We have the condensing unit of our AC system on the south side of the house (it was the most convenient place). It gets a lot of direct sun during the day, and I hear that your AC's efficiency can be reduced by 10% if the condensing unit is in the direct sun. Should I make a type of shade cover or something and attach it to the fence? The distance of the fence from the house is about 4 feet, and the fence is 6 feet high.
