Will Frozen AC Fix Itself?

No, a frozen AC unit will not fix itself. However, being able to identify the signs and causes of frozen AC coils can help all homeowners prevent this issue.

Frozen AC Coil Causes

There are multiple ways coils may become frozen on AC units. Let’s take a look at the most common reasons why this happens below.

Restricted Airflow

The most common cause is restricted airflow within the unit thanks to either blocked vents or dirty air filters. When airflow is ultimately reduced, the condensing coils can become too cold, which causes condensation to freeze on them.

Refrigerant Leaking

A refrigerant leak can also be responsible for frozen coils. Refrigerant will circle through the coils, and leaking can cause the pressure to drop. The resulting decrease in pressure can cause your coils to become quite cold. This eventually leads to the buildup of ice.

If you notice any of these signs, it’s crucial to address the issues promptly in order to prevent any further damage to your AC unit. Ignoring frozen coils can lead to decreased efficiency and increased energy consumption.

More severe problems, such as compressor damage, can also develop from these symptoms. Always address frozen coils in a timely manner with the help of an experienced AC repair team in your area.

Will A Frozen AC Fix Itself?

A frozen AC unit will not fix itself, as mentioned above. If your unit is frozen, it’s essential to turn it off immediately and allow the ice to thaw out. Doing so as soon as you notice an issue can potentially save the compressor from any harmful damage.

Once the unit has thawed completely, the root cause of the freezing should be identified and repaired by the professionals. Leaving a frozen AC untreated for a lengthy amount of time can lead to more serious issues, including compressor failure.

How To Fix Frozen AC Coils

The first step in attempting to fix the frozen coils is to turn off your AC unit. Continuing to run the AC while the coils are frozen could lead to further damage. Next, check for any airflow issues that may be causing the freezing. Check your air filter first to ensure it is clean.

Dirty or clogged air filters can obstruct the flow of air. Either clean or replace the air filter, if necessary. In addition, check if there are any obstructions found around the return registers or air vents.

Thawing the coils carefully is the most important step here. Refrain from trying to speed up this process with the use of heaters or hairdryers. Instead, it’s recommended to let the coils defrost naturally. This process could take a full overnight to complete.

How To Prevent An AC System From Freezing

Regular maintenance of your AC unit is an essential piece of preventing frozen coils. During professional maintenance service, the experienced team can ensure your unit is running properly, while also cleaning coils and checking refrigerant levels.

Proper airflow and insulation are crucial aspects of preventing any freezing. Make sure all registers and vents are unobstructed and open.

Always set your thermostat to a moderate temperature range to avoid any freezing. Staying away from cold temperatures can potentially lead to the formation of ice on the coils.
