Reasons For A Freezing Air Conditioner

  • Low refrigerant levels: Refrigerant is the chemical substance that circulates through your AC unit and removes heat from the air. If your refrigerant levels are low, it can cause the evaporator coils to freeze. Low refrigerant levels can cause leaks in the system or incorrect installation. It is better to have an HVAC professional refill the refrigerant and fix any leaks to prevent them from happening again.
  • Dirty air filters: Dirty air filters can restrict airflow, causing the evaporator coils to freeze. The air filter’s purpose is to trap particles such as dust and dirt from entering your air conditioning system. When the filter becomes dirty, it can no longer trap particles efficiently and can cause the air conditioner to freeze. You should regularly change your air filters and have your AC system cleaned by a professional.
  • Blocked air flow: If the airflow is blocked due to a clogged air filter or other obstruction, it can cause the evaporator coils to freeze. This can be caused by furniture blocking vents, ducts, or dirty air filters. It is necessary to ensure vents and ducts are clear and regularly change your air filters.
  • Faulty evaporator coils: If the evaporator coils are dirty or damaged, it can cause them to freeze. This can result from normal wear and tear or a lack of maintenance. To resolve this issue, you should have your evaporator coils cleaned or replaced by a professional.
  • Thermostat issues: If your thermostat fails to function correctly, it may cause the evaporator coils in your air conditioner to freeze. This can be due to a malfunctioning thermostat or a problem with the wiring. It is recommended to have your thermostat inspected and repaired by a professional.
  • Leaking ducts: If your ducts are leaking, it can cause your AC to work harder to circulate air, leading to the evaporator coils freezing. Damaged or worn ducts can cause this. Hire our professional for AC service in Murrieta, CA, to inspect any leaks in your duct system.
  • Clogged drain lines: When the drain lines are clogged, it can cause water to back up and freeze, which can cause the evaporator coils to freeze as well. An escalation of dirt and debris in the drain lines can cause this. A professional should inspect and clean your drain lines to resolve this issue.

Understanding these common reasons why your AC may be freezing and taking the necessary steps to resolve the issue can ensure your AC runs smoothly and efficiently. If you need further assistance, contact the Millar Heating & Air experts for AC repair in Murrieta, CA.
