Proper Storage Tips for Window Air Conditioners

Keeping your home cool in the summer months is essential, and a window air conditioner is an excellent option for many people. However, once the colder temperatures arrive, it’s time to store your unit until next year. Properly storing your window air conditioner can prevent damage and ensure that it will work efficiently when you need it again.

Step 1: Clean The Air Conditioner

Before storing your window air conditioner, you should clean it thoroughly. Start by removing any debris or dirt from the exterior of the unit with a damp cloth. Next, remove the filter and wash it with warm soapy water before allowing it to dry completely.

Check The Evaporator And Condenser Coils

While cleaning your window air conditioner, make sure to check both the evaporator and condenser coils for any damage or debris buildup. If there are signs of corrosion or other issues that could impact performance negatively, consider calling in a professional technician.

Step 2: Secure The Unit For Storage

After cleaning and checking over your window AC unit, secure everything in place for storage. You can do this by replacing all screws tightly on each side of its bracket to hold onto brackets securely during transport if needed later.

Protect Against Dust And Debris

Once secured properly into storage brackets against walls or ceilings (if necessary), cover up any exposed areas like vents with paper towels or plastic wrap taped around edges so dust won’t get inside where mold growth may occur over time due to humidity levels within closed-off spaces near windows during winter months.

Step 3: Store In A Safe Location

The final step is finding a safe location for storing your window air conditioner during off-seasons such as winter months when not needing cool indoor air. The best place to store it is where you can keep the unit away from extreme temperatures, moisture, and direct sunlight.

Consider Using A Storage Unit

If you don’t have space to store your window air conditioner safely at home, consider renting a storage unit for added protection. These units are climate-controlled and will prevent your AC unit from being exposed to harsh weather conditions that could damage it.


Properly storing your window air conditioner during off-seasons is crucial for maintaining its performance and extending its lifespan. Following these simple steps of cleaning it thoroughly, securing all parts in place with mounting brackets or screws if needed after removing any debris buildup on coils too – before placing into secure storage spaces protected against dust & humidity levels while avoiding locations with high heat exposure like attics or basements is key for keeping this valuable investment running smoothly year-round!
