Gonzales homes shut their ducts down for long stretches

Heat only runs November through March here, and even then it is mild, with winter nights averaging 44°F. The rest of the year that ductwork sits closed up while the air conditioner does the work instead. Dust and whatever comes in with it settles in the duct runs during those quiet months and gets stirred loose again once the system kicks back on.

Ascension Parish also loses power. Statewide, about half of households went at least a day without it in 2024, and the area has seen 30 damaging wind events over the last ten years. When power drops, the air handler stops pulling air through the filter, and dust in the ducts has more time to settle before the system starts moving air again.

How often should air ducts be cleaned?
There's no fixed schedule that fits every home. Homes with pets, a recent renovation, or someone with allergies may need it sooner than a home without those things. A contractor can check what's actually inside your ducts before you decide anything.
Is air duct cleaning worth it?
It's worth it when there's a real reason for it, like visible dust coming from the vents, a musty smell when the furnace or AC kicks on, or work done on the ductwork itself. It won't fix an allergy problem on its own, and it isn't something to schedule just because time has passed. If you're not sure whether your situation calls for it, a contractor can inspect the ducts and tell you what's actually in there.
What does air duct cleaning involve?
A contractor uses brushes and a high-powered vacuum to loosen and pull dust and debris out of the ductwork. The supply and return vents get cleaned along with the ducts themselves, and the furnace or air handler often gets a look too since it connects to the same system. The point is to get everything out of the ducts, not just push it further down the line.
