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 Houston Homeowners
Our Air Quality & Sanitizing in Houston typically addresses mold, bacteria, allergens, and persistent odors inside your ductwork and HVAC system, with whole-home treatments running $450-$1,200 depending on scope. In Houston’s Gulf Coast climate, where summer humidity stays above 75% for months and winter temperature swings force constant HVAC cycling, untreated duct systems become active reservoirs for microbial growth. We’ve documented this since 2013, serving over 52,000 homes across Harris, Fort Bend, and Montgomery counties with written prices delivered before any work starts and a photo record of every duct run delivered before our crew leaves.
CleanRun Air Duct Cleaning Houston operates under the H.A.V.E.N. Standard, with background-checked, uniformed technicians identified by name before arrival. Our equipment roster includes Rotobrush, Nikro, Abatement Technologies, Honeywell, Aprilaire, and Guardsman - trade-recognized brands you can verify independently. Every job is backed by our 365-Day Done Right Promise in writing. Call (346) 251-8919 for a free estimate with a written price, not a verbal guess.
What Our Air Quality & Sanitizing Service Includes
Mold Treatment
Mold treatment targets active fungal colonies inside duct runs, the plenum (the central distribution box where all ducts connect), and evaporator coils where Houston’s humidity condenses on cold surfaces. You need this when you smell mustiness near registers, see dark spotting around vent edges, or when a family member’s respiratory symptoms worsen seasonally despite outdoor pollen counts being low. At CleanRun Air Duct Cleaning Houston, we photograph every affected section with a borescope camera, apply EPA-registered antimicrobial agents through negative-pressure extraction systems to prevent cross-contamination, and deliver before-and-after images as part of your documented photo record. Haven Standard Clause 1 requires the written price before any panel comes off.

Bacteria Sanitizing
Bacteria sanitizing eliminates microbial loads that standard duct cleaning leaves behind, particularly in homes with pets, recent water intrusion, or immunocompromised residents. You need this when there’s a persistent “sick building” feeling, when occupants experience unexplained fatigue or throat irritation that improves away from home, or after any flooding event in Houston’s flash-flood-prone neighborhoods like Meyerland or Braeswood. Our technicians use professional-grade fogging equipment from Abatement Technologies to distribute sanitizing agents throughout the entire duct network, not just reachable trunk lines, with application verified by post-treatment swab documentation on request.

Odor Removal
Odor removal addresses volatile organic compounds and residual smells from tobacco, cooking oils, pet accidents, or previous owner’s habits that have adsorbed into duct lining and become re-entrained with every HVAC cycle. You need this when standard cleaning and filter changes fail to eliminate smells, when odors intensify when the system first kicks on, or when you’re preparing a Houston home for sale and need neutral interior air for showings. CleanRun treats the source material inside the ductwork with oxidizing agents and activated carbon filtration, then verifies results with the customer present - we don’t declare the job done until you confirm the smell is gone.

UV Light Installation
UV light installation places germicidal ultraviolet lamps at the evaporator coil and plenum, the two locations where microbial growth is most persistent in Houston’s climate. You need this when mold or bacteria recur within 12 months of treatment, when your system runs continuously during summer months creating ideal breeding conditions, or when a household member has asthma or COPD requiring proactive prevention. We size and install Honeywell and Aprilaire UV systems matched to your air handler’s dimensions, with lamp replacement intervals and costs disclosed in writing before installation. The 365-Day Done Right Promise covers both the hardware and the installation workmanship.

Air Purifier Install
Air purifier installation adds whole-home filtration at the HVAC return, treating every cubic foot of circulated air rather than relying on portable units that only clean single rooms. You need this when particle counts remain elevated after duct cleaning, when someone in the home has severe allergies or autoimmune conditions, or when you’re in a Houston corridor with construction dust, highway particulate, or seasonal wildfire smoke drift. CleanRun specifies MERV ratings, pressure-drop implications for your blower motor, and filter replacement costs in the written scope - we don’t sell equipment that strains your existing system or hides ongoing costs.

