How To Recharge Your Car Air Conditioning
When your cars air conditioning begins to lose power and doesnt blow cool air, it may be time for an AC recharge. Recharging your AC means adding more refrigerant to your AC system to allow the air to start blowing cold again.
Important to know: recharging your AC is a temporary fix to a likely bigger problem. If your system is indeed missing refrigerant, your air conditioning system has a leak and needs to be inspected and repaired with a certified mechanic. Refrigerant does not evaporate in an airtight system, so air must be leaking in.
- Note: Some older vehicles cannot have their AC unit recharged. These vehicles generally fall before the year 1995 and use an R12 refrigerant no longer made. The only option is AC replacement.
Though an ac recharge can be completed at home, it is still considered a more professional repair, as it contains work with hazardous liquid and is best left for a certified mechanic.
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.
Connecting The Recharge Kit
In the next step, remove all the safety located at the valve base determined by the white or red plastic tags. After that, pill the retainer ring upwards onto the low-side service port for attaching the connector.
While performing the procedure, you will hear a slight amount of pressure being released for a minute second.

Reading The System Pressure
After attaching the charge kit the gauge will indicate the static pressure in the system . If the system is flat with no pressure showing on the gauge there is a leak that must be found and corrected before charging can begin which we cover further on in this article. The system in the example is simply low on charge which is indicated by the gauge. The needle should be in the green for a sufficient charge.
Connect The Dispenser To The Fill Port
You must stick to the instructions closely while attaching the dispenser to the fill port, and try to complete the entire process as quickly as possible. The first thing you will need to do is get a firm hold of the dispensers connector and then lift its outer sleeve.
Squeeze the trigger to remove all traces of air from the hose that connects the dispenser to the fill port and then push the connector to the fill port while still squeezing the trigger and holding the connectors sleeve.
Pressing the trigger ensures that an even flow of the refrigerant is coming out of the connector which reduced the chances of air or moisture reaching your cars AC system.
As soon as you release the sleeve the connector should fall in place, and then proceed to release the trigger. Double-check if the connector is correctly positioned on the fill port before you start recharging the AC system.

The compressor gets pressurized by the A/C clutch in your car. When you switch on the a/c in your car, you will hear a clicking sound. When the AC clutch engages, that sound is what is heard.
The A/C clutch detects the level of Freon. It shows that the Freon level is way too low when it fails to engage. Additionally, it is a sign that there is insufficient refrigerant in the car for the compressor to compress.

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.
If the clutch on the compressor is indeed engaging, then it is likely that the system is low on refrigerant, especially if the air is still blowing slightly cold. You will still want to move ahead with testing the pressure before adding refrigerant.
If the clutch is not engaging the compressor, then the AC system is either very low on refrigerant, there is an electrical problem, or the compressor itself has failed. Adding more refrigerant after pressure testing will allow you to know which of these the cause is.

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.
