I bought a house that has a central air vac system. The system is not
functional so it needs to be replaced. There is a conduit / outlet in each
room.

Here is a pic of the vac unit in the garage:

I think there should be a hose to be attached to the room outlets. I wonder
if I need to replace the unit and the hose, do I need to get the original
brand (Nutone) or any brand will work?

Thanks,

MC
