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 The Woodlands Homeowners
Air quality and sanitizing service in The Woodlands typically addresses mold, bacteria, allergens, and odors inside your HVAC system and ductwork, with whole-home treatments running $450-$1,200 depending on scope. CleanRun Duct Repair & Cleaning has documented the inside of every duct run we’ve touched since 2013, and we bring that same practice to air quality work in The Woodlands, Tomball, and Conroe. Call (346) 248-1474 for a written price before any work starts.
The Woodlands sits on a humid subtropical pocket where summer dew points regularly push past 70 degrees and winter temperature swings force HVAC systems through constant expansion cycles. That moisture collects in ductwork, especially in two-story homes built during the 2015-2020 construction boom in neighborhoods like Creekside Park, Sterling Ridge, and Panther Creek. We’ve pulled photo records showing microbial growth on fiberglass duct board less than four years after installation, and we’ve found bacterial loading in condensate pans that homeowners had no visible indication of until we showed them the image.
CleanRun was established in 2013. We’ve served more than 52,000 homes. Every job starts with a written price delivered before a single panel comes off, and every job ends with a Documented Photo Record of every duct run, included as standard. The 365-Day Done Right Promise applies to air quality work the same as it applies to duct cleaning: if it’s not right, we make it right, backed in writing on every job. Our technicians are 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 active fungal growth inside ductwork, plenums (the main distribution box connected to your air handler), and evaporator coils. In The Woodlands, we regularly find Cladosporium and Aspergillus species colonizing fiberglass duct board in homes near the George Mitchell Nature Preserve, where tree canopy shade keeps crawl spaces and attic ducts cooler and wetter for longer periods. CleanRun applies EPA-registered fungistatic treatments after mechanical agitation with Rotobrush contact vacuuming, then documents the treated surfaces with before-and-after photography. We do not paint over mold or rely on fogging alone, which leaves dead hyphae in place as future food sources.
Bacteria Sanitizing
Bacteria sanitizing addresses microbial loading from pet dander accumulation, water intrusion events, or biofilm formation in condensate drainage systems. The camera often shows a slimy film on coil fins that homeowners mistake for ordinary dust. CleanRun uses negative-pressure extraction (suction that pulls contaminants out of the system rather than redistributing them) combined with professional-grade sanitizers applied at manufacturer-specified dwell times. We name the product on your written scope, note its EPA registration number, and photograph the application. In homes near Lake Woodlands or along the Buffalo Bayou tributaries, where water tables sit higher, we see this need more frequently and adjust our protocol accordingly.
Odor Removal
Odor removal eliminates persistent smells that originate inside the HVAC system rather than in the conditioned space itself. The source is often a dead rodent in a duct run, pet urine that wicked into fiberglass insulation, or volatile organic compounds off-gassing from microbial metabolism. CleanRun locates the source with borescope inspection (a flexible camera fed into the ductwork), removes the contaminated material when accessible, and treats remaining surfaces with oxidizing agents that break odor molecules rather than masking them. We do not promise “fresh linen” scent; we promise the absence of the original smell, verified by follow-up inspection if requested under the 365-Day Done Right Promise.
UV Light Installation
UV light installation places ultraviolet-C lamps at the evaporator coil and sometimes at return air entries to inhibit microbial growth on wet surfaces. The Woodlands’ cooling season runs from late March through October, meaning coils stay wet for seven-plus months. CleanRun sizes UV output to the coil dimensions and airflow velocity, using lamps from manufacturers like Abatement Technologies that publish dosage specifications in microwatts per square centimeter. We document the initial lamp intensity reading with a UV meter, note the replacement interval on your written record, and photograph the mounting location so future technicians know what was installed.
Air Purifier Install
Air purifier install refers to whole-house filtration or electronic air cleaning devices mounted at the air handler or in return ductwork, not portable room units. CleanRun has installed Honeywell and Aprilaire media filters, as well as Abatement Technologies HEPA bypass systems, in The Woodlands homes ranging from 1,800-square-foot patio homes in Grogan’s Mill to 6,000-plus-square-foot properties in Carlton Woods. We size the pressure drop across the filter to your system’s blower capacity, because an undersized blower with a restrictive filter fails in two ways: poor airflow and premature motor failure. The written scope includes the measured static pressure before and after installation.
