Wind and outages move air through your ducts too
Rapides Parish sees a lot of wind. The record here shows 59 damaging wind events over the past ten years, next to just one winter storm. Wind that strong pushes air into a house through every gap it can find, and ductwork that runs through the attic or under the floor picks up dust and debris right along with it.
Nearly half of Louisiana households lost power for a full day or more in 2024. When the power drops, the system stops pulling air through the filter, but the house doesn't stop moving dust and pollen indoors. That settles in the ducts and waits for the system to come back on and push it through the house again.

- How often should air ducts be cleaned?
- Most homes do fine with a cleaning every few years. If anyone in the house has allergies, or you have pets shedding into the return vents, you might want it sooner. After any work on the ductwork itself, like a repair or an addition, that is also a good time to have them cleaned out.
- Is air duct cleaning worth it?
- It depends on what is actually in the ducts. If a contractor opens a vent and finds dust buildup, pet hair, or signs that pests have been living in there, cleaning is worth doing. If the ducts look reasonably clear, cleaning them will not improve your air or your furnace's performance by much. A contractor can look at your system and tell you which situation you are in before any work starts.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system, then uses brushes or compressed air tools to knock loose dust and debris from inside the metal so it can be pulled out. They work through the supply and return lines room by room, and check the coil and blower housing since debris tends to collect there too. The vents themselves get wiped down as part of the job.
