Frequently Asked Questions
Do I really need to cover my air conditioner during the winter?
Yes, covering your unit prevents debris accumulation like leaves and twigs from entering the fan assembly. It also stops heavy ice from forming on delicate coils. Protecting your unit helps it start efficiently when spring temperatures return.
Can I leave the cover on if I accidentally turn the unit on?
Never operate your air conditioner with the cover in place. Doing so restricts airflow, which can cause the compressor to overheat or fail entirely. Always double-check that the cover is removed before you switch on the power.
Is it better to cover the entire unit or just the top?
A full-coverage design offers the best protection against moisture and rodents. While top-only covers stop falling debris, they leave the sides vulnerable to wind-driven rain. Full covers act as a complete seal against the harsh winter environment.
How do I clean my AC cover?
Use a mild soap solution and a soft cloth to wipe away dust and bird droppings. Avoid using harsh chemical cleaners that might degrade the waterproof coating. Let the cover air dry completely before you fold it for storage.
What should I do if my cover collects standing water?
Check your cover for sagging areas where water might pool. You can often fix this by tightening the fastening straps to create a steeper pitch. If the cover is too large, it might be time to replace it with a better-fitting model.
