Wind and long winters both work on your ductwork
Doña Ana County has logged 83 damaging wind events over the past ten years. Wind like that pushes dust and grit into a house through every gap around doors, windows and vents, and a lot of it ends up settling in the ducts. Once it's there, it doesn't clear out on its own.
Your furnace runs November through April here, six months of the year, with winter nights averaging 30°F. That's a long stretch pushing air through runs that had all the warmer months to collect what the wind carried in. A duct system that's never been cleaned is carrying years of it, and every time the furnace kicks on, some of that gets pushed back into the air.

- How often should air ducts be cleaned?
- Most houses do fine having this checked every few years rather than on a fixed schedule. Homes with pets, a smoker, or someone with allergies usually need it sooner, since dust and hair build up faster. A musty smell when the furnace kicks on, or dust settling faster than it used to, both mean it is worth having a contractor look sooner.
- Is air duct cleaning worth it?
- It is worth it if the ducts actually have a buildup of dust, pet hair, or debris in them, which a contractor can check before doing the work. Clean ducts mean the air moving through your house all winter is not carrying that buildup back into the rooms. It will not lower your heating bill or fix a furnace problem, so if that is the goal, the issue is likely somewhere else.
- What does air duct cleaning involve?
- A contractor puts each supply and return vent through a cleaning with specialized tools and a strong vacuum, working through the whole system so debris does not just get pushed from one duct to another. The furnace or air handler gets cleaned too, since it connects to every duct in the house. Grilles and vent covers usually come off during the job so the technician can reach inside them.
