A guy who owns a local home inspection business also answers home
improvement questions in our Saturday paper. While describing how to
add an AC system in the attic he wrote:

"Coolant lines and electrical cables to the second or third floors can
often be concealed in sections of gutter downspout material that is
attached to the side of the house."

Anybody ever heard of this? Does the NEC allow allow it?

And, yes, I know he doesn't mean the same downspouts as the ones
attached to the gutters.

We do it all the time. Just make sure the wiring is
rated for outdoor use. UF and SEU cable for instance.
The HVAC supply houses sell a plastic duct system
that is used primarily for mini-split AC units. It could
be used also.
