How to Remove Refrigerant from a Car AC Unit
Though, in your car’s air conditioning system, refrigerant is a designed mixture/working fluid that converts hot air to cold air. As a result, it assures heat absorption and release, resulting in cool air for your comfort via your car’s AC. So, a low refrigerant level might interfere with the correct operation of the AC system, resulting in various symptoms.
Follow these step-by-step instructions to drain R134A from the car or any other refrigerant from your vehicle if you begin to notice indicators of your car AC malfunctioning, such as when your AC is not blowing cold air, when your AC is spewing hot air, and so on.
Step 1: turn off the inside thermostat.
Step 2: Determine the low-pressure side of your car’s refrigerant and the suction size of the compressor. The suction valve for the compressor installs in the condensing unit. Connect the low-pressure side of the refrigerant to the suction side of the compressor.
Step 3: Using a wrench, close the service valve on the low-pressure side of the condensing unit. Depending on the kind of valve, you may need to use a hex key rather than a wrench to block the service valve.
Step 4: Slightly shut the high-pressure service valve. Make sure not to totally close the door. Allow the hex key to remaining in place.
Step 5: Using a low-voltage jumper, engage the compressor.
Step 6: Let the low-pressure valve drain.
Step 7: As soon as it reaches the vacuum, close the service valve.
Finally, turn off the compressor. Step 7 and the last step of de-energizing the compressor must be completed quickly since failure to do so may result in compressor damage. A faulty AC compressor would aggravate the difficulties with your vehicle’s air conditioning system. It is critical to have someone around to assist you with this removal procedure.
