Air Conditioning Repair

My Air conditioner is not blowing at all and I went outside and there is an ice ball on one of the pipes, what can I do?

Your AC is frozen over on your indoor coil, the first thing to do is go to your thermostat and turn the system switch to off and turn the fan switch to on this will turn the fan on and turn the outdoor unit off this will clear your indoor coil in about two hours.

The coil froze over for a couple of possible reasons you could possibly have had the thermostat turned too low and could have been running the system out of its design parameters this however is the least likely because it would have probably gotten very cold in the house.
You may have low airflow this could be caused by a plugged up filter or a bad blower motor check your filter and make sure your blower is pushing air through the system.
You may be low on refrigerant this would be evidenced by the unit running with good airflow but little or no temperature drop across the unit you will need a set of pressure guages to accurate determine the refrigerant levels
