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 HVAC Cleaning Cost in Leander, TX?
HVAC Cleaning services in Leander, TX typically run between $299 and $699 for a standard single-family home, with most jobs landing around $400-$500 when the system is cleaned on a regular schedule. Homes with larger floor plans, older flex-duct layouts common in Leander’s 1990s-2000s subdivisions, or systems that haven’t been cleaned in five or more years will land toward the higher end of that range. At CleanRun, the written price is delivered before any panel comes off – always, on every job, no exceptions.
HVAC Cleaning Cost Breakdown (2026)
These are real dollar ranges for the Leander market, based on what we actually quote and invoice on jobs throughout Leander and the surrounding Williamson County area. Every number below reflects what a homeowner with a documented written quote should expect to pay – not a bait-and-drop price inflated after the crew is already in your home.
| Service Component | Typical Price Range | Notes |
|---|---|---|
| Supply and return duct cleaning (up to 10 vents) | $299 - $399 | Negative-pressure extraction with Nikro or Rotobrush equipment |
| Per additional vent (beyond 10) | $15 - $25 per vent | Most Leander homes built after 2000 have 12-20 supply registers |
| Air handler / blower compartment cleaning | $75 - $125 | Often bundled; priced separately on heavily fouled units |
| Evaporator coil cleaning | $100 - $175 | Coil condition is photographed before and after |
| Dryer vent cleaning (add-on) | $99 - $149 | Frequently discounted when bundled with full HVAC cleaning |
| Sanitizing treatment (EPA-registered) | $75 - $150 | Applied with Abatement Technologies fogger; not required on every job |
| Duct repair / sealing (per linear foot) | $8 - $18 per foot | Common in Leander attic runs where flex duct has separated at collars |
| Full system cleaning, 2,000-2,500 sq ft home | $399 - $549 | Most common job size in Leander neighborhoods like Crystal Falls and Block House Creek |
| Full system cleaning, 2,500-4,000+ sq ft home | $549 - $699+ | Applies to newer builds in Mason Hills and Travisso, which often have two systems |
What pushes the price up – and what keeps it down
The single biggest cost driver in Leander is duct count and system configuration. A home in Block House Creek built in 2003 with one 2,200-square-foot floor plan and a straightforward single-unit system is a predictable job. A newer construction in Travisso or Mason Hills with two HVAC systems, zoned dampers, and 22+ registers is a longer day and a higher invoice – and that’s fair. More ductwork takes more time and more equipment passes.
The second driver is condition. Leander’s climate doesn’t help here. The combination of high summer humidity and the cedar and oak pollen seasons means ducts accumulate biological debris faster than in drier climates. When our camera shows a significant debris layer at the first elbow – the kind that took five or more years to build up – the cleaning takes longer because negative-pressure extraction has to be methodical to actually clear the run, not just the visible register face. A system cleaned every three to four years doesn’t have that problem. One that hasn’t been touched since the home was built in 2008 often does.
What keeps costs down: scheduling during shoulder season (spring and fall), bundling dryer vent cleaning with the HVAC job, and having accessible panel access to the air handler. When a technician can photograph, clean, and re-inspect each duct run without working around obstacles, the job runs efficiently and that efficiency stays in the homeowner’s pocket.
What Affects HVAC Cleaning Pricing in Leander
- Home size and duct count: Price scales with the number of supply and return registers, not just square footage. A 2,800-square-foot Leander home with an open floor plan might have 14 vents; a 2,200-square-foot home with more rooms might have 18. The camera goes down every run, so every register adds to the scope.
- Number of HVAC systems: A significant share of Leander homes built after 2015 – especially in Travisso and north Crystal Falls – have two-unit systems for two-story floor plans. Each unit means a separate air handler, separate plenum (the central distribution box the ducts branch from), and separate cleaning scope. Expect the price to be structured accordingly.
- Duct material and age: Older flex duct, common in Leander homes built in the 1990s through the early 2000s, is more fragile during cleaning and sometimes reveals separation at the collar joints during inspection. Rigid sheet metal duct in newer builds is more durable and often faster to clean thoroughly.
