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 Lewisville Homeowners
Lewisville Air Quality & Sanitizing service typically addresses mold, bacteria, allergens, and persistent odors inside your HVAC system, with whole-system treatments running $450-$1,200 depending on scope and home size. CleanRun Air Duct Cleaning Lewisville has delivered documented photo records of every duct run since 2013, and we put a written price on paper before any panel comes off your system. Call (940) 240-8552 for a free estimate with no obligation.
We’ve treated air quality issues in more than 52,000 homes, and the pattern we see in Lewisville is specific. The clay-heavy soils in Denton County shift with seasonal moisture, which cracks duct seals and lets attic air, rodent droppings, and pollen load into the plenum, the main distribution box where all your duct runs connect. Older neighborhoods near Old Town Lewisville and the Valley Ridge corridor have galvanized ductwork from the 1980s and 1990s that corrodes at the seams, creating pockets where condensation collects and microbial growth takes hold. Newer construction in Castle Hills and The Colony adjacent areas often has tight building envelopes with undersized ventilation, so pollutants recirculate rather than exhaust. We don’t guess at what’s happening inside your system. We run a camera through every duct run, the individual supply and return lines feeding each room, and show you the image before we write the scope.
What Our Air Quality & Sanitizing Service Includes
Mold Treatment
Mold treatment targets visible and hidden fungal growth inside the duct run, the plenum, and the evaporator coil housing, where dark, damp conditions allow colonies to establish. In Lewisville, we most often find mold at the first elbow downstream of the air handler, where temperature differential creates condensation on galvanized steel during our humid spring months. CleanRun treats affected areas with an EPA-registered antimicrobial applied through a fogging system after negative-pressure extraction, the process of sealing the ductwork and using suction to contain debris, removes loose particulate. We photograph every treated surface before and after, and the photo record is delivered with your job documentation.
Bacteria Sanitizing
Bacteria sanitizing addresses microbial contamination that doesn’t present as visible mold but produces musty odors and can aggravate respiratory conditions. This service matters most in Lewisville homes with pets, recent water intrusion, or systems that sat idle through a hot summer with standing water in the drain pan. Our crew applies a hospital-grade sanitizer through the entire duct network using a Rotobrush pneumatic delivery system, which propels the agent past the register, the visible vent cover, and into the full length of each duct run. The product we use breaks down to water and oxygen; we document the application points and dwell time in your written job record.
Odor Removal
Odor removal eliminates persistent smells that originate inside the HVAC system rather than in the living space, where candles and sprays merely mask the source. We trace odors using a borescope camera inspection of the plenum and trunk lines, identifying dead rodents, pet dander accumulation, or decomposed organic material caught in low-velocity sections of the ductwork. In Lewisville homes near Lewisville Lake, we’ve found that seasonal humidity spikes can reactivate old odor sources that seemed dormant through winter. Our process includes source removal, antimicrobial treatment of contaminated surfaces, and optional carbon filtration at the air handler to capture residual particulate.
UV Light Installation
UV light installation places a germicidal lamp at the evaporator coil or in the supply plenum, where it irradiates passing air and inhibits microbial growth on wet surfaces. This is a preventive measure, not a cleaning substitute, and it works best in Lewisville homes where the air handler runs continuously during our long cooling season. We size the lamp to your system CFM, cubic feet per minute of airflow, and specify replacement intervals in writing. CleanRun installs Honeywell and Aprilaire UV systems with published lamp intensity ratings, and we record the installation location and bulb serial number in your documented photo record for warranty tracking.
Air Purifier Install
Air purifier install refers to whole-house filtration units mounted at the air handler or in the return plenum, treating all air before it distributes through the duct runs. Unlike portable units that clean one room, these systems capture particles at the central point, which matters in Lewisville’s pollen-heavy spring when cottonwood and oak load the outdoor intake. We size purifiers to your system’s static pressure capacity, the resistance the blower can overcome without strain, and we favor Honeywell and Aprilaire units with MERV ratings and published pressure-drop data. Every install includes a written performance specification and before-and-after pressure readings.
