Tallahassee runs the air conditioner most of the year, and the ducts show it

Your air conditioner runs nearly every month here, with only a short stretch of cooler nights from December through February to give it a break. All that air moving through the ducts carries dust, pollen, and whatever else gets pulled in, and it settles in the bends and joints where the airflow slows down.

Storms add to it. Leon County has seen 473 damaging wind events over the past ten years, and wind like that can drive debris into vents and loosen duct connections. When the power goes out, which happened to over a third of Florida households at some point in 2024, the system sits idle and any moisture in the ducts has time to settle into the dust already there. Over time that buildup restricts airflow and gives the whole system more to push against.

How often should air ducts be cleaned?
Most homes do fine having their ducts checked every few years rather than on a strict schedule. If anyone in the house has allergies, or there's been a pest problem or water damage near the ducts, it's worth checking sooner. A contractor can look inside the supply and return ducts and tell you what condition they're actually in rather than going by the calendar alone.
Is air duct cleaning worth it?
It depends on what's in the ducts. If you can see dust building up at the vents, if the system kicks up a musty smell when it starts, or if someone in the house has allergy symptoms that ease up when they're away from home, cleaning is worth doing. If none of that is happening, the ducts are probably doing their job and cleaning them won't change much. A contractor can inspect the ductwork and tell you honestly whether there's enough buildup to matter.
What does air duct cleaning involve?
A contractor connects a vacuum system to the ductwork and uses brushes or air tools to knock loose dust and debris from inside the duct walls, then pulls it out through the vacuum. Every supply and return vent gets opened and cleaned, and the main trunk lines get the same treatment. The furnace or air handler often gets cleaned at the same time, since it's part of the same airflow path. The filter isn't part of this, since it catches what's in the air rather than what's built up in the ducts themselves.
