Your home's air conditioner is probably the appliance you rely on most during the warm summer months. Without a functional air conditioner, it would be extremely difficult to maintain a cool temperature inside your home. One reason your AC system may fail is the formation of ice on the coils. Coils can freeze up for a number of reasons, but the most common is a lack of proper airflow moving through your AC unit.

Learn more about airflow problems so that you can better maintain your AC unit over time.

1. Damaged Ducts

A network of air ducts helps move air throughout your home. These ducts must function properly to maintain the balance between cool and warm air moving through your AC unit. Should one of your air ducts become so damaged it collapses, airflow can become restricted. For example, too much cold air will build up inside of your AC condenser. This buildup of cool air causes the coils to freeze over, which compromises the function and stability of your air conditioner.

Have an HVAC professional check your ducts for damage on a regular basis to avoid frozen AC coils.

2. Faulty Blower Motor

Once air has been cooled inside your AC condenser, a blower fan pushes it into your home's duct system to be distributed throughout each room. The blower motor can sustain damage if it is not properly maintained over time. Unfortunately, a faulty blower motor prevents cool air from being pushed out of the AC compressor. Once the fan blades stop turning, air doesn't flow over your AC system's coils properly. The result is the formation of ice on the coils.

Having your AC system checked regularly by an HVAC professional will help you catch blower motor problems before they can interfere with airflow in your AC unit.

3. Clogged Air Filter

All of the air that is cooled in your AC unit is drawn in from the outside environment. This air passes through a filter that eliminates any contaminant particles. Eventually, the air filter can become too clogged to allow for the easy transfer of air. As such, experts suggest that you change out your AC air filter at least once every 45 days to maximize the efficiency of your cooling system.

If you allow your AC unit to run with a clogged filter, the lack of airflow could cause the coils in your unit to freeze up. For more information, contact a company that provides air conditioning services.
