What is an AC System?
Your air conditioner operates through a series of interconnected parts that each play a vital role. The compressor is at the heart of the system, which moves refrigerant to capture and release heat. The outdoor condenser coils release this heat into the environment, while the indoor evaporator coils help cool the air inside your home. Meanwhile, the expansion valve ensures proper refrigerant flow control between these components.
These parts are built for durability, using corrosion-resistant materials such as galvanized steel and aluminum. They are designed to endure extreme cold and exposure to the elements.
Because of this resilience, the exterior components of your AC system can typically manage winter weather on their own, without the need for added protection.
Why Some Homeowners Choose to Cover Their Cooling Units
Some homeowners opt to cover their AC units during winter in an effort to keep out debris like leaves and guard against snow and ice buildup. Their goal is to prevent obstructions and mechanical issues that could reduce efficiency or result in expensive repairs. This approach is particularly popular in areas that experience strong winds or significant snowfall.
Still, the advantages of covering an AC unit in winter are often misunderstood. Although a cover can reduce the buildup of leaves and other debris, it may also trap moisture inside, increasing the risk of rust and corrosion over time.
Covers may also attract pests like rodents, which can nest within the unit, chew on wiring, or obstruct airflow. When considering whether to use a cover, it’s important to balance the short-term protection with these possible risks to your system.

Potential Issues from Covering Your Outdoor AC Unit
While adding a cover may appear to offer extra protection, it can actually create conditions that harm your cooling system.
Moisture Buildup and Resulting Damage
When an AC unit is covered, moisture can become trapped inside, creating the ideal environment for rust and corrosion to form on vital metal parts. Because most covers limit ventilation, they prevent moisture from escaping, whether it’s from condensation or melting snow, resulting in excessive dampness within the unit.
Continued exposure to moisture can lead to rust and encourage the growth of mold and mildew. These issues may extend into the unit’s internal components, reducing its performance and efficiency. If mold spores enter your home through the system, they could also affect indoor air quality and contribute to potential health concerns.

Pest Infestation Risks
Using a cover in winter can unintentionally invite rodents and insects by providing a protected space away from the cold. These pests may build nests inside the unit, chew through electrical wiring, obstruct airflow with nesting materials, and leave droppings that compromise system cleanliness and function.
Infestations can cause serious harm to internal components, leading to expensive repairs or reduced system lifespan. They may also introduce health concerns, as contaminants left behind by pests can be dispersed through your home’s air when the system runs again in warmer weather.
Reduced Performance and Energy Efficiency
When an AC unit is covered, moisture buildup and pest activity can severely affect its operation. Moisture corrosion can weaken essential components, lowering cooling performance, while pest activity can lead to damaged wiring and restricted airflow.
These complications may lead to premature wear, forcing the system to work harder and consume more energy. As a result, utility bills rise, and the cost of repairing or replacing damaged parts may outweigh any initial benefits of using a cover.

Effective Methods to Prepare Your Air Conditioner for Winter Without a Cover
You can protect your air conditioner throughout the cold season by following a few practical steps that help maintain its condition and keep it running efficiently come spring.
Schedule Post-Winter Cooling System Maintenance
Once winter ends, professional maintenance is essential to restore peak performance. This service typically includes a detailed cleaning to eliminate debris such as leaves and dirt that may have gathered around the unit. Clearing this buildup helps maintain steady airflow and prevents unnecessary stress on system components.
During this inspection, technicians should assess key parts of the system, including refrigerant levels, electrical connections, and the condition of both evaporator and condenser coils.
Addressing these areas in advance improves energy efficiency and allows for early detection of developing problems, reducing the chance of unexpected breakdowns and helping the system last longer.
Other Ways to Safeguard Your HVAC System in Winter
Instead of using a full cover, consider other methods that offer protection without encouraging moisture retention or pest intrusion:
- Top-Only Cover with Breathable Fabric: Shielding just the top of the unit with a breathable material helps block snow and falling debris while allowing airflow around the sides. This minimizes the chances of trapped moisture that can cause internal damage.
- Install on a Raised Base: If possible, have the unit positioned on an elevated platform. Lifting the base above ground level helps clear snow buildup and prevents moisture-related issues from melting ice or pooled water.
Also, make it a habit to clear away leaves, branches, and other debris surrounding the unit throughout the season. After snowfall, carefully remove snow from the top and sides to avoid ice buildup, which can block airflow and place extra stress on the system.
By following these steps, you help preserve the unit’s performance and prevent typical winter damage without exposing it to the risks that come with full coverage.

Insights from HVAC Experts
HVAC specialists, including Lawes Company, frequently advise against placing full covers on air conditioning units during winter. They cite concerns about trapped moisture and the potential for pest infestations.
A study by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) reinforces this view, showing that units left uncovered during winter last about 15% longer and encounter fewer system failures than those that are covered.
The research points to increased corrosion and electrical problems in covered units, mainly caused by trapped moisture and pest activity. Industry experts advocate for alternative methods that safeguard the unit while preserving its performance and safety.

Common Questions About AC Covers
Is It Necessary to Cover My Air Conditioning Unit If It’s Located Beneath Trees?
A full cover is still discouraged, even when the unit sits beneath trees. A better approach is to use a breathable mesh to cover only the top, which helps block falling debris while allowing ventilation to prevent trapped moisture.
Does Covering My Cooling Unit Increase the Risk of Expensive Repairs in Spring?
Yes. Using a cover can contribute to problems such as trapped moisture, rust, and pest damage. These issues often remain hidden until spring, potentially leading to costly repairs once the system is back in use.
How Can I Tell If My Air Conditioner Has Moisture Damage?
Look for visible rust on both the outer casing and internal parts, a persistent musty odor that may suggest mold growth, and any pooling or signs of water inside the unit. These are clear indicators of moisture-related damage.

How Frequently Should I Inspect My AC Unit in Winter?
You should check your outdoor unit at least once per month during the colder months. Clear away snow, ice, and debris, and look for any signs of damage or pest presence to keep the unit in good condition.
Is Any Form of Winter Protection Necessary for A/Cs?
Outdoor air conditioners are built to handle winter weather without a full cover. Routine upkeep, such as removing debris and snow, is typically sufficient. Scheduled maintenance and visual checks provide more reliable protection than enclosing the unit.
Final Thoughts
This article examined the widespread practice of covering air conditioning units in winter. Although some view it as a protective step, full covers often cause more harm than good by trapping moisture, promoting corrosion and mold, and attracting pests. These issues can cause costly repairs and decreased system performance.
A better approach is to use a breathable top cover, routinely clear away debris, and arrange for professional maintenance. Following these guidelines will help safeguard your system and ensure it operates efficiently year-round.
