How to Properly Store Your Window Air Conditioner for Winter

Winter is fast approaching, and it's time to bid farewell to those scorching summer days. But what about your trusty window air conditioner? Properly storing your AC unit during the winter months is essential to ensure it stays in peak condition for the next cooling season. In this guide, we'll walk you through the steps to store your window AC correctly, keeping it damage-free and ready to deliver cool comfort when the sun returns.

Step 1: Choose the Right Storage Location

To begin, select a suitable indoor location for storage. Your air conditioner should be stored in a dry and cool place to prevent damage from moisture or extreme temperature changes. Avoid uninsulated areas like garages, crawlspaces, and sheds. We recommend finding a cozy spot indoors to keep your AC safe.

Step 2: Locate the Original Box

If you have the original box and packaging materials that your air conditioner came in, that's fantastic! These materials are designed to protect your unit during storage. If you don't have the original box, look for a sturdy cardboard box that closely matches the size of your AC unit. Don’t forget to leave space for accessories like the remote control and side panels.

Step 3: Power Down and Unplug

Before storing your air conditioner, ensure it's powered down completely. Use the power button or remote control to turn it off, and then unplug it from the electrical outlet. 

Step 4: Remove Any Attachments

If your air conditioner has detachable parts or accessories, such as side accordion panels, carefully remove them. These components should be stored alongside the air conditioner in the box. Ensure they are properly secured to prevent damage.

Step 5: Clean the Air Conditioner

Allow the unit to cool down if it has been recently used. Use a soft, damp cloth to gently clean the exterior, removing any dirt or dust buildup. For a deeper clean, you can refer to our video guide linked here.

**Important:** Before proceeding to the next step, make sure the air conditioner is completely dry. It's crucial to allow it to air out for a full 48 hours before storage.

Step 6: Position the Air Conditioner in the Box

Pack the detachable parts, accessories, and the user manual inside the box alongside your air conditioner. Ensure everything is secured properly to avoid damage during storage. Carefully place the air conditioner inside the original or suitable replacement box. It should fit snugly to prevent movement. Never wrap the unit in a tarp or garbage bag, as this can trap moisture. Always store it upright, never on its side or upside down.

Step 7: Store the Remote Control

If your air conditioner comes with a remote control, remove the batteries before storing it. This prevents potential corrosion. Remember to use fresh batteries when you bring it out next summer.

Step 8: Seal the Box

Close the box securely and seal all seams and edges using packing tape. This step ensures that dust and debris won't find their way inside during storage.

Step 9: Elevate the Air Conditioner

Place your air conditioner on a clean and dry surface. To protect it from moisture damage, elevate the unit slightly off the ground using wooden blocks or other suitable supports.

During the winter, periodically check the air conditioner to ensure there's no moisture buildup inside the box. If you notice any issues or damage following summer, contact a technician before using the unit again.

By following these easy-to-follow steps, you'll keep your window air conditioner in tip-top shape, ensuring cool comfort when the warm weather returns. Stay practical, stay informed, and remember, we're here to help you with all your home comfort needs.
