There are a few different reasons as to why your air conditioner in Tucson, AZ may ice up, and none of them are desirable. Only a trained professional can determine with certainty what is wrong, so let our technicians have a look and diagnose the problem accurately.
A Dirty Air Filter May Be the Culprit
In terms of an icy air conditioner, this is a best case scenario of a cause. The component that will likely ice up in an AC is the evaporator coil. This is the part in which refrigerant is evaporated, drawing heat out of the air surrounding it in the process in order to cool your home.
If your air filter is very dirty, though, airflow through the system may be restricted. When this happens, the coil may not be able to remove a sufficient amount of heat from the air. It will get too cold as a result, and the condensation on the coil can freeze up. If this is the case in your system, simply changing out the air filter and continuing to do so as needed can be the fix you’re looking for.
You May Have a Refrigerant Leak
Another, more serious issue that can lead to ice on your AC is a refrigerant leak. If you have a refrigerant leak, you may see ice developing on outdoor components and on the refrigerant lines themselves, in addition to on the evaporator coil. Your system does not consume refrigerant, so low levels likely mean a leak is present. Heat absorption is impeded in such cases, hence the icing up of the refrigerant lines/coil.
