Rooftop installation

[suzan4379]

I am having a ductless unit (Mitsubishi Slim Jim) installed on the upper floor of my house. I have very limited space for installation of the outside unit except for my flat roof. I have been reading discussions on this site that it is a really, really bad idea to have a unit installed on the roof but they did not outline the reasons against it. Is it just a safety issue? or are there other reasons?

Thank you for any assistance.

Just noise and possible vibrations.Why can't you put it on ground level?

My exterior wall is 2' away from my neighbors and there are mostly windows on the ground level. I live in a highly populated downtown area and don't have much ground space to speak of. Also, I am worried that someone might steal it if it too accessible.
P.S. Thanks for getting back to me so quickly.

If this is a urban townhouse with a flat commerical type roof... then I don;t see a problem. And it's probaly a good idea for the reasons you stated. We have several mini splits on the roof of our industrial buildigs. They aren't any worse off than those at groudn level. Actually they've proven far more durable than conventional splits with their inverter driven compressor.
