    My ac is blowing warm air
    My ac r22 3ton unit is blowing worm air after working for an hour or two normally. I would then have to turn it off for about 4-5 hours to get cold air again. I do know the lines are not freezing neither the coil. What can it be? Please help

    If the outside unit is not running, it is probably (not certainly, but probably) the contactor or the breaker to the codenser.

    If the outside is running, it may be low on freon.

    The first issue is an easy replacement (But BE SURE that the breaker is OFF to the condenser), but the 2nd issue requires a licensed repair person.
