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.

AfterHow Much Does Air Duct Cleaning Cost in Houston?
Air Duct Cleaning in Houston typically costs between $299 and $699 for a standard single-family home, with most jobs in neighborhoods like The Heights, Meyerland, and Katy-area subdivisions landing in the $350-$500 range. That price covers negative-pressure extraction through every supply and return run, plus a documented photo record of each duct before and after the work. Add-ons like mold treatment, dryer vent cleaning, or a UV air sanitizer will push the total higher – but at CleanRun, you’ll see every line item in writing before a single panel comes off the wall.
Air Duct Cleaning Cost Breakdown (2026)
Residential duct cleaning in Houston is priced on system size, duct count, and whatever the camera actually finds inside. The table below reflects real jobs CleanRun has completed across the Houston metro in 2025 and 2026 – not survey data, not national averages.
| Service | Typical Houston Price Range | Notes |
|---|---|---|
| Air duct cleaning – small home (under 1,500 sq ft, 1 system) | $299 – $379 | Common in Midtown townhomes, Montrose bungalows |
| Air duct cleaning – mid-size home (1,500-2,800 sq ft, 1 system) | $379 – $499 | Most common bracket – Memorial Villages, Friendswood, Sugar Land |
| Air duct cleaning – large home (2,800-4,500 sq ft, 2 systems) | $499 – $699 | Tanglewood, West University Place, Bellaire two-story |
| Air duct cleaning – estate / over 4,500 sq ft, 3+ systems | $699 – $1,100+ | River Oaks, Piney Point Village, custom builds |
| Dryer vent cleaning (add-on or standalone) | $99 – $179 | Houston’s humidity accelerates lint compaction |
| Antimicrobial / mold treatment (EPA-registered fogging) | $149 – $299 | Common recommendation after flood remediation or post-Harvey damage |
| UV air sanitizer installation (Honeywell, Aprilaire) | $249 – $449 installed | Priced by unit and system compatibility – written scope first |
| Duct repair / sealing (per linear foot) | $8 – $22 per linear foot | Flex duct delamination is common in attic-run systems here |
| Free second opinion on a competitor’s written estimate | $0 | Bring the quote – CleanRun puts its number next to it in writing |
A few things push jobs outside these ranges. Homes with significant microbial growth – which Houston’s combination of high humidity, aging flex duct, and intermittent power outages from storm damage can produce – often need antimicrobial treatment added to the base cleaning price. Duct systems in older Houston homes, particularly pre-1990 construction in areas like Garden Oaks or Oak Forest, sometimes have fiberglass-lined ductboard that requires a different extraction approach with Nikro equipment rather than a standard rotary brush pass. That changes the labor time and the price – and you’ll see exactly why on the written scope before anything starts.
What you will never see on a CleanRun invoice is a price that appeared after the crew arrived. Haven Standard Clause 1 means the written price is delivered before any work starts, every time, without exception. That is not a policy subject to manager approval. It’s how every one of our 52,000+ jobs has been priced since 2013.
What Affects Air Duct Cleaning Pricing in Houston
Six factors account for most of the price variation you’ll see across Houston quotes. Understanding them helps you compare estimates honestly – and spot when a low number is missing something real.
- Number of duct runs and return air pathways: A 2,200-square-foot home in Pearland with a single central return and 14 supply registers is a straightforward job. The same square footage in a custom-built Bellaire home with multiple returns, zoned dampers, and a complicated plenum (the central distribution box that feeds the individual duct runs) takes longer and costs more. Count your registers before you call – it’s the fastest way to anchor your estimate.
- Houston’s climate and what it does to ductwork: The Houston metro runs its HVAC systems harder and longer than most U.S. cities. A system that cycles 10-11 months a year accumulates debris faster than one running six months in a northern market. Attic-run flex duct – the standard in most Houston residential construction – also sits in 140-160 degree summer attic temperatures, which accelerates inner liner breakdown and debris shedding into the air stream. When the camera shows liner debris in the airflow, extraction takes longer.
- System access and attic configuration: Some of Houston’s older two-story homes, particularly in Tanglewood and Afton Oaks, have duct chases running inside walls with access only at registers. That’s not a reason to skip runs – it’s a reason to document photographically what can and cannot be accessed, and adjust the written scope accordingly before work starts.
- Contamination type and severity: Dust and debris removal is base pricing. Microbial growth – visible or camera-detected mold or mildew in the duct interior – requires an additional EPA-registered antimicrobial treatment after extraction. Houston’s humidity makes this more common here than in drier markets. Post-hurricane or post-flood ductwork, a reality for a significant number of Houston homes since 2017, often presents with both debris and contamination that require both steps.
- Equipment used on the job: There’s a real cost difference between a technician with a shop vacuum and a crew using commercial-grade Rotobrush rotary agitation equipment connected to a Nikro negative-pressure extraction unit. The Rotobrush scrubs the duct wall while the Nikro unit pulls the dislodged material toward the collection point rather than redistributing it. Abatement Technologies air scrubbers capture what escapes during the process. That equipment costs more to own and operate, and it costs more to put in front of your house. It’s also why the photo record looks different when the job is done.
