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 New Braunfels Homeowners
Air Quality & Sanitizing - New Braunfels typically addresses mold, bacteria, odors, and airborne allergens inside your ductwork and HVAC system, with whole-home treatments ranging from $450 to $1,200 depending on the scope. Since 2013, CleanRun Air Duct Cleaning New Braunfels has delivered documented photo records of every duct run we’ve treated, backed by our 365-Day Done Right Promise in writing on every job. We’re independently owned and operated under the Haven Standard, and every estimate starts with a written price before any work begins - call (830) 549-6847 to schedule yours.
New Braunfels sits at the edge of the Texas Hill Country where humidity swings between spring Gulf moisture and dry summer heat, conditions that push mold and bacteria growth inside duct systems that homeowners never see. We’ve treated systems in Canyon Lake homes where seasonal lake humidity created visible mold at the plenum - the main distribution box where all duct runs connect - and in newer construction near Veramendi where tight building envelopes trap off-gassing and construction debris for years after move-in. Our crews document what the camera finds before proposing any treatment, so you see what we see.
Tomas Reyes leads every operational decision at CleanRun, and our background-checked, uniformed technicians arrive identified by name under Haven Standard Clause 3: Verified Crews. We don’t use per-vent pricing or teaser coupons. Every job gets one flat price per system, agreed in writing before a single panel comes off.
What Our Air Quality & Sanitizing Service Includes
Mold Treatment
Mold treatment targets visible fungal growth inside duct runs - the individual pathways that carry conditioned air to each room - and at the plenum where those runs converge. In New Braunfels, we regularly find mold at the first elbow downstream of the evaporator coil, where cold air meets humid return air and condensation collects on fiberglass liner. Our process begins with a borescope inspection: a camera on a flexible cable that records video inside the ductwork, so you see the growth before we quote treatment. We apply EPA-registered antimicrobial through negative-pressure extraction equipment from Nikro, which contains overspray and removes dead spores in the same operation. The photo record shows the treated surface after completion.
You’ll know mold treatment is necessary when you smell mustiness at registers - the visible grilles where air enters rooms - or when family members experience worsening allergy symptoms only at home. We don’t treat based on smell alone; the camera shows the extent before we write the price.

Bacteria Sanitizing
Bacteria sanitizing addresses microbial contamination that doesn’t produce visible mold but still circulates through your living space, including Legionella, E. coli, and common household bacteria that colonize drip pans and wet sections of the air handler. This service matters most after water intrusion, a failed condensate pump, or any event that leaves standing moisture in the system. Our technicians use professional-grade fogging equipment to distribute sanitizer through the entire duct network, not just the accessible sections near the furnace. The product we apply is rated for HVAC systems and leaves no residue that would affect air quality after treatment.
We recommend bacteria sanitizing after any flooding event in New Braunfels, including the flash flooding that affects low-lying neighborhoods near the Guadalupe River. The photo record includes images of the drip pan and evaporator housing before and after treatment, so you have documentation for insurance or home sale disclosure if needed.

Odor Removal
Odor removal eliminates persistent smells that originate inside the duct system rather than in the living space itself - pet urine that seeped into floor registers, smoke damage from a kitchen fire, or the sour smell of a dead rodent in a wall cavity connected to the return. Surface cleaning with household products won’t reach the full length of a duct run where odor molecules adhere to dust and fiberglass surfaces. Our process combines mechanical agitation with negative-pressure extraction to remove the source material, followed by targeted treatment of the affected section.
In Timberwood Park and Bulverde, we’ve removed odors from homes where previous owners kept indoor pets for years and the new owners couldn’t locate the source of smell. The camera found concentrated debris at the boot connections - the transitions between duct and register - where pet hair and dander had compacted over a decade. We showed the photo record, wrote the price, and removed the material. No guesswork.

