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 Quality & Sanitizing for Leander Homeowners
Air quality and sanitizing service in Leander typically costs $280-$780 for whole-home treatment depending on system size and which contaminants are present, and most jobs are completed in a single visit with a written price agreed before any work begins. Call (737) 252-1285 for a free estimate with no obligation.
Since 2013, CleanRun Air Duct Cleaning Leander has treated the air systems in more than 52,000 homes, every one with a written price delivered before a single panel came off and a documented photo record delivered when the crew left. Leander’s rapid growth since 2015 has brought thousands of new homes into neighborhoods like Crystal Falls, Travisso, and Palmera Ridge, many built during the construction boom with HVAC systems that have never been properly sanitized. The Hill Country climate here means high pollen counts in spring, mold-friendly humidity in summer, and dust intrusion year-round from the limestone soils that surround the city. We have found bacterial growth in the plenum (the main distribution box above the furnace) of homes less than four years old in Leander’s newer subdivisions, and we’ve documented mold colonies in the flex duct of homes near the San Gabriel River where seasonal moisture seeps into crawl spaces. Our technicians are background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews. Every job is backed by the 365-Day Done Right Promise, and we publish our license number on every page because credentials should be visible, not buried.
What Our Air Quality & Sanitizing Service Includes
Mold Treatment
Mold treatment targets fungal colonies growing inside ductwork, on the evaporator coil, or in the plenum, where spores circulate through every room each time the blower cycles. In Air Quality & Sanitizing - Leander, we regularly find mold in homes near water features or with crawl-space duct runs that draw humid air during summer months, particularly in the Crystal Falls area where seasonal drainage patterns create persistent dampness. Our process uses negative-pressure extraction (suction that contains debris during cleaning) combined with EPA-registered antimicrobial application, and every treated run is photographed before and after so you can verify the colony was addressed, not just disturbed.
Bacteria Sanitizing
Bacteria sanitizing eliminates microbial contamination that standard duct cleaning leaves behind, particularly important after water intrusion, pest activity, or prolonged system inactivity. We treat the entire air handler, including the blower assembly and drain pan, with professional-grade sanitizers applied through foggers that reach surfaces mechanical cleaning cannot touch. In Leander homes built 2015-2020, we’ve documented elevated bacterial loads in systems where the original builder-grade filter was never upgraded, allowing organic material to accumulate in the duct runs for years.
Odor Removal
Odor removal addresses persistent smells that originate inside the HVAC system rather than in the living space, including pet dander accumulation, smoke residue, and the musty scent of microbial growth. We identify the source run using borescope inspection (a camera on a flexible cable fed through the duct), then apply targeted treatment rather than masking agents. Homeowners in Leander’s older neighborhoods near Bagdad Road have called us after years of “air freshener solutions” that never reached the actual contamination deep in the trunk lines.
UV Light Installation
UV light installation places germicidal ultraviolet lamps at the evaporator coil or in the return plenum, where continuous exposure prevents mold and bacterial growth on wet surfaces. We size the lamp to your system tonnage and install it with a sight glass so you can verify it’s operating without disassembling anything. In Leander’s cooling-intensive climate, where AC systems run eight months or more, UV lamps reduce the biofilm that builds on coils and restricts airflow, a problem we’ve photographed in dozens of local homes where energy bills rose before the owner noticed any air quality issue.
Air Purifier Install
Whole-home air purifier installation adds dedicated filtration or electronic air cleaning at the central return, treating all air passing through the system rather than relying on portable units in individual rooms. We install Honeywell and Aprilaire systems sized to your home’s square footage and existing duct static pressure (the resistance the blower must overcome). For Leander homes in Travisso and other large-floorplan communities near our Air Quality & Sanitizing in Cedar Park service area, a properly sized whole-home purifier replaces the need for multiple portable units that consume outlet space and require constant filter purchases.
Allergen Reduction
Allergen reduction combines mechanical cleaning with targeted treatment for the pollen, dust mite debris, and pet dander that accumulate in ductwork and recirculate during peak seasons. We focus on the return duct runs where debris concentrates, using Rotobrush contact cleaning with HEPA-filtered vacuums that capture particles as small as 0.3 microns. Leander’s cedar pollen season, which peaks December through February, drives significant demand for this service as homeowners discover their “allergy symptoms” persist indoors because the HVAC system has become a reservoir for the very particles they are trying to escape.

Brands We Service for Air Quality & Sanitizing
We install and service air quality equipment from Honeywell, Aprilaire, and Guardsman, and we maintain professional-grade cleaning and treatment systems from Rotobrush and Nikro on every truck. Our crews have installed hundreds of Honeywell whole-home media air cleaners in the Leander area, and we stock the replacement filters so you’re not hunting for the correct size online. Aprilaire steam and bypass humidifiers paired with their air purifiers are common in the higher-end builds of Travisso and Crystal Falls, and we service these integrated systems with the factory-specified test procedures rather than generic troubleshooting.
Whether your home has Honeywell, Aprilaire, Guardsman, or any other make of air quality equipment, we can service it, repair it, or replace it with a written scope and price before any work begins. We do not install equipment we cannot support with documented manufacturer procedures, and we do not recommend products we cannot explain in plain language. If you are considering a system from a brand we have not named here, call us for a free second opinion on the proposal you’ve received.
BeforeAfterSigns You Need Air Quality & Sanitizing Right Now
- Persistent musty or sour smell when the HVAC cycles. This indicates microbial growth on wet surfaces inside the system, typically the evaporator coil or drain pan, and it will worsen until the source is treated. In Leander’s humid summers, we see this most often in homes where the condensate drain line has partially clogged, creating a reservoir of standing water.
