    Default AC coils freeze repeatedly

    I have a 2000 square foot house with a 3 year old a/c unit-the main unit is outside and the air handler is in the garage. It leaks constantly,so much that it runs across the garage floor! We suction out the overflow pipe at least once a week. Worse the coils freeze constantly- every 3-4 months. When this happens it continues to run and won't shut off, but doesn't blow cold air. I have it serviced but no one can give me a straight answer as to why it does thisand can't seem to fix it for good.It's broken right now and I live in Florida- any advice? Thanks

    Just some things,usually freeze up has to do with improper charge of refridgerant or air flow or even the blower fan shutting down.
