NO

Not acceptable in my area. Local codes prohibit the installation of trees within 6' of any HVAC equipment.

Why sure, but usually, you plant more shrubs around it....

Adds curb appeal, and avoids that ugly industrial gray look!

I figure the tree was here first........

I also figure it could be camoflaged better with some olive drab paint. A good Faux Finisher could paint it to look like a shrub itself!

Is that chicken wire? Or is that for the ivy to wrap around?

It looks to me like the one unit is an evaporative cooler that's on its way to the dumpster, having been replaced by the AC unit behind it.
Is the "swamp cooler" even connected, or was this just a convenient place to store it?

FWIW: Some years ago, I visited East Berlin. I noticed many multi-story buildings, damaged in the war, had accumulated so much grit on their roofs that trees had taken root.
So, it's conceivable that someone might find this on a rooftop some day.
