Constantly recleaning dust from your furniture? Or do you notice a musty smell that shows up only when the system runs? These issues point to buildup inside the ductwork itself, not just the filter. Patriot Heating, Cooling and Air Quality provides air duct and vent cleaning for homeowners throughout Fenton, MO.

Signs Your Ducts Need Cleaning
There are a few tell-tale indications that you need an air duct cleaning service.
- Dust or debris blowing out of vents when the system starts up
- A musty or stale smell that shows up only when the heat or AC runs
- Allergy or asthma symptoms that ease up when family members are away from home
- Visible dust rings or dark streaks around vent covers and returns
- Some rooms feeling dustier or stuffier than others, even with a fresh filter
Older homes around Gravois Bluffs and the Fenton river bottom areas often still run original ductwork from the 70s and 80s, holding decades of buildup. Two or three of these signs together usually means it's time for a look. It's important to note that the EPA advises homeowners (opens in a new tab) to ensure the company offering duct cleaning is qualified to clean all the components.
Our Process
- Walkthrough. We check your vent count, duct material, and access points.
- Containment setup. We connect negative pressure equipment to the main trunk line so loosened debris pulls into containment instead of blowing into your rooms.
- Agitation. We use brushes and air whips to knock buildup loose inside each duct run.
- Vent cleaning. Every supply and return vent gets cleaned individually, cover included.
- Equipment check. We inspect the blower compartment and coil area, since dust builds up there too.
- Walkthrough. We show you before and after so you can see the difference.

For homes with original galvanized ductwork from the 70s and 80s, we often run a camera scope through a section first to check for rust, gaps, or old insulation debris before pulling equipment into the house. This is mechanical cleaning, brushes and airflow, with no chemicals sprayed into your air stream. Most visits run a few hours depending on your duct layout and how many returns you have.
Cost
Cost depends on your home's duct system: how many supply and return vents you have, whether you have one HVAC zone or more, how accessible the ductwork is, and how much buildup we find. A single-story home with one furnace costs less to clean than a two-story home with a finished basement and a second zone. We can usually give you a price over the phone.
