What six months of heating and 306 wind events leave behind in your ducts

Your furnace runs November through April here, six months of pushing air through the same ductwork. Every one of those cycles moves whatever is sitting in the ducts, dust, lint, anything that settled since the last run, and pushes it into the rooms of the house.

Clark County has logged 306 damaging wind events over the past ten years. Wind that strong works dust and debris into any gap or loose seam in a duct system, and once it is inside, heating and cooling cycles keep circulating it rather than clearing it out.

6 months: November through April, your furnace pushes air through your ducts
6 months: May through October, your air conditioner does the same

How often should air ducts be cleaned?: There's no fixed schedule that fits every home. If anyone in the house has allergies, if you notice dust coming back quickly after cleaning, or if you've had remodeling work done, it's worth having them checked sooner rather than later. A contractor can look inside the ducts and tell you whether there's actually buildup worth removing, rather than cleaning on a calendar just because time has passed.
Is air duct cleaning worth it?: It depends on what's happening in the ducts. Visible dust blowing out of the vents, a musty smell when the system runs, or buildup you can see at the register are signs that cleaning solves a real problem. If none of that is happening, cleaning them on a schedule alone does not do much. A contractor can inspect the actual ductwork and tell you whether there's anything worth taking out.
What does air duct cleaning involve?: A contractor connects a vacuum system to the ductwork and uses brushes or air tools to loosen dust and debris from inside the duct walls, then draws it out through the vacuum. Registers and grilles get cleaned on their own since they collect their own dust. The furnace or air handler often gets checked too, since every bit of air moving through the house passes through it first.
