In my previous house, the AC units were designed to sit on the EAST wall so afternoon sun does not "bother" them. This was done for energy efficiency reason (just common sense, the AC units work against a heat gradient and do not need more heat from the sun).
In my current house, the AC units sit on the WEST wall. This summer was unusually HOT. My electricity bill this summer was very high.
My question is: Has anyone used any technique to shield AC units, particularly those baked by the afternoon sun (On the SOUTH wall or WEST wall)?
- Small trees to cover them?
- Small cedar shed?