Allergen Reduction
Allergen reduction combines mechanical removal of accumulated particulate with source control for ongoing relief. The Woodlands ranks high in Texas for tree pollen counts, and we’ve found pine pollen accumulated in duct runs two years after the season it was drawn in, because standard fiberglass filters don’t capture particles below 10 microns efficiently. CleanRun’s process includes contact vacuuming with Rotobrush agitation, followed by assessment of whether the home’s filtration upgrade path should include MERV 13 pleated media or a dedicated HEPA bypass. We photograph the filter slot and note any gaps that allow bypass airflow, because a high-efficiency filter with a 1/2-inch gap around the perimeter performs like a low-efficiency one.

Brands We Service for Air Quality & Sanitizing
CleanRun’s equipment roster includes Abatement Technologies portable HEPA filtration units and UV-C systems we’ve installed in more than 400 The Woodlands homes since 2016. Their PREDATOR series negative air machines are standard on our mold remediation setups, and we maintain calibration records on every unit. We’ve also deployed Guardsman antimicrobial treatments in dozens of bacterial sanitizing jobs, particularly in homes with recent water damage from Hurricane Harvey-related roof leaks that weren’t fully resolved until mold had established. Customers can verify Abatement Technologies’ and Guardsman’s specifications independently; we name the exact model or product on every written scope.
Rotobrush brush-and-vac systems and Nikro HEPA vacuums handle the mechanical agitation and extraction phases of our allergen reduction and mold treatment protocols. Whether you have an existing Honeywell electronic air cleaner, an Aprilaire whole-house humidifier that needs sanitizing, or any other make of equipment, we can assess its condition, document what we find, and recommend specific next steps with a written price before any work starts.
BeforeAfterSigns You Need Air Quality & Sanitizing Right Now
- Musty or sour smell when the HVAC cycles on. This indicates microbial growth in the plenum, coil, or ductwork that becomes aerosolized when air moves across it. The smell often fades after a few minutes as your nose adapts, but the source remains active and distributing spores or bacterial fragments into living spaces.
- Visible mold near supply registers or return grilles. What you can see on the surface often represents a fraction of the total colonization. In The Woodlands’ high-humidity climate, we’ve found duct interiors with ten times the visible surface growth, especially at joints where fiberglass tape has degraded and created a porous food source.
- Increasing allergy or asthma symptoms that correlate with time spent at home. If symptoms improve when you leave for work and worsen within an hour of returning, your HVAC system is likely the dominant exposure pathway. We see this pattern frequently in newer The Woodlands construction with tight building envelopes that limit dilution ventilation.
- Recent water damage or plumbing leak, even if “dried out.” Fiberglass duct insulation wicks water horizontally and can remain damp for weeks after surface materials appear dry. We’ve documented active mold growth in ductwork above ceilings where the homeowner was told the leak was “handled” months earlier.
- Persistent odors after professional carpet cleaning or painting. When surface treatments don’t resolve a smell, the source is often in the HVAC system, which redistributes air from hidden reservoirs. CleanRun’s borescope inspection can locate these sources without destructive investigation.
Our Air Quality & Sanitizing Process - Step by Step
- 1
Written estimate delivered on site. Our technician inspects accessible ductwork, the air handler, and filtration components with a borescope where needed. We describe what the camera showed, specify the treatment protocol, and deliver a written price under Haven Standard Clause 1. No work begins until you have that document.
- 2
Containment and negative pressure setup. For mold treatment and bacteria sanitizing, we isolate the work zone with polyethylene sheeting and run Abatement Technologies HEPA filtration to create negative pressure. This prevents cross-contamination to unaffected areas of your home during agitation and removal phases.
- 3
Mechanical agitation and extraction. We use Rotobrush contact vacuuming in duct runs, hand cleaning for plenums and coils, and Nikro HEPA vacuums for debris removal. Each duct run is photographed before and after. The photo record becomes part of your permanent job file.
- 4
Treatment application with documented dwell time. Sanitizers, fungistats, or oxidizers are applied at manufacturer-specified concentrations and contact times. We note the product name, EPA registration number, and application time on your written scope. UV lamps or air purifiers are installed with measured intensity or pressure-drop readings documented.
- 5
Final inspection, photo record delivery, and written warranty. The technician reviews every after-treatment photo with you, explains what was done and why, and leaves you with the written scope, the photo record, and the 365-Day Done Right Promise. Payment is collected only after this review is complete.
