers and form your air conditioning company.
Disconnecting The Charge Kit
Once the maximum coldness has been achieved and with the engine and system still running release the connector collar to remove the kit. If you shut down the engine and allow the system to neutralize the pressure will rise making it more difficult to disconnect the kit connector.
Pull upward on the valve retainer ring on the valve. Doing this will release the connector and the service port will close automatically.
Once the kit has been removed reinstall the dust cap to the port do not over tighten the plastic cap.
Turn the ignition switch to the off position to shut down the engine the a/c system will shut down as well. Enjoy the cold air!
If an air conditioner repair of any kind is performs it is recommended not to simply add Freon because it will trap moisture and ambient air inside the system which can cause damage. You shouldvacuum down and recharge the system which removes this moisture and helps the system perform optimally.
