If your air conditioner freezes up, there are a few common reasons. One reason is that the airflow is restricted in some way. When the air flow is restricted, there is no air moving through the system to keep the condensate coil from freezing. Many times it is a simple inexpensive fix such as a dirty air filter. If your air conditioner freezes, you should turn it off and allow it to defrost by a letting the fan run for a couple hours, allowing the coil to thaw. Keep in mind that the technician cannot work on a frozen system. Another cause of a frozen air conditioning system is a refrigerant leak. When you have a leak, it is possible to get refrigerant added to bring it back to the level recommended by the manufacturer. You can have a leak sealant added but it is a temporary repair and there is no telling how long it will last. You may want to consider investing in a new system depending on the age of it.
