It is common here for a house to have central air through most of it and a window or through-wall unit in a back bedroom, an enclosed porch, or a room that got added later. Those rooms were never on the duct system, so they get no filtered supply air at all, and the door between them and the rest of the house usually stays shut to keep the window unit's cold in. As far as the central system is concerned, that is part of the house it no longer serves. Which rooms are actually on the ducts is the first thing the walkthrough settles, because an owner whose complaint is about the back room needs to hear that the ducts are not the reason.
The return is the other thing to understand in these houses. Most were built with one large grille in a hallway ceiling or a hall wall, and everything the system draws has to find its way back to that single point. When bedroom doors are shut, and in a full house they usually are, the air has to get out under the door, which it does badly. The hallway return ends up doing all the work and carrying all the dust, while the rooms sit slightly pressurized and pull air in around the windows instead. That is why the hall grille goes gray while the supply registers still look fine.

What sets us apart
Every Supply and Return Line, Not Just the Vent Covers
Wiping a register cover makes the vent look better and changes nothing about the air coming through it. We clean the system behind it — every supply and return line, one at a time — with a high-powered negative-air vacuum that has HEPA filtration, so the dust and debris we dislodge get carried out of the house instead of scattered back into your rooms. Sanitization and vent-cover cleaning are there as add-ons, and we tell you what each one actually does before you decide.
