Whole-system duct and dryer vent check with before-and-after photos - you see exactly what came out of your vents
That "$99 whole-house special" is a bait ad - the real number appears once they are in your hallway, or the "clean" is a shop-vac at the register. We photograph the inside of your ducts before and after instead.
Fast, Reliable Air Duct Cleaning Across Richwood
Most homes in Richwood, TX need complete air duct cleaning every three to five years, with costs typically running $350-$650 for a full residential system. Homes near Highway 332 or with post-Harvey moisture history often require camera inspection first to determine whether cleaning will suffice or replacement is the smarter call. We’re Kestrel Air Duct Cleaning, and our crews serve Richwood from our Dallas-Fort Worth dispatch office with background-checked, uniformed technicians who arrive in the window we promised. Call (469) 972-3151 for a free written estimate before any work begins.
Richwood sits in Brazoria County, just inland from the Gulf, and that location shapes everything about your ductwork. The humidity stays brutal most of the year. Industrial particulates drift in from the Freeport petrochemical corridor. And too many homes still carry moisture damage from 2017 that never got properly dried. We know the difference between a duct system that can be cleaned and one that’s past saving, and we document it so your insurer understands too. That’s why Richwood homeowners call us when they want the job done once, done right, and done with a price in writing before a single vent is touched.
Why Kestrel Air Duct Cleaning Is Richwood’s Preferred Air Duct Cleaning Company
We’ve built our reputation in Richwood on showing up when we said we would and leaving the price where we left it. No doorstep revisions. No “we found something else” invoices. The Kingswell Guarantee, which governs every Kestrel job since our founding in 2004, requires four things: a written price before work begins, a defined arrival window, a clean job site, and a written guarantee with a free return visit if the work fails within the guarantee period. Dale Whitmore stands behind that standard on every Richwood call we take.
Our technicians know Brazoria County housing stock. They’ve pulled failed flex duct from 1980s ranch homes off Highway 332. They’ve documented mold colonization in air handler closets that flooded during Harvey and never dried properly. They understand that a home near the petrochemical plants presents a completely different contamination profile than one farther inland. That local knowledge means we don’t waste your time with cleaning when replacement is the honest recommendation, and we don’t push replacement when a thorough Rotobrush and negative-air extraction will solve it.
Calls to (469) 972-3151 are answered by a live person, 24/7. Not a queue. Not a robot. A real conversation, any time of day, to get your Richwood appointment scheduled with a real arrival window.
Air Duct Cleaning Services in Richwood
Air Duct Cleaning Services in Richwood address a dual contamination problem that most Texas cities simply don’t face. Our negative-air extraction process, using Nikro portable HEPA vacuums, pulls loosened debris out of your duct system while Rotobrush rotary brush agitation dislodges buildup from the duct walls. In Richwood, that buildup often includes not just ordinary household dust and pollen but also the greasy, fine-particulate residue that settles in supply ducts from the Freeport industrial corridor, plus mold colonies fed by 85%+ relative humidity that persists most of the year. A typical residential full-system cleaning in Richwood runs $350-$550, with larger homes or systems requiring video inspection first ranging up to $650.
Supply and Return Duct Cleaning
Supply ducts push conditioned air into your rooms; return ducts pull it back to the air handler. Both sides need attention, but in Richwood they need different approaches. Supply runs near Highway 332 often carry that bonded greasy film that traps allergens, while return trunks in post-Harvey homes may harbor mold that only a camera inspection reveals. We clean both, but we check both first.

Video Inspection Before Cleaning
We feed a lighted camera through your ductwork before deciding on the scope of work. In Richwood, this step is non-negotiable for homes built before 1995 or any home with known moisture history. The camera shows us whether we’re looking at cleanable surface buildup or failed duct liner that agitation will only destroy further. You see the footage. We explain what it means. Then we agree on a written price.

