![]() When the pressure reaches zero, the AC is now fully discharged. If all goes well, the machine will continue to discharge the AC and pull the coolant out. This means that it is doing its job however, if I don't feel any pressure that could easily mean that there is a leak and it will need some fixing. ![]() Normally, when I turn on the machine, there is pressure from the machine. If the refrigerant is pure, removing it is the optimal way to go. If the car does not use pure refrigerant, a filter is added to prevent other substances from entering the machine. This will create a vacuum that will remove the refrigerant from the system. Connect the red line from the machine to the high port and use the blue line to the low port. Most cars have pure refrigerants, but some do not, so it is always better to be safe than sorry.Īfter testing the purity and have determined that it is indeed using pure refrigerant, an air conditioning service machine is connected by using high and low-pressure port caps. This tool is used to connect to the service port and takes a sample of the refrigerant. One way of doing this is through a refrigerant purity tool. The very first thing that you need to do when discharging your AC is to determine first if the system uses pure refrigerant. But will these steps fix an overcharged car AC? We'll find out by learning how to discharge your AC with these steps. Knowing how to discharge AC is something that I highly advise for people who do not want to spend too much on the repair. This is why it is very expensive to restore the AC system and can take a lot of time for us to work on. Once that is done, I will then check the entire system for any damage that may have happened that the overcharged has done. If the source of the issue is the high levels of refrigerant, I often advise the car owner to have the excess amount to be drained to restore it to its normal level or have it replaced entirely. The only way to determine an overcharged AC system aside from the symptoms presented is by having it checked by a professional. I usually end up replacing the entire system if this happens. Extra refrigerant is also mechanically damaging to your car, bringing your insurmountable amounts. The result is a pool of oil, and your system is down for some fixing. Since the compressor is filled with liquid refrigerant, it strains the compressor and compromises the lubrication of the system. This causes the compressor to get overloaded and starts fuming hot air instead.Īnother system that I notice with too much freon is it starts to put too much pressure on the system. The compressor is overburdened by the fact that there is too much refrigerant in the system, so it begins to work harder to move the coolant and cycle it within the system. One sign that I always look out for when it comes to troubles with too much freon is the high temperature when the air conditioning is turned on or if the air conditioner begins to blow hot air. Now, what are the symptoms of an overcharged AC system? However, learning the ways of detecting too much freon in car AC will surely help you in determining whether you should come and visit an auto-technician. I wouldn't want any freon leaks since it can pose a health risk knowing it is made up of different chemicals. This is the main reason why I always tell my regulars to seek professional and reputable technicians when it comes to their car and the AC system. There is a serious consequence of this issue. It is very easy to make such a mistake, and I have done so in the past. I can easily determine that an overcharged AC system is the work of an amateur technician who lacks experience and knowledge with regards to freon and car AC.
