    Default Odd A/C performance..

    My AC started doing this near the tail end of summer last year, so it wasn't too big a deal, but here we are coming back into summer soon, and I'd like to figure this out sooner than later.

    About half the time, the AC works perfectly, as it is supposed to. No troubles.

    The other half, it will run cold like it is supposed to, and then randomly, it will start warming up. Sometimes, it will do this after the AC has been on for 5 minutes, sometimes, after it has been on for 20. What I've been doing is turning off the AC, then turning it right back on. Sometimes this works, sometimes not.

    I thought maybe the system was low on freon, but considering that when it is running, I can get 50 degree air out of the vents, I'm not so sure that it's low.

    Any suggestions on what might be causing this?

    I'd check the system, it's probly low on refrigerant and freezing up depending on the humidity!!

    Check the freon level , 50 degrees isn't very good at the vent.
