With cold weather on the horizon in San Jose, you may be wondering when you should cover your outdoor air conditioner. Of if you have to cover it at all.
Your AC unit is a tough piece of equipment. It’s created to take on bad weather, including extreme temperatures and torrential precipitation.
Sometimes covers create more issues, because they can trap water. Extra wetness inside your unit can cause internal parts to rust or turn moldy.
While putting on an air conditioner cover is an individual choice, there are two seasons that are great for using a cover for an extended period of time—fall and summer.
That’s because yard debris during those seasons—grass clippings, twigs and leaves—can build up and obstruct your system’s airflow. Reduced airflow means your air conditioning unit works more and may use more electricity to cool your residence.

How to Choose an Air Conditioner Cover
If you come to the conclusion you want to cover your air conditioner, here are a couple ideas on selecting the right cover.
Avoid Full Covers
To keep air circulating, a protective air conditioner cover should only encompass the top of your equipment and a few inches on the side.
Total AC covers can trap moisture inside your equipment, potentially eating away at metal pieces. It could also make your system a welcoming area for rodents, which could sever wires.
