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

While air conditioners are built to endure temperature fluctuations, covering them in winter is advisable to prevent the entry of leaves, wildlife, and dirt. Moisture accumulation, a common consequence of uncovered units, can lead to rust and corrosion. It’s recommended to cover the top of the device if moisture is a concern and avoid covering the sides.

Preventing Freezing:

To prevent outdoor air conditioners from freezing, homeowners can:

1. Check for Freon leaks and address them promptly.
2. Regularly inspect and replace the air filter to ensure proper airflow.
3. Clean the condensate line to prevent clogs and overflow.

Running the air conditioner with the cover on may impede airflow, leading to condensation and heat buildup, potentially damaging internal components. Pouring hot water into a frozen air conditioner is not recommended, as it can cause cracks; instead, thaw the evaporator coil with warm water or a hair dryer.


In conclusion, using an air conditioner cover during winter is a wise precaution to ensure the longevity and efficiency of your unit. By selecting a suitable cover and following preventive measures, you can protect your air conditioner from the adverse effects of cold temperatures and environmental elements.
