Air Duct Cleaning in St. Louis - One Flat Price, Before-and-After Photos

Trusted Air Duct Cleaning for St. Louis Homeowners

If your registers are puffing out dust every time the furnace kicks on, or the air in your home tastes stale no matter how often you change the filter, the source is usually further back than the filter – inside the duct runs themselves. Air duct cleaning in St. Louis pulls that accumulated dust, debris and settled buildup out of the whole system using professional-grade extraction, not a shop-vac on wheels. Our technicians have up to 9 years of experience and work with Rotobrush and Nikro equipment, the same systems used by certified indoor-air contractors. We’re licensed and insured, we agree one flat price per system before any work starts, and we can usually schedule same-day service in St. Louis. Call (877) 349-6189 and we’ll book a free estimate.

Air Duct Cleaning Services

Air Duct Cleaning Services at Bellmont Air Duct Cleaning means a full-system clean: every supply and return run, the main trunk lines, the registers, and the air handler cabinet where dust collects fastest. You need it when you’re seeing visible dust trails at the vents, when a renovation has left drywall dust through the house, when you’ve just moved in and don’t know the last time the ducts were touched, or when allergy season hits harder indoors than out. We hook up negative-pressure containment with Abatement Technologies equipment, run the Rotobrush through each branch line, and finish with HEPA filtration so nothing we loosen ends up back in your living room. Typical air duct cleaning in St. Louis runs $350-$700 for a standard home, and larger or heavily soiled systems run higher. The written estimate you get before work begins sets the final price.

Full-System Extraction

We clean the whole duct network, not just the runs you can reach from a floor register. The Rotobrush whip travels the length of each branch, scrubbing the walls as it goes, while the Nikro vacuum holds the debris stream under control. Once the system is clean, we can show you before-and-after photos of your own ducts so you know the work was actually done.

Containment Done Right

Loosening years of dust without controlling it just moves the problem into your living space. Our Abatement Technologies containment gear keeps the work zone sealed and filters the air we exhaust. That’s the difference between a proper clean and a dust storm with an invoice attached.

HVAC Duct Cleaning

HVAC Duct Cleaning is the part of the job that protects your heating and cooling equipment, because the ductwork is the delivery system for everything your furnace and air conditioner produce. When the inside of those ducts is coated with dust and debris, your blower works harder, your filter clogs faster, and the system that a St. Louis homeowner just paid to install never runs the way it should. We clean the supply and return sides together with the air handler cabinet, using professional-grade extraction and HEPA containment from Abatement Technologies. It’s the right call after a new HVAC install, after a major remodel, or when the system has been running years without attention. HVAC duct cleaning in St. Louis typically runs $400-$800 depending on the size and layout of the system, with the written estimate setting the final number.

Working With Your Equipment

We don’t install HVAC systems and we don’t pretend to be general contractors. What we do is clean and repair the ductwork your equipment depends on, which is a distinct job done with distinct tools. If we spot a problem at the air handler during the clean, we’ll show you what we found instead of guessing.

Return and Supply Sides Together

Cleaning only the supply registers leaves the return side – where the dust actually enters the system – untouched. We treat both sides as one network because that’s how your air moves. It’s a longer job, and it’s the only way the result holds.

Vent Cleaning

Vent Cleaning focuses on the registers, grilles and branch openings where dust and debris first become visible in a St. Louis home, and it’s the service most homeowners picture when they call. It makes sense when you can see buildup on the grille faces, when a single room’s vent blows noticeably dustier air than the rest, or when pets and foot traffic have pushed debris toward the openings. We pull the grilles, clean them, and run extraction back through the branch lines so the vent face and the duct behind it are both handled. Vent cleaning in St. Louis generally runs $150-$300 as a standalone job, and it can be folded into a full-system clean. The written estimate sets the final price.

Grilles and Register Faces

A grille that’s been in place for years holds dust on both sides, and the back is the side nobody sees. We remove, clean and reinstall each grille as part of the visit. It makes a visible difference in a single afternoon.

The Branch Lines Behind Them

Cleaning the vent face without the branch line behind it only solves the cosmetic half of the problem. The extraction whip goes back through each branch to the main trunk. That’s where the settled debris actually lives.

Ductwork Cleaning

Ductwork Cleaning goes after the structure itself – the trunk lines, the flexible and rigid branch runs, the joints, and the seams where dust collects out of the airstream. It matters most in older St. Louis housing stock, where duct systems have been added to, patched and rerouted over time, and where a forty-year-old run may have never been touched. It’s also the right service when you’ve noticed air leaking at a seam or a run that seems to dead-end. We work the full network with Rotobrush and Nikro equipment under negative pressure, and because we also do air duct repair, anything we find that’s compromised we can fix. Ductwork cleaning in St. Louis typically runs $350-$700 for a standard system. The written estimate you receive sets the final price.

Joints, Seams and Connections

Every joint is a place where dust collects and where air can escape. We clean the seams rather than skipping past them. Connections that have come loose are noted and, where repair is needed, handled on the same visit.

Flexible and Rigid Runs

Flex duct needs a different touch than rigid metal – too aggressive and you damage the liner. Our technicians adjust the approach run by run. That’s part of why the equipment matters as much as the technique.

