As winter sets in, homeowners take proactive measures to winterize their homes and shield them from the harsh weather. The air conditioning unit stands out prominently among the various items that require attention. The question arises: is it necessary to cover your AC unit during winter? This practice has both proponents and opponents. This article explores the advantages and disadvantages while providing valuable tips for successful implementation.

Reasons for Covering Your AC Unit During Winter

When winterizing their homes, many homeowners opt to cover their AC units. The first reason is to protect the unit from snow, ice, and debris. Winter weather can be harsh, and the unit can suffer damage if not protected. For instance, heavy snow on top of the unit or a buildup of ice can weigh it down and cause structural damage.


Another reason for covering your AC unit is to prevent corrosion. Exposing your AC unit to cold temperatures can cause metal parts to rust and corrode. This is especially true for areas with high levels of humidity. By covering it, you are protecting it from moisture and preventing corrosion.


Additionally, covering your AC unit can help keep critters out. Animals seek warm shelter as temperatures drop, making the unit an ideal hiding spot. Covering it creates a barrier, preventing small animals from making their home in your AC unit.


Lastly, covering your AC unit can also help improve its lifespan. By protecting it from the harsh winter weather, you are helping to extend its life and avoid costly repairs. For AC repair and maintenance services in Huntingdon Valley and the surrounding areas, AAA Brothers Heating & Air Conditioning provides exceptional service and expertise.

Reasons Against Covering Your AC Unit During Winter

On the other hand, some experts argue against covering your AC unit during winter. The first reason is that it can trap moisture inside the unit, causing damage. If not properly secured, the cover can create a sealed environment around the unit, trapping any moisture. This can lead to corrosion of electrical components.


Another argument against covering your AC unit is that it can provide a hiding spot for pests. Your covered unit may keep critters out but it can also attract them. The warm and dark environment the cover creates can invite pests looking to make your AC unit their home.


Also, covering your AC unit can create a fire hazard. If the cover is not removed before turning on the unit in spring, it could cause a fire when the unit starts up. This is because debris or moisture trapped inside the cover can ignite when exposed to heat. Finally, covering your AC unit may also void the manufacturer’s warranty. Many manufacturers do not recommend using covers as they can interfere with proper airflow and cause damage.

Best Practices for Covering Your AC Unit

If you decide to cover your AC unit during winter, it’s crucial to follow the best practices to ensure the effective protection of your unit without inadvertently causing damage.


Firstly, only cover the top of your AC unit. This method shields the unit from falling debris, snow, or ice while preventing moisture buildup and allowing airflow. An alternative to a full cover is a piece of plywood placed on top of the unit. This can protect the unit from falling ice or heavy snow loads that could cause structural damage.


Secondly, choose materials wisely. Opt for a breathable material that resists mold and mildew. Some covers are designed with a vented panel to allow airflow and prevent condensation, providing an extra layer of protection. Avoid plastic or vinyl covers as they can trap moisture and lead to rust or mold growth.


Thirdly, ensure the cover is secure to stay in place during high winds but not overly tight to limit airflow. Consider covers with drawstrings or straps that help keep the cover in position without cutting off air circulation.


Whether you decide to cover or not cover your AC unit during winter depends on the specific factors of your location and the type of unit. In case you choose to cover it, following some of the tips mentioned above could help prevent damage. The main objective for any homeowner is to have their air conditioning unit last longer while running efficiently when needed.
