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.
Trusted Air Quality & Sanitizing for Austin Homeowners
Air Quality & Sanitizing pricing for whole-home treatment in Austin typically runs $350-$850 depending on scope, covering mold, bacteria, allergens, and persistent odors inside your ductwork and HVAC system. We’re CleanRun Duct Repair & Cleaning, independently owned and operated under the Haven Standard since 2013, and we’ve documented the inside of over 52,000 homes with before-and-after photos of every duct run. In Austin’s humid subtropical climate, where summer indoor humidity regularly pushes past 60% and winter temperature swings force constant HVAC cycling, untreated duct systems become reservoirs for microbial growth that standard filter changes cannot reach. Call us at (737) 243-9544 for a written price before any work starts, every time.
Our crews deliver our Air Quality & Sanitizing in Austin throughout core neighborhoods and inner suburbs, from Tarrytown and Clarksville to East Austin and South Congress, and we regularly find conditions specific to this market: pollen infiltration from Hill Country cedar and oak, moisture accumulation in crawl-space duct runs common in 2015-2020 builds, and construction debris left in new-construction homes from the 2019-2022 building boom. Every job we perform includes a Documented Photo Record of every duct run, delivered to you as part of the standard job record, and every technician is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews.
What Our Air Quality & Sanitizing Service Includes
Mold Treatment
Mold treatment targets visible and hidden fungal growth inside ductwork, on the evaporator coil, and within the plenum, the large central chamber where conditioned air collects before distribution. In Austin and nearby communities, we regularly treat Aspergillus and Cladosporium species that thrive in the 70-85°F, humid conditions of poorly sealed return plenums, particularly in homes with crawl-space duct runs in neighborhoods like Allandale and Crestview - and we also provide our Air Quality & Sanitizing in Cedar Park. Our process begins with a written scope and price, includes HEPA-contained negative-pressure extraction to prevent cross-contamination, and concludes with an EPA-registered antimicrobial application and your photo documentation showing the treated surfaces.

Bacteria Sanitizing
Bacteria sanitizing applies EPA-registered disinfectants to interior duct surfaces, coil fins, and drain pans where biofilm accumulates, the slimy layer of microorganisms that standard cleaning cannot remove. We perform this service most often in Austin homes with pets, recent water intrusion, or HVAC systems that have run continuously during 100°F+ stretches without proper dehumidification, conditions we see frequently in Mueller development homes and Westlake Hills properties with multi-zone systems. The sanitizing agent we select is matched to the surface material, metal or fiberglass duct board, and every application is documented in your photo record with time-stamped before and after images.

Odor Removal
Odor removal addresses persistent smells that originate inside the duct system rather than from temporary sources like cooking or pets, the musty, sour, or chemical odors that return within hours of airing out a room. In Austin, we trace these to rodent activity in attic duct runs, particularly common in older homes in Hyde Park and Rosedale with mature tree canopy and roof access points, or to VOC off-gassing from degraded flex duct liner in 2010s-era builds. Our process isolates the affected duct runs, removes the source material when accessible, and treats remaining surfaces with oxidizing agents that break odor compounds at the molecular level, not masking agents that dissipate in days.

UV Light Installation
UV light installation places germicidal ultraviolet lamps at the evaporator coil or in the return plenum, where continuous exposure inhibits microbial growth on wet surfaces that are otherwise impossible to keep clean. We specify lamp intensity and placement based on your system’s CFM rating and coil dimensions, using fixtures from manufacturers like Honeywell and Abatement Technologies that publish independent kill-rate data for specific pathogens. In Austin’s extended cooling season, where systems run eight months annually, UV lamps require annual replacement to maintain output, and we include this maintenance schedule in your written scope so there are no surprise costs.

Air Purifier Install
Air purifier install refers to whole-house filtration or purification devices integrated at the air handler, not portable units that treat single rooms, including media filters with MERV 13-16 ratings, electronic precipitators, or photocatalytic oxidation systems. We size these based on your system’s static pressure tolerance, a measurement many Austin contractors ignore, and we specify Aprilaire and Guardsman equipment with documented pressure-drop curves so your blower motor is not overworked. Every installation quote includes the written price for the device, labor, and any necessary duct modifications, with no additional charges after agreement under Haven Standard Clause 1.

