Outages and storms let moisture sit in your ducts

Nearly half of Louisiana households went at least 24 hours without power at some point in 2024, and East Baton Rouge Parish has logged 100 damaging wind events over the past ten years. Each time the power goes out, the air handler stops moving air, and whatever moisture is already in the ducts has nowhere to go.

That standing moisture is what lets mold and dust collect on the duct walls. Once it is there, the system pushes it through the house every time it runs, through the five months of the year homes here need heat and every day the air conditioner runs the rest of the year.

How often should air ducts be cleaned?
There's no set schedule that fits every home. Homes with pets, a smoker, or someone with allergies tend to need it more often than homes without. If you've had recent duct work done, water damage, or you notice dust coming out of the vents even after changing the filter, that's a reason to have them looked at sooner rather than waiting.
Is air duct cleaning worth it?
It's worth it when there's a real reason behind it, not just as routine maintenance. If registers are blowing out visible dust, you've had rodents or a water leak in the ductwork, or a family member's allergies flare up worse indoors than outdoors, cleaning solves a real problem. Ducts that look clean and cause no symptoms don't need it just because time has passed.
What does air duct cleaning involve?
A contractor connects a vacuum system to the ductwork and uses brushes or air whips to knock loose dust and debris off the interior walls of the ducts, pulling it out through the vacuum. The supply and return vents, the main trunk lines, and the coil area near the furnace or air handler all get attention. Afterward, a new filter goes in so the system isn't pulling the same dust back through right away.
