The only real accurate method for recharging a system is to remove all of the refrigerant from it, vacuum the system, and then recharge while weighing the refrigerant until the amount charged equals the system label. Since most homeowners do not have shade trees, if the temperature outside is above about 75 degrees Fahrenheit, attach R134 to the low side port, insert a cheap autoparts vent thermometer into the main a/c vent, set the system to the lowest setting, recirculate, and turn on the full fan. Once the thermometer registers a reading between 36 and 42 degrees Fahrenheit, start charging the refrigerant. At that point, halt and unplug the hose from the cap port.
For the OP, if your system was nearly out of refrigerant, you have a significant leak, and the fresh charge won’t last for very long. Additionally, you might be losing compressor oil near the site of the leak, which could result in a broken or seized compressor and cost a lot of money to repair. Check all hose couplings and metal pipe joints thoroughly for greasy buildup.

Quick disconnect fitting for AC recharge charging port
Some recharge kits have this fitting that quickly and securely connects to the AC recharge charging connector.
Your air conditioner probably lost some refrigerant during the winter if it was blowing ice-cold air last year but is now hardly cooling. When aging seals shrink and some refrigerant leaks out, that occurs in older automobiles.
Typically, turning on the automobile air conditioning will send you back to the freezing cold. If your car was built after 1993 and is filled with R-134a refrigerant, you can complete that task by yourself (to make sure, check the label under the hood or the specifications section of your owner’s manual).
Restrictions may apply to the sale of R-134a refrigerant to consumers in several states. The cans may occasionally be designed differently, necessitating various charging techniques. All AC issues won’t be resolved by charging the AC. However, if you’re willing to risk $50 on a rechargeable ac kit, you could become a cool dude in less than an hour. By performing the auto ac recharge yourself, you can save roughly $100 on labor.
Pick up an R-134a A/C recharging kit at any auto parts store. Because it included a quick-connect fitting and reusable gauge, as well as a seal conditioner ingredient in the refrigerant, I used the A/C Pro product you see here. For an AC recharge for a car, however, any brand will work. A word of caution: Many commercial recharging kits utilize oils and seal conditioners that are incompatible with the electric AC recharge compressors in hybrid vehicles. A fatal electrical shock might be caused by using the incorrect auto ac recharge kit. Before making a purchase, verify that your hybrid vehicle is compatible with the car ac recharge product on the label. Consult a professional if you’re unsure.
Caution
If used incorrectly, refrigerant can result in frostbite and severe eye damage. Wear gloves and goggles when doing the process, and pay close attention to all the warnings in the package instructions.
When ought the AC in a car be recharged?
Most of us are spoilt by modern life. We are accustomed to driving with adjustable seats, automatic transmission, and GPS to ensure we never get lost. For ultimate comfort, we also anticipate a cooling system that we can regulate to the ideal temperature.
You likely take the air conditioning on your automobile for granted. That is, until it perishes in the sweltering summer heat of North Carolina. Then you understand how much you value it.
The air conditioning in your car might be disregarded until it breaks down. I hope this doesn’t happen on a long drive away from your go-to neighborhood mechanic.
Alternately, you might plan routine AC recharge services. Most likely once every year or two will be plenty. The time to accomplish this is in the spring.
How can I refuel my r134a car air conditioner?
To replenish or top off the refrigerant in your car’s air conditioning system, turn on the engine, set the air conditioner to the coldest setting, and open the doors to prevent the air conditioner from shutting off when it gets cool inside the car. Let the engine and AC system run for about five minutes before adding refrigerant.
In my car, where do I place the Freon?
Remove the hood.
2. Find the refrigerant fill port on the system’s low pressure side. A little plastic lid with a L printed on the top will be attached to this. To access the port, unscrew this lid.
The low pressure side fill port is often found on the left side of the engine bay on most cars. It frequently takes the form of a short metal pipe with two lengths of rubber hose emerging from either end. Look at the “firewall” at the back of the engine compartment. There should be two pipes or hoses sticking out from the firewall, one bigger than the other. The low pressure side fill port can be located by following the longer hose. The photographs show where the fill port is on two various late-model engines.
DANGER! Never handle anything you’ve never handled before. Nearly everything in the engine bay is in motion or becomes warm. Do not touch the high pressure side’s tiny pipes; they become quite hot. The low pressure side hoses can be touched, and they should be at room temperature.
How much R134A is required for my car?
The average automobile can contain between 28 and 32 ounces of refrigerant, or roughly 23 12 ounce cans, although larger vehicles and those with rear air conditioning will probably be able to hold more. The system capacity for your particular vehicle can be found in your car manual.
Do AutoZone air conditioners require recharging?
Most of the time, this may be resolved by using a trusted stop leak additive to halt any leaks. Visit AutoZone for an AC recharge when the time comes. Along with other things, we sell R134a refrigerant, PAG46 oil, AC stop leak, and AC system cleanser.
Will AutoZone re-charge your automobile using Freon?
If the system has been overcharged, it is best to have the car serviced so that the system may be properly evacuated by an AC machine and then serviced to the proper level. Alternatively, AutoZone has all the equipment and refrigerant necessary to service your R-134A or R-12 car if you choose to handle the work on your own.
How much does it cost to recharge the AC in your car?
Taxes, fees, and your specific make and model are not taken into account in this price range, which is based on national averages for all automobiles. It may also be necessary to do related maintenance or repairs including replacing the fuel filter, the O2 sensor, and the spark plug wires. Use the RepairPal Fair Price Estimator to get a more exact quote depending on your make, model, and location.
Why isn’t the AC blowing chilly air in my car?
The requirement for a recharge is the most frequent reason why a car’s air conditioner doesn’t get chilly enough. You can replenish your refrigerant on your own, but scheduling an appointment with a neighborhood reputable auto shop will save you time and ensure the service is done correctly.
