What Lamar County weather leaves in your ducts

Sumrall gets 101 damaging wind events and 3 winter storms in a decade. Every one of those pushes outside air into your house through whatever gap it can find, and a good share of what rides in on that air settles in the ductwork. The furnace only runs November through March here, five months a year, so when it does kick on, it's pushing months of settled dust back through the house on the first cold night.

Mississippi households lost power for 24 hours or more at a rate of 30% last year, often tied to the same storms that stress the ducts in the first place. A duct system already carrying buildup has less room for air to move, and that makes the furnace work harder to get the house back up to temperature once the power and the heat are both back on.

How often should air ducts be cleaned?
Most homes do fine with a duct cleaning every three to five years. If anyone in the house has allergies, or you've had work done that left drywall dust or insulation debris behind, it's worth doing sooner. Homes that had a rodent or pest problem in the ductwork should also move that timeline up.
Is air duct cleaning worth it?
Yes, when there's a real reason for it. Dust, pet hair, and debris built up in the ducts get pushed into every room each time the furnace or air conditioner runs, so clearing it out helps with air quality and can cut down on dust settling on furniture. It's less about a fixed schedule and more about whether you're seeing dust buildup at the vents or noticing more of it in the house than usual.
What does air duct cleaning involve?
A contractor uses specialized vacuum equipment and brushes to dislodge and remove dust, debris, and buildup from inside the supply and return ducts. They'll typically clean the vent covers and registers too, and check the coil and blower compartment since debris collects there as well. The whole system stays connected during the process so nothing gets pulled loose or left open to the house.
