Common Reasons Why Your AC Freezes Up

If you live in Murrieta, CA, and are experiencing a frozen air conditioner, you’re not alone. AC freezing is a common problem that many homeowners face, and it can be frustrating. At Millar Heating & Air, we understand the importance of a well-functioning cooling system, so we’ve compiled a list of common reasons why your AC might freeze up. By identifying the root cause, you can prevent further damage and ensure your AC operates efficiently. Call us for superior AC repair in Murrieta, CA.

  1. Dirty Air Filters: One of the most common culprits behind AC freezing is dirty air filters. When filters become clogged with dust, dirt, and debris, they restrict airflow, causing the evaporator coil to freeze. Regularly replacing or cleaning your air filters is essential to maintain proper airflow and prevent freezing issues.
  2. Low Refrigerant Levels: Refrigerant is responsible for cooling the air in your AC system. If the refrigerant levels are too low due to a leak or improper installation, the pressure inside the system drops, leading to freezing. It’s crucial to have a professional HVAC technician inspect your AC system and fix any leaks before recharging the refrigerant.
  3. Blocked Air Vents: Obstructed air vents restrict the airflow in your AC system, causing the evaporator coil to freeze. Ensure that all vents are clear from furniture, curtains, or any other objects that could impede airflow. Additionally, make sure your vents are open and not blocked by dust or debris.
  4. Faulty Fan Motor: The fan motor is responsible for circulating air over the evaporator coil. If the fan motor malfunctions or operates at a low speed, it can cause the coil to freeze. A qualified HVAC technician can diagnose and repair any issues with the fan motor to restore proper airflow.
  5. Improper Thermostat Settings: Incorrect thermostat settings can also contribute to AC freezing. The evaporator coil may freeze up if you set your thermostat too low or leave it in the “on” rather than the “auto” mode. Ensure that the fan is on “auto” and that your thermostat is adjusted to a comfortable temperature.
  6. Blocked or Dirty Evaporator Coil: Over time, the evaporator coil can accumulate dirt and debris, hindering proper heat exchange. This can result in the coil freezing. Regular professional maintenance, including coil cleaning, is essential to prevent this issue.
  7. Issues with the Defrost Sensor: AC units have a defrost sensor that detects ice buildup on the evaporator coil. If the sensor malfunctions, it may not initiate the defrost cycle, causing the coil to freeze completely. Any issues with the defrost sensor can be identified and fixed by a qualified technician.
