Central Air Conditioning Unit and Heat Pump Maintenance

If your condensing unit has coils that are bent, they should be straightened out as much as possible for proper performance of the unit. You cannot straighten the fins properly without a special tool called a fin comb. These tools come in a variety of styles including single, multiple or interchangeable heads having different fin comb sizes and counts to best match the coil fin size of the repaired unit. Some six sided head models will work for 8, 9, 10, 12, 14 and 15 fins per inch coils.

To straighten the bent fins, match the teeth count of the comb to the fins per inch of the coil. Then carefully draw the comb across the bent coil fins straightening them out in the process.

Replace the grille covers and screws.
