Frequently Asked Questions
Do I really need a cover for my central air unit during winter?
Yes, using a cover protects your condenser from snow, ice, and debris. Debris like leaves or twigs can clog the fins, while trapped moisture leads to long-term rust. It is a small investment that adds years to the life of your equipment.
Should I cover the entire unit down to the ground?
Most experts recommend covering only the top portion of the unit. Covering the sides completely can trap condensation inside, which creates a breeding ground for corrosion. Leave the bottom area open to ensure proper airflow while keeping the fan blades shielded.
Can I leave the power on while the unit is covered?
You must disconnect the power before placing a cover on your unit. If someone accidentally triggers the thermostat, the air conditioner might attempt to start while blocked. This could lead to a blown fuse or serious damage to the compressor.
How do I clean my air conditioner cover?
Simply wipe it down with a mild soap and water solution when you remove it in the spring. Avoid using harsh chemicals that might degrade the waterproof coating. Let the material air dry completely before folding it for storage.
What happens if water gets trapped under the cover?
Trapped moisture is essentially a ticking time bomb for your metal components. If you notice water pooling inside, remove the cover immediately to let the unit dry out. Always ensure your chosen cover has adequate ventilation to prevent this issue from recurring.
