I have a new construction and for whatever reason the HVAC installers placed the compressor right in front of a bedroom window. I don't have any complaints about the noise (it is actually pretty quiet). Unfortunately, the fan blades reflect sunlight and it produces this annoying strobing effect within the room.
My builder was thinking about spray painting a black matte on the blade, but I'm wondering if there is something more "professional" that they can do to reduce or eliminate the reflection.

I think that it is not appropriate to paint a brand new piece of equipment , painted with electrostatic paint and perfectly finished, for both the aesthetic part and for potential warranty issues.
If I had this problem I would order from a blacksmith a small shelter skeleton and I would put a polycarbonate sheet as a roof (this can be done by a carpenter as well without the need a the polycarbonate sheet).
To get a better idea here is a picture of the concept :
You will of course use a much smaller size to cover only the unit.
