Ice forming on or in your Lake Forest, IL air conditioner typically indicates system trouble. However, various problems may be the culprit. Let’s take a look at several possible causes of ice forming on your AC system.
Clogged Air Filters
Dust or other debris clogging your air filters is a common cause of ice forming on your AC. Clogged air filters restrict airflow through your air conditioning system.
Restricted airflow leads to excessively cold evaporator coils, freezing condensation into ice. To help prevent this, be sure to replace your air filters every two to three months.
Low Refrigerant Levels
A refrigerant leak is a common cause of low refrigerant levels, which affects your system’s ability to transfer heat out of your home. If this occurs, you’ll hear hissing or gurgling sounds from your system’s lines. To address low refrigerant levels, a technician must fix the leak before replenishing the lost refrigerant.
Ductwork Obstruction or Leak
Ductwork obstructions or leaks may cause air conditioner ice formation. These obstructions and leaks cause airflow problems similar to clogged air filter issues. A freezing evaporator coil can lead to system damage when ignored.
Faulty Thermostat
Ice buildup may occur due to a faulty thermostat. The thermostat must accurately detect your home’s temperature for proper system cooling. System components may freeze if the thermostat doesn’t signal the AC to turn off properly.
Blower Fan Malfunction
Your AC’s blower fan pushes air over the evaporator coil and throughout your home. A malfunctioning fan may reduce airflow, freezing excess moisture around the evaporator coil. Regular professional AC maintenance can help prevent this.
As you can see, various issues can cause air conditioners to produce ice. In most scenarios, a professional technician needs to fix the underlying issue. If you need help fixing your air conditioning system, contact Ireland Heating & Air Conditioning Co. in Lake Forest, IL today.
