This time of year, we have a lot of customers asking us if they should cover their air condenser unit, the part of the air conditioner that sits outside, for the winter. Many air conditioner manufacturers specifically warn customers not to fully cover their units when the weather gets colder, and we tend to agree. Here are some of the reasons why:
Moisture can get into your air conditioning unit from wind, humidity, snow or rain. Fully covering your condenser will trap that moisture inside, which can lead to corrosion, mold and rust.
You may think that a cover will keep rodents away from your air condenser but actually, the opposite is true. Completely covering your unit can create a warm winter home for small animals such as mice and squirrels. They may even end up chewing through wires, causing an even bigger problem.
AC units are designed to sit outside all year long. They are made to withstand harsh sunlight, cold temperatures, snow, wind, rain and ice so there is truly no need to protect them from these elements.
The solution: quarter air condenser covers
Because there is a risk of debris, such as leaves or nuts in the fall or icicles in the winter, falling on or into the air condenser and damaging it, we suggest a partial cover. By covering only the top quarter of your air condenser, you are effectively preventing damage without any of the risks associated with a full cover.
If you are in the market for a partial cover or have any questions about your air condenser, feel free to give Crown Group Ohio a call!