Air Duct Inspection

Air Duct Inspection is a look inside the system before anyone commits to a cleaning or a repair, and it’s the step that tells you what you’re actually dealing with. You need it when you’ve had a pest problem, when a renovation has filled the house with dust, when someone in the home has developed a new sensitivity to the air, or when an HVAC tech has flagged the ductwork. We check the main trunk, the branch runs, the air handler cabinet and the registers, and we use professional-grade tools to see inside runs that a flashlight can’t reach. Air duct inspection in St. Louis usually runs $75-$200, and if you go ahead with cleaning the inspection findings shape the plan. The written estimate sets the final price.

What We Look For

We check for debris depth, disconnected or crushed runs, torn flex liner, moisture staining, and pest evidence. Each condition points to a different next step. Knowing which one you have is the whole point of the inspection.

Findings in Plain Language

We tell you what we found and what it means, without a sales script. If the ducts are in better shape than expected, we’ll say so. If a repair makes sense, that’s a separate conversation with its own estimate.

Residential Air Duct Cleaning

Residential Air Duct Cleaning is built around the way a family actually lives in a house: pets, kids, cooking, seasonal allergies, and a system that runs through St. Louis summers and winters alike. It’s the right service after a move-in, after a renovation, when a new baby is on the way, or when the house has simply gone many years without the ducts being touched. We work quietly and cleanly, seal the work area, and use HEPA containment so the process doesn’t invade the rest of the home. Residential air duct cleaning in St. Louis typically runs $350-$700 depending on square footage and the number of runs. Larger homes with multiple systems run higher. The written estimate sets the final price.

Allergies and Air Quality

If someone in the household reacts to dust more than they used to, the ductwork is a reasonable place to check. We pair our cleaning with equipment from Honeywell and Aprilaire, so we understand whole-home air quality, not just the ducts. If a filtration upgrade makes sense, we can discuss it as a separate question.

Working Around Your Household

We keep the work area contained and set up drop cloths before we start. The house stays livable while we work. When we finish, we walk through what we did and show you the before-and-after photos.

Commercial Air Duct Cleaning

Commercial Air Duct Cleaning handles the larger systems in offices, retail spaces, restaurants and multi-unit properties, where ductwork runs longer, carries more traffic and often serves people who didn’t choose the building. It makes sense on a scheduled basis, before an inspection, after a tenant build-out, or when occupants start complaining about dust or air quality. We bring the same Rotobrush and Nikro extraction systems and Abatement Technologies containment to commercial work, scaled to the size of the system. Commercial air duct cleaning in St. Louis typically runs $600-$1,500 depending on square footage and system complexity. The written estimate sets the final price.

Scheduling Around Business Hours

Commercial work has to happen around the way the building operates, not the other way around. We plan the schedule with the property manager in advance and stage equipment to keep disruption to a minimum. If the work has to happen in phases, we say so up front.

Documentation for Property Managers

Property managers need to show the work was done, not just hear that it was. We document what we cleaned and provide before-and-after photos of the system. That record is useful for tenants, owners and future maintenance planning.

Brands We Service

We work with Honeywell and Aprilaire equipment regularly, and we understand how their components interact with the ductwork – where filtration and humidification tie in, and where a filter change alone won’t fix a bigger problem. We’re equipped to recommend and service systems built around those names.

Our extraction equipment comes from Rotobrush, Nikro and Abatement Technologies, and our approach is tuned to that hardware. Whether you have Honeywell or any other make, we can help – the ductwork underneath the system is the same physics either way.

Signs You Need a Pro Right Now

• Visible dust trails at the vents. If you can trace a dark streak from a register across the ceiling or wall, dust is being pushed out rather than carried back through the filter. It usually means the buildup inside has reached the point where airflow is disturbing it.
• Musty or stale smell when the system kicks on. A smell that appears only when the blower runs points to the ductwork, not the room. It’s worth checking before it becomes a bigger problem.
• Recent renovation or move-in. Drywall dust, sawdust and construction debris settle into every run, and a new home’s duct history is unknown. Cleaning after the work is done protects the next several years of air.
• Allergy symptoms that get worse indoors. If the house makes symptoms worse than the outside air does, the ducts deserve a look. An inspection will tell you whether the source is in the system or somewhere else.
• Uneven airflow room to room. One weak register can mean a disconnected or crushed run, not just a dirty duct. That’s a repair question as much as a cleaning one, and we handle both.

Our Process, Step by Step

1. 1
   Free estimate and walk-through. We look at the system, count the runs, and ask about the history of the home. You get a written estimate with one flat price per system – no per-vent pricing, no surprises.
2. 2
   Containment setup. We seal registers and openings and hook up Abatement Technologies HEPA containment before any cleaning starts. Nothing we loosen escapes into the room.
3. 3
   Full-system extraction. Rotobrush and Nikro systems run the length of every branch and trunk line, scrubbing the walls and pulling debris into the vacuum stream. We work the supply and return sides together.
4. 4
   Air handler and register detail. We clean the air handler cabinet and remove, clean and reinstall each register grille. Detail work is what separates a thorough clean from a quick pass.
5. 5
   Before-and-after review. We walk the home with you, show before-and-after photos of your own ducts, and note anything that needs a repair. If repair is needed, we can schedule it – same visit where possible.
