The last owner of my Boler
tried to install one on the roof and yes the roof cracked. Maybe that is why I got a great deal on my egg! So be careful if you go that route. When I did my search on putting a a/c in a egg I wasn't happen with what I saw for me. Window units take away the windows
or space where ever you put them. And let us not forget about the noise. Even roof mount u units make alot of noise.
I went with a split mini unit where I installed the outdoor unit on the tongue (80 lbs) and indoor unit (20 lbs) above the table. This is the best thing I think I could have ever done to my egg. I did lose some cabinet door space. The unit puts out less noise than a table top fan. And since I installed it a couple of weeks ago I found out more bennys from a mini split system. Something to think about!
PS, It is also a 9000 BTU unit. Now tell me I will be getting hot!
