Types of Hail Damage to AC Units
Hail damage to AC units can range from minor cosmetic issues to more serious functional problems. Here are some common types of hail damage you may encounter:
- Dented or damaged fins on the condenser coil: The delicate aluminum fins on your AC's condenser coil can easily become bent or damaged by hail, which can restrict airflow and reduce the unit's efficiency.
- Damaged condenser fan blades: Hail can also cause the fan blades in your outdoor unit to become bent, cracked, or broken, leading to reduced airflow and increased strain on the motor.
- Punctured or damaged refrigerant lines: In some cases, hail can puncture or damage the refrigerant lines, causing refrigerant leaks and reduced cooling performance.
- Cracked or damaged housing: Hail can crack or damage the housing around your outdoor unit, allowing water, dirt, and debris to enter and potentially damage the electrical components inside.

Preventing Future Hail Damage
While you can't control the weather, there are steps you can take to protect your AC unit from future hail damage:
- Install a hail guard: Hail guards are designed to protect your outdoor unit from hail and other debris. They are typically made of sturdy metal or plastic and can be easily installed by a professional.
- Consider a protective cover: Protective covers can shield your AC unit from hail and other elements when it's not in use, such as during the winter months. Make sure to choose a breathable cover that allows for proper airflow to prevent condensation and mold growth.
- Keep your unit well-maintained: Regular maintenance, such as cleaning the condenser coil and checking for refrigerant leaks, can help your AC unit function more efficiently and reduce the risk of damage from hail and other factors.
