Why Florissant Homeowners Call Bellmont Air Duct Cleaning for Air Duct Cleaning
Florissant is full of homes built by tract builders between the 1950s and 1970s, and most of them were laid out for heat only. When central air was added decades later, those same supply runs started carrying cold, damp air through the cooling season. Cleaning them means understanding what the system was designed for, not just running a vacuum through a register.
That’s the reason people in Florissant call us. We’re an indoor-air specialist, not a general handyman outfit that adds duct cleaning to a long menu. Our three services are air duct cleaning, dryer vent cleaning and duct repair – nothing else. We work with professional-grade Rotobrush and Nikro extraction systems and use Abatement Technologies equipment for proper containment, so the dust we pull out of your ducts leaves the house instead of settling into it.
We treat Florissant as its own market, because the homes here have their own patterns. If you live near St. Ferdinand Park or off Lindbergh Boulevard, your house is probably part of that mid-century build-out, and the duct issues we find are consistent: separated trunk joints, crushed branch runs, one undersized return doing the work of three. Call us and we’ll tell you what a typical job involves before anyone comes out.

Commercial Air Duct Cleaning in Florissant
Commercial Air Duct Cleaning in Florissant covers the small professional buildings, churches, medical offices and multi-unit properties that line the corridors near Highway 67 and Lindbergh Boulevard. The work is heavier than residential: larger air handlers, longer runs, and more demand on containment so that business can keep operating while we clean. A typical small commercial system runs roughly $900 to $2,800, set by the written estimate after we see the layout.
System Size and Zoning
Most commercial spaces in Florissant work off zoned systems with multiple returns, and a thorough clean means addressing each zone on its own. We video inspect before we extract, so nothing gets missed in the ceiling plenums.
Containment and Downtime
Negative pressure and HEPA filtration from our Abatement Technologies equipment keep the work contained, and we plan the schedule around your operating hours. You get before-and-after photos of the interior runs.
Air Duct Cleaning Services in Florissant
Air Duct Cleaning Services in Florissant usually start with a full system assessment, because the ducts here are rarely straightforward. We cover residential and commercial work, clean supply and return sides as one system, and include video inspection so you can see what we see. A typical whole-home clean runs $350 to $700 for a Florissant ranch, and if we find compromised runs during the job, repair is priced separately in the written estimate.
Supply and Return Ducts
Both sides get cleaned in one pass. A single-return ranch pushes a lot of lint and dust into the return trunk, and skipping it just moves the problem downstream.
Video Inspection and Repair
We run a camera through the trunk and main branches so you know the condition of what’s inside your walls. If we find a disconnected or crushed run, our technicians can usually correct it the same visit, since duct repair is one of our core services.

Trusted Brands We Service in Florissant
We work with Honeywell and Aprilaire air-quality systems and are familiar with how they interact with older ductwork, including filtration and humidification components common in Florissant homes that have upgraded over the years. If your system uses Honeywell controls or an Aprilaire filter cabinet, our technicians know how to clean around them without disturbing the setup. We don’t stock parts or handle installation – our scope is cleaning and duct repair – so when a component needs replacing, we’ll tell you plainly rather than guess. You get the right referral and a clean system, not a sales pitch.

AfterCommon Air Duct Cleaning Problems We See in Florissant Homes
- Separated trunk joints. Original sheet-metal trunks in these homes separate over decades, bleeding conditioned air into wall cavities. Cleaning alone won’t fix it – sealing does.
- Damp retrofitted runs. Central AC pushing cold air through furnace-era ducts keeps moisture in the runs through the long Missouri cooling season, feeding dust-mite and microbial buildup.
- Under-returned back bedrooms. One central return leaves far rooms with weak pull, so dust and lint settle in branch runs a quick register vacuum never reaches.
- Crushed or disconnected runs. Renovations and later remodels often leave ductwork pinched behind drywall. Video inspection shows the problem, and repair puts airflow back.
Pricing for Air Duct Cleaning in Florissant, MO
A typical residential air duct cleaning in Florissant runs $350 to $700 for a standard ranch or split-level. Full system cleaning including both supply and return sides tends to sit toward the upper end of that range, and larger homes with multiple returns can land higher. Commercial work starts around $900 and goes up with square footage and zoning. Duct repair is priced separately once we video inspect and find the specific runs that need sealing or reconnecting – most repairs fall between $200 and $600 depending on access. The written estimate sets the final price, and it’s free to get one. Call (877) 349-6189 and we’ll talk through your system before we quote.

FAQs About Air Duct Cleaning in Florissant
Because the original sheet-metal trunk joints in these 1950s-1970s homes have separated over decades, and cleaning removes the dust but doesn’t close the gaps. Sealing the leaks is usually the real fix, restoring airflow to back bedrooms that were starving. We quote sealing as a separate line on the written estimate. Call (877) 349-6189 for a free assessment – estimates are free.
It’s the long cooling season keeping damp air in furnace-era ducts that were never sized for cold, moist air. That moisture feeds dust-mite and microbial buildup in the runs, and the first hot week of June is when you notice it. Cleaning removes the buildup, and sealing the joints keeps it from returning as fast. Call us for an inspection – the estimate costs nothing.
Weak airflow to a back bedroom, a room that never quite cools, or a temperature gap from the front to the back of the house are the usual signs. Video inspection confirms it, and we run a camera through the trunk and main branches as part of the job. Repair follows when we find a break. Call (877) 349-6189 to schedule an inspection.
Yes. Newer construction has sealed, right-sized ductwork; the mid-century tract ranches here have original sheet metal with separated joints, single central returns and retrofitted AC. That calls for negative pressure, source removal and attention to sealing, not just a surface vacuum. Our technicians have up to 9 years of experience with exactly this kind of system. Call for a free quote.
Start with a moderate MERV rating rather than the highest filter that fits, because these systems were built with limited static pressure and a dense filter can choke airflow. A Honeywell or Aprilaire filter that matches your cabinet works well, and we’ll recommend a rating after seeing your setup. Call (877) 349-6189 for an estimate and a filter recommendation.
If your Florissant home is running on ductwork older than your central air, we can tell you what’s inside it and what it’ll take to put it right. Cleaning, sealing and repair all come from one specialist, with professional-grade equipment and a written price agreed before work starts. Call (877) 349-6189 for a free estimate. We answer 24/7, with fast dispatch from 7am to 7pm, Sunday through Friday.
