What sits still in your ducts most of the year
Your furnace only runs November through March here, five months a year. The rest of the time, the ductwork sits mostly still, and dust settles into it undisturbed. When the furnace finally kicks on for a cold night, it pushes that buildup through the house before the air clears.
St. Landry Parish has logged 52 damaging wind events over the past ten years. Wind like that can work at duct seams and joints, loosening them enough to pull in dust from the attic or crawlspace. Nearly half of Louisiana households went at least 24 hours without power in 2024, and outages like that leave the system idle even longer between runs, giving dust more time to settle before air moves through it again.

- How often should air ducts be cleaned?
- Most homes do fine having their ducts cleaned every few years, not every year. If anyone in the house has allergies, or you have had pets, a pest problem, or work done on the ductwork, it is worth checking sooner. A roof leak or storm damage can also push dust and debris into the system faster than normal use does. A contractor can look at the ducts and tell you whether they need cleaning now or can wait.
- Is air duct cleaning worth it?
- It depends on what is going on in your ducts. If you can see dust building up around the vents, or the air coming out smells musty, cleaning will make a real difference. If the ducts are in decent shape and the filter has been changed on schedule, cleaning them will not do much you can measure. A contractor who inspects the ducts first can tell you honestly whether it is worth doing in your case.
- What does air duct cleaning involve?
- A contractor connects a vacuum system to the ductwork and uses brushes or compressed air tools to loosen dust and debris from inside the duct walls, then pulls it out through the vacuum. Every supply and return vent gets cleaned, along with the main trunk lines. The furnace or air handler often gets attention too, since dust collects around the blower and coil. A house with more registers takes longer to clean than a smaller one.
