Newark and Irvington rowhouses were converted to forced air decades after they were built. The supply runs take odd paths through closets and joist bays, and the return side is frequently a single undersized grille doing the work of three.

Maplewood and South Orange have a high share of houses where a finished basement enclosed the ductwork. That hides both the joints and the leaks, so what looks like a cleaning question is sometimes a sealing one.

Livingston and Millburn ranches and splits run long crawlspace or slab trunks. Flexible branch runs sag over decades, and a sagging branch collects everything that passes through it.
