What power outages leave behind in your ducts
Heat runs in Lafayette Parish from November through March, on nights that average 44 degrees. That is not a long season, but it is enough to matter when something goes wrong with the system pushing air through your house.
Almost half of Louisiana households lost power for a day or more in 2024, and the parish has logged 39 damaging wind events over the past ten years. Each time the system sits idle during an outage, dust already in the ducts settles instead of moving through. When the power comes back and the air starts moving again, that settled dust goes with it, into the rooms you're heating.

- How often should air ducts be cleaned?
- There is no fixed calendar for this, since it depends on what is going into the ducts. Homes with pets, a smoker, or someone with allergies tend to need it sooner, because more gets pulled into the return air and settles inside. If you had duct work done recently, or you can see dust building up around the vent covers, that is a sign to get it looked at rather than wait. A contractor can check inside the ducts and tell you honestly where things stand.
- Is air duct cleaning worth it?
- It is worth it when the ducts actually need it, not on a fixed schedule regardless of condition. Dust, pet hair, and debris built up inside the ducts get pushed into every room when the system runs, so cleaning them out cuts down on what settles on furniture and gets breathed in. It will not fix a musty smell coming from mold in the coil or a drain pan, and it will not lower a heating bill on its own. A contractor can look inside the ducts and tell you honestly whether cleaning will help your situation.
- What does air duct cleaning involve?
- A contractor connects a high-powered vacuum to the duct system and then agitates the inside of each duct run with brushes or air whips to knock loose dust and debris free so the vacuum pulls it out. They work through the supply and return ducts, the grilles and registers, and usually the coil and blower compartment too, since dirt collects there as well. The job is done when air moves through the whole system without stirring up what used to be stuck to the duct walls.
