What Causes An AC To Freeze Up?

Air conditioning units are a necessity for many households, especially during hot summer months. However, there may be instances when your AC unit suddenly freezes up, causing discomfort and inconvenience.

In this blog post, we will discuss the common causes of an AC freezing up and how professional services like ac repair in Beaverton and ac repair in Hillsboro from O’Leary Air can help you resolve these issues efficiently. So, let’s dive into the reasons behind this common problem.t

Insufficient Airflow

One of the primary reasons why an AC unit may freeze up is due to insufficient airflow. When there is not enough air passing through the evaporator coil, it can cause the coil to become too cold and eventually freeze. This can be caused by several factors, including:

  • Dirty or clogged air filters
  • Blocked air vents or ducts
  • Malfunctioning fan motor
  • Damaged fan blades

To prevent this issue, regularly clean or replace your air filters, ensure your air vents are unobstructed, and schedule regular maintenance checks with a trusted AC service provider like O’Leary Air.

Low Refrigerant Levels

Another common cause of an AC freezing up is low refrigerant levels. The refrigerant is responsible for absorbing heat from the air and cooling it down. When the system has insufficient refrigerant, the evaporator coil can become too cold and freeze. This can result from the following:

  • Leaks in the refrigerant lines
  • Improper installation or servicing
  • A damaged compressor

If you suspect that your AC unit has a refrigerant leak, it is essential to contact a professional AC repair service like O’Leary Air. Our team of experts can diagnose the problem, provide the necessary repairs, and ensure that your AC unit operates optimally.

Dirty Evaporator Coil

A dirty evaporator coil can also lead to your AC unit freezing up. Dust, dirt, and debris accumulating on the coil can impede its ability to absorb heat effectively. This may cause the coil to become too cold and eventually freeze. To prevent this issue:

  • Schedule regular maintenance checks with a professional AC service provider
  • Clean your air filters regularly
  • Ensure proper airflow throughout your home

O’Leary Air offers comprehensive AC maintenance services, including evaporator coil cleaning, to keep your system running smoothly and efficiently.

Thermostat Issues

An improperly functioning thermostat can also cause your AC unit to freeze up. When the thermostat fails to regulate the temperature correctly, it may cause your AC unit to run continuously, leading to freezing. Common thermostat issues include:

  • Incorrect temperature readings
  • Malfunctioning sensors
  • Wiring problems

If you suspect that your thermostat is not functioning correctly, contact O’Leary Air for professional ac repair in Beaverton or ac repair in Hillsboro. Our team of experts can diagnose and fix any thermostat-related issues, ensuring that your AC unit operates efficiently and maintains a comfortable temperature in your home.

Operating Your AC Unit in Cold Weather

Using your AC unit during cold weather can also cause it to freeze up. When the temperature outside is too low, the pressure inside the system can drop, causing the refrigerant to expand and the evaporator coil to become too cold. To prevent this issue, avoid using your AC unit when the outdoor temperature is below 60°F.