UV Light Installation
UV light installation places a germicidal ultraviolet lamp inside the air handler or at the coil, where it continuously irradiates surfaces that stay wet during cooling season and would otherwise support mold and bacterial growth. This is preventive equipment, not a cleaning service, and it works only where the light has direct line-of-sight. We install Honeywell and Aprilaire UV systems that mount at the coil or in the return plenum, wired to operate only when the blower runs to maximize lamp life.
A UV lamp won’t clean existing contamination; it prevents new growth on illuminated surfaces. We install these in New Braunfels homes where the coil has been treated for mold and the homeowner wants to prevent recurrence, particularly in lake-area properties where humidity stays elevated through October. The installation includes a written price, photos of the mounting location, and lamp replacement schedule so you know when the bulb loses effectiveness.

Air Purifier Install
Air purifier installation adds whole-home filtration or electronic air cleaning downstream of the air handler, treating every cubic foot of air that passes through the HVAC system rather than relying on portable units that only clean single rooms. We install Honeywell and Aprilaire media filters rated at MERV 13 and above, plus electronic air cleaners that charge and capture particles too small for standard filtration. Every installation starts with a static pressure test - measuring the resistance the existing blower can overcome - because adding restrictive filtration without this check can damage the system.
New Braunfels homeowners near construction zones in Veramendi or along the 46 corridor often choose this upgrade after we show them the debris load in their photo record. The written price includes the filter cabinet, the media, and the pressure test. We don’t install equipment that the blower can’t support; that’s Haven Standard Clause 1 in practice.

Allergen Reduction
Allergen reduction is a targeted service for households where occupants have diagnosed allergies or asthma, focusing on the removal of dust mite debris, pollen, pet dander, and cockroach allergen from the full duct system. Standard duct cleaning removes loose debris; allergen reduction adds HEPA-filtered negative-pressure extraction and sealed containment to prevent redistribution during the cleaning process. We use Abatement Technologies portable HEPA units that maintain containment at 0.3 microns, the size of the most penetrating particles.
We’ve performed this service in Live Oak and Universal City homes where children have asthma triggers documented by allergists, and we also offer our Air Quality & Sanitizing in Cibolo for families in that area. The photo record shows particle counts before and after, measured with a calibrated laser particle counter, so the improvement is documented rather than claimed. The written price covers the full system; there is no per-vent add-on.

Brands We Service for Air Quality & Sanitizing

We install and service Honeywell whole-home air purifiers and UV systems regularly in New Braunfels, with direct experience mounting their F100 and F300 electronic air cleaners in both horizontal and vertical air handlers common in Hill Country homes. Their UV2400U lamp installs at the coil centerline where it maintains maximum intensity on the wettest surface, and we stock replacement bulbs so you’re not waiting on shipping when the 9,000-hour lifespan expires. We’ve also installed Aprilaire 5000 series electronic air cleaners in Schertz and Selma homes where the owner wanted MERV 16 performance without the static pressure penalty of dense media. Ask about Air Quality & Sanitizing - Seguin if you’re nearby.
Our equipment roster includes Rotobrush mechanical agitation tools and Nikro negative-pressure extractors for the cleaning portion of air quality work, plus Guardsman antimicrobial products applied according to manufacturer specifications. Whether your system is Honeywell, Aprilaire, or any other make, we can inspect it, document what we find, and write a price for any needed treatment. We don’t require brand loyalty; we require that the equipment works as specified when we leave.
Before
AfterSigns You Need Air Quality & Sanitizing Right Now
- Musty smell when the AC first cycles on. This indicates mold or mildew growth at the coil, plenum, or first few feet of duct downstream, where cold surfaces meet humid air. The smell fades after a minute because your nose adapts, but the contamination continues circulating. We’ve found active mold in New Braunfels homes where the owner had stopped noticing the smell entirely.
- Allergy symptoms that worsen at home and improve away from home. When sneezing, congestion, or itchy eyes track with time spent in the house, the HVAC system is likely distributing allergens you’ve become sensitized to. This pattern is common in newer homes near Cibolo and Schertz with tight construction that traps indoor pollutants.
- Visible dust accumulation on registers within weeks of cleaning. Heavy debris at supply registers often means the duct interior is shedding material downstream of the filter, either because the filter is bypassing air or because the duct itself is deteriorating. The photo record shows whether the issue is surface debris or liner breakdown.
- Recent water intrusion or plumbing leak near the air handler. Any event that wets the duct interior or surrounding framing creates conditions for bacterial and mold growth within 48 hours. We treat these as priority inspections in New Braunfels, particularly in homes near the Comal River floodplain.
- Unexplained odors that don’t correspond to any visible source. When you’ve cleaned carpets, emptied trash, and checked appliances but the smell persists, the duct system is the remaining pathway. Our borescope locates the source section without tearing into walls.
Our Air Quality & Sanitizing Process - Step by Step

