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 Dallas Homeowners
Air Quality & Sanitizing - Dallas addresses mold, bacteria, odors, and airborne contaminants inside your HVAC system and living spaces. Most whole-home treatments run $350-$850 depending on the scope, and every job starts with a written price before any work begins. Call (469) 405-6133 for a free estimate with no obligation to proceed.
We’ve been serving Dallas homeowners since 2013, and in that time we’ve documented the inside of more than 52,000 duct systems. The photo records tell a consistent story: North Texas heat and humidity create conditions inside ductwork that standard cleaning alone doesn’t resolve. Mold colonies behind the plenum (the main distribution box connected to your air handler), bacterial biofilm on evaporator coils, and residual odors from previous water intrusion are common findings in homes built during the 2015-2025 construction boom across neighborhoods like Preston Hollow, Lakewood, and Bishop Arts.
Our crews operate under the H.A.V.E.N. Standard, with Haven Standard Clause 1 requiring a written price before any panel comes off your system. Tomas Reyes established this protocol when CleanRun began, and it hasn’t changed. You’ll receive a Documented Photo Record of every duct run, before and after, as a standard deliverable on every visit. No coupons, no per-vent pricing, no invoice that exceeds the written scope.
What Our Air Quality & Sanitizing Service Includes
Mold Treatment
Mold treatment targets active fungal growth inside duct runs, the plenum, and on HVAC components where moisture accumulates. In Dallas, we regularly find Cladosporium and Aspergillus species at the first elbow downstream of the evaporator coil, where condensation and 100°F summer attic temperatures create ideal conditions. Our process begins with a visual inspection using a borescope camera, followed by mechanical removal of visible growth, then application of an EPA-registered fungistatic treatment to affected surfaces. We photograph each stage and include these images in your job record so you can verify the treatment area and results.
Bacteria Sanitizing
Bacteria sanitizing addresses microbial contamination that produces odors and can aggravate respiratory conditions, particularly after water damage or in homes with pets. The process applies a commercial-grade sanitizer through the duct system using a fogging or coating method, depending on the contamination level and duct material. We use equipment from Nikro and Abatement Technologies, with application rates calculated by square footage of duct surface, not by guesswork. Every bacteria sanitizing job in Dallas includes pre- and post-treatment swab documentation upon request, so you have evidence of reduction, not just a receipt for service.
Odor Removal
Odor removal eliminates persistent smells that originate inside the HVAC system rather than in the living space itself. Common sources in Dallas include rodent activity in attic ductwork, smoke residue from previous occupants, and mustiness from condensation in flex ducts common in homes built after 2015 in areas like Oak Cliff and East Dallas. Our approach identifies the source first, often with a camera inspection that reveals the exact location, then treats with oxidation or encapsulation methods matched to the odor chemistry. We don’t mask smells with fragrances; we remove the source and document the condition before and after.
UV Light Installation
UV light installation places germicidal ultraviolet lamps inside the air handler or ductwork to inhibit mold and bacterial growth on coils and drain pans. We install Honeywell and Aprilaire UV systems sized to the CFM (cubic feet per minute) rating of your air handler, with lamp placement calculated for optimal exposure time. A typical residential installation in Dallas runs $450-$750 including the lamp, housing, and electrical connection. We photograph the installed position and include the manufacturer’s replacement schedule in your written job record, since UV lamps require annual bulb changes to maintain output.
Air Purifier Install
Air purifier installation adds whole-home filtration or electronic air cleaning downstream of your air handler, treating all conditioned air rather than a single room. We size and install Honeywell and Aprilaire media filters and electronic air cleaners, with MERV ratings selected based on your system’s fan capacity and your specific concerns. In Dallas, where cottonwood season and construction dust are annual events, a properly sized whole-home purifier reduces particulate load on the HVAC system itself. Every installation includes a written filter replacement schedule and the pressure-drop specifications so your technician can verify the system isn’t overworking the fan.
Allergen Reduction
Allergen reduction combines mechanical cleaning with targeted treatments to lower concentrations of dust mite debris, pet dander, pollen, and mold spores circulating through your ducts. This service is particularly relevant in Dallas during cedar fever season and the spring oak pollen period, when outdoor allergens enter the home and accumulate in the duct system. We use negative-pressure extraction (suction that pulls debris out while preventing it from entering your living space) followed by HEPA filtration of the exhaust air. The result is documented with before-and-after photos of the duct interior and, upon request, particle count readings at registers.

Brands We Service for Air Quality & Sanitizing
We install and service air quality equipment from Honeywell, Aprilaire, and Abatement Technologies, with hands-on experience across their full residential and light-commercial product lines. Our crews have installed hundreds of Honeywell UV treatment systems in Dallas homes, particularly in the Park Cities and North Dallas areas where older HVAC infrastructure benefits from coil-mounted germicidal lamps. We stock replacement UV bulbs and media filters for Honeywell and Aprilaire units, so maintenance visits don’t require a second trip.
Abatement Technologies supplies the portable HEPA filtration and negative-air machines we use during mold remediation work in contained areas. Their equipment is specified in many Dallas commercial contracts, and we apply the same containment protocols in residential jobs where airborne mold spore control matters. Whether you have Honeywell, Aprilaire, Abatement Technologies, or any other make of air quality equipment, we can service, repair, or replace it with a written price delivered before work starts.
