Is It Necessary to Cover Your Air Conditioner During the Winter?

It is sometimes preferable to cover your air conditioner during the winter. The air conditioner is designed to withstand temperature, rain, and snow changes.

However, it is not intended to keep out leaves, wildlife, or dirt. However, it is best to cover the air conditioner when debris such as insects and leaves can enter the unit in the fall.

It also causes moisture accumulation, which can lead to rust and corrosion. Cover the device, and if moisture is a concern, only cover the top of the device. Avoid covering the sides.

How can I keep the external air conditioner from freezing?

You can do a few things to keep your outdoor air conditioner from freezing. The most common ways to avoid this are as follows:

Check for Freon leaks with a technician.

If the unit is low on refrigerant, ice will most likely form on the coil. This usually happens in the winter when the temperature outside is below 30 degrees Fahrenheit. Refrigerant leaks can cause severe other air conditioning problems, so it is best to request repairs.

Check the air filter regularly.

Proper airflow is required for air conditioners to function correctly.

Suppose the unit becomes clogged or the air filter becomes dirty. In that case, the airflow in the air duct is restricted, resulting in functional issues such as the evaporator coil freezing. Replace the air filter at least every two months, and if you live in a city, replace it more frequently.

Check The Condensate Line

Heat is absorbed and transferred by air conditioners. The water condensed by the air conditioner escapes to the drain pan via the condenser line during this process.

On the other hand, the condensation line can become clogged over time. Excess water flows back into the evaporator coil and freezes when the line begins to overflow. If you suspect the condenser line is clogged, clean it with a diluted vinegar or bleach solution.

What happens if you run the air conditioner while wearing the cover?

Operating the air conditioner with the cover on may impair airflow. This can cause condensation and heat to build up inside the unit, causing damage to the air conditioner’s internal components. There is no way for heat to escape if the cover is left open, and overheating can cause the device to shut down.

Can you pour hot water into a frozen air conditioner?

Although pouring hot water into a refrigerating air conditioner is not recommended, you can pour warm water into the unit to thaw the evaporator coil.

Pouring hot water over your device in the dead of winter can cause cracks. You can also open the coil with a hair dryer.


I hope this post has helped to explain the benefits of using an air conditioner cover and how to use it.

If you’re concerned that your device will freeze due to cold temperatures, take precautions during the fall season, such as checking for leaks and clearing debris around your device.
