A fin guard is a protective metal or plastic mesh that covers the delicate aluminum fins on your outdoor unit. It protects the Condenser Coil from hail, garden tools, and curious pets. Many of our Cooper&Hunter units come with integrated guards for added durability. If your unit is in a high-traffic area, a fin guard is a must-have to prevent airflow-restricting damage. You can find various Parts and Accessories to enhance the protection of your outdoor unit. Combined with a Gold Fin Coating, a guard ensures your coils stay in factory condition. Maintaining the integrity of your fins is key to those high SEER2 Ratings. It’s a small investment that prevents costly coil repairs down the road.
