St. Martin Parish weather puts a lot into your ducts

Breaux Bridge sees plenty of damaging wind, 24 events over the last ten years. Wind like that drives dust and debris into attics and crawlspaces, and your return ducts pull it straight into the system. It settles inside the duct runs and blows back into the house every time the blower kicks on.

Power doesn't always stay on through these storms. Close to half of Louisiana households lost power for a day or more in 2024, and a system sitting off during a humid stretch gives dust and moisture time to settle together in the ductwork. Once that layer builds up, the air moving through your home picks some of it up every time the furnace or air conditioner runs.

How often should air ducts be cleaned?
Most homes do fine with a cleaning every few years, not on any fixed yearly schedule. If someone in the house has allergies, or pets shed into the return vents, cleaning more often is worth it. After construction or renovation work, get the ducts cleaned once the dust from that job settles, whenever the last cleaning was.
Is air duct cleaning worth it?
It depends on what your ducts are actually doing right now. If dust is building up around the vent covers, or a room never gets enough air even with a fresh filter, cleaning will help. If nothing looks or smells off and airflow is even room to room, there is no real benefit to cleaning on a schedule alone.
What does air duct cleaning involve?
A contractor connects a vacuum system to the ductwork and uses brushes or 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 this way, and the vent covers usually get wiped down or washed. The furnace or air handler and the coil often get checked too, since dust in the ducts tends to settle there as well.
