Tips for Winterizing and Storing Your Window AC Unit

As the winter season approaches, it’s time to start thinking about how to properly store your window air conditioning unit. Failing to do so can result in damage and a shorter lifespan for the unit. Here are some tips on how to properly store your window AC unit for winter.

Step 1: Remove Unit from Window

The first step in storing your window AC unit is removing it from the window. Make sure that you turn off the power supply before detaching the wires or unplugging it from the wall outlet. Once detached, carefully remove any screws or bolts holding the unit in place and gently lift it out of its housing.


Ensure that you have a helping hand when removing a large-sized AC unit as they can be quite heavy.

Step 2: Clean Your Unit Thoroughly

Cleaning is an essential part of preparing your AC unit for storage. Dust and debris buildup can lead to mold growth, which can cause health problems when not cleaned correctly. Use a soft brush attachment on your vacuum cleaner or wipe down with a damp cloth – ensuring that all areas are free of dust and dirt.


Pay extra attention to areas around filters, coils where debris may accumulate over time.

Step 3: Drain Excess Water

Before storing your AC units away, ensure that you drain excess water by tilting the machine slightly forward so any remaining water flows out through drainage holes (located outside) at its base. This helps prevent water build-up inside during storage, which could potentially damage internal parts like motors if left unattended over time


If there’s still standing water present after draining excess liquid – consider using compressed air (or shop vac)to blow out trapped moisture completely.

Step 4: Cover and Protect Your AC Unit

The next step is to cover and protect the unit from potential damage. Use a fitted cover – one that’s designed specifically for your model of air conditioner – as it will provide better protection against harsh weather conditions during winter months. You can also use blankets, large plastic bags or tarpaulins in case you don’t have an appropriately sized cover.


Ensure that all components are covered properly including the control panel, fan blades, vents, and any other parts that could potentially be exposed to moisture or debris during storage.

Step 5: Store Your AC Unit in a Safe Place

The final step is storing your window AC unit in a safe place where it won’t get damaged over time. Avoid areas with high levels of humidity or dampness; instead, choose dry locations such as basements (if they’re not prone to flooding), garages or attics (provided they’re adequately insulated). Make sure that the storage area is free from extreme temperatures since these can cause cracks on delicate components like plastic housings.


Keep your stored units off floors because moisture tends to seep up easily into electronics if placed on concrete flooring.

By following these simple steps, you can keep your window AC unit in good condition throughout its lifespan – saving you money by avoiding costly repairs due to neglecting basic maintenance tasks. Stay warm and worry-free this winter season knowing your air conditioning system will be protected until needed again!
