Cover or not to cover your AC unit in the winter

October 26, 2023

As the summer months give way to autumn, you may be wondering what many homeowners often do: Should I cover my air conditioning unit?

The short answer: No, you should not cover your AC unit. Your air conditioning unit is designed to withstand winter weather without the need for full enclosures or plastic covers. While it's a common belief that covering your air conditioning unit can protect it from the harsh winter elements, using the wrong type of cover can actually do more harm than good. 

Plastic covers, or any material that restricts airflow, can trap moisture within the unit, creating a perfect environment for rust and internal damage to thrive. When moisture is locked in, it can freeze and thaw repeatedly, potentially causing cracks and damage to critical components. 

It's generally recommended to cover only the top of the unit or use a breathable cover that allows airflow. Breathable covers allow air to circulate while keeping out debris like leaves and twigs, offering a layer of protection without locking in damaging moisture. These covers are designed to strike the right balance between safeguarding your unit and allowing it to "breathe."

Instead of relying on a cover, invest in annual maintenance for your AC unit every spring. This approach ensures that your system is in optimal working condition when you need it most during the hot summer months. Consider signing up for our annual service agreement with our expert team who can provide the care your AC unit deserves.

Ultimately, trust in the durability of your AC unit and focus on proper maintenance to extend its lifespan and keep your home comfortable year-round.
