A few days ago I posted a message about running wires through a cold air
return. Here's more info about the problem. I have some exterior lights on
the second story of my house that I want to install. I need to run power to
the lights and of course add a switch. If I call an electrician, would
he/she be able to run wire down to the basement to the panel and then
install a switch on the first floor? Or, would they tap into a hot wire in
the attic and install a switch on the second floor?

Yes...

They would do what/whichever was most appropriate/necessary.

Unless the lights are massive, it would seem likely adding them to an
existing nearby lighting circuit would be the logical solution, but
pulling to a first story switch location may still be some effort of course.

All depends on particulars of actual house, locations of panel, junction
boxes, etc., etc., etc., ...
