No-mess shade tree for A/C unit?
I'm looking for a tree to shade my A/C unit. Of course, I want something that won't make a mess in the unit-- a Cottonwood is off the table of course.
Other points I'd like:
-bird / wildlife feature
-nice fall color
-I don't want it to get too huge
-pretty flowers /smell would be a plus, but not a dealbreaker. :)
Do maples have much mess? Or maybe a crabapple that will hold the fruits for the birds? How about redbuds?
Thanks in advance for any suggestions.