Allergen Reduction
Allergen reduction combines mechanical cleaning with targeted filtration to lower pollen, dust mite debris, pet dander, and cockroach allergen levels in circulating air. Lewisville’s position at the edge of the Blackland Prairie means high grass pollen counts from March through June, and older homes in the Central Lewisville and Lakeland areas often have decades of accumulated allergen embedded in duct insulation. Our process uses HEPA-filtered negative-pressure extraction through the Nikro portable collection system, followed by sealant application at damaged duct joints to prevent recontamination from attic or crawl space air. We measure and photograph the filter loading to document the volume removed.

Brands We Service for Air Quality & Sanitizing
CleanRun Air Duct Cleaning Lewisville works with the equipment already in your home and installs new components from manufacturers whose specifications are publicly verifiable. We’ve serviced and installed Honeywell whole-house air purifiers and UV systems in hundreds of Lewisville-area homes, and we stock replacement lamps and filters with published MERV ratings so you’re not waiting on shipped parts. Our crews are familiar with the pressure-drop curves on Honeywell’s F100 and F200 media air cleaners, and we verify that your blower can handle the added resistance before recommending an upgrade.
We also install and maintain Aprilaire dehumidifiers and air purifiers, including the Model 5000 electronic air cleaner, which we often pair with UV in Lewisville’s tighter new construction where humidity control and particulate removal compete for equipment space. Whether your system carries Honeywell, Aprilaire, or any other make, we can inspect it, treat it, and document what we found. If you’re comparing options in neighboring communities, our Air Quality & Sanitizing in Carrollton page outlines the same process with local pricing context for that market.
BeforeAfterSigns You Need Air Quality & Sanitizing Right Now
- Persistent musty or sour odors when the HVAC cycles on. Odors that intensify when the blower starts indicate microbial growth inside the plenum or duct runs, not in the living space. In Lewisville’s humid climate, we see this most often in systems with clogged condensate drains or cracked plenum seams that draw attic air.
- Visible mold around registers or on the evaporator coil access panel. What you can see at the register, the vent cover in your ceiling or wall, usually indicates more extensive growth upstream where light doesn’t reach. We photograph the full length of each duct run to determine whether surface treatment or full remediation is warranted.
- Increased allergy or asthma symptoms that worsen at home and improve away. If your symptoms spike within an hour of returning to your Lewisville home, the HVAC system is likely circulating concentrated allergen loads. Our camera inspection identifies whether the source is duct contamination, filter bypass, or infiltration from an unsealed return.
- Recent water damage or roof leak, even if “dried out.” Duct insulation wicks moisture and holds it against metal surfaces for weeks. We’ve found active mold in Lewisville homes where the roof was repaired six months prior but no one inspected the ductwork above the leak path.
- Unexplained respiratory illness in household members or pets. Bacterial contamination, including Legionella in poorly maintained evaporator pans, can cause symptoms that mimic cold or flu. Sanitizing the system eliminates this vector, and we document the treatment agent and coverage area in your job record.
Our Air Quality & Sanitizing Process - Step by Step
- 1
Written estimate before any work begins. We inspect your system with a borescope camera, identify contamination type and extent, and deliver a written price under Haven Standard Clause 1. No verbal quotes, no range estimates that balloon, no work until you approve the number in writing.
- 2
Negative-pressure containment setup. We seal the duct system and connect a Nikro HEPA-filtered collection unit to create suction that prevents debris migration into your living space during cleaning. This is standard on every job, not an upgrade.
- 3
Mechanical agitation and extraction. The Rotobrush system drives a rotating brush through each duct run, dislodging adhered material while simultaneous vacuum capture pulls it into the collection unit. We vary brush diameter to match duct size, from 4-inch flexible returns to 12-inch rigid trunk lines.
- 4
Targeted sanitizing or treatment application. Based on what the camera showed, we apply antimicrobial, bactericide, or odor neutralizer through a pneumatic fogger that reaches past the register and coats the full duct surface. Dwell time and coverage area are recorded in your job documentation.
- 5
Documented photo record delivery and final verification. We photograph every treated duct run after completion, compile before-and-after images with the written scope and product specifications, and deliver the record as a standard job deliverable. Haven Standard Clause 5 requires this documentation on every visit.
How Much Does Air Quality & Sanitizing Cost in Lewisville?