- Add-on services bundled vs. priced separately: The $79 coupon you’ll see advertised in Houston typically covers a visual inspection and vacuum pass on a handful of registers – not a full system cleaning. When the upsell for actual cleaning comes during the visit (and it always comes), you’re negotiating without a written price in hand. CleanRun prices the full scope upfront: if you also need dryer vent cleaning or a Honeywell UV sanitizer installed, those appear as separate line items on the written estimate before the job starts – not as surprises mid-job.
BeforeAfterHouston’s $79 Coupon Problem – What That Price Actually Buys
If you’ve searched for Air Duct Cleaning Near Me in Houston, TX recently, you’ve seen them: “$79 whole-house duct cleaning,” sometimes “$49,” sometimes “free inspection.” Houston has one of the more active coupon-based duct cleaning markets in Texas, and it’s worth understanding the mechanics before you call any number on a flyer.
The $79 price typically covers a technician arriving with a portable vacuum and performing a visual inspection. It is, in most cases, a foot-in-the-door price. The documented playbook – reported repeatedly by Houston-area homeowners on community boards in neighborhoods from Cypress to Clear Lake – is an in-home upsell to a “full cleaning” priced at $400-$800, quoted verbally, with pressure to decide before the tech leaves. No written price is provided before the upsell conversation starts. No photos document what was actually found or what was actually cleaned.
CleanRun was built as the direct answer to that model. Every job starts with a written price. Every duct run is photographed before and after with equipment that goes into the duct – not a phone camera held at the register opening. The 365-Day Done Right Promise means if the documentation doesn’t show what was promised, we come back and do it. That commitment is in writing on every job, not stated only in marketing copy.

How to Save on Air Duct Cleaning in Houston
The honest version of this section isn’t a list of coupon codes. It’s a description of how to avoid paying twice – which is what happens when a cheap job redistributes debris rather than removing it, or when a technician skips runs and photographs only the ones they cleaned.
- Book during shoulder season (March-April or October-November): Houston’s HVAC service industry peaks in late May through August when systems are running hardest and homeowners notice problems. Shoulder-season scheduling sometimes allows for more flexible appointment windows and, occasionally, bundled pricing on add-on services. Ask when you call.
- Bundle dryer vent cleaning with duct cleaning: A dryer vent cleaning job that would cost $149 as a standalone is often priced at $99-$119 when scheduled with a full duct cleaning on the same visit – same truck, same crew, shared mobilization cost. Houston’s humidity means dryer lint compacts faster here than in drier climates; most systems we see in homes south of I-10 should be cleaned annually.
- Get a written estimate before agreeing to anything: This should be standard – and under Haven Standard Clause 1, it is for CleanRun – but it’s worth demanding from any company you call. A written estimate protects you from verbal-only upsells and gives you something to compare. CleanRun also provides a free second opinion on any written estimate another company has given you. Bring the quote; we put our number next to it in writing, at no charge.
- Don’t postpone because of cost – postponing usually costs more: A duct system with 3-4 years of debris accumulation isn’t just running inefficiently; in Houston’s humidity, it’s approaching conditions where microbial growth becomes likely inside the duct liner. Adding antimicrobial treatment to a job that needed only extraction a year ago adds $149-$299 to the invoice. Staying on a 3-to-5-year cleaning cycle generally costs less than addressing what happens when that cycle is skipped.
- Ask what the written price includes, specifically: Confirm that the quote covers every supply run, every return air pathway, and includes the documented photo record. If the answer to any of those is no, that’s not a savings – that’s a partial job at a partial price.

What the Job Actually Looks Like – From First Photo to Last
Price means more when you know what it’s paying for. Here’s what a CleanRun job looks like in a typical Houston home – say, a 2,400-square-foot two-story in the Meyerland area with a single-zone system and 16 supply registers.
The technician – background-checked, uniformed, and identified by name in advance, per Haven Standard Clause 3: Verified Crews – arrives and does a walk-through before touching anything. The plenum is located (typically in the attic in Houston slab construction), and a camera inspection of the main trunk line establishes a baseline. That image is the first photograph in your job record.
Negative-pressure extraction means the Nikro unit creates suction at the main trunk while the Rotobrush agitates each duct run from the register end, loosening debris and pulling it toward the collection point rather than toward your living space. Each supply run is photographed before agitation starts and after extraction is complete. In a 16-register home, that’s 32 minimum documented images – before and after, per run.
Return air pathways and the plenum itself are cleaned last. If the camera found anything that changes the written scope – debris deeper than the initial estimate assumed, evidence of liner breakdown, or anything that warrants a recommendation – it’s photographed, shown to the homeowner, and added to the written record before any additional work is discussed. No verbal-only findings, no pressure decisions.
At the end of the job, the documented photo record is delivered to the customer as a standard deliverable. Not upon request. Every job. That’s what “documented” means at CleanRun – it’s been the practice since the first job Tomas Reyes ran in 2013, and it’s what the 365-Day Done Right Promise is anchored to: if the record doesn’t show the work was done right, we come back and make it right.
