How Much Does Air Duct Cleaning Cost in Katy?

Air Duct Cleaning Near Me in Katy, TX typically costs between $299 and $599 for a standard single-family home, with most jobs landing around $375 to $450 depending on system size and duct condition. That range assumes a straight cleaning on a reasonably maintained system – add-ons like mold treatment, duct sealing, or dryer vent cleaning will push the final number higher. At CleanRun, every price is written down before any panel comes off, so you know the number before the work starts.

Air Duct Cleaning Cost Breakdown (2026)

The table below reflects actual pricing in the Katy, TX market as of 2026. These are the numbers we quote in writing – not opening bids designed to climb once a technician is inside your home.

What These Numbers Include

Every CleanRun job – at every price point – includes a documented photo record of every duct run before and after extraction. That means you receive photographic evidence of what was inside your system, not a verbal summary of what the technician thought he saw. This practice goes back to our first job in 2013 and hasn’t changed. The price you see in writing before we start is the price on the invoice when we leave – that’s Haven Standard Clause 1, and it applies without exception.

We use professional-grade rotary brush and negative-pressure extraction equipment from Rotobrush and Nikro. Negative-pressure extraction means the system runs under a controlled vacuum while the brushes agitate debris loose, so dust and particulate travels into the collection unit rather than back into your living space. Some operators run a shop-vac through a few registers and call it Air Duct Cleaning done. The photo record we deliver tells you immediately whether you’re looking at the results of real extraction or vacuum noise.

Why Katy Pricing Sits Where It Does

Katy’s housing stock is a specific challenge. A large share of homes in this market – particularly in subdivisions like Cinco Ranch, Cross Creek Ranch, Grand Lakes, and the newer Elyson builds – were constructed with long duct runs, multiple zones, and flex duct systems that collect debris at every elbow. The average home we service in Katy has between 14 and 18 supply and return registers. That’s not a number we invented; it’s what the service records from this market show consistently.

Katy also sits in Harris and Fort Bend Counties, where summer humidity regularly exceeds 80 percent and air conditioning systems run nine to ten months a year. A system cycling that often pulls more airborne particulate through the ducts than you’d see in a drier climate. That’s one reason we see heavier build-up here than we do in markets with shorter cooling seasons, and it’s a real factor in pricing – more debris means more time and more extraction passes.

What Affects Air Duct Cleaning Pricing in Katy

• Number of duct runs and registers: This is the single biggest driver. A 1,800 sq ft home in the older parts of Katy near I-10 might have 10 to 12 registers. A 3,500 sq ft home in Firethorne or Elyson can have 22 to 28. Each run requires its own extraction pass, its own before-and-after photo set, and its own brushing cycle. The count matters more than square footage alone.
• Duct material and configuration: Rigid metal duct systems are faster to clean and easier to photograph. Flex duct – which dominates most Katy builds from the 1990s onward – has ribbed interior walls that trap debris and require more time per linear foot. When we find kinked or improperly supported flex duct (more common in older construction near Cinco Ranch West and Kelliwood), those sections take additional time to address properly.
• Years since last service: A system cleaned within the past three to four years typically requires one extraction pass per run. A system that has never been professionally cleaned – or was last touched with a residential shop-vac – often requires two passes and longer agitation time. In Katy, we frequently encounter homes bought at resale where the previous owner’s “duct cleaning receipt” is for a $79 coupon service. The before photos on those jobs speak for themselves.
• Presence of mold or microbial growth: Katy’s humidity creates real mold risk in ductwork, especially in systems where the evaporator coil has run wet or where there’s been any flooding history – which is not a small consideration in a city that experienced significant flood events in 2015, 2016, and 2017. If the camera shows visible microbial growth, we scope and quote remediation separately before touching anything. Antimicrobial treatment with Abatement Technologies product is a separate line item, not bundled into the base price without discussion.
• Accessibility: Systems with attic air handlers in older subdivisions along Highway 90 or near Old Katy Road can be harder to access than those in newer construction with dedicated utility closets. Crawl-space ductwork, while less common in Katy than in older Houston neighborhoods, adds time when it exists. We note access difficulty in the written quote before work starts – not after.
• Add-on services bundled with the job: Dryer vent cleaning, coil cleaning, and duct sealing are each priced separately and quoted in writing. Bundling them with a cleaning job usually reduces the total compared to scheduling them independently, but we don’t assume you want them – we photograph what we find and present the options with prices attached.