Typical Air Quality & Sanitizing pricing in Lewisville for whole-system sanitizing runs $450-$750 for homes under 2,500 square feet with standard duct configurations. Mold treatment where visible growth is limited to the plenum and first few duct runs typically falls in the $650-$950 range. UV light installation with a Honeywell or Aprilaire unit sized to your system runs $400-$700 including lamp and mounting hardware. Whole-house air purifier install at the air handler ranges from $800-$1,200 depending on MERV rating and whether electrical work is needed. These are whole-system prices, not per-vent teaser rates that triple once the truck arrives.
Several factors move the price within these ranges. Duct accessibility matters: homes with attic air handlers and flex duct in tight crawl spaces take longer to access and photograph. The extent of contamination affects labor and material volume; a system with mold at every register requires more treatment agent and longer dwell time than spot contamination. Additional components like evaporator coil pull-and-clean, which we recommend when the coil shows debris loading, add $150-$250. We specify every line item in writing before work starts, and our home page outlines the full Haven Standard pricing structure.
To avoid overpaying, reject any quote that won’t commit to a firm number in writing, and be wary of per-vent pricing that obscures the total. CleanRun’s Free Second Opinion on Any Written Estimate means you can bring us a competitor’s quote and we’ll put our number beside it, line by line, with no obligation. Our price includes the documented photo record, the written warranty, and the 365-Day Done Right Promise, not as add-ons but as standard deliverables.

Frequently Asked Questions - Air Quality & Sanitizing in Lewisville
Air quality and sanitizing targets living or chemical contaminants, mold, bacteria, viruses, odors, that standard duct cleaning, which removes loose dust and debris, doesn’t eliminate. Duct cleaning uses mechanical brushes and vacuum extraction; sanitizing adds EPA-registered antimicrobial agents, UV light, or whole-house filtration to address the biological and chemical sources of poor air quality. If your concern is visible mold, persistent odor, or health symptoms, sanitizing is the appropriate service, and we determine the right scope through camera inspection.
A typical residential sanitizing job in Lewisville takes three to five hours for homes under 3,000 square feet, with mold treatment or UV install adding one to two hours. We don’t rush the dwell time for antimicrobial agents; the product we use requires 15 minutes of wet contact to achieve its rated kill log, and we document that interval in your job record. You’ll receive a time estimate with your written price before we start, and we don’t charge extra if the job runs longer than projected.
For our Air Quality & Sanitizing in Carrollton and Lewisville, whole-system sanitizing runs $450-$750, mold treatment $650-$950, UV light install $400-$700, and whole-house air purifier install $800-$1,200, with final price determined by home size, duct accessibility, and contamination extent. Every quote is a written, firm number delivered before work begins under Haven Standard Clause 1, not a range that shifts once we’re on site. Call (940) 240-8552 for an exact quote; estimates are free and carry no obligation.
Yes. We install, maintain, and repair Honeywell and Aprilaire whole-house air purifiers, UV systems, and dehumidifiers, and we stock replacement filters and lamps with published specifications. Our crews carry the pressure-drop charts for common models and verify system compatibility before recommending an upgrade. If you have another brand, we inspect and advise; if we can’t service it, we’ll tell you before charging a diagnostic fee.
We don’t use the term “emergency” to create false urgency, but we do prioritize active mold contamination, sewage backup in ductwork, and situations where a household member has severe respiratory compromise. All calls are answered by a live person, and we’ll schedule the earliest available appointment, often within 24-48 hours for priority cases. For standard sanitizing, three to five business days is typical.
Every job is backed by the 365-Day Done Right Promise: if the work is not right, we make it right, documented in writing on every invoice, not as a policy subject to manager approval. Mold treatment carries a one-year guarantee against recurrence at treated surfaces when the underlying moisture source is addressed. UV lamps and air purifier components carry the manufacturer’s warranty, and we register your installation for coverage and record the serial numbers in your job documentation.
Clear a three-foot workspace around the air handler and each register, and secure pets in a separate room during treatment. You don’t need to leave the home, though we recommend vacating for two hours after fogging application to allow dwell time and ventilation. We’ll tell you specifically which products we’re using and their re-entry intervals before we start, and we document the application in your written job record.
