5 Causes of Frozen AC Coils

Frozen air conditioning coils can be a nuisance, but they can also lead to serious problems in your AC/Heat system. Below, we’ll go over the five most common causes of frozen AC coils and what you can do to prevent them. 

Cause 1: Clogged Air Filters

One of the common causes of frozen AC coils is clogged air filters. When air filters are clogged with dust, dirt, and debris, it restricts the airflow in the unit, making it difficult for the air to pass through the evaporator coils. As a result, the coils won’t be able to absorb heat properly, which can cause them to freeze up. The best way to prevent frozen AC coils due to clogged air filters is to ensure the filters are replaced regularly.

Cause 2: Low Refrigerant Levels

Frozen air conditioning coils can also result from low refrigerant levels. Refrigerant is responsible for absorbing heat from inside your home and expelling it outside. When the refrigerant levels are low, it impacts the effectiveness of heat transfer, causing the coils to freeze. If you suspect low refrigerant levels, it’s best to call an AC/Heat technician to diagnose the issue as soon as possible.

Cause 3: Refrigerant Leaks

Refrigerant leaks are a serious problem that can lead to frozen AC coils. When refrigerant leaks occur, it affects the heat transfer process, leading to ice buildup. If you suspect a refrigerant leak, it’s best to call an AC/Heat technician right away to prevent further damage.

Cause 4: Dirty Coils

Dirty evaporator coils can also be one of the most common causes of frozen AC coils. If your evaporator coils are dirty, it makes it hard for the coils to absorb heat. When this happens, the coils can become too cold and freeze over. To prevent this issue, schedule regular maintenance services with a professional air conditioning company.

Cause 5: Malfunctioning Blower Fan

The blower fan is responsible for circulating cool air throughout your home. If the fan is not working correctly, it can reduce airflow, causing the evaporator coil to freeze. A certified AC/Heat technician can diagnose and repair issues with this important component.

Preventing Frozen AC Coils

Now that you know the causes of frozen AC coils, it’s important to take preventative measures to avoid the problem. Regular maintenance, which includes replacing air filters, can prevent frozen coils due to clogged air filters. It’s also important to schedule routine services with a professional AC maintenance company to ensure the system keeps running smoothly when you need it most.
