  • R134A in a can

    Posted by Bill on July 18, 2026 at 10:30 am

    Can I use the canned R134A freon at the auto store to put a bit more gas in my drivers A/C system? No commercial gauges, just wanting to pump some gas in there and see it I can top it off.

    Every summer ( over the last 10 years) I end up adding 1/2 to 1 can and at $10 a can at Walmart, it has been easier to do this than find where the loss is coming from

    So do I just hook up the can and then open the suction valve with the engine running and pull the trigger?

    Yes, I just add in a little at a time and watch the indicator as well as wait a few min and see the temp at the dash. I set the temp down to 55 and fan on high.