Allergen Reduction
Allergen reduction combines mechanical filtration, duct sealing to prevent attic and crawl space infiltration, and targeted treatment of reservoirs where pollen, dust mite debris, and pet dander accumulate. You need this when allergy symptoms persist indoors during Houston’s year-round pollen seasons, when children’s eczema or asthma flares correlate with HVAC use, or after purchasing a home with unknown prior pet or smoking history. We identify leakage points with a smoke pencil, seal accessible ductwork with mastic, and document particle count reduction with pre- and post-treatment measurements where requested.

Brands We Service for Air Quality & Sanitizing

We’ve installed and serviced hundreds of Honeywell whole-home air purifiers and UV systems across Houston, from 1960s ranch homes in Memorial to new construction in Bridgeland, plus our Air Quality & Sanitizing in Bellaire. Their F100 and F300 electronic air cleaners require specific pressure-drop calculations we perform before quoting, and we stock replacement cells and pre-filters so customers aren’t left sourcing parts independently.
Aprilaire humidifiers, dehumidifiers, and ventilation controllers are standard equipment in many Houston-area homes built 2015-2025, and we’ve diagnosed installation errors - like bypass ducts routed through unconditioned attic space - that actually worsen indoor air quality. We’ve also serviced Rotobrush and Nikro negative-pressure extraction equipment on hundreds of jobs, so we understand from the technician’s side what thorough duct cleaning actually requires. Whether you have Honeywell, Aprilaire, or any other make, we can evaluate your system and specify what’s needed without generic recommendations.
Before
AfterSigns You Need Air Quality & Sanitizing Right Now
- Musty or chemical smells when the HVAC cycles on. Odors that intensify at system startup indicate microbial growth or volatile residue inside ductwork, not just a dirty filter. In Houston’s humidity, we’ve photographed active mold on evaporator coils in homes less than three years old where the builder-grade installation lacked adequate drainage slope.
- Respiratory symptoms that improve when you leave home. If congestion, coughing, or headaches ease within hours of being away and return within hours of return, your duct system is the likely source. We’ve documented this pattern particularly in Bellaire and Jersey Village homes with encapsulated crawl spaces where duct leakage draws in soil gases and moisture.
- Visible mold or discoloration around registers or in the return grille. Surface spotting at vents often indicates much more extensive colonization upstream where you can’t see without a camera. We treat the visible symptom and the hidden source, with photo documentation of both.
- Persistent dust accumulation despite frequent filter changes. If you’re replacing MERV 8 filters monthly and still wiping thick dust weekly, your ducts are either leaking unfiltered attic air or harboring debris reservoirs that bypass filtration. Our smoke-pencil testing locates the exact leakage points.
- Recent water damage or flooding in your Houston home. Even “minor” leaks from Hurricane Harvey recovery, slab foundation shifts common in the gumbo clay soils of Katy and Sugar Land, or condensation line backups create conditions for bacterial and mold growth that standard cleaning won’t address. We assess with moisture meters and thermal imaging before quoting any treatment scope.
Our Air Quality & Sanitizing Process - Step by Step

