Fix Your AC Fins & Surf Waves of Coolness

Go with the Flow: Clean Fins Beat Rising Bills

Air conditioning fins, or AC fins for short, are thin blades of metal found on both the evaporator and condenser coils of your AC system. They work like shutters to allow the unobstructed flow of heat to be exchanged, from the refrigerant into the air, and vice versa, depending on the air temp and time of year  When fins are bent, crushed, or otherwise damaged, airflow is restricted, and the entire cooling process is compromised.

Even small damage to your AC fins can cost you comfort and money—especially during the days of sizzling summer heat. These thin metal strips maximize how well your system moves heat. If they’re bent, clogged, or dinged up, your AC has to work overtime, creating system strain and higher energy bills.

Why Neglecting AC Fins Hurts You

• Blocked fins → Your AC runs longer, wasting energy.
• Poor heat transfer → The system strains, bills climb.
• Fins that trap dirt → Ice forms, risking major breakdowns.

• Overheating → The compressor (the AC’s heart) could fail.

Fast Fixes for AC Fins

• Straighten gently with a fin comb or flathead screwdriver.
• Clear debris using a soft brush or vacuum.
• Call on Derr. if the damage is bad—DIY mistakes can make it worse.

Keep Fins Happy: Prevent Problems

• Schedule seasonal AC check-ups.
• Visually inspect and clear debris around the outdoor unit.
• Never use a pressure washer on fins—they’re delicate!
