    Carrier A/C unit just blew out all refrigerant in 5 minutes!

    It sounded as if you unscrewed the valve stem out of a tire full of air. It was that loud, I knew it was the freon/refrigerant coming out so I was already mad. I tried to take it apart to feel for the leak but I wasnt fast enough, it was all leaked out by the time I got in there. It sounded like it came from the condensor coil area, most of that is hidden. This must be a big leak though.

    It had been working fine and I know it was just turned on for the first time that day, my wife just turned it on. I depressed both shrader valves in and theres no pressure left, nothing.

    The unit is an energy efficient Carrier. Doesnt look too old. Model number is
    38BYCO36348. Any common places I can check? It seems like something came completely apart or unscrewed. Im gonna take a big hit if I have to spend 2 or $3,000 dollars for a new unit.

    Ive fixed this unit atleast once every year from the start capacitor to the contactors but this is a bigger job so I need to ask advice first. Thanks guys!

    your going to need to call a pro, cause if it's got a leak, then he not only has to weld the leak (if possible), but pull a vacuum, and recharge it. None of these things you'll be able to do without the proper equipment and licensing.

    I was gonna see if I could find the leak first. By the sound of it the leak is big so it shouldnt be hard to find but it doesnt look those parts are seperately replaceable. It looks like they are all one piece so I dont know. Even if I find the leak I might not be able to replace just that piece.

    some pieces are replaceable, some are repairable. Just depends on where the leak is.

    The longer you wait, the more contaminants from the air that can enter your system and potentially cause further problems.

    Have a peek AFTER you make the phone call.

    Whats the average cost to refill so I dont get ripped off? It takes 8.00 lbs of R-22. Im in south Georgia. Thanks!

    Also, wheres the date on this thing? The lables look very new. Is it possible its still under warranty? We've lived here 2 years now.

    it may say it's factory charged with 8# but that may not be what it takes. Depends on lineset length, size, if it's matched with the proper coil. And as for pricing it depends on location as that changes quite regularly. As for it still being under warranty, if you are not the original purchaser or did not transfer any warranty from the previous owner then it most likely will not be covered.

    as for the date code it's in the serial number.

    The refrigerant circuit is under a lot of pressure. Big or small, the leak will sound big. You gotta be licensed to handle or buy refrigerant. Call a local pro.

    Probably blew a terminal.

    Even if its not the compressor terminal and its a simple leak repair, wait until you hear the new price for R22!