HVAC Duct Cleaning in Richwood
HVAC Duct Cleaning in Richwood requires understanding how your entire heating and cooling system interacts with coastal subtropical conditions. The air handler, plenums, and trunk lines are all part of the same airflow loop, and contamination anywhere circulates everywhere. Our process includes the full loop: Rotobrush contact cleaning of accessible duct runs, Nikro negative-air extraction at 2,000+ CFM to capture loosened debris, and Abatement Technologies HEPA filtration to prevent recontamination of your living space during the job. Commercial systems in Richwood’s light industrial areas typically run $800-$1,400 depending on unit count and access complexity.
Mold and Moisture Assessment
Richwood’s dew points above 75°F for much of summer mean mold can colonize duct interiors within weeks of any moisture intrusion. We measure moisture content in duct boards and flex duct with calibrated meters. Readings above 16% indicate active problems that cleaning alone won’t fix. We tell you exactly where we measured and what the numbers mean for your decision.
Post-Flood Duct Evaluation
Hurricane Harvey flooded large portions of Brazoria County, and many Richwood attics and air handler closets still carry trapped moisture from that event. Our camera inspection looks for mold growth on duct liner that standard surface cleaning cannot reach. When we find it, we document with photos and moisture readings so you have evidence for your insurer. Sometimes cleaning works. Sometimes replacement is the only honest call. We don’t guess, and we don’t profit from selling you work you don’t need.
Trusted Brands We Service in Richwood
Our technicians arrive with professional-grade equipment, not shop vacs from a big-box store. Rotobrush rotary brush systems physically contact and dislodge debris from duct walls. Nikro negative-pressure units create the suction that pulls those contaminants out of your home entirely. Abatement Technologies HEPA filtration captures particles as small as 0.3 microns, keeping what we loosen out of your living space while we work. For homeowners who want to maintain cleaner air between service visits, we also offer Honeywell, Aprilaire, and Guardsman filtration products with recommendations specific to Richwood’s high-humidity, high-particulate environment. We stock filters and basic IAQ components locally so Richwood customers aren’t waiting on shipped parts.
Common Air Duct Cleaning Problems We See in Richwood Homes
- Post-Harvey mold in air handler closets. Moisture trapped since 2017 has colonized duct liner with mold that surface cleaning won’t touch. Only camera inspection and source removal reveal the full extent, and many homeowners in the Brazoria County flood zone still haven’t addressed it.
- Petrochemical particulate bonding near Highway 332. The greasy, fine-particulate residue that drifts from the Freeport industrial complex bonds to fiberglass duct board and flex duct interiors. Agitation tools alone smear it deeper instead of removing it, requiring specialized solvent pre-treatment and extended negative-air extraction.
- Aging duct board hardening and fiber shedding. Richwood’s 1970s-1990s housing stock features original fiberglass duct board that deteriorates under persistent moisture. Homeowners mistake the resulting fiber shedding for ordinary dust, but it’s actually liner breakdown that requires replacement.
- Flex duct collapse in attic spaces. Original flex duct from the petrochemical boom years has sagged, torn, or collapsed in hot Richwood attics, creating airflow restrictions that strain HVAC equipment and spike energy bills before homeowners realize the ducts are the problem.
Pricing for Air Duct Cleaning in Richwood, TX
Most Richwood homes fall between $350 and $550 for a complete residential air duct cleaning, with larger systems or those requiring video inspection first ranging up to $650. Commercial duct cleaning in Richwood typically runs $800-$1,400 depending on the number of air handlers and access difficulty. What moves you within those ranges? System size matters, obviously. So does contamination type: standard dust and pollen cleaning sits at the lower end, while petrochemical residue removal or post-flood mold remediation requires more time and specialized treatment. Homes with original 1970s-1990s flex duct or duct board may need section replacement rather than cleaning, and we price that separately with full transparency.
We give you one flat price per system, agreed in writing, before any work begins. No per-vent pricing that balloons at the door. No “we found an extra return” surprises. The written price is in your hands before a single vent is touched. That’s the Kingswell Guarantee, and it’s how we’ve operated since 2004. Call (469) 972-3151 for your free estimate.

FAQs About Air Duct Cleaning in Richwood
It depends on moisture damage extent and mold colonization depth, which we determine with camera inspection and moisture meter readings. Ducts with surface mold on metal trunk lines can often be cleaned successfully; ducts with mold penetrating fiberglass liner or flex duct with moisture readings above 16% typically need replacement. We document everything with photos and readings so your insurer can see the evidence. Call (469) 972-3151 to schedule an evaluation.
Proximity to the Freeport petrochemical complex, including major Dow Chemical operations, means fine industrial particulates drift into residential HVAC intakes and bond with humidity inside ductwork. That greasy residue traps allergens and odors in ways ordinary household dust doesn’t, and it requires specialized pre-treatment before rotary brush agitation and negative-air extraction can remove it effectively. Homes farther from the corridor, toward the center of Richwood, typically show standard dust and pollen buildup instead.
Richwood homeowners should generally use MERV 8-11 filters and change them every 60-90 days, not the 6-month intervals that work in drier climates. Higher MERV ratings trap more particles but can restrict airflow in systems already strained by humidity, and they clog faster here. We assess your specific system during each visit and recommend Honeywell, Aprilaire, or Guardsman options matched to your equipment and Richwood’s conditions.
Insurers accept well-documented claims with clear evidence of storm-related damage. We provide dated photos, moisture meter readings, video inspection footage, and written technician notes specifying which damage is storm-related versus ordinary wear. The field vignette we encountered: a ranch home off Highway 332 where our documentation of greasy petrochemical residue bonded with failed flex duct liner led to first-submission claim approval. Proper documentation makes the difference. Call (469) 972-3151 and we’ll explain exactly what we document and how.
Every three to five years for standard maintenance, but every two to three years for homes near Highway 332 or with any history of moisture intrusion. The 85%+ relative humidity that persists most of the year accelerates mold colonization, and post-Harvey moisture history increases risk significantly. We don’t push unnecessary service; we’ll inspect your system and tell you honestly whether it’s time.