- Time since last cleaning: A system cleaned three years ago is a maintenance job. A system that has never been cleaned since construction – and in Leander’s dusty limestone-soil environment, construction debris often makes it past the filter during the build phase – is a remediation job. The camera tells the story before the price does.
- Attic configuration and access: Leander’s summer heat means most duct runs are in the attic. When attic access is standard and the ducts are within reach of the equipment, the job is straightforward. When joists are low, insulation is deep, or duct runs are tucked into corners, the job takes longer and the price reflects that honestly.
- Add-on services selected: Sanitizing, evaporator coil cleaning, and dryer vent service each add to the invoice but not proportionally when bundled. A homeowner who wants all three done in one visit will pay less than if each were scheduled separately – the truck is already there, the equipment is already set up.
BeforeAfterWhy the $79 Coupon Doesn’t Mean What It Looks Like
Leander homeowners searching for HVAC Cleaning in Leander will encounter a recognizable pattern: a national or regional brand advertising a $69 or $79 whole-home special. The offer is genuine in the narrow sense that a truck will show up and a shop-vac will make noise near your registers. What changes is what happens next.
The typical escalation looks like this: the base price covers a fixed number of vents (often 10, sometimes fewer), and each additional register is billed at $25-$35. The air handler compartment is an upsell. The evaporator coil is another. Sanitizing, which the technician frames as necessary based on what they find, is another. By the time the invoice is written, a Leander home with 16 vents and two systems is looking at $350-$500 anyway – except the homeowner didn’t have a written price before the crew started pulling panels.
CleanRun’s position is simple: Haven Standard Clause 1 requires a written price before any work starts, on every job. That price doesn’t change when the technician opens the air handler and finds what’s there. If scope changes – if the camera finds a separated duct run that wasn’t in the original quote – that conversation happens in writing before any additional work begins. The before-and-after photo record, included as a standard deliverable on every job, is what makes the documented result verifiable rather than assumed.
Tomas Reyes built CleanRun on that structure in 2013, and it’s how we’ve served 52,000+ homes since. The photo doesn’t lie about whether a duct was actually cleaned.
How to Save on HVAC Cleaning in Leander
Schedule in the off-peak window
Demand for HVAC cleaning in Leander peaks in late spring (April-May, before the first 100-degree week) and again in early fall (September-October, when residents start thinking about the heating season). March and November are typically lighter scheduling months. Booking during those windows doesn’t guarantee a lower price – CleanRun uses the same written pricing year-round – but it does mean more scheduling flexibility and shorter lead times.
Bundle services on one visit
If your dryer vent is overdue, or if you’re considering a sanitizing treatment, combining those with the HVAC cleaning on the same visit is the most cost-efficient structure. The truck is already there. The equipment is already set up. Bundled pricing reflects that reality. Call (737) 252-1285 and ask what a bundled scope looks like in writing before you commit.
Get a second opinion on any written estimate
CleanRun offers a free second opinion on any written estimate from a competitor. Bring the other company’s quote and we’ll put our price next to it in writing. This service costs nothing and requires no obligation. If our number is higher, you’ll know why. If it’s lower, you’ll have documentation to compare both scopes.
Keep your filter on schedule
A MERV-8 or MERV-11 filter replaced every 60-90 days in a Leander home (more frequently during cedar fever season in January-February) meaningfully slows the rate of debris accumulation in the duct runs. That doesn’t eliminate the need for professional cleaning, but it can extend the interval between full cleanings from two years to three – and over a decade of homeownership, that’s real money.
Don’t wait until there’s a problem
The most expensive HVAC cleaning jobs we see in Leander aren’t the big houses. They’re the medium-sized homes where the system ran for eight or ten years without a cleaning, the flex duct separated at two collar joints, and the evaporator coil is carrying a biological film that’s cutting airflow by 20%. That job costs more because it is more work. A maintenance cleaning on a three-year cycle is always cheaper than a remediation cleaning after a decade of deferred service.
What the Cleaning Actually Involves – In Plain Language
HVAC cleaning isn’t a single action. It’s a sequence of documented steps, and understanding what each step is helps a homeowner know whether they’re getting real work or theatrical noise.