- 1
Written estimate with scope and price. We inspect your accessible ductwork, HVAC components, and discuss your specific concerns. Haven Standard Clause 1 requires the written price before any work begins - you’ll receive a single flat price for the complete system, not per-vent add-ons that inflate on arrival.
- 2
Photo documentation of current conditions. Our technician inserts a borescope camera into every duct run, photographing debris, mold, or damage before touching anything. These images become your baseline record, delivered with your final job documentation.
- 3
Containment and negative-pressure setup. We seal registers and establish negative-pressure extraction using Nikro or Rotobrush HEPA-filtered collection systems. This prevents contamination of your living space during treatment, a step coupon operators often skip.
- 4
Targeted treatment application. Based on findings, we apply antimicrobial agents, install UV or filtration equipment, or seal duct leakage with mastic. Every product and technique is named in your written scope, with Safety Data Sheets available on request.
- 5
Post-treatment verification and photo record delivery. We re-photograph every treated duct run, test system operation, and review results with you present. Your documented photo record, written scope, and 365-Day Done Right Promise are delivered before payment is processed.
How Much Does Air Quality & Sanitizing Cost in Houston?
Air Quality & Sanitizing pricing for a typical bacteria sanitizing or odor removal treatment for a single HVAC system in Houston runs $450-$750. Whole-home mold treatment with full duct access, coil cleaning, and antimicrobial application typically ranges $800-$1,200. UV light installation with a Honeywell or Aprilaire system sized to your air handler runs $650-$1,100 including hardware and labor. Air purifier installation at the return duct, with MERV 13+ filtration and pressure-drop verification, generally falls between $900-$1,500 depending on existing duct configuration.
Several factors move prices within these ranges. System accessibility matters: ducts in a finished attic or behind drywall in a two-story Houston townhome require more labor than open basement or garage installations common in older Spring Branch homes. The extent of contamination affects chemical and time requirements - a light musty smell in a 1,500-square-foot Heights bungalow takes less than active mold in a 4,000-square-foot home in The Woodlands with multiple zones. Additional HVAC systems, common in homes with guest quarters or pool houses in River Oaks or Tanglewood, are priced separately with multi-system discounts disclosed in writing.
To avoid overpaying, reject any quote that won’t put the full price in writing before work starts, or that quotes a low per-vent rate that multiplies once the truck arrives. CleanRun’s Haven Standard Clause 1 prohibits this practice. Our free estimate includes a written scope, flat price, and explanation of what’s included - no “call for quote” ambiguity. Bring a competitor’s written estimate and we’ll provide a free second opinion with our number beside it.

Frequently Asked Questions - Air Quality & Sanitizing in Houston

Air quality and sanitizing targets living contaminants - mold, bacteria, viruses, and odor-causing compounds - that mechanical duct cleaning removes but doesn’t kill. Standard duct cleaning with negative-pressure extraction clears debris and dust; sanitizing applies EPA-registered antimicrobial agents, UV light, or advanced filtration to address the biological load that persists in Houston’s humid climate. We perform both services and specify in your written estimate which your system actually needs based on borescope inspection findings.
A typical whole-home bacteria sanitizing or odor removal takes 3-5 hours; mold treatment with full duct access and coil cleaning runs 5-8 hours; UV light or air purifier installation requires 2-4 hours. We specify the expected duration in your written scope so you can plan your day - no open-ended “we’ll be done when we’re done” scheduling. Call (346) 251-8919 for an exact quote and time estimate tailored to your home’s system.
Most Houston homeowners pay $450-$1,200 for complete air quality and sanitizing service, with the specific price depending on system size, contamination extent, and whether equipment installation is included. We publish these ranges because Haven Standard Clause 1 requires written upfront pricing - the exact figure for your home comes after inspection, never after work begins. Call (346) 251-8919 for a free estimate with a written price you can compare.
Yes. We’ve installed and serviced hundreds of Honeywell and Aprilaire whole-home air purifiers, UV systems, and ventilation controls across Houston, and we stock replacement filters, UV lamps, and electronic cells for common models. We name the specific parts your system needs in the written scope, with costs disclosed before ordering. If you have another brand, we evaluate compatibility and specify alternatives in writing.
We schedule urgent cases within 24-48 hours when health concerns are documented, such as immunocompromised residents or active mold exposure affecting breathing. We do not claim 24/7 dispatch for scheduled maintenance work because air quality treatment requires proper setup time and isn’t improved by rushed execution. All calls are answered by a live person who can assess urgency and schedule appropriately.
Every job is backed by our 365-Day Done Right Promise: if the work is not right, we make it right, documented in writing on every invoice. Haven Standard Clause 5 requires this guarantee without manager approval gates or claim denial loopholes. For UV and air purifier installations, manufacturer warranties apply to hardware and are detailed in your written scope.
Clear a 3-foot workspace around your indoor HVAC unit and main return grille; secure pets in a separate room during treatment; and have your current filter brand and size available if you’d like us to assess its adequacy. We don’t require furniture moving or special ventilation - our negative-pressure containment handles that. We’ll confirm any home-specific needs when scheduling. Call (346) 251-8919 to book your free estimate.
