What would cause a Air Conditioning unit to freeze?

Answer 1

the outside air unit connection from unit into my house freeze up we can feel a little cold air flow but not enough to cool the house and then the connections freeze up so we shut dirt unit off.

Answer 2

If the unit is used to cool a hot room (above 75 degrees) and the thermostat is set at or below 60 degrees, this would cause the condenser coils to freeze and damage the compressor. That is why it is recommended to cool a hot room gradually rather than expect instant gratification out of your air conditioning unit. Typically when an Air Conditioning unit has been frozen, it requires a service call to repair the compressor due to the damage of the refrigerant not flowing and the compressor overheating.

If the freon is low it could cause the low side tubing of the condensing unit to freeze on the outside of the home. Or if the filter isnt clean it will not allow wenough warm air to go to the return of the heater causing it to freeze up
