A Mechanic’s Tips about an AC recharge
- Always leak test the AC system before a refill.
- Always vacuum test the AC system before you refill the AC. Condense, or water in the AC system may damage it quickly.
- Check the AC compressor clutch and the AC pressure sensors before you do any advanced work on your AC system. If the AC compressor clutch is not engaging, you might be able to remove some shims inside of it to make it functional for some more time.
- The best way to find AC problems is to connect the AC machine – Empty the system, put vacuum for 20 minutes. Check for any leaks and then refill the system with leak detector fluid, oil, and refrigerant. Let it run for 20 minutes and check the function and look out for any leaks. If everything seems fine, you can give the car to the customer. If it is not fine, empty the system again and repair any leaks and continue the troubleshooting.
- Pressure tests are a better way to test for leaks than vacuum tests. Vacuum tests can seal the small leaks.
What is a AC recharge?
All cars AC systems leak a little bit every year. After a while, you need to recharge the AC system. Before you do an AC recharge, you test for any leaks and test the system’s function.
How serious is low AC pressure?
The only thing you may notice when the AC pressure is low is that the AC is not working. However, some newer cars have a variable AC compressor, which can get seriously damaged if the AC system is empty. If you have an ac compressor with a clutch, you do not have to worry, though.
How often do you need to recharge the AC?
There is no specific schedule for when you should recharge your AC. Usually cars AC system have to be recharged every 6-8 years for natural reasons if you need a recharge before, there is probably a problem with a leak somewhere.
What are the symptoms of low AC pressure?
The only symptom you may notice is that you will not get any cooling effect inside your car. You might also hear the ac compressor go on and off on idle if you have an ac compressor with a clutch, though.
