Plainsboro’s fall humidity drop means dust and allergens cling tighter to your air ducts. The question we hear most this time of year isn’t ‘How much does air duct cleaning cost?’, it’s ‘Why does my system still push dust after cleaning?’ The short answer: Dirty return vents or a clogged filter. Here’s what Plainsboro homeowners need to check before booking another service, and how to avoid wasting money on repeat cleanings.
The Dust Keeps Coming: What Plainsboro HVAC Techs Actually See
If your vents blow dust after cleaning, the problem isn’t the ducts themselves, it’s usually blocked return vents or a full filter. In Plainsboro’s older homes (especially near Route 1), tight ductwork and forgotten registers trap debris. Pro tip: Walk through your home with a flashlight and check every vent cover. If one’s closed or missing, that’s where dust gets trapped. Fix it first, or your next air duct cleaning won’t last.
