Illinois winters are notorious for their extreme cold, heavy snowfall, and icy conditions. While your HVAC system works tirelessly to keep your home comfortable during these harsh months, your outdoor HVAC unit can be particularly vulnerable to ice buildup. Ice accumulation not only reduces the efficiency of your system but can also cause significant damage if left unchecked. At Design-Air Heating & Air Conditioning in Decatur, IL, we’ve been helping homeowners protect their HVAC systems since 1977. In this blog, we’ll share five proven strategies to prevent ice damage to your outdoor HVAC unit and ensure it operates smoothly throughout the winter.
Ensure Proper Drainage Around the Unit
One of the leading causes of ice buildup on an outdoor HVAC unit is poor drainage. If water from melting snow or ice collects around the base of your unit and refreezes, it can lead to significant damage. Ensuring proper drainage is a critical step in preventing ice accumulation. Start by checking the area around your unit for standing water or poor grading that allows water to pool. Make adjustments to the landscape if needed, such as sloping the ground away from the unit or installing a drainage system. Clearing snow and debris from the base of the unit can also improve water flow and reduce the risk of refreezing. If you notice persistent drainage issues, a professional HVAC technician from Design-Air Heating & Air Conditioning can assess the situation and recommend solutions to keep your system safe.
Keep the Unit Free of Snow and Ice
Heavy snow and freezing rain can easily cover your outdoor HVAC unit, blocking airflow and increasing the risk of ice buildup. Regularly clearing snow and ice from the top and sides of your unit is an essential maintenance task during the winter months. Use a soft-bristle broom or a plastic shovel to gently remove snow, taking care not to damage the delicate fins and coils. Avoid using sharp tools or heavy force, as these can cause dents or other damage. If ice forms on the unit, never chip it away with a sharp object; instead, pour warm (not hot) water over the ice to melt it safely. Keeping your unit clear not only protects it from ice damage but also ensures it operates efficiently.
Inspect and Maintain the Unit’s Defrost System
Most modern HVAC systems are equipped with a defrost cycle to prevent ice buildup. This system temporarily reverses the flow of refrigerant to melt ice on the outdoor coils. However, if the defrost system isn’t working correctly, ice can accumulate and lead to serious damage. To ensure your defrost system is functioning properly, schedule regular maintenance with a qualified HVAC technician. During a maintenance visit, the technician will inspect the defrost timer, control board, sensors, and reversing valve to ensure everything is in working order. If your unit doesn’t have a defrost system, consider upgrading to a model that includes this essential feature.

Install a Protective Cover or Shelter
A protective cover or shelter can shield your outdoor HVAC unit from direct exposure to snow, ice, and freezing rain, helping to prevent ice buildup and damage. However, it’s important to choose a cover or shelter designed specifically for HVAC units to avoid restricting airflow. Protective covers made of breathable materials are ideal, as they allow moisture to escape while keeping snow and debris out. If you prefer a more permanent solution, a custom-built shelter can provide year-round protection. Ensure the shelter has an open design that doesn’t obstruct airflow or interfere with the unit’s operation. A Design-Air Heating & Air Conditioning technician can advise you on the best protective measures for your specific HVAC system and climate conditions.
Schedule Regular HVAC Maintenance
Routine maintenance is one of the most effective ways to prevent ice damage to your outdoor HVAC unit. During a professional inspection, a technician can identify potential issues, such as refrigerant leaks, malfunctioning components, or poor drainage, that could contribute to ice buildup. Addressing these problems early can save you from costly repairs down the line. At Design-Air Heating & Air Conditioning, our NATE-certified technicians perform thorough maintenance checks to ensure your system is ready to withstand winter’s challenges.
