Ten months of running ducts wears on them

Your ductwork moves heated air through the house from September through June here in Hot Springs County. That is ten months of the year the system is on, pushing air through the same runs of duct night after night. On the nights that average 12°F, the furnace runs long and often to keep up, and every run of air carries dust and whatever else is sitting in the ducts back into the rooms you live in.

With 66 winter storms and 68 damaging wind events recorded here over the past ten years, homes in this county see plenty of days with doors and windows sealed tight and the furnace working hard. Dust and debris that settle in the ducts during those stretches get circulated right back through the house, and in a system that runs this many months of the year, that buildup has a lot of time to collect.

How often should air ducts be cleaned?
Most homes do fine with duct cleaning every few years rather than on any set yearly schedule. Homes with pets, a smoker, or someone with allergies often need it more often since dust and dander build up faster in the ducts. If you see dust blowing out of the vents or gathering fast around them after a cleaning, that is a sign to move the schedule up.
Is air duct cleaning worth it?
It is worth it if your ducts actually have a buildup of dust, pet hair, or debris in them, and a contractor can tell you that by looking. Clean ducts mean the air moving through your home for those September through June months of heating isn't carrying that buildup with it. It will not lower your heating bills or fix a furnace problem, so if that is the goal, the ducts are not the place to start.
What does air duct cleaning involve?
A contractor connects a vacuum system to your ductwork and uses brushes or air tools to knock loose dust and debris before pulling it out through the vacuum. Each vent in the house gets opened and cleaned, along with the main trunk lines that run to the furnace. The furnace blower and coil often get a look too, since dust in the ducts usually means dust has built up there as well.