How Katy Compares to Surrounding Markets

Pricing for Air Duct Cleaning in Katy runs slightly higher than some inner-Houston neighborhoods, mostly because of home size. The average conditioned square footage in Katy’s master-planned communities is larger than the Houston metro average, and that translates directly to more duct runs per job. Sugar Land, Pearland, and The Woodlands sit in a similar range for similar-sized homes.

Where Katy is distinct is in the volume of homes built in the 1995 to 2015 window with extensive flex duct systems and multiple air handlers – some larger homes in Grand Lakes and Seven Meadows have two or three air handlers serving separate zones for Commercial Duct Cleaning – some larger homes in Grand Lakes and Seven Meadows have two or three air handlers serving separate zones. Each air handler has its own return plenum (the main collection box that draws air back to the unit) and its own network of supply runs. A two-handler home is effectively two jobs in terms of equipment time, and the written quote will reflect that clearly.

The $79 Coupon Problem in Katy

It would be incomplete to write a pricing guide for Katy without addressing what’s been driving the market here for years. A pattern of low-ball coupon pricing – $49, $69, $79 for a “whole house” cleaning – circulates heavily in this market, particularly through door-hanger campaigns in Cinco Ranch and cross-promotional mailers in the newer Elyson and Cane Island developments.

The model works like this: a technician arrives, runs a shop-vac or portable unit through a handful of accessible registers, and then presents an upsell menu – mold treatment, “sanitizing fog,” duct sealing, or a filtration upgrade – that brings the actual invoice to $400 to $800. The original $79 was the entry fee, not the price.

CleanRun’s written upfront pricing exists specifically because of this pattern. You get a dollar figure before any panel comes off. If the camera finds something unexpected – a debris blockage at the plenum, visible microbial growth at an elbow, a collapsed duct section – we show you the photo and quote the additional scope in writing before doing anything about it. That’s Haven Standard Clause 1, and it’s not negotiable on any job we run.

If you have a written estimate from another company, we’ll put our number next to it in writing – free, no obligation. That’s our Free Second Opinion, and it’s available to anyone in the Katy market who wants an honest comparison.

How to Save on Air Duct Cleaning in Katy

Bundle Services When the Truck Is Already There

The largest single cost on any Full System Cleaning job is drive time and setup. When a CleanRun technician is already on-site with Rotobrush and Nikro equipment running, adding dryer vent cleaning or coil cleaning costs a fraction of what it would as a standalone visit. If your dryer vent hasn’t been cleaned in two years – and in Katy’s humidity, lint accumulates faster than you’d expect – combining it with a duct cleaning appointment is the most cost-effective time to do it.

Schedule During Off-Peak Periods

Demand for duct cleaning in Katy peaks twice: spring (March through May, before cooling season starts) and early fall (September through October, after the heaviest AC use). Scheduling in January, February, or November typically means faster booking and, in some cases, reduced pricing on bundled add-ons. Call (346) 666-7165 to ask what’s available – you’ll speak to a live person, not a voicemail.

Don’t Wait Until the System Is Heavily Fouled

This sounds counterintuitive as a savings tip, but it’s real: a system cleaned on a three-to-four-year cycle costs less per visit than a system cleaned once every eight to ten years. Heavy debris build-up requires multiple extraction passes per run, longer agitation cycles, and sometimes a second visit if the blockage is significant. The before photos on neglected systems – which we photograph at every job – consistently show the cost of deferred maintenance.

Use the Free Second Opinion

If you’ve already received a written estimate from another Katy duct cleaning company, bring it to us. We’ll put a CleanRun written price next to it at no cost. This is not a sales tactic – it’s a direct comparison, in writing, that you can evaluate on your own. Call (346) 666-7165 to arrange it.