Allergen Reduction
Allergen reduction combines mechanical removal of accumulated particulate with source control for the specific triggers affecting occupants, whether cedar pollen in January, oak in March, or year-round dust mite debris in carpeted homes. In Austin’s allergy corridor, we regularly find that standard duct cleaning alone is insufficient; the fine particulate that causes symptoms has bonded to duct lining or penetrated fiberglass board, requiring agitation with Rotobrush contact cleaning followed by negative-pressure extraction. We document the particulate volume removed from each duct run in your photo record, so you can correlate the treatment with symptom changes rather than taking our word for it.

Brands We Service for Air Quality & Sanitizing

We install and service Honeywell whole-house media cleaners and UV germicidal systems, equipment we’ve specified in hundreds of Austin homes since 2013, with familiarity for their F100 and F300 series flow rates and the pressure-drop implications for variable-speed blowers common in 2018-2024 builds. Our crews also work extensively with Aprilaire, particularly their 5000-series electronic air cleaners and cabinet-style media filters, which we size to the return plenum dimensions rather than forcing a standard box into an irregular space. We’ve serviced Abatement Technologies portable and installed HEPA filtration in Austin homes during renovation and post-remediation, and we stock Guardsman antimicrobial treatments for duct surfaces where manufacturer specifications permit their application.
Whether you have Honeywell, Aprilaire, Abatement Technologies, Guardsman, or any other make of air quality equipment, we can evaluate its condition, clean or repair it, or recommend replacement when the device has exceeded its service life. We do not sell equipment we cannot document, and we do not install brands whose specifications we cannot verify independently. Bring us a competitor’s written estimate for any of these systems; under our Free Second Opinion policy, we’ll put our own number next to it in writing at no cost.
Before
AfterSigns You Need Air Quality & Sanitizing Right Now
- Persistent musty odor when the HVAC cycles on. This indicates active microbial growth, typically mold or bacteria, on wet surfaces inside the system. In Austin’s climate, we see this most often in homes where the evaporator coil has not been cleaned in three or more years, or where duct runs in unconditioned spaces have developed condensation from missing or degraded insulation.
- Allergy symptoms that worsen at home and improve when you leave. If your congestion, eye irritation, or respiratory symptoms peak within 30 minutes of arriving home and ease during your commute, your duct system is likely circulating concentrated allergen loads. We document the particulate burden in your specific duct runs so you can compare indoor and outdoor exposure quantitatively.
- Visible mold or discoloration around supply registers. Black, green, or gray spotting on ceiling or wall registers indicates that mold has colonized the duct interior and is releasing spores into conditioned air. This is not a surface cleaning job; the colony extends into the duct run, and disturbing it without containment spreads spores throughout the home.
- Recent water intrusion or flooding, even if “dried out.” Austin’s flash flooding and occasional pipe bursts in slab foundations create conditions where duct systems in crawl spaces or lower walls absorb moisture through contact or vapor drive. We inspect with borescope cameras to find growth in areas that appeared dry to the touch, and we treat or replace affected sections with written documentation for insurance purposes.
- Chronic HVAC filter clogging, faster than 30-day intervals. A filter that loads with debris in two weeks instead of two months signals that the duct system is circulating abnormal particulate loads, often from deteriorated duct lining, construction debris, or biological growth breaking loose from interior surfaces. We identify the source in your photo record rather than selling you better filters that mask the underlying problem.
Our Air Quality & Sanitizing Process - Step by Step

