Ice on your AC’s coolant lines can be a sign of two distinct problems: limited airflow and low refrigerant. Both of these issues require air conditioning repairs. To help you understand this issue in-depth, learn about how poor airflow and low coolant can cause frozen condensation.

Why Is Ice Forming on My AC Unit?

Limited Airflow

The outdoor component of your AC is known as the condenser. Coolant that can reach temperatures of 10-20 degrees Fahrenheit passes through the condenser’s evaporator coils, the component in charge of cooling the air in your home. The condenser requires heat exchange to occur with the surrounding air, and if there’s not enough airflow to the condenser, moisture in the air may freeze on the evaporator coils.

This problem can be caused by bent or blocked condenser fins, too much foliage growing near the condenser, or a dirty condenser. To fix this issue, you can have an air conditioning repair expert tune up and clean your condenser for optimal performance.

Low Refrigerant

Your AC’s indoor unit uses coolant to absorb heat before circulating it outdoors to be dissipated in the condenser. However, if there isn’t enough coolant circulating, it may struggle to absorb enough heat indoors, which results in colder coolant reaching the condenser. This can cause ice to form on the lines.

Because coolant circulates in a closed system, low levels indicate a leak, which should be addressed immediately by an air conditioning professional. Coolant is a toxic chemical, so never try to handle this problem yourself.