Ask What the Photo Record Shows Before Agreeing to Add-Ons

Any add-on service we recommend comes with a photograph of the condition that warrants it. If a technician recommends antimicrobial treatment, you’ll see the image that prompted the recommendation before you agree to the price. If you’re comparing CleanRun to another company that’s recommending the same add-on without showing you the evidence, that’s a meaningful difference worth factoring in.

What You Actually Receive at the End of a CleanRun Job

This section belongs in a pricing guide because what you receive for the money is part of the value calculation. After every job in Katy, the customer receives:

• A written scope of work completed, listing every duct run serviced by location
• A documented photo record – before and after images of every duct run, delivered as a standard job deliverable, not a premium add-on
• A written copy of the 365-Day Done Right Promise: if the work isn’t right, we make it right, in writing, not subject to manager approval
• The final invoice matching the written price quoted before work began – Haven Standard Clause 1, every time

We’ve served more than 52,000 homes since 2013, every one of them with a written price before work started and a documented photo record when the crew left. The photo record is not something we added for marketing; it’s how we hold ourselves accountable to the work we describe on pages like this one.

FAQs – Air Duct Cleaning Cost in Katy, TX

How much does air duct cleaning cost in Katy, TX?

Most Katy homeowners pay between $299 and $599 for a full air duct cleaning, with the majority of single-family homes in the $375 to $450 range. Homes with 20 or more registers – common in the larger builds in Grand Lakes, Cinco Ranch, and Elyson – typically run $450 to $650. Every CleanRun price is delivered in writing before any work starts. Call (346) 666-7165 for a written estimate specific to your home’s system.

Is it cheaper to clean ducts in winter than in summer in Katy?

Generally, yes. Demand in Katy is lowest between November and February, before the spring HVAC rush. Scheduling during that window typically means faster availability and, on bundled jobs, better pricing on add-ons like dryer vent cleaning or coil cleaning. The base duct cleaning price doesn’t fluctuate dramatically by season, but the savings on same-day bundling are real. Call (346) 666-7165 to check current availability.

Why is some duct cleaning priced at $79 and CleanRun is priced higher?

A $79 price point covers a shop-vac pass through a few accessible registers. It does not cover negative-pressure extraction through every duct run, rotary brush agitation, a documented photo record of every run, or a written warranty on the work. In Katy specifically, we regularly see systems that received a “$79 cleaning” where the before photos – taken at our job, years later – show the original debris still packed at the first elbow from the plenum. The price difference reflects whether actual extraction happened. Our written price before work starts is the whole point of Haven Standard Clause 1 – you know exactly what you’re paying for before anything starts.

Does air duct cleaning cost more if there’s mold in the ducts?

Yes, and it should. Mold remediation in ductwork is a separate scope from cleaning and is priced separately, starting around $250 and going higher depending on the affected area. In Katy, microbial growth in ductwork is more common than in drier climates – the combination of high humidity, long AC run times, and the flood history in parts of the city creates real conditions for it. If the camera shows visible growth, we photograph it and quote the remediation in writing before touching it. You decide whether to proceed. Call (346) 666-7165 if you have concerns about what might be in your system.

How often should Katy homeowners have their ducts cleaned?

Every three to four years is the standard recommendation for most Katy homes, and that interval should shorten to two to three years if there are pets, allergy sufferers, recent renovation work, or any history of flooding in the structure. Katy’s climate means systems cycle more hours per year than in northern markets, which accelerates debris accumulation. A home in Cinco Ranch running its AC from March through November – roughly nine months – pulls significantly more airborne particulate through the duct system than a comparable home in a shorter cooling season. The before photos from first-time service on Katy homes that have gone eight to ten years without cleaning consistently show a debris layer at the plenum and at the first elbow of each run that restricts airflow measurably.

What’s included in CleanRun’s price that other companies charge extra for?

The documented photo record – before and after images of every duct run – is included in the base price on every CleanRun job, not an upgrade. The 365-Day Done Right Promise is included in writing on every job, not offered as a premium tier. The written price before work starts is standard, not an option you request. Most companies charge separately for the documentation or simply don’t provide it. The add-ons that carry a separate line item are antimicrobial treatment, coil cleaning, duct sealing, and dryer vent cleaning – each quoted in writing before you agree to them.
