Air conditioners can freeze, and if you have found that your air conditioning system has been freezing, this is the problem and how you (or we) can fix it.
Why do air conditioners freeze up?
The cold coil in an air conditioner can become TOO cold. The warm air that flows through the system from the building brings the temperature of the cold coil to a reasonable temperature that allows the air conditioner to run correctly. When the airflow from the building can't get to the coil, it freezes. The condensed water doesn't get the opportunity to drain away from the unit without that warm air.
Other issues that can cause freeze ups are low refrigerant and fan operation issues.
How do I prevent an air conditioner from freezing up?
To prevent an impedement of air flow, make sure that filters are replaced each month and that registers are clear and open.
If the air flow is working well, replenish the refrigerant. Without adequate refrigerant, the coild get too cold.
Last, if the air flow and refrigerant have checked out to be okay, look into the fan. If the fan is faulty, it will prevent the air from moving and freeze the coils.