Houston-Specific Duct Problems Worth Knowing About
Houston presents a distinct set of duct system conditions that don’t show up in national guides written for a generic market. If you’re researching this topic here, these are the local variables that matter.
Flex Duct Degradation in High-Heat Attics
The majority of Houston residential construction from the 1980s through the 2000s used flexible duct – the corrugated plastic-and-foil tubing that runs from the plenum to each register. In a Houston attic, that material spends four to five months of the year at temperatures above 130 degrees. Over 10-15 years, the inner liner of flex duct begins to delaminate and shed small fibers and particles directly into the air stream. When the camera shows liner debris in a duct run, extraction removes the loose material, but the underlying cause is a duct that is approaching end of life. Cleaning it is still correct – the debris needs to come out – but a technician who doesn’t mention the liner condition isn’t giving you the full picture. CleanRun photographs it and includes the documentation in your job record so you have it for future reference.
Post-Storm Contamination
Houston has absorbed multiple significant flood events since 2015, and a notable percentage of homes in areas like Meyerland, Kingwood, and parts of Spring Branch experienced water intrusion that affected HVAC systems either directly or through secondary humidity effects. Ductwork that was exposed to floodwater, or that sat in an unoccupied home with high indoor humidity for weeks post-event, frequently shows evidence of microbial growth on the inner duct liner that a standard debris cleaning won’t address alone. If your home went through any of the major Houston flood events and the ductwork has not been professionally inspected since, a camera inspection before committing to a cleaning scope is the right starting point.
The Humidity Baseline
Houston averages around 75% relative humidity across the year – one of the highest baselines of any major U.S. metro. That moisture in the air doesn’t disappear when it enters a duct system. Systems with inadequate insulation on duct exteriors, or with small gaps at joints that allow unconditioned attic air to enter, can develop condensation on duct interiors. Condensation plus organic debris is what microbial growth needs. It’s a local variable that makes the antimicrobial treatment step more clinically relevant here than in, say, El Paso or Phoenix.
FAQs – Air Duct Cleaning Cost in Houston
How much does air duct cleaning cost in Houston in 2026?
Air duct cleaning in Houston costs between $299 and $699 for most single-family homes, depending on system size and duct count. A 2,000-square-foot home with one HVAC system and 14-16 registers typically runs $379-$499. Larger homes with two or three systems, or those needing antimicrobial treatment due to mold or post-flood conditions, will run higher. Call (346) 251-8919 for a written price specific to your home’s system – estimates are free.
Is it cheaper to repair or replace ductwork in Houston?
Repair is almost always cheaper unless more than 40-50% of the duct system has failed. Duct sealing and repair in Houston runs $8-$22 per linear foot, depending on accessibility and the repair method required. A full duct system replacement in a Houston home typically runs $2,500-$6,000 or more. When CleanRun’s camera inspection identifies flex duct delamination or joint failures, the written scope will specify exactly which runs need repair – not a blanket recommendation to replace everything. Call (346) 251-8919 and we’ll put the repair vs. replacement comparison in writing.
How often should Houston homes have their air ducts cleaned?
Every 3 to 5 years is the standard recommendation for Houston homes under normal occupancy conditions. Homes with pets, allergy sufferers, post-renovation dust, or post-flood history should move to a 2-to-3-year cycle. Houston’s high humidity and long HVAC operating season both accelerate debris accumulation compared to drier or cooler markets. The photo record from each CleanRun job serves as your baseline – you can compare before photos from your next cleaning against the after photos from this one to see objectively what changed.
Why is one Houston quote $79 and another $450 for the same house?
The $79 quote covers a visit – typically a vacuum pass on accessible registers and a verbal inspection. The $450 quote covers a full negative-pressure extraction of every supply and return run, a documented photo record, and a written scope. These are not the same service. The documented pattern in the Houston market is that the $79 visit converts to a $400-$800 verbal upsell mid-job, without a written price before the work starts. A company that delivers a written price before arrival is telling you something real about how it operates. Call (346) 251-8919 – CleanRun’s estimate is free, written, and delivered before any work starts.
Does CleanRun serve my part of Houston?
CleanRun serves the full Houston metro – from Midtown and Montrose to The Woodlands, Katy, Sugar Land, Pearland, Friendswood, Cypress, Spring, and out to Baytown and League City. If you’re not sure whether your neighborhood falls in our service area, call (346) 251-8919. A live person answers, no voicemail, and they can confirm your address and get you a written estimate on the same call. The home page has a full coverage map for reference.
What does the 365-Day Done Right Promise actually cover?
It covers the work described in the written scope, for 365 days from the job date. If the documented photo record doesn’t reflect what was promised – a duct run that was skipped, a contamination issue that wasn’t addressed, equipment that didn’t perform – CleanRun comes back and makes it right. That’s not a satisfaction-subject-to-manager-approval policy; it’s a written commitment on every job, every time. Tomas Reyes put it in writing on the first job CleanRun ran in 2013, and it hasn’t changed.
