I have two large compressors installed on the roof of my 4-story apartment building. They are on the roof in the hot sun all day, but we are located at the top of a hill and get a lot of wind and breeze.

Would there be any benefit to shading our A/C compressors? Can we construct a baffle that will provide shade w/o blocking too much air flow? Or should we just leave them alone?

Your comments are appreciated.
