The usual suspects
Return-duct leaks
Return ducts under negative pressure SUCK air from the crawlspace or attic — then blow that dust into every room.
Filter bypass
A wrong-size filter or gappy slot lets air sneak around the media unfiltered.
A filter too weak for the house
Builder-grade panels stop gravel, not dust. A better media filter changes daily life.
Genuinely dirty supply ducts
Real in older or post-renovation homes — but less common than the marketing says; we verify before selling a cleaning.
Cut the dust at the source.
Return-leak sealing and a proper filtration setup beat any amount of dusting. Options quoted upfront.

Worth trying first (5 minutes, free)
- 1
Check the filter’s fit: gaps around the edges = bypass; note the size.
- 2
Look at return grilles and any duct joints you can see — dust trails at seams mark leaks.
- 3
Upgrade one filter grade as a test (not the maximum — too restrictive chokes airflow).

Quick answers
Would duct cleaning fix it?
Only if the ducts are the source — if returns are pulling from the crawlspace, cleaned ducts re-dirty in weeks. We test for leaks first so you buy the fix, not the ritual.
What filter should I actually run?
The best your blower can breathe through — typically a mid-grade pleated media, sometimes a proper media cabinet. We size it to your system, not to a marketing chart.
Is this an air-quality health issue?
Crawlspace-sourced dust can carry what crawlspaces carry — it’s worth fixing beyond the housekeeping. The check is quick and priced upfront.
Done guessing?
Less dust, cleaner air, happier lungs. Book the air-quality check.
