Bobby, the truly simplest approach is to relocate the unit outside the
living space. My parents had central vacuums in their homes since the
first ones were introduced. There were three scenarios of their
installations. (1) Garage, (2) Basement, (3) Spare Closet, where the
interior walls of the closet were heavily insulated. Another
possibility
would be the attic.

In an attic installation, how much performance is lost with an uphill
pipe run?


I have no statistics, but I can't imagine much would be lost. I've know a
couple of families where their installation was in the attic. These homes
had no basements nor free space on the main floor. I don't recall anyone
mentioning a problem.

Consider that many, perhaps most, HVAC air handlers are in the basement,
yet the air easily reacheds the 2nd or even 3rd floor of houses. Perhaps
not a great comparison, but true nevertheless.
