I got it this way, if it was up to me I would like in on the shady side, but I have to make due with what is.
Planting shrubs in the area is not practical as it is a 8 ft walkway from the kitchen to the backyard, with a hill starting after the 8 ft somehting like:
Where the | of the h is the house and the rest of the h is the a/c unit. the _ is the walkway and the / is the start of the hill.
I was considering some fencing around it, but wondering if the restriction of airflow vs blocking the sun would help or hurt. I was also considering planting some trees on the hill, but that might take years (for me to buy and plant the trees, then I suspect some time for them to grow too ;))
Would it really make a diference if the unit was in the shade, and is it worth the effort?
