Let’s say you were to ask a friend whether you should cover your outdoor AC unit during the winter or keep it uncovered. Don’t be surprised if the answer is “Yes.”
Your response would be something like: “Hey, that wasn’t a yes or no question, let’s try either or.” But your friend, who would just be messing with you, would point out that there are pros and cons to either approach – which means there’s no unanimous choice for which advice to follow.
So, here are the pros and cons of covering and leaving the unit uncovered to help you decide based on facts:
Why You Shouldn’t Cover the AC Unit
- Moisture could become trapped in the system which would create a high humidity environment. That could lead to rust and corrosion. Electrical wiring also can become damaged.
- Your air conditioner is made to be open to the air. Covering your air conditioner will block proper air flow which can lead to mold growth on the evaporator coils. Mold can end up decreasing your system’s operating efficiency.
- Rodents and other animals seek shelter from harsh winters and will often start to inhabit a covered air conditioner. This can lead to other problems like chewed electrical wires and uninsulated refrigerant lines due to the rodents stripping them to make a nest.
- Most manufacturers do not recommend covering your A/C unit. Air conditioners that operate year round are built to withstand an outdoor environment and don’t require coverage.
Why You Should Cover the AC Unit
- It keeps your air conditioner coils a little cleaner for a slight boost in efficiency come the next cooling season.
- Keeps leaves, sticks and other yard waste out.
- Helps prevent water from directly resting on your coils and freezing, which could cause damage.
