Do I Need to Cover My Air Conditioner?

With cold weather coming in Paso Robles, you may be wondering when you should cover your outdoor air conditioner. Of if you should even cover it at all.

Your AC unit is a tough piece of equipment. It’s created to withstand inclement weather, including extreme temperatures and torrential precipitation.

Sometimes covers do more harm than good, because they can trap condensation. Additional wetness inside your unit can cause internal pieces to rust or become moldy.

While installing an air conditioner cover is an individual choice, there are two seasons that are great for using a cover for a long period of time—fall and summer.  

That’s because yard rubbish during those seasons—grass clippings, twigs and leaves—can pile up and block your system’s airflow. Decreased airflow means your air conditioning unit works longer and may use more power to cool your house.

Looking for other ways to make your air conditioner run efficiently? Annual AC maintenance from Paso Robles Heating and Air heating and cooling technicians can help. We’ll clean and lubricate your system, and examine critical parts. This often allows us to spot trouble before they begin.

How to Choose an Air Conditioner Cover

If you determine you want to cover your air conditioner, here are a few ideas on choosing the best 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.

Complete AC covers can trap water inside your unit, potentially corroding metal pieces. It could also make your air conditioner an inviting home for rodents, which could chew wires.

Cover Your Air Conditioner Before Severe Weather

You can temporarily cover your air conditioner in the winter when you know a snowstorm is on the way. Snow and ice that collect inside your AC can melt and refreeze, harming condenser coils and decreasing efficiency.

Although it’s not always possible to predict a hailstorm, you can temporarily cover your AC if a severe storm is approaching in Paso Robles. Hail can seriously damage your system’s exterior, affecting efficiency.
