Off-Season Air Conditioning: How To Keep It Up

Certain times in the year, you need to look after the maintenance of your heating and cooling unit. Usually, for springs, the air conditioners are the prime concerns, and when fall hits, you must think about your heating system arrangements. Another matter is about the outside air conditioning unit and to put it in a cover during the winter season or leave it without any covering.

Covering your A/C

You need to cover your air conditioner after the end of summer, and it does not necessarily mean you do it for the winter season. Your unit outer covering is hard to deflect damages that comes from rain and snow; however, it is not a cover that will keep the outside unit safe from leaves, debris, or seeds.

So it is better to prepare for the fall season and have a cover ready. “If leaves and other elements like dust and seed enter the air conditioner, they will settle in the system and attract moisture that can lead to the corrosion of the AC system,” says Reliance Air Services. It can also add up and block any drainage moisture system you have installed.

Make sure you only cover the top of the air conditioner. When making the cover by yourself, it should not go over 6 inches down the side. If you end up covering the unit entirely, it may lead to other problems as it will not allow any air to get in and will lead to the formation of corrosion and rust.

Why You Should Not Cover the Air Conditioner

People are in practice to cover things to keep it clean and safe from outside elements like dirt and water. You can see people covering law chairs, swimming pools, or other outdoor furniture regularly. If you are wondering whether you should have a cover for the outside of your air conditioner, the answer is it is not necessary to cover the outside arrangments of air conditioners by any means.


When switched on, the unit absorbs in air, which also takes in the dust. Once it is switched off, it is highly unlikely for the atmosphere dust or other trash will go in.

Snowfall, Frost, and Cold Weather

Outdoor cooling systems are made to survive these severe wintertime climate situations, which excludes the requirement for a cover.


Mist or moisture from the water can halt the AC condenser coils, and this can result in damages with time. However, it is not possible to control the moisture 100%, and it is most likely that some moisture will settle in because of humidity or the wind. The cover will trap this moisture and will lead to the formation of mold, so it is better to avoid using the covering altogether.

Rodents and Small Animals

You are wrong if you think a cover will keep small animals at a distance, in fact, it is most likely that small rodents like rats or insects take shelter in the sheets and make it their winter home. What’s worst is that these animals can even find the resting spot comfortable enough to nest and can then try to find ways into your home!

All in all, you should understand that the ACs have a specific design, and they contain a structure to help the system from the winter climate.
