An air conditioning system is made up of various key parts that are vital for its functioning. At the heart of the system is the compressor, which pumps refrigerant throughout the unit to absorb and expel heat. The condenser coils, situated outside, release the absorbed heat away from the premises. Inside, the evaporator coils work to cool the air within the building while the expansion valve carefully controls the refrigerant flow.
These components are built to endure extreme weather, crafted from materials resistant to corrosion, such as aluminum or galvanized steel, and designed to withstand temperatures below freezing. This robustness indicates that an AC unit’s external elements can face winter conditions without needing extra protection.

The Case for Covering Your Air Conditioning Unit
Numerous homeowners cover their air conditioning units during winter to guard against debris like fallen leaves and to shield against potential damage from snow and ice accumulating on mechanical components. They hold that protecting the unit helps prevent blockages and mechanical damage, which can decrease efficiency or result in expensive repairs. This approach is especially prevalent in areas prone to heavy snowfall or strong winds.
However, there are misunderstandings regarding the advantages of covering an AC unit in the colder months. Although covers can block debris from accumulating, they can also trap moisture, which promotes rust and corrosion.
Moreover, covers can create a welcoming environment for rodents and other pests, potentially leading to electrical damage or blocked airways. When determining whether to cover your unit, balance these protective benefits with the possible risks.
Issues Linked to Outdoor Air Conditioner Cover
Covering your outdoor air conditioner might appear wise, yet this practice can introduce several unintended problems.
Trapped Moisture & Its Implications
Encasing an air conditioning unit often leads to trapped moisture, which can encourage rust and corrosion in critical metal parts. The cover’s lack of breathability impedes the evaporation of condensation or melted snow, creating a moist environment.
Persistent dampness can lead to rust and foster the growth of mold and mildew, which might extend to the internal mechanisms of the unit, reducing its efficiency and possibly creating health risks if spores are dispersed into your home when the unit operates.

Issues with Unwanted Pests
Covering your air conditioner in the winter might unintentionally provide a cozy, sheltered habitat that appeals to rodents and insects escaping the cold. These pests can reside within the covered space, chewing through wiring, obstructing airflow passages with their nesting materials, and fouling the system with their droppings. These infestations can severely damage the unit’s components and pose health risks by potentially spreading contaminants throughout the air system when the unit is turned on in the warmer months.
Compromised Functionality & Efficiency in Air Conditioners
Moisture entrapment and pest infestations in a covered air conditioning unit can drastically affect its functionality and efficiency. Moisture may corrode essential components, reducing the unit’s ability to cool effectively, while pests can damage wiring and block airflow.
These complications shorten the unit’s lifespan and cause a spike in energy use and higher utility costs. Moreover, the significant expenses for repairs and replacing parts can make covering the unit more costly in the long run.
Optimal Methods for Winterizing Your Air Conditioning Unit Without a Cover
Effectively preparing your air conditioning unit for winter without using a cover requires a series of deliberate actions to maintain its longevity and ensure it is operational for the upcoming warm months.
Regular Maintenance of Your Air Conditioner
It is essential to arrange for professional air conditioning unit maintenance before and after winter to guarantee peak performance. Crucial maintenance involves a comprehensive unit cleaning to clear out any accumulated dirt, leaves, and other debris. This ensures that airflow is not obstructed and helps to minimize strain on the system.
Technicians should also inspect the system’s overall integrity, checking components like refrigerant levels, electrical connections, and the evaporator and condenser coils’ condition. This proactive servicing boosts efficiency and aids in the early detection of potential issues, significantly reducing the likelihood of breakdowns and prolonging the unit’s lifespan.
Alternative Protective Measures for HVAC Systems
When preparing your air conditioning unit for winter, explore alternatives to full covers to safeguard the system effectively while avoiding the risks linked to moisture and pests:
- Partial Air Conditioner Covering: Opt for a breathable material to cover only the top part of the unit. This strategy prevents debris and snow from entering the system from above, permitting ample air circulation to prevent moisture accumulation.
- Elevated AC Unit Platforms: Ensure your unit is mounted on an elevated platform whenever possible. This elevation helps to keep the base free from accumulating snow and diminishes the likelihood of water damage from melting snow and ice.
Additionally, it’s important to regularly clear leaves, twigs, and other debris from around the unit. Following snowfalls, carefully remove snow from the top and sides of the unit to avoid ice buildup, which can block airflow and overburden the system. These practices contribute to maintaining the unit’s efficiency and protecting it from common winter-related damages while avoiding the disadvantages of using a full cover.

Professional Insights on HVAC Maintenance
HVAC specialists, such as those at Townsend Energy, strongly discourage using full covers on air conditioning units during the colder months, pointing out the dangers of moisture retention and pest harborage. Research made by the American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) reinforces this position, showing that units left uncovered in winter last about 15% longer and suffer significantly fewer operational failures compared to their covered counterparts.
This research emphasizes issues like accelerated corrosion and electrical malfunctions in covered units, attributed mainly to trapped moisture and pest activity. Instead, experts suggest alternative protective strategies that maintain the unit’s integrity without affecting its operational efficiency or safety.
Frequently Asked Questions About Air Conditioner Covers
Here are some typical inquiries regarding the maintenance of air conditioning units during the winter:
Should I Cover My AC Unit If It’s Directly Under Trees?
Even if your AC unit is directly under trees, fully covering it is not advised. Instead, shield just the top of the unit using a breathable mesh. This allows you to block falling debris effectively while still letting moisture escape.
Does Covering My AC Unit Increase Spring Repair Costs?
Yes, using a cover over your air conditioning unit can increase repair costs come spring. This is due to problems such as moisture damage, corrosion, and pest infestations that often remain hidden until the unit is uncovered and used again in warmer weather.
What Are Some Indicators Of Air Conditioner Moisture Damage To Look Out For?
Look for signs of moisture damage in your AC unit like rust on both external and internal components, a musty odor that suggests mold growth, and any evidence of water pooling inside the unit.
How Frequently Should I Inspect My Air Conditioner Unit During Winter?
We recommend checking your outdoor cooling unit at least once a month throughout the winter. This helps you to promptly remove any snow or debris and check for indicators of damage or pest activity.
Conclusion
This article has discussed the common practice of using an air conditioner coverduring winter and outlined the potential disadvantages, such as moisture entrapment, increased rust and mold growth, and pest infestations. These issues can contribute to higher repair costs and reduced efficiency.
Instead of using a full air conditioner cover, we advocate using breathable top covers, routine maintenance, and regular debris clearing. These steps help to protect your AC unit and preserve its performance, avoiding the drawbacks of full coverage and ensuring it remains functional and efficient year-round.
