What you say as far as putting the heat pump compressor on the south side of the home is true as far as heat. However since we are using the same unit for cooling you pay back when you are cooling. I've not seen anyone suggest putting a deciduous tree in to shade your compressor in the summer but leave it opened to gather heat in the ????? winter. I would expect you would be regularly need to take the machine apart to get rid of leaves inside of it.
