While it’s common to find ice on your air conditioning unit, the problem indicates an underlying issue. In most cases, ice buildup can be addressed through repairs, although replacement may be best depending on the issue. The following guide should help you restore the functionality of your cooling system.

What Problems Cause Ice Buildup on ACs?

Restricted Airflow

ACs take outside air and cool it down with refrigerant. This liquid flows inside the evaporator coil, which uses warm airflow to keep the refrigerant temperature from dropping too low. However, when airflow is restricted, refrigerant can freeze and form ice on the coil.

Dirty air filters or air ducts often strangle airflow. The problem could also be mechanical, such as a malfunctioning blower fan. 

Refrigerant Leaks

As explained above, refrigerant plays an essential role in cooling the air in your home. When levels fall below normal, the pressure also drops. As the pressure decreases, so does the temperature. Refrigerant cycles through a closed loop in your air conditioning unit, so any changes in levels indicate a leak in the system.

Leaks are usually easy to identify since they’re often accompanied by other issues. For example, the unit might blow hot air when powered on. It’s also likely that your utility bills will increase as the device uses more energy to produce the same output. Refrigerant is toxic, so schedule emergency service if you notice these issues and keep pets and children away from the outdoor component.

How Should You Deal With Ice Buildup?

Professionals remove ice buildup and address the malfunctions causing the problem. If you’re facing a leak, they may recommend replacing the system because recharging refrigerant is often costly.

Keep up with regular maintenance to prevent problems in the future. Along with getting annual duct cleaning and changing the air filter every one to three months, have the AC inspected twice per year. During regular inspections, technicians repair broken components before they can cause major issues. For example, a professional will recognize worn tubing and replace it before a full-blown leak occurs.
