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.

AfterTrusted Air Duct Cleaning for Katy Homeowners
Air duct cleaning in Katy typically costs $350-$850 for a complete residential system and is scheduled within 2-4 business days. CleanRun Air Duct Cleaning Katy has served this market since 2013 with written prices delivered before any work starts, every time, under Haven Standard Clause 1. Call (346) 666-7165 for a free estimate with no obligation.
Katy homeowners who bought between 2015 and 2025 are finding something the home inspection didn’t catch: construction debris, pollen compaction, and in newer subdivisions like Cinco Ranch, residual drywall dust that continues to circulate through the HVAC system for years. We’ve documented this in 52,000+ homes. The camera doesn’t exaggerate. It shows a 2-inch debris ridge at the plenum (the central distribution box where all duct runs connect), or it shows a clean run. The photo record we deliver with every job makes that distinction visible.
Our crews work under the H.A.V.E.N. Standard, with background-checked, uniformed technicians identified by name before arrival. Every job concludes with a Documented Photo Record of every duct run, before and after, and is backed by the 365-Day Done Right Promise in writing. This is not a policy subject to manager approval. It is a written guarantee.
What Our Air Duct Cleaning Service Includes
Residential Duct Cleaning
Residential Duct Cleaning covers the complete network of supply and return runs, registers, and the main trunk lines in single-family homes, townhomes, and condos throughout Katy, Cinco Ranch, and surrounding areas. Most Katy homes built after 2015 have flexible ductwork (insulated, wire-reinforced tubing) that requires lower suction pressure than rigid metal to avoid collapse or seam separation. Our crews adjust negative-pressure extraction (vacuum force applied to the entire system while sealed) based on duct material, which we verify during the initial video inspection. CleanRun has cleaned residential systems in Katy neighborhoods from Old Town to Grand Lakes to Firethorne, and every job starts with a written price before a single panel comes off.
Commercial Duct Cleaning
Commercial Duct Cleaning addresses the larger-capacity systems found in Katy office parks, retail spaces, medical offices, and multi-tenant buildings along I-10 and the Grand Parkway corridor. These systems use thicker-gauge metal ductwork, often with internal insulation liners that trap debris differently than residential flex duct. We coordinate with building maintenance staff to minimize disruption, scheduling work during off-hours when needed. Our equipment roster includes Nikro and Abatement Technologies commercial-grade negative-pressure machines designed for higher CFM (cubic feet per minute) capacity. Every commercial job receives the same written price guarantee and Documented Photo Record as our residential work.
Supply Duct Cleaning
Supply duct cleaning targets the runs that deliver conditioned air from your HVAC unit to each room’s registers. In Katy, where summer cooling loads run 8-9 months annually, supply ducts accumulate the most visible debris: pollen, pet dander, and fine dust that bypasses standard filters. We seal each supply register during cleaning to maintain negative pressure throughout the run, then agitate debris with mechanical brushes before extraction. The Rotobrush system we deploy uses a rotating brush head with simultaneous vacuum draw, which we select based on duct diameter and debris type observed during the video inspection. You’ll see the before-and-after photos for every supply run in your delivered job record.
Return Duct Cleaning
Return Duct Cleaning addresses the larger, often overlooked runs that pull air back to the HVAC unit for reconditioning. These ducts are typically wider than supply lines and collect bulk debris near the filter housing and at turns where airflow slows. In Katy’s newer subdivisions, we’ve documented construction debris in return trunks that remained from original build-out, including drywall fragments and insulation scraps. Because return ducts are under negative pressure during normal system operation, leaks here draw attic air and its contaminants directly into your breathing air. Our cleaning includes visual inspection of seams and connections, with repair recommendations documented in writing if we find separation.
Full System Cleaning
Full System Cleaning encompasses supply ducts, return ducts, the plenum, registers, grilles, and the HVAC cabinet interior, including the blower assembly and evaporator coil housing when accessible. This is what most Katy homeowners need when they haven’t had professional duct cleaning in 5+ years, or when they’re addressing persistent dust issues, allergy symptoms, or musty odors that filter changes haven’t resolved. We price full system cleaning as one flat rate per system, not per vent, so you know the total before we begin. The scope is defined in writing, and the Documented Photo Record covers every component we access. Haven Standard Clause 1 applies: the written price is the price.
Video Inspection
Video inspection uses a flexible borescope camera threaded through the ductwork to record internal conditions before any cleaning decision is made. We offer this as a standalone service for Katy homeowners who want documentation of duct condition, perhaps for a home sale, warranty claim, or dispute with a builder. The footage is timestamped and delivered as part of your job record. Many of our customers in Brookshire and Pecan Grove request video inspection first, then schedule cleaning based on what the camera reveals. There is no pressure to proceed; the inspection fee is credited toward cleaning if you book within 30 days.

