Car Ac not blowing cold,worked for few hours after Refrigerant charging?

If you need dis-assembly or replacement instructions for any other auto/car part, or you want to ask question related to your car/truck jeep problem then please leave the comment with your details, so I can provide you the required instructions and solutions.


Its a leak,confirm leak problem.


If you charge the system and works for a time ,(hour, week, year) and then quits it sounds like perhaps the Freon is leaking out somewhere. Freon does not ever get converted to air. Freon is in several states of existence while it is in your system. It is a high pressure liquid, high presure gas, low presure liquid, and a low presure gas, but it is still always Freon.
There is a valve called an expansion valve. What it does is to take the high presure "liquid" freon and allows it to pass into a low presure zone called an evaporator at a regulated rate. When you take freon at a liquid state high presure condition and expose it to a low presure environment it "evaporates" ( thus the name evaporator) and it gets very cold when it does this. This is where the cold air you feel coming out of the vents is made.
But the freon is in an enclosed system. By this, I mean it is never exposed to air, moisure (water), or anything else. It goes through all of these changes while inside this enclosed system.
Therefore, if the enclosed system is good then the amount of freon inside it will not change. If the amount of freon doesn't change then adding more will only make things worse.
I would suggest having the system checked with a hologen leak detector and/or system dye to find the leaks. Remember, if you have to add freon, then the freon that was there before must have escaped from somewhere.
Find a reputable shop to check the system for leaks. If it is leaking bad enough to run low in a hour it should be an easy to find leak.
This basic troubleshooting will help.Thanks.
