Why Does My Air Conditioner Keep Freezing Up
Camila Farah
Your air conditioner keeps your home cool by removing heat from it.
This can cause your evaporator coils to freeze. If there is insufficient airflow then this heat exchange cannot properly take place. At some point an ac unit may freeze up when the balance between maintaining coolness at home and making sure that the machine is functioning is not kept. You have air flow problems.
What causes an ac to freeze up. Low refrigerant levels make the coils too cold and a faulty fan prevents air from moving. A freeze up can also be caused by low refrigerant and improper fan operation. The following are some of the key reasons why your ac may be freezing up.
Blocked air flow causes freezing up air conditioners need to have a constant flow of air so that humidity can t settle on the coils and freeze. Dirty coils can cause freezing because the layer of dirt on top of the coils can prevent them from absorbing the water fast enough. Before you do so though you need to turn off the ac so that the frost or ice that has formed upon it can melt. Simply put your air conditioner is freezing up because something is either causing the freon in your system to expand more than it is designed to which in turn is making your coils colder than normal or something is preventing the air in your house from transferring its heat into your system.
