If your air conditioner has been developing ice on its exterior, you may be wondering what’s behind the freezing. While the source can be difficult to pinpoint, it’s not impossible. According to the AC repair experts from Biggerstaff Plumbing Heating & Air in Lincoln, NE, there are three main causes of ice forming around your air conditioning unit.

Reasons Why Your AC Is Developing Ice

Lack of Air Flow

Proper air flow is necessary for the air conditioner’s evaporator coil to function. This causes a heat exchange to occur so that the warm air is removed from the house and replaced with cooler air. If something blocks the unit’s air flow, then the heat exchange won’t happen. This could cause ice to form around the air conditioner and will require the services of an AC repair expert to restore its functionality.

Low Levels of Refrigerant

Air conditioners contain a fluid called refrigerant that helps to produce cool air. It should remain at a certain level to ensure the unit operates efficiently. If the refrigerant drops below a certain point, then the system will begin working overtime to expand the fluid that’s left. This will cause the temperature to drop at a rapid rate, resulting in layers of ice along the surface of the unit.

Sudden System Failure

Certain issues can develop within the various components of the air conditioner that will result in a sudden freeze. It might be that one of the refrigerant lines is bent at an odd angle or that the fan within the unit has fallen out of balance. Whatever the case may be, scheduling an appointment with the AC repair experts will ensure that a timely part replacement is performed, preventing the ice formation from getting worse.
