don't do it unless you are planning on selling/scrapping the car or are never planning on having the ac work properly.
this makes no sense whatsoever.
its simply refrigerant. refill it shouldent be a problem.. the gas is the same gas that the factory put in it. Theres only a few components that could screw up in an a/c system if its not leaking, the most likely is the compressor, if your system is full and the compressor isnt working then thats the first step.. Normally you will be able to visually see if its working or not.
whether you have a leak or not, thats different.
hell even if its a slow leak the new gases dont deplete the ozone (or just try a stop leak) for 16$ a can even if it lasts through the hottest months you win.

The gas is the same that the factory put in it? Not too sure about that. You might want to research what you are talking about before giving "advice" which is false.
depends on car but before r-134a there was r-12 and it seems that you can run r-134a in an older r-12 system.
if you change the composition of the gas it cannot be called r-134a theres only 1.
what would be the "right answer" if im wrong?
the gasses used in cars are pretty standard and must conform to strict regulations.. you can find the gas your car uses under your hood.
The right answer is to go to a certified garage to get your a/c system checked, purged, and refilled. There is a reason why mechanics working with r134a must be certified by LAW and the people buying the r134a must be certified by LAW.
You can no longer buy/use r12. It is not the same as r134a
The bs they sell over the counter at auto parts isnt "the same as what automakers put in their vehicles."
If you fill your system with something other than r134a, which is what is offered at canadian tire, walmart, etc.. etc.., then you will contaminate your system. It may work for a while, but if your a/c is empty it is obviously because there is a leak. You fill it with duracool and it will leak. So say one day you get fed up of spending the 50$ or whatever for duracool everytime and decide to get the system fixed. You will need to fix the leak, replace your dryer (which is suggested regardless), have your a/c system flushed, have to find a garage willing to recuperate your contaminated gas, and still need a purge/test/refill. So why not just save your time and headaches and get it fixed properly and legally from the start?
That's all im saying... If I were to sell my car tomorrow and the a/c was empty, id fill it with propane. If I were keeping the car, I'd find the leak and fill it with r134a.
