Air Duct Cleaning Company in Florissant, MO
Air duct repair in Florissant usually comes down to one thing: the ductwork was sized for a furnace and has spent the last several decades carrying air it was never built to move. Central air was retrofitted into most of these homes long after the walls went up, so undersized runs now push cooled, damp air instead of just warm air. Bellmont works through Bellmont Air Duct Cleaning as an indoor-air specialist, not a generalist who adds ducts to a long menu. We bring professional-grade Rotobrush and Nikro extraction and Abatement Technologies containment for the cleaning side, and we fix what we find rather than hand you a second contractor’s number. Call (877) 349-6189 to talk through the problem.
Why Florissant Homes Are Different
Florissant is a post-war inner-ring St. Louis County suburb, and the housing stock tells you almost everything about the ductwork inside. The brick-and-frame ranches and small split-levels that fill 63031, 63033 and 63034 went up from the 1950s into the 1970s under tract builders and small local builders, and most still carry their original rigid sheet-metal trunk lines. A single central return was standard. The number of homes built with furnace-only ductwork and then fitted with central air decades later is high, and those runs were never widened to suit the new load.
The climate does the rest. Hot, muggy Missouri summers and cold winters mean the system runs hard in both seasons, and the long cooling season leaves evaporator coils and the ducts downstream of them damp for months. In old ductwork, that moisture is what feeds dust-mite and microbial buildup. Most of the owners we meet in Florissant have lived in the same house for 20 to 40 years, so this is legacy-system work: restoring airflow and air quality in aging suburban homes, not mold remediation and not new-build tuning.

Our Main Florissant Services
Two calls come up more than any other here: cleaning that has been put off for too long, and a dryer that takes two cycles to finish a load.
Air Duct Cleaning in Florissant
In Florissant, duct cleaning is mostly about volume. Decades of accumulated dust sit in original sheet-metal trunks, and the later add-on air conditioning keeps the downstream runs damp through the long cooling season. We work with negative-pressure extraction using Rotobrush and Nikro systems, and we contain the work area so the dust leaves the house instead of settling on your furniture. Weak airflow to a back bedroom usually shows up during cleaning as a blocked or crushed run, and we note it while we have access. For the full scope, see air duct cleaning in Florissant.
Dryer Vent Cleaning in Florissant
Older Florissant homes often have the dryer pushed against an under-sized or kinked vent run, and decades of lint build up where the line bends. That matters beyond a slow cycle: dryer vent lint is a leading cause of residential house fires, and the long runs common in mid-century ranch layouts give it more places to collect. We clear the full length of the vent, not just the first few feet behind the appliance. For the details, see dryer vent cleaning in Florissant.
Air Duct Repair in Florissant
Air duct repair in Florissant is one of the few services where the local housing era does most of the diagnosis. Homes here were largely fitted with furnace-only ductwork, then had central air retrofitted much later, so the same undersized run now carries cooled, damp air. That mismatch is behind most of the weak airflow to back bedrooms and the musty smell on the first hot week of June. Our technicians have up to 9 years of experience and handle the full scope of air duct repair, so parts that fail during a cleaning get addressed in the same visit.
Ductwork Repair
Signs you need it
Uneven temperatures room to room, whistling at a register, a run that’s visibly crushed or separated in the basement, or a dusty smell that returns soon after a filter change all point to a breach somewhere in the trunk or branch lines.
What it costs in Florissant
Typical ductwork repair in Florissant runs about $250 to $900, with small joint and seal repairs at the low end and multiple failed sections closer to the top of that band.
How we do it
We trace the run with the system running, isolate the failure, then seal, re-support or replace the damaged section, tape with proper mastic, and re-test airflow at the affected registers before we leave.
Air Duct Replacement
Signs you need it
Original sheet-metal that is rusted through, full of debris that won’t extract, or so undersized that no amount of repair gets a back bedroom enough air is a replacement job, not a repair.
What it costs in Florissant
Air duct replacement in Florissant typically lands between $1,200 and $3,800 for a residential system, depending on how much of the trunk and how many branch runs are affected.
How we do it
We map the existing layout, remove and dispose of the failed sections, size and install new sealed duct, then verify static pressure and airflow room by room against what the equipment actually needs.
What Air Duct Repair Costs in Florissant
| Item | Typical range in Florissant |
|---|---|
| Ductwork repair (seal, re-support, small section) | $250 – $900 |
| Air duct replacement (residential system) | $1,200 – $3,800 |
| Full duct cleaning | $350 – $700 |
Can old ductwork in a Florissant ranch home be repaired, or does it have to be replaced?
Most original sheet-metal trunks in Florissant can be repaired. Sealing and re-supporting failed joints solves the majority of cases; replacement comes up when metal is rusted through or the run is too undersized to fix.
Why do back bedrooms in Florissant get so little airflow?
Because the runs were sized for heating only. When central air was retrofitted into these furnace-only homes, the long duct to a back bedroom was never widened, so it moves cooled air poorly. Duct repair can recover some of that; right-sizing the run fixes the rest.
Brands We Service in Florissant
We work with system components from Honeywell and Aprilaire, two of the best-known names in whole-home air quality, and we use Abatement Technologies equipment for proper HEPA containment while we clean. Parts for older Florissant systems can take a few days to source, and we’ll tell you up front when that’s the case. You can read about the full lineup on our brands page.

What Florissant Customers Say
"Did the dryer vent while they were here for a small add on price. The dryer now finishes a load in one cycle instead of two."
- Malik Bryant"Quoted per system rather than the bait and switch per vent pricing everybody else in town uses. The number I was told on the phone was the number on the invoice."
- Whitney Sutton"Fair price and thorough work. They ran about an hour and a half past the estimated finish time, so don't schedule anything tight after."
