You can charge the system on your own with a billing kit and also some refrigerant, as long as your automobile utilizes r134a refrigerant.  First, you’ll need to check for leakages. After that, inspect the refrigerant stress as well as check your system. Ultimately, you can include your refrigerant and finish the recharge. If you have a crossbreed or electric car, don’t try to recharge the ac unit yourself, as it can cause a dangerous electric cost.
- Spray soapy water onto the air conditioner elements to find leakages. You can use meal soap and also tap water. Ensure the whole system is coated to make sure that you won’t miss out on a leak. If there are leakages, you’ll see bubbles developing around the leakage.

Adhere to all instructions on the tag, including extra advised protective gear.
- Locate the low stress line port, which will certainly have thicker tubing. There are two ports on your ac system. You will include the refrigerant to the low stress line port, not the high pressure line port. The reduced pressure line has larger tubes than the high pressure line, making it simple to compare the 2.
Often they are identified with “H” for high as well as “L” for low. In some lorries, the reduced pressure line port will certainly be lower than the high port, but this is not constantly the case.
Many kits have a connection that just fits onto the low pressure port, making it less complicated to pick the ideal port.
- Eliminate the port cap by loosening it. The cap is the little plastic cover that secures the valve. Once it’s off, make sure you put it someplace risk-free to ensure that you don’t lose it.
- Hook the stress scale pipe to the port. Merely click the scale port over the open port. You can wiggle it gently to make sure it’s connected.
If it’s loose or comes off, try to connect it once more.
It’s ideal to pick a recharge set that includes a pressure gauge. This enables you to conveniently add more refrigerant without overcharging your ac system.
- Inspect the analysis on the pressure gauge. The gauge will certainly offer a reading in psi. It needs to have colored areas to suggest if it remains in a risk-free array. Environment-friendly indicates excellent, but your levels could still be lower than needed to cool your car if it’s low in the environment-friendly area.
Your ideal pressure will be established once you check the outside temperature. You’ll do this when you test your system later in the recharge process.
- Wage the recharge if the stress gauge reading is over 0. An analysis of 0 methods that there is no refrigerant left in your air conditioner, which will certainly call for a repair by an expert service technician. Or else, you can bill the system yourself using your charging set.
Testing Your System.
- Crank your engine as well as turn the A/C on high cool, high fan. This permits you to examine to ensure your components are working. It’s alright if your a/c unit is blowing warm or hot air currently.
Your hood should still be up.
- Make certain the compressor clutch is spinning. The compressor clutch looks like a circle. It might spin quick or slow-moving, depending upon how well your system is working, along with how much refrigerant exists in the system.
If it’s not rotating, then you can include half a container of refrigerant as well as check it once more. If it’s still not spinning, after that you’ll require to take your cars and truck in to a professional technician.
- Set the refrigerant temperature level scale to the ambient temperature level. The scale will inform you what your refrigerant pressure must want you finish your recharge. This is your recommended pressure degree. As you charge the ac unit, you can check the pressure on your pressure scale.
It’s all right to round up or to the local 5 degrees.
- Inspect the pressure scale to make certain it remains in the white or green zones. The existing stress degree ought to be below the recommended level you just established, based on the temperature level scale reading that you took. If it’s above the recommended level or in the red area, you require to take your car to a professional because something else is wrong.  Do not add more refrigerant if the degrees aren’t reduced. This could harm your auto.
- Switch off the vehicle before including refrigerant. After you finish examining your system, it’s ideal to turn off your system, unless the instructions on your billing package say or else.
Always adhere to the directions on your charging set to ensure that you obtain the very best possible results.
- Loosen the trigger from the can to remove the internal cap. The inner cap is what keeps the refrigerant trigger from puncturing the can prior to you prepare to utilize it. You need to see where the can screws into the trigger, as it will have a typical joint.
Dispose of the inner cap.
- Screw the top back on, which will certainly pierce the top of the container. There will certainly be a steel pin inside the trigger. As you screw the can back on, press hard to make sure that the metal pin pierces the top of the can. You ought to listen to the pressure release inside the canister. It will certainly now await use.
If the trigger pin doesn’t puncture the can, after that you won’t have the ability to make use of the product. In the unusual occasion this happens, you can try removing the trigger as well as weighing down harder as you change it once more.
- Shake the can to blend the contents. Intensely tremble it backwards and forwards. This will make certain that all of the additives are mixed to make sure that you obtain an even application as you reenergize the ac unit.
If the active ingredients aren’t mixed well, you can experience some clogging as you use the item.
- Link the refrigerant to the reduced stress line port. You might need to pull back on the edge of the port to make it fit around the port. Push down till the kit affixes to the port. You can shake it gently to see to it it’s completely attached.
If it feels loosened or comes off, try once again.
- Press the trigger on your refrigerant. This will release the refrigerant right into your ac system. Maintain a firm hold as you hold the container.

- Check the stress after 10 seconds of charging. Let go of the trigger as well as check out the stress gauge. It is necessary that you not put way too much refrigerant right into your ac system.
If your can has a handle as opposed to a trigger, after that you should transform the knob to shut the shutoff after 10 secs.
You’ll possibly need to include refrigerant a couple of times to reach the desired stress. Take your time, however, so you don’t overcharge the system. Overcharging makes your system run ineffectively as well as can harm it.
- Repeat until your stress gauge gets to the proper reading. Press the trigger for 10 seconds at once. Gently move the can backward and forward as you bill the ac system. Keep in mind to check the stress frequently.
Finishing the Recharge.
- Detach the refrigerant connector from the port. You may require to bring up on the collar around the connector to break the seal. Then, remove the port and place your charging package in a risk-free area.

This is the cap you got rid of at the beginning and also put in a refuge.
- Check your a/c unit to see to it the air is cold. It must really feel cold on your skin. You can inspect the exact temperature utilizing your temperature level scale. It needs to be blowing in between 38 to 45 ° F (3 to 7 ° C).
