How to tell when your ducts are overdue — from visible dust puffs to unexplained allergies.
Not sure if it's time? Here are the ten telltale signs.
- Visible dust puffing from vents when the system starts.
- Dust settling faster than usual on surfaces.
- Musty or stale odors when the AC runs.
- Unexplained allergy or sinus symptoms at home.
- Uneven room temperatures.
- Rising energy bills with no other explanation.
- Visible mold around registers or in the unit.
- Pest evidence — droppings or nesting material.
- Recent renovation with drywall or sawdust.
- You just moved in and don't know the history.
Any two or more of these? It's time to book a cleaning.