Negative-pressure extraction is the core method: a Nikro or Rotobrush vacuum system creates a strong, continuous suction inside the duct system, and a technician uses a rotating brush or compressed-air whip tool to dislodge debris from the walls of each duct run while the vacuum pulls it toward a collection point. This is different from a shop-vac held near a register, which disturbs surface dust without removing the debris layer clinging to the duct walls.
The plenum – the main distribution box that the ducts branch from, located at the air handler – is cleaned separately because debris concentrates there. In a Leander attic installation, the plenum is typically the dustiest component in the system, especially if the filter has been undersized or infrequently changed.
The evaporator coil sits inside the air handler and is responsible for cooling the air before it’s distributed. In Leander’s humid summers, the coil is often damp, which makes it a collection point for biological debris. CleanRun photographs the coil before cleaning, cleans it with appropriate chemical, and photographs it again. The customer receives both photos as part of the standard job record.
The blower compartment houses the fan motor that moves air through the system. Dust accumulation here reduces motor efficiency and can shorten motor life. It’s cleaned as part of a full HVAC cleaning job, not treated as an optional add-on.
When a job is done, the customer receives a documented photo record of every duct run – before and after, named by register location. That record is the physical evidence that the work was done, and it’s the reason CleanRun has held this practice since the first job in 2013.
Leander-Specific Factors That Affect What You’ll Find Inside Your Ducts
The cedar and live oak tree cover throughout Leander, particularly in older areas near Crystal Falls Parkway and the 183A corridor, generates significant airborne particulate during January and February cedar fever season and again during oak pollen in March and April. Homes in these areas with standard 1-inch panel filters often show visible pollen layer accumulation at the supply registers by March, and that material migrates into the duct runs over multiple seasons.
The limestone caliche soil common throughout Williamson County kicks up fine mineral dust during the dry summer months. Homes near active construction – and there has been consistent residential construction across Leander’s western expansion zones since 2018 – see elevated particulate counts that load filters faster and accumulate in ductwork at a higher rate than in already-developed neighborhoods.
Newer construction in Leander, particularly the master-planned communities that have expanded along Ronald Reagan Boulevard and Lakeline Boulevard, tends to have modern rigid duct systems with better sealing. But new construction also means construction dust that made it into the system during the build phase – a common finding when we photograph the plenum on a home that’s three to five years old and has never been cleaned. That’s not the homeowner’s fault; it’s a standard result of how homes are built.
Homes in the older Leander neighborhoods near Hero Way and Crystal Falls that were built in the mid-1990s through early 2000s often have flex duct that has aged past its optimal service life. Flex duct is not designed to last indefinitely, and after 20+ years in an Austin-area attic – where summer temperatures regularly exceed 130 degrees – the inner liner can degrade. When our camera finds that, we document it and present a repair scope in writing before any work begins. Sometimes the finding changes the scope of the job. The written price is always updated before work continues.
The 365-Day Done Right Promise – What It Actually Means
CleanRun backs every HVAC cleaning job with the 365-Day Done Right Promise: if the work isn’t right, we make it right. That commitment is in writing on every job – it’s not a verbal reassurance, and it’s not subject to manager approval on a case-by-case basis.
In practice, what triggers the promise is a specific finding, not a general feeling. If a customer notices a register that was documented as cleaned but later shows evidence that the run wasn’t fully cleared – something visible in the before-and-after photos – we return and re-clean it at no charge. The photo record is what makes this enforceable. Without documentation of what was done, a guarantee is just a sentence. With documentation, it’s a standard that can be verified.
This matters in the context of pricing because it changes what the price actually buys. A $79 coupon job with no documentation and no follow-up commitment is a different product than a $399 written-price job with a photo record and a 365-day guarantee. The dollar figures overlap when you add the upsells to the coupon job. The documentation and accountability don’t overlap at all.