Brands We Service for Air Duct Cleaning
CleanRun technicians are trained on duct systems paired with all major HVAC brands common in Katy installations. We’ve serviced hundreds of Honeywell integrated air cleaner systems, including their electronic air cleaners and media filters that mount directly to the return plenum. These units require specific handling during duct cleaning to avoid damaging the cells or media cartridges, and we stock replacement media for common Honeywell models so you don’t wait for a parts order.
We also regularly encounter Rotobrush equipment on jobs where prior cleaning was attempted, and we maintain Guardsman-certified protocols for homes with their air filtration add-ons. Whether you have a Honeywell electronic air cleaner, a Guardsman filtration system, Rotobrush legacy equipment, or any other make, we can clean the connected ductwork without voiding manufacturer warranties or damaging integrated components. Our crews carry the technical manuals for systems installed in Katy since 2013.
BeforeAfterSigns You Need Air Duct Cleaning Right Now
- Visible dust blowing from registers when the system starts. This indicates debris accumulation in the supply ducts that has exceeded the system’s ability to contain it. In Katy, where caliche dust and Gulf Coast pollen are constant, this typically appears 3-5 years after the last cleaning. The dust you see represents a fraction of what’s adhered to duct walls.
- Uneven airflow between rooms, with some registers barely blowing. This often signals a partial blockage in the duct run, frequently at an elbow or where flexible duct has sagged or been crushed. We’ve found complete obstructions from construction debris in Katy homes built 2015-2020, including dropped tools and insulation blocks that were never removed.
- Persistent musty or sour odors when the HVAC runs. Odors indicate microbial growth on debris deposits, typically in the return duct or evaporator coil housing where moisture accumulates during Katy’s humid months. Cleaning removes the organic material that supports growth; sanitizing addresses what remains on surfaces.
- Increased allergy symptoms or respiratory irritation indoors. When duct debris includes pollen, pet dander, and dust mite fragments, the HVAC system recirculates these irritants continuously. Katy residents who moved here from drier climates often notice this first, as the local pollen load is significantly higher and the cooling season extends exposure.
- Recent renovation or construction work in the home. Even with protective measures, drywall dust, sawdust, and insulation particles enter ductwork during remodeling. We recommend inspection within 30 days of project completion, particularly if registers were active during work. The fine particulate from modern materials is especially adhesive and resists standard filter capture.
Our Air Duct Cleaning Process - Step by Step
- 1
Written price delivered before work begins. We inspect your system, define the scope in writing, and provide a flat price per system. Haven Standard Clause 1: no work starts until you have the total in writing. This applies to every job in Katy, from a single condo unit to a multi-system home in New Territory.
- 2
Video inspection of accessible duct runs. Our technician threads a borescope camera through representative supply and return lines to record pre-cleaning conditions. You’ll see the footage. We note specific problem areas: debris depth, moisture staining, seam separation, or pest evidence. This becomes the baseline for your before-and-after comparison.
- 3
System sealing and negative-pressure setup. We seal all registers and the HVAC cabinet, then connect a high-capacity negative-pressure extraction machine to the plenum. This creates vacuum force throughout the entire duct network, preventing debris release into your home during cleaning. Our Nikro and Abatement Technologies equipment is sized to the system CFM rating.
- 4
Mechanical agitation and debris extraction. Technicians access each duct run through the registers, using rotating brushes, compressed air whips, or hand tools selected based on duct material and debris type. The Rotobrush system deploys for flexible duct with moderate buildup; rigid metal lines may receive more aggressive agitation. All loosened debris is drawn into the vacuum containment.
- 5
Post-cleaning verification and photo documentation. The borescope camera re-enters each cleaned run to capture after-condition footage. These images, with timestamps, are compiled into your Documented Photo Record and delivered as a standard job deliverable. We review findings with you before final payment. The 365-Day Done Right Promise is activated in writing.
How Much Does Air Duct Cleaning Cost in Katy?
A typical residential full system cleaning in Katy runs $450-$850 for a single HVAC system, depending on home size, duct accessibility, and debris volume. A condo or small townhome with straightforward access might fall at the lower end; a 4,000+ square-foot home in Cinco Ranch with multiple systems, attic ductwork, and significant construction debris accumulation could reach the upper range. We price per system, not per vent, so the written quote you receive is the complete cost.
Commercial duct cleaning in Katy office and retail spaces typically starts at $1,200 and scales with system complexity, square footage, and scheduling constraints. We provide written quotes for commercial work with the same Haven Standard Clause 1 guarantee: the price is set before work begins.
Several factors affect where your job falls in these ranges. Duct accessibility matters: attic runs in Katy’s older homes (pre-2000) often require additional setup time. The number of HVAC systems increases cost linearly, though multi-system homes may qualify for consolidated pricing. Debris type affects labor: light dust extracts faster than compacted construction residue or moisture-compacted material. We assess these factors during our initial inspection and reflect them in the written scope.
To avoid overpaying, reject any quote that won’t commit to a total in writing, uses per-vent pricing, or advertises a teaser rate that “covers basic cleaning” with upsells required for actual results. These are the $79 coupon tactics that define the industry CleanRun was built to oppose. Our Free Second Opinion on Any Written Estimate lets you bring a competitor’s quote; we’ll put our number next to it, with scope defined in equal detail.
Every estimate is free and includes the video inspection footage. There is no charge to understand what your system needs.

Frequently Asked Questions - Air Duct Cleaning in Katy
Air duct cleaning is the mechanical removal of accumulated debris from the interior surfaces of your HVAC ductwork, including supply runs, return runs, the plenum, and registers. It removes dust, pollen, pet dander, construction debris, and in some cases microbial growth, using negative-pressure extraction and mechanical agitation. The goal is restored airflow capacity and reduced recirculation of particulate matter, not “sterilization” of the system. Call (346) 666-7165 for a free estimate with video inspection.
A typical single-system residential job in Katy takes 3-5 hours from arrival to final walkthrough, depending on home size, duct accessibility, and debris volume. Larger homes with multiple systems, or properties with attic ductwork requiring additional setup, may extend to a full day. We schedule with adequate time reserved; your crew is not racing to another appointment. Call (346) 666-7165 to discuss your property’s specific requirements.
Professional full-system duct cleaning in Katy runs $450-$850 for residential properties, with commercial work starting around $1,200. Quotes significantly below this range typically employ bait-and-switch tactics: a low entry price for minimal work, followed by aggressive upselling for “deep cleaning,” additional vents, or sanitizing that should be standard. CleanRun delivers one flat price per system in writing before work starts, with no per-vent charges. Call (346) 666-7165 for an exact quote - estimates are free.
