If you notice condensation around your air conditioning unit, lukewarm airflow, and elevated utility bills, check the exterior component of your AC. In some cases, the unit may be frozen, a problem primarily caused by two issues. The guide below should help you deal with this issue to improve the device’s functionality.

Ice Buildup From Airflow Problems

Evaporator coils transport refrigerant, which can freeze if there isn’t enough warm air circulating through the machine. Warm air intake can be compromised if the coils or filters are dirty. Closed vents and collapsed ductwork also prevent indoor air from coming into the unit, freezing the evaporator coils. 

First, check if all vents are open. If so, change the air filters. If the issue persists, call an HVAC contractor to clean the evaporator coils. They may also identify and repair damage in the blower or ducts to restore the functionality of the air conditioning unit.

Ice Buildup From Lack of Refrigerant

Also known as antifreeze, refrigerant absorbs indoor heat and moves it outdoors. If it leaks due to holes in the refrigerant lines, levels drop and compromise the functionality of the evaporator coils as explained above, lowering their temperature and causing them to freeze. In this situation, the air blowing from your AC may be warm.

Refrigerant is a toxic substance, so this issue requires prompt attention from a professional. Turn off the equipment and call an HVAC contractor to repair the lines and recharge the unit. Since recharging is often costly, it may be more cost-effective to replace the AC if it’s over 10 years old.
