Why Is My AC Freezing Up? How To Fix It?

Is your air conditioner freezing up? Don’t worry; you’re not alone. Many homeowners encounter this issue, and it can be frustrating. In this article, we’ll explore the reasons why your AC might be freezing up and provide some tips on how to fix it. If you’re experiencing AC problems in Mesa, AZ, Klee’s Climate Control is here to help. We specialize in AC installation, air conditioning repair, and HVAC repair in Mesa, AZ.

Why Is Your AC Freezing Up?

There are several possible reasons why your AC is freezing up. Let’s take a look at some of the most common causes:

  • Dirty air filters: A dirty air filter can restrict airflow, causing the evaporator coil to become too cold and freeze up. It’s important to clean or replace your air filters regularly to prevent this issue.
  • Low refrigerant levels: Refrigerant is responsible for cooling the air in your AC system. If there’s a leak or insufficient refrigerant, it can lead to the freezing of the evaporator coil. A professional HVAC technician can check and recharge your refrigerant levels.
  • Faulty blower motor: The blower motor is responsible for circulating air over the evaporator coil. If it’s not functioning properly, it can cause the coil to freeze. An HVAC technician can inspect and repair the blower motor if necessary.
  • Blocked or restricted airflow: Obstructions in the air ducts, vents, or around the outdoor unit can restrict airflow, causing the evaporator coil to freeze. Make sure there are no obstructions and that the vents are open and unblocked.
  • Thermostat issues: If the thermostat is set too low or if it’s malfunctioning, it can cause the AC to run continuously, resulting in the freezing of the coil. Check the thermostat settings and consider replacing it if needed.

How To Fix A Frozen AC:

If you notice that your AC is frozen, here are some steps you can take to address the issue:

  1. Turn off the AC: Switch off the air conditioner to prevent further damage and allow the ice to melt.
  2. Check the air filters: Inspect the air filters and clean or replace them if necessary. Clean filters promote proper airflow and prevent the coil from freezing.
  3. Check for airflow restrictions: Ensure that there are no obstructions in the air ducts, vents, or around the outdoor unit. Clear away any debris or objects that may be blocking airflow.
  4. Thaw the coil: Let the ice on the coil melt naturally, or use a fan to speed up the process. Do not try to manually chip away the ice, as this can damage the coil.
  5. Schedule professional service: If the problem persists or if you’re unsure about performing any repairs yourself, it’s best to contact a professional HVAC technician. They have the expertise and tools to diagnose and fix the underlying issue.
