Construction Dust, Not Age
Drywall sanding, sawing and finishing work produce fine dust, and open supply boots and return ducts collect it during construction. NADCA advises new-home buyers to have the ductwork inspected, because a new system is often less clean than it looks. Guidance from the EPA and the Department of Energy's building science program calls for sealing duct openings and keeping the system off during dusty work.
| What you see | What it points to |
|---|---|
| Filter turns gray within weeks of move-in | Construction dust moving through the system |
| Fine white dust on furniture near vents | Drywall dust in the supply runs |
| Debris visible inside a floor register | Material dropped into an open boot |
| Dust after a basement finish or remodel | New dust from the project |

Check the Builder Paperwork First
Homes finished in the last few years may still be within the builder's warranty period. Read the warranty and the closing documents before paying for duct work, and photograph any debris you find in a register. If the builder declines, an inspection gives you a written record of what is in the ducts.
Brambleton or Ashburn on the Envelope
Brambleton homes use ZIP code 20148, and many carry Ashburn mailing addresses. Brambleton is its own census-designated place in Loudoun County, with Broadlands to the north and Arcola to the south. Its housing is younger than most of the Ashburn area, where homes date mostly from the 1990s and 2000s.
Townhome Dryer Vents and Gas Furnaces
Townhomes make up 46 percent of Brambleton's housing. Upper-floor laundry rooms send the dryer exhaust through long runs or the roof, and those runs collect lint faster than a short wall vent. Cleaning typically costs $135 to $360. Eight in ten homes heat with natural gas, so a carbon monoxide alarm on every level and a yearly furnace check apply here too.
