Eight months of heating pulls dust through the same ducts
Your furnace runs October through May here, eight months of the year. On winter nights averaging 31°F it cycles on and off all night long, and every cycle pushes air through the same ductwork. Dust, pet hair, and whatever settles in the return air gets carried through those ducts and blown back into the rooms you live in.
Tulare County has seen 149 winter storms and 191 damaging wind events over the past ten years. Storms like these knock out power, and when the furnace shuts off mid-cycle, dust already loose in the ducts can settle deeper into the system instead of getting filtered out. Over eight months of heating, that buildup works its way through the whole house.

- How often should air ducts be cleaned?
- There's no fixed schedule that fits every house. A contractor can look at the ducts and tell you whether they need cleaning now or can wait. If anyone in the house has allergies, or you've had rodents or a water leak near the ductwork, get it looked at sooner rather than later.
- Is air duct cleaning worth it?
- It's worth it if you can see dust kicking out of the vents, smell something musty when the system runs, or know there's debris built up from a past repair or pest problem. It won't fix an allergy or lower a utility bill on its own. A contractor can look at the ducts and tell you honestly whether cleaning will help your situation or whether the problem is somewhere else, like the filter or a leak in the ductwork itself.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork, then uses brushes or air tools to knock loose dust and debris and pull it out through the vacuum. They'll open the supply and return vents to reach each duct run, and check the coil and blower housing since debris collects there too. The furnace filter gets replaced as part of the job, since a clean duct system feeding through a dirty filter doesn't accomplish much.
