    #1. Is this a heat pump?
    #2. What coil is frozen, (indoor or outdoor)?
    #3. Are you in Maryland, and what is the outdoor temperature and moisture?

    The beatings will continue until morale has improved. mgt.

    Frozen coils require a tech on-site to evaluate, causes include: 1) Poor air flow - can be as simple as a clogged filter or as extreme as a bad motor 2) Incorrect refrigerant charge... where did it leak? 3) Contaminated refrigerant 4) Restriction in the metering device - moisture 5) Crushed or undersized duct work 6) Mismatched equipment or a combination of multiple items. This condition MUST be remedied - left unattended will wash the bearings out of a compressor.

    May be nothing wrong with it - if it is a heat pump and it is the outdoor coil which froze up ... stand there for a while and it might go into defrost most and defrost itself.

    Inside coil is a different issue, but I doubt the a/c was running in this weather ...

    (Well, okay, I had the a/c on in the vehicle today while out doing inspections, but that's "down here".