- 1
Written estimate with scope and price. We inspect your system with borescope cameras, identify the specific contaminants and affected duct runs, and deliver a written price before any work begins. This is Haven Standard Clause 1, not a courtesy. The scope names each duct run, the treatment for each, and the deliverables you’ll receive.
- 2
Containment and protection. We seal supply and return registers in untreated areas with magnetic covers, protect flooring and furnishings with drop cloths, and establish negative pressure at the work zone to prevent cross-contamination. Our technicians wear respirators and protective equipment appropriate to the contaminants identified, not universal paper masks.
- 3
Mechanical removal and contact cleaning. We agitate interior duct surfaces with Rotobrush contact cleaning systems or mechanical whips, depending on duct material and contamination type, while maintaining negative-pressure extraction with Nikro HEPA-collection equipment. Every duct run is photographed before this step begins.
- 4
Application of treatment agents. We apply EPA-registered antimicrobials, sanitizers, or odor neutralizers matched to the specific contaminants and surface materials in your system. Application methods vary: fogging for full duct runs, direct spray for coil and plenum surfaces, or foam application for targeted mold remediation. We record product names and concentrations in your job record.
- 5
Verification and documentation. We photograph every treated duct run after completion, measure airflow at key registers to confirm system balance, and deliver your complete photo record with the written scope, product data sheets, and the 365-Day Done Right Promise. If the work is not right, we make it right, backed in writing, not subject to manager approval.
How Much Does Air Quality & Sanitizing Cost in Austin?
A typical whole-home bacteria sanitizing and odor removal in Austin runs $350-$550 for a single-system home with 8-12 duct runs, while mold treatment requiring contained removal and antimicrobial application ranges $500-$850 depending on the number of affected runs and whether coil or plenum work is included. UV light installation with a Honeywell or Abatement Technologies fixture typically falls between $400-$700 including lamp, housing, electrical connection, and first-year replacement schedule. Whole-house air purifier installation, such as an Aprilaire media cleaner or electronic precipitator, ranges $600-$1,200 depending on cabinet size, duct modifications required, and whether your existing blower can handle the static pressure increase without upgrade.
Several factors move these ranges. Homes in Austin’s 2015-2022 construction boom, particularly in neighborhoods like Easton Park, Mueller, and Whisper Valley, often have complex multi-zone systems with more duct runs and tighter access, increasing labor time. Crawl-space and attic duct runs in older homes, common in Allandale, Brentwood, and Rosedale, may require additional containment setup if insulation is degraded or rodent activity is present. The severity of contamination affects product selection and dwell time; a light bacterial film requires less intensive treatment than established mold colonization with visible sporulation.
To avoid overpaying, reject any quote that does not specify the exact duct runs to be treated, the products to be used by name, and the documentation you’ll receive. The $79-$149 “whole house” specials common in Austin market mailers typically cover a single register cleaning with a shop vacuum and a spray of unlabeled solution, with upselling to follow once the technician is inside your home. Our price is the price, agreed in writing before work starts, with no per-vent add-ons or surprise charges for “heavy contamination” discovered mid-job. Call (737) 243-9544 for a written estimate at no cost; we’ll inspect with cameras, name the specific conditions in your system, and deliver a scope you can compare to any competitor’s quote under our Free Second Opinion policy.

Frequently Asked Questions - Air Quality & Sanitizing in Austin

Air quality and sanitizing targets living contaminants, mold, bacteria, viruses, and the odors they produce, while standard duct cleaning removes accumulated dust and debris. We perform sanitizing with EPA-registered agents applied after mechanical cleaning, and we document the specific contaminants found in your system with borescope photography so you can see the difference between particulate buildup and active microbial growth.
A typical whole-home sanitizing treatment takes 3-5 hours for a single-system home with 8-12 duct runs, while mold remediation or multi-zone systems may extend to a full day. We do not schedule by the hour; we schedule by the scope, and we do not leave until every duct run in your written estimate has been treated and documented.
Whole-home bacteria sanitizing and odor removal typically runs $350-$550, mold treatment $500-$850, UV light installation $400-$700, and whole-house air purifier installation $600-$1,200, all with written prices agreed before work begins. Call (737) 243-9544 for a written estimate specific to your system; estimates are free and include borescope inspection.
Yes, we install and service Honeywell, Aprilaire, Abatement Technologies, and Guardsman equipment, with documented familiarity for their specifications and pressure-drop characteristics. We do not install brands whose performance data we cannot verify independently, and we name the specific equipment in your written scope so you can research it before approving the work.
We do not classify air quality and sanitizing as emergency dispatch; it is a scheduled service requiring proper containment and treatment time. Most Austin core neighborhoods book within 3-5 business days. If you have active water intrusion or visible mold affecting occupied space, we can prioritize inspection and temporary containment while scheduling full treatment.
Every job is backed by our 365-Day Done Right Promise: if the work is not right, we make it right, in writing on every job, not as a policy subject to manager approval. This is separate from manufacturer warranties on installed equipment like UV lamps or air purifiers, which we document and explain in your job record.
Ensure access to all registers, the air handler, and any attic or crawl-space access points; remove fragile items from surfaces near work areas; and plan for pets and sensitive individuals to be out of the home during treatment and for two hours after, while applied agents reach their dwell time and ventilation clears residual product. We will confirm specific preparation needs, such as filter replacement or pre-cleaning, in your written scope before arrival.
