What kind of equipment?*

Silver flexible HVAC ducts and an air handler sit in a wood-framed attic filled with loose-fill fiberglass insulation.

Seven months of heating pushes dust through the same ducts

Furnaces here run October through April, seven months of the year, on nights that average 30°F through the winter. Every time the system kicks on, air moves through the same runs, and dust that has settled in them gets stirred back into the house.

Storms add to the strain. Robertson County has seen 11 winter storms and 126 damaging wind events over the past ten years, and power interruptions often come with them. A system that shuts off and restarts unevenly pushes more of that settled dust through the ducts each time it comes back on.

7 months: October through April, your furnace pushes air through your ducts
5 months: May through September, your air conditioner does the same

How often should air ducts be cleaned?: There is no fixed schedule that fits every home, so a contractor should look at the ducts before you commit to a date. Dust coming out of the vents, a musty smell when the air handler runs, or a recent renovation are all reasons to have them checked sooner. If anyone in the house has allergies or you have pets that shed, dust and debris build up faster and it is worth checking more often. Homes with pests or visible mold in the ducts should have them cleaned regardless of when the last cleaning happened.
Is air duct cleaning worth it?: It is worth it when there is a real reason behind it, like dust coming out of the vents, a musty smell when the air handler runs, or a family member whose breathing gets worse indoors. Ducts that look clean and cause no symptoms do not need to be cleaned just to be cleaned. A contractor can look at the ductwork and tell you whether cleaning will actually help your air or just cost you money.
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 ducts, then pulls it out through the vacuum. The supply and return vents get cleaned too, and often the coil and blower housing near the furnace or air handler since debris collects there as well. The system is put under negative pressure during the cleaning so the dust gets pulled out rather than pushed further into the ducts or back into the room.