- Increasing allergy symptoms indoors during peak pollen season. If your eyes water and your nose runs inside the house even with windows closed, your ductwork may be recirculating accumulated pollen and dust mite debris rather than filtering it. We have documented return plenums in Leander homes with debris layers thick enough to restrict airflow by 15 percent or more.
- Visible mold or staining around ceiling registers or the air handler. These are the external signs of an internal problem that has already progressed significantly; the colony you see represents a fraction of what exists deeper in the system. Homes near the San Gabriel River or in low-lying sections of Palmera Ridge are particularly susceptible due to higher ambient moisture.
- Recent water intrusion, roof leak, or pest activity in the ductwork. Any of these events introduces organic material and moisture that support bacterial and fungal growth, and standard drying is rarely sufficient for the interior of duct runs. We have treated systems in Leander where squirrels or raccoons accessed crawl-space ducts, leaving contamination that circulated odor and bacteria for months before the homeowner identified the source.
- Family members with asthma, COPD, or compromised immune systems. For these households, air quality is not a comfort issue but a health priority, and the standard 1-inch fiberglass filter common in builder-grade systems is inadequate. We have installed whole-home purification in Leander homes specifically to reduce the particulate load for residents with respiratory conditions, with documented before-and-after particle counts available as part of the job record.
Our Air Quality & Sanitizing Process - Step by Step
- 1
Written estimate before arrival. When you call (737) 252-1285, we gather information about your home’s size, system type, and symptoms, then deliver a written price range by text or email before we dispatch. Haven Standard Clause 1 requires this; there is no “call for a quote” in our process because the quote should already be in your hand.
- 2
On-site inspection with borescope documentation. Our technician arrives in a marked vehicle, uniformed, and identified by name under Haven Standard Clause 3. We feed a borescope camera through representative duct runs to show you what exists inside, and we photograph the evaporator coil, plenum, and any areas of concern. These images become part of your documented photo record.
- 3
Written scope confirmation. If the inspection reveals conditions that affect the price (additional contamination, access limitations, required repairs), we present a revised written scope before any treatment begins. You approve the exact work and exact price; no open-ended authorizations, no per-vent add-ons, no surprises when the invoice arrives.
- 4
Contained treatment and cleaning. We seal registers and establish negative-pressure extraction to prevent debris migration during work. Mold treatment, bacteria sanitizing, or odor removal is applied with foggers or contact applicators as specified, and UV or purifier installations follow manufacturer procedures with serial numbers recorded. Every run is photographed after treatment.
- 5
Delivered documentation and warranty. You receive the complete photo record, the final written scope, and the 365-Day Done Right Promise in writing before the technician leaves. If we installed equipment, you receive the warranty registration and our direct contact for any future service. The truck does not depart until you have everything in hand.
How Much Does Air Quality & Sanitizing Cost in Leander?
A typical Air Quality & Sanitizing pricing for bacteria sanitizing or odor removal in Leander runs $280-$450 for a single system up to 2,500 square feet, while mold treatment with full containment and antimicrobial application ranges from $480-$780 depending on the number of affected runs and whether the evaporator coil requires separate access. UV light installation with a properly sized lamp and power supply typically falls between $320-$580, and whole-home air purifier installation ranges from $680-$1,200 for media filtration units or $890-$1,450 for electronic air cleaners, with the final price determined by your home’s existing duct configuration and electrical access.
Several factors move the price within these ranges. Homes with multiple HVAC zones require separate treatment of each system. Access limitations, such as ducts buried in spray-foam insulation or located in sealed crawl spaces, add labor time. The severity of contamination affects chemical and labor requirements; a light bacterial fogging is not the same work as treating a plenum with visible mold colonization. Equipment brand and features matter for purifier installations; a basic Honeywell media cabinet costs less than an Aprilaire electronic model with onboard air quality monitoring.
To avoid overpaying, reject any quote that uses per-vent pricing, which incentivizes the technician to find as many vents as possible. CleanRun charges one flat price per system, agreed in writing before work starts, because your home’s ductwork is a connected network, not a collection of separate items. Also reject any proposal that does not include a written scope with specific treatment methods; “sanitizing” without stating the product and application method is not a quote, it is a hope. Our free estimate includes the full written scope, and our Free Second Opinion on Any Written Estimate means you can bring us a competitor’s proposal and we will put our number next to it with no cost or obligation.
Every estimate includes the documented photo record, the written warranty, and all labor and materials. There are no trip charges, no disposal fees, and no equipment-rental surcharges. What we quote is what you pay.

Frequently Asked Questions - Air Quality & Sanitizing in Leander
Air quality and sanitizing targets biological contaminants, mold, bacteria, and odors with EPA-registered treatments and specialized equipment, while standard duct cleaning removes loose debris and dust through mechanical agitation and vacuum extraction. Duct cleaning improves airflow and reduces particulate load; sanitizing addresses the living or chemically bound contaminants that cleaning alone cannot remove. In Leander’s climate, and for Air Quality & Sanitizing in Georgetown area homes as well, we often recommend both services in sequence for homes with visible mold or persistent odors.
Most residential treatments take two to four hours for a single system, with UV or purifier installations adding one to two hours depending on electrical access and duct configuration. Mold remediation with full containment and multiple affected runs can extend to a full day. We give you a specific time estimate in your written scope, not a range that leaves you waiting.
Bacteria sanitizing and odor removal typically run $280-$450, mold treatment $480-$780, UV installation $320-$580, and whole-home purifier installation $680-$1,450 depending on system size and features. Every price is written and agreed before work begins under Haven Standard Clause 1. Call (737) 252-1285 for an exact quote; estimates are free.
