Highlights:

Step 1: Remove Debris and Straighten Fins

Trim back plants and debris around the condenser. Remove bushes, trim branches, and make sure that everything is out of its way so the condenser can readily breathe. Bushes should be kept at a distance of 2' around and 4' across the top.

Make sure the fins on the coil stand up true. If these get bent, they'll block airflow. Using a piece of flatware or a fin comb, carefully straighten any fins.

Step 2: Check and Level the Condenser

Check and make sure the condenser is level.

If the condenser is off level, put a piece of pressure-treated lumber underneath one side to bring it back level.

Disconnect the power and rinse the condenser thoroughly with the garden hose, making sure to remove all loose debris that might have fallen on the unit.
