Troubleshooting Guide: How To Fix A Frozen Outdoor Air Conditioning Unit

During the summer, your air conditioning unit works tirelessly to ensure you stay cool and comfortable. However, what happens when your outdoor air conditioning unit freezes up? This can be a common problem, but not knowing what to do can lead to costly repairs. Here is a list of steps you can take to troubleshoot and fix a frozen air conditioning unit before calling in the professionals.

Shut off the unit:

If you notice your air conditioning unit has frozen, the first thing you should do is turn it off. Leaving the unit running could cause the compressor to become damaged. The fan may keep running, but that’s okay, as it can help to thaw the system out faster.

Check for airflow obstruction:

Insufficient airflow in your air conditioning unit can lead to freezing. Check your air filter to see if it’s dirty or clogged. If it is, replace it with a new one. You should also make sure that there aren’t any obstructions near your outdoor unit, such as overgrown bushes or grass, that could be blocking airflow.

Inspect the refrigerant level:

Low levels of refrigerant will cause your unit to freeze up. Holes or leaks in the refrigerant line can also cause a drop in pressure, leading to decreased refrigerant levels. If you suspect low refrigerant levels, contact a professional to recharge your system.

Examine the evaporator coil:

A dirty evaporator coil can lead to the freezing of your air conditioning unit. Cleaning the coil is a simple fix that can be done yourself. Simply turn off the power to your unit and then clean the coil with a soft-bristled brush or vacuum. You can also purchase special cleaning solutions to clean the coil.

Contact a professional:

If the above steps don’t fix the problem, it’s time to call in a professional. There could be a more significant problem to consider, like a malfunctioning compressor or a refrigerant leak that requires attention from a licensed technician.

Don’t let a frozen air conditioning unit ruin your summer. By following these instructions, you can diagnose and resolve the issue on your own or determine when to seek assistance from a professional. Remember to turn off the unit, check for airflow obstruction, inspect the refrigerant level, examine the evaporator coil, and contact a professional if needed. Regular care and maintenance can significantly contribute to the efficiency of your air conditioning unit through the summer season.
