What to Consider When Buying a Window Air Conditioner Cover What to Consider When Buying a Window Air Conditioner Cover

A window air conditioner cover is essential for protecting your air conditioning unit during the winter or other periods of time when it is not in use. During the off season, the air conditioner is constantly exposed to the outdoor air, leaves, insects, grease and pollution. Over a few months, the buildup of these elements can be significant. As a result, the air conditioner coils may become clogged, and the transfer of heat outdoors becomes affected. To prevent this, you must use a high quality window air conditioner cover. Before buying a cover, consider the following points.

Weather Conditions

There are several conditions you must consider before committing to a particular window air conditioner cover. If you live in an area that experiences severe sun exposure and high levels of ultraviolet rays, you must choose a cover that is resistant to these conditions. Look for a guarantee against fading or discoloration. You will also need a superior quality product if you live near the sea because sea air is more corrosive.

Size and Fit of the Window Air Conditioner Cover

The window air conditioner cover must fit snugly around the unit. It must be made of a heavy duty material such as vinyl, which will last for years without any problems. A cover that is too big or too small will not do the job.

Ease of Cleaning

Ask for cleaning instructions beforehand. Most window air conditioner covers are washable with a mild detergent solution. Cleaners made for vinyl surfaces will also work well. Never put the cover in a washer or dryer, even if the instructions say so. If you do, ensure there is a warranty against shrinkage or damage.

Available Colors

If appearance is important, look for a color that blends in with your surroundings. Some manufacturers offer different colors and even decorative designs on window air conditioner covers.

Level of Moisture Protection

Look for a waterproof window air conditioner cover. Some covers have a waterproof coating sprayed on. This coating may erode and wear off with time. Look for a guarantee of the moisture resistant capabilities of the cover you purchase.

Cross Ventilation around the Unit

Never cover a window air conditioner completely. It is important to leave a gap of about 0.5 inch at the bottom. This will enable air circulation around the unit. In the absence of such a gap, water or moisture around the unit will not have an outlet through which it can escape. The buildup of moisture will cause rusting of the unit.

Available Warrantee

A warrantee of 5 years or more is an indication of a quality product. Look for the best warranty and guarantees on the window air conditioner cover.


Some covers have a tendency to shrink after you wash them. This may make the cover unusable after a very short time. Look for a guarantee against shrinkage so that the cover remains the same size and fit for a long time.
