What Livingston Parish weather leaves behind in your ducts
Livingston Parish sees power go out and come back more than most places. Nearly half of Louisiana households lost power for at least a day in 2024, and this county has logged 59 damaging wind events over the past ten years. Every time the system shuts down and starts back up, it pulls in whatever settled in the ducts while the air was still.
Most homes here are single-family and owner-occupied, and heat only has to run from November through March. The rest of the year the ducts sit warm and often damp, which is when dust and debris cling to the inside of the duct walls instead of blowing through. That buildup narrows the path the air has to travel, so the system works harder to push the same air through the house.

- How often should air ducts be cleaned?
- There is no fixed schedule that fits every house. It depends more on what is happening inside than on the calendar. Pets, a recent renovation, or a musty smell coming from the vents are reasons to have them looked at sooner. If nobody in the house has allergy trouble and the vents look clean when you pull a register off, there is no rush.
- Is air duct cleaning worth it?
- It is worth it when there is a real reason behind it, not just as routine upkeep. If a register is coughing out visible dust, if recent work left drywall dust or debris in the system, or if you can see buildup when you look inside a duct, cleaning solves a problem you can point to. Cleaning ducts that are already in decent shape will not make your furnace run better or lower a power bill, since that gain comes from a clean filter, not clean ducts. A contractor can look at your system and tell you whether there is enough buildup to matter.
- What does air duct cleaning involve?
- A contractor connects a vacuum to the duct system and uses brushes or air tools to knock dust and debris off the inside of the duct walls, then pulls it out through the vacuum line. Every supply and return register gets opened up and cleaned. The furnace or air handler, including the blower and coil, usually gets attention at the same time since that is where a lot of the buildup starts. The job is done when air can move through the system without carrying that buildup into the rooms of the house.
