Proper maintenance of your central AC unit during winter is not as straightforward as simply turning it off until spring.

Homeowners who adopt this method may inadvertently jeopardize one of the most essential and costly appliances in their homes.

While central AC units are designed for outdoor use, this does not mean they can withstand harsh weather conditions without some assistance.

For instance, heavy snowfall and the subsequent melting as temperatures rise can lead to moisture accumulation inside the unit, fostering corrosion and mold growth.

Additionally, large debris falling from trees during severe storms can damage the fins on top of the unit, resulting in expensive repairs.

However, professionals often advise against complete coverage due to potential issues it can cause, such as trapping moisture inside the unit.

The humidity and warmth generated by this full coverage create an ideal environment for pests during the cold winter months, which could result in electrical damage as they gnaw through wiring.

This humidity and warmth can also accelerate corrosion and mold growth, but at a much quicker pace than an uncovered unit, as the moisture has no outlet.

Fortunately, there is a balanced solution that lies between these two extremes, and a $7 product from Home Depot is an excellent way to achieve it.

A Tempered Hardboard Project Panel from Home Depot, measuring 4 feet long by 2 feet wide by 1/8 inch deep, can cover the top of your AC unit while keeping the sides exposed, as experts recommend.

This method will prevent heavy debris from trees from damaging the fins on top of the unit and stop snow from entering the unit as it falls.

Exposing the sides of the unit will also permit moisture to escape, preventing the creation of an inviting environment for rodents and other pests.
