Ice on an Air Conditioner Is a Sign of Potentially Serious Trouble

An air conditioner that freezes up frequently can be a frustrating inconvenience, requiring you to shut down the unit to give it time to defrost. However, this situation can also lead to more serious problems if the underlying issue isn’t resolved. 

Several mechanical issues can cause your unit to freeze.

Avoid Operating an AC Unit with a Refrigerant Leak

If your system has a refrigerant leak, the pressure in the AC unit will drop. This will lead to lower temperatures that cause freezing. 

It’s important to have a technician evaluate the leak right away. A refrigerant leak usually means there’s corrosion or damage in the lines, and they will need replacing.

Check for a Dirty Evaporator Coil

Another reason to schedule immediate air conditioning maintenance in Thousand Oaks, CA, for a freezing unit is that the cause may be a dirty evaporator coil. Since a dirty coil produces less airflow, the system will freeze up, and ice crystals will form.

A dirty coil also draws more electricity to operate. This can cause too much stress on your system’s compressor and lead to costly damage. In some situations, it’s actually cheaper to replace a damaged compressor.

Schedule Air Conditioning Maintenance in Thousand Oaks, CA, to Repair Mechanical Failure

Additional mechanical issues may be causing your coupling system to freeze up and form ice, such as a broken valve, damaged fan, or a problem with the blower motor. Even a blocked drain line can lead to a congested system that will keep freezing.

Check for Minor Problems First

In some cases, poor airflow is the issue. You may only need to replace or clean a dirty air filter. If the air filter is clean, a problem in your ducts may be causing the issue with the airflow. Your HVAC technician can also inspect your ducts for damage and blockages.