BeforeAfterSigns You Need Air Quality & Sanitizing Right Now
- Musty or earthy odors when the AC cycles on. This often indicates mold growth on the evaporator coil or in the plenum, where condensation collects during Dallas’s humid months. The smell is the volatile organic compounds released by active fungal metabolism, and it won’t resolve with standard filter changes or duct cleaning alone.
- Increased allergy or asthma symptoms at home that improve when you leave. If family members experience congestion, coughing, or eye irritation primarily inside the house, the HVAC system may be distributing concentrated allergens or microbial fragments. We’ve documented cases in Richardson and Plano where duct contamination correlated with symptom patterns tracked by the homeowner over weeks.
- Visible mold or discoloration on registers, ceiling tiles, or around the air handler. Surface mold near supply registers usually indicates a larger colony upstream in the duct run. In Dallas’s climate, a small visible patch often conceals extensive growth in the flex duct or at joints where insulation has absorbed moisture.
- Recent water damage or plumbing leak that affected ceilings or walls near ductwork. Even after visible water is gone, residual moisture in duct insulation and surrounding framing supports bacterial and mold growth that becomes airborne once the system runs. We recommend inspection within 30 days of any water intrusion event.
- Persistent odors from previous owners, pets, or smoking that return after cleaning. Surface cleaning of carpets and vents doesn’t reach the odor-absorbing biofilm that coats duct interiors and HVAC components. Our oxidation treatments break down these compounds at the molecular level rather than covering them.
Our Air Quality & Sanitizing Process - Step by Step
- 1
Written estimate before arrival. We discuss your concerns by phone, review any prior service records if available, and provide a written price range before scheduling. Haven Standard Clause 1: no surprises, no “call for a quote.”
- 2
On-site inspection with camera documentation. Our technician arrives in a marked vehicle, uniformed and background-checked per Haven Standard Clause 3: Verified Crews. We insert a borescope camera into accessible duct runs and photograph the plenum, coil, and drain pan. You see what we see before any treatment is proposed.
- 3
Scope confirmation and written authorization. Based on the inspection, we confirm or adjust the written scope and price. The final authorization is signed before work begins. If the condition is better than expected and requires less treatment, the price goes down. This happens more often than you’d think.
- 4
Treatment execution with process documentation. We perform the agreed sanitizing, mold treatment, odor removal, or equipment installation using professional-grade tools from our equipment roster. For mold jobs, we establish containment and negative air pressure using Abatement Technologies HEPA machines. Every step is photographed for your record.
- 5
Post-treatment verification and photo record delivery. We re-inspect treated areas with the camera, capture after-condition images, and compile the full photo record into your job documentation. The 365-Day Done Right Promise is activated in writing before we leave. You receive the complete record by email within 24 hours.
How Much Does Air Quality & Sanitizing Cost in Dallas?
A typical bacteria sanitizing or odor removal treatment for a single HVAC system in Dallas runs $350-$550. Whole-home mold treatment with containment and HEPA-controlled remediation starts at $650 and ranges to $1,200 for extensive contamination across multiple duct runs. UV light installation with a Honeywell or Aprilaire unit is $450-$750 depending on lamp wattage and electrical access. Air purifier installation, including the media filter or electronic cleaner and housing, ranges $600-$950 for most residential systems.
Several factors move the price within these ranges. The size of your home and number of duct runs determine material and labor hours. Accessibility matters: attic-mounted air handlers in older Dallas homes like those in Lakewood or Kessler Park often require additional safety setup compared to closet-mounted units in newer construction. The severity of contamination affects treatment intensity, and whether we’re addressing a single issue or combining services, such as sanitizing plus UV installation, changes the scope.
To avoid overpaying, request that any quote specify the exact treatment area, the products or equipment to be used, and whether the price is fixed or estimated. We publish our ranges because Haven Standard Clause 1 requires it. Be cautious of per-vent pricing, which incentivizes minimal work per opening, and of teaser rates that don’t include the necessary treatments. Our written price covers the entire system, agreed before work starts.
Every estimate we provide is free and carries no obligation. Bring a competitor’s written quote, and we’ll deliver a free second opinion with our number beside it. Call (469) 405-6133 to schedule.

Frequently Asked Questions - Air Quality & Sanitizing in Dallas
Air quality and sanitizing targets biological contamination, odors, and airborne pollutants with chemical or physical treatments, while duct cleaning removes accumulated dust and debris through mechanical agitation and extraction. Duct cleaning improves airflow and reduces particulate load; sanitizing addresses the mold, bacteria, and odor sources that cleaning alone doesn’t eliminate. Many Dallas homes need both, and we scope each separately so you don’t pay for unnecessary treatment.
A standard bacteria sanitizing or odor treatment for a single residential system takes 2-3 hours from arrival to completion. Mold remediation with containment setup and HEPA-controlled removal typically requires 4-6 hours, and UV light or air purifier installation runs 2-4 hours depending on electrical access. We confirm the expected duration in your written scope so you can plan accordingly. Call (469) 405-6133 for an exact time estimate based on your system.
Most homeowners pay $350-$850 for a complete Air Quality & Sanitizing - Mesquite treatment, with bacteria and odor work at the lower end and mold remediation or equipment installation at the higher end. The exact price depends on your home’s size, system accessibility, and contamination severity. We provide a written price before any work starts, and our free estimates include no obligation to proceed. Call (469) 405-6133 for your specific quote.
