I know a city in California with the heat exchangers on the roof. Do you have any idea why? (The properties were large enough the footprint wouldn't be an issue.)

Where I am in the USA Midwest the heat exchangers are all on the ground as they are easier to install and maintain.

    Looks and maybe energy efficiency (if done correctly) would be the biggest reasons I can think of.

    The roofs were hot. I expect ground level in the shade of the house would be better for efficiency.

    Perhaps it had something to do with the location of the indoor unit? I am used to them in the basement or first floor, but some places put them in the ceiling.
