An air conditioner fins are part of the condenser that moves warm air away from the unit while running. It looks like a grill with metal fins all along with it. The condenser coil fins can easily bend because they are so delicate.

The AC units still work well with a few bent fins, but heavily bent or damaged ones will restrict the airflow and affect the unit’s efficiency.

When the air conditioner fins are bent, more heat is trapped within the condenser. It was similar to when the unit gets clogged. The unit will work harder and longer to cool off your home, which means a decrease in efficiency for the entire HVAC system.
