It seems like you still have Freon in your can even after filling up your AC. How long does the Freon remain in the can or is it now just wasted since can was open, thus you have to throw it away?
Yes, I still had some left. I used it on another car of my friend. I kept it for few weeks it was still there. I am not sure if it will still be there after a month once the can is opened. I didn't want to overload the Feron.