How Much Does Air Quality & Sanitizing Cost in The Woodlands?
A typical Air Quality & Sanitizing pricing for bacteria sanitizing or odor removal in The Woodlands runs $450-$750 for a single-system home up to 3,500 square feet. Mold treatment starts at $800 and ranges to $2,400 depending on the number of duct runs affected, whether duct board needs replacement rather than surface treatment, and whether the evaporator coil requires removal for cleaning. UV light installation runs $380-$650 per lamp location, including the fixture, bulb, and measured intensity documentation. Whole-house air purifier installation ranges from $520 for a high-MERV media upgrade to $1,800-$2,800 for a HEPA bypass system with dedicated blower.
Several factors move the price within these ranges. Homes in Creekside Park and Sterling Ridge built 2016-2020 often have extended duct runs with multiple elbows that increase labor time. Attic ductwork in summer adds temperature-related work restrictions that extend job duration. The presence of flex duct with internal insulation, common in production builds throughout The Woodlands, sometimes requires section replacement rather than cleaning when the inner liner is compromised.
To avoid overpaying, reject any quote that doesn’t specify the exact treatment protocol in writing. The $79 duct cleaning coupon model often leads to upsold “sanitizing” fogging at $400-$600 that leaves debris in place and provides no photo documentation. CleanRun’s price includes the mechanical work, the treatment, and the photo record as standard. We also offer a Free Second Opinion on any written estimate from another company; bring their scope and we’ll put our number next to it in writing.
Every estimate is free and carries no obligation. The technician who arrives is the technician who does the work, not a closer sent to secure a signature.

Frequently Asked Questions - Air Quality & Sanitizing in The Woodlands
Air quality and sanitizing targets living or chemical contaminants (mold, bacteria, odors, allergens) with treatments that kill, remove, or neutralize them, while duct cleaning removes accumulated dust and debris through mechanical agitation and extraction. Duct cleaning may leave active microbial colonies in place; sanitizing addresses the biological or chemical source directly. CleanRun often performs both services in sequence, with the cleaning phase first and treatment second, documented in separate photo sets.
A typical bacteria sanitizing or odor removal in a 2,500-square-foot The Woodlands home takes three to four hours, similar to Air Quality & Sanitizing in Spring; mold treatment with containment setup runs five to eight hours; UV light or air purifier installation adds one to two hours per device. We schedule specific arrival windows, not all-day windows, and we don’t leave until the photo record is complete and you’ve reviewed it. Call (346) 248-1474 for an exact time estimate based on your system layout.
Most homeowners in The Woodlands pay $450-$1,200 for air quality and sanitizing services, with bacteria and odor work at the lower end, mold treatment in the middle, and whole-house air purifier installations at the upper end; see our Air Quality & Sanitizing in Pinehurst for nearby pricing context. The specific price depends on system size, contamination extent, and whether duct material needs replacement. CleanRun delivers a written price before any work starts, with no per-vent add-ons or post-arrival upsells. Call (346) 248-1474 for a free estimate.
Yes. CleanRun installs and services Honeywell electronic air cleaners, Aprilaire whole-house media filters and humidifiers, and Abatement Technologies HEPA and UV systems. We name the specific model on your written scope, verify compatibility with your existing blower capacity, and document pressure-drop or intensity readings after installation. If you have another brand, we assess it the same way and recommend only what the system can support.
Active mold growth and sewage-related bacterial contamination should be addressed promptly to prevent spread, but most air quality concerns are scheduled services rather than emergencies. CleanRun does not charge emergency rates or after-hours premiums; we schedule during regular hours and complete the work with the same documentation protocol regardless of urgency. If you’re unsure whether your situation needs immediate attention, call (346) 248-1474 and we’ll advise based on what you describe.
Every job is backed by the 365-Day Done Right Promise: if the work is not right, CleanRun makes it right, with no manager approval required to honor the commitment. The promise is written on every scope, not stated only in marketing materials. For mold treatment, we also specify the conditions that maintain the result, such as humidity control and filter maintenance, so you understand what preserves the work.
Clear a three-foot workspace around the air handler and at least one supply register per room; secure pets in a separate area; and have your current filter available for inspection. You don’t need to clean or vacuum beforehand; we document the system as found. The technician will need access to the attic or crawl space if ductwork runs through those areas, which is common in The Woodlands homes built on pier-and-beam or with attic-mounted air handlers.