CleanRun’s Equipment – Why It Matters to You
The equipment used on a job determines what’s physically possible during the cleaning. CleanRun uses professional-grade tools that customers can look up independently: Rotobrush, Nikro, and Abatement Technologies for duct cleaning and sanitizing; Honeywell, Aprilaire, and Guardsman for filtration and air quality components.
Rotobrush and Nikro systems are recognized by NADCA (the industry’s professional association) as appropriate for source removal cleaning – the category of cleaning that actually removes debris from duct walls, as opposed to disturbing surface dust near the register face. Abatement Technologies foggers are used for sanitizing applications when warranted, applying EPA-registered treatment throughout the duct system.
The reason this matters in a pricing conversation: equipment affects both the quality of the result and the time required to achieve it. A professional-grade negative-pressure system cleaning a 16-vent home in Leander takes two to three hours done correctly. A shop-vac takes less time and produces a less documented, less verifiable result. The price difference between those two approaches is real, and the photo record is what makes the difference visible.
FAQs: HVAC Cleaning Cost in Leander, TX
How much does HVAC cleaning cost in Leander, TX in 2026?
HVAC cleaning in Leander runs $299-$699 for most single-family homes, with the majority of jobs in the $399-$549 range for homes between 2,000 and 2,500 square feet. Homes with two HVAC systems – common in Leander’s newer master-planned communities – or systems that haven’t been cleaned in more than five years will land at the higher end. CleanRun delivers the written price before any work starts, so the number you see before the technician opens a panel is the number on the invoice. Call (737) 252-1285 for a written estimate – it’s free.
Is HVAC cleaning worth it in Leander, where the heat runs the system so hard?
Yes, and the heat is part of why. An HVAC system in Leander runs significantly more hours per year than the same system would in a cooler climate – often 2,000+ hours annually. More runtime means more air moved through the duct system, which means faster debris accumulation and more frequent opportunities for the evaporator coil to collect biological material in the humid summer months. A system working against a debris-clogged duct or a fouled coil uses more energy to move the same volume of air. Most Leander homeowners on a three-to-four-year cleaning cycle see the job as a maintenance cost, not a luxury.
How often should I clean my HVAC ducts in Leander?
Every three to four years is the practical interval for most Leander homes. Homes near active construction zones in western Leander, homes with pets, or homes where a family member has documented respiratory sensitivities often benefit from a two-to-three-year cycle. Cedar fever season in January-February is a useful scheduling trigger – the pollen load on Leander’s air during that period is among the highest in the country, and a post-season cleaning captures what accumulated during peak particulate months.
What’s the difference between HVAC cleaning and duct cleaning?
HVAC cleaning covers the full system: duct runs, supply and return registers, the plenum (the main distribution box), the blower compartment, and the evaporator coil. Duct cleaning, as the term is commonly used, refers specifically to the duct runs and registers without necessarily including the air handler components. In Leander’s climate, where the evaporator coil operates in humid conditions for six or more months a year, cleaning the coil as part of the full system job produces a meaningfully better result than cleaning only the ducts. Ask specifically what’s included before agreeing to a price – that distinction is why CleanRun itemizes every component in the written scope.
Can I combine dryer vent cleaning with HVAC cleaning to save money?
Yes, and it’s the most common bundled service we do in Leander. Dryer vent cleaning priced alone runs $99-$149; bundled with a full HVAC cleaning job, the combined price is typically lower than the two services booked separately because the truck and crew are already on-site. The dryer vent is documented with a before-and-after photo record under the same standard as the HVAC job. Call (737) 252-1285 to get the bundled number in writing before scheduling.
Why does CleanRun cost more than the $79 coupon I see advertised?
The $79 entry price typically covers fewer registers than most Leander homes have, and each additional register, the air handler cleaning, and any sanitizing are billed as upsells after the technician is already in your home. By the time the invoice is written on a standard Leander home, the total often falls between $350 and $550 – without a written price agreed to in advance or a photo record of the work delivered afterward. CleanRun’s written price covers the full documented scope agreed to before any work starts, and the 365-Day Done Right Promise and before-and-after photo record are included on every job, not added for extra. The comparison isn’t always the entry price; it’s what each option actually delivers at the end of the visit.