- 1
System inspection with borescope documentation. We access the plenum and representative duct runs through existing service openings, recording video of interior conditions before proposing any work. You see the footage before we write the price. This inspection is included in every estimate at no charge.
- 2
Written price delivered before work begins. Based on what the camera shows, we specify the exact scope - which duct runs need treatment, what equipment will be used, and what the flat price covers. Haven Standard Clause 1 requires this in writing before any panel is removed. There is no “call for a quote” at CleanRun; the quote is written in front of you.
- 3
Containment and negative-pressure setup. For sanitizing and mold treatment, we seal registers and establish negative pressure using Nikro portable extraction equipment, preventing contamination from escaping into living spaces during the work. HEPA filtration on the exhaust captures particles at 99.97% efficiency at 0.3 microns.
- 4
Treatment application with mechanical agitation. We apply the appropriate antimicrobial or sanitizer using equipment sized to the duct diameter, with mechanical brushing from Rotobrush tools to dislodge adhered material. The negative-pressure system removes debris as it’s freed, rather than pushing it deeper into the system.
- 5
Post-treatment photo record and verification. After completion, we photograph the treated surfaces with the borescope for comparison to the pre-treatment images. This documented photo record is delivered as part of the standard job record, along with the written scope and the 365-Day Done Right Promise. If the work is not right, we make it right - in writing, not as a favor.
How Much Does Air Quality & Sanitizing Cost in New Braunfels?
A typical bacteria sanitizing or odor removal for a single-system home in New Braunfels runs $450-$680; see our Air Quality & Sanitizing pricing for full details. Whole-system mold treatment, where the camera shows growth at multiple duct runs and the plenum, typically ranges from $890-$1,200 depending on system size and accessibility. UV light installation with a Honeywell or Aprilaire unit starts at $380 for a single-lamp coil mount and reaches $650 for dual-lamp systems with installation in restricted attic spaces. Air purifier installation, including the cabinet, initial media, and static pressure verification, ranges from $520-$940 for whole-home media filters and $780-$1,150 for electronic air cleaners.
Several factors move the price within these ranges. System size matters: a 5-ton system with 18 duct runs requires more treatment product and more time than a 2.5-ton system with 10 runs. Accessibility affects labor - attics with limited clearance in older Canyon Lake homes take longer than equipment closets in newer Veramendi construction. The extent of contamination shown in the borescope determines whether we treat the full system or can isolate to affected sections.
To avoid overpaying, reject any quote that won’t put the full price in writing before work starts, or that prices per vent rather than per system. Per-vent pricing incentivizes the technician to find more vents to charge for. CleanRun’s flat price per system, agreed under Haven Standard Clause 1, removes that conflict. The free estimate includes the borescope inspection, the photo record review, and the written price with no obligation. Call (830) 549-6847 to schedule.

Frequently Asked Questions - Air Quality & Sanitizing in New Braunfels

Air quality and sanitizing is the treatment of mold, bacteria, odors, and allergens inside ductwork and HVAC components, using EPA-registered products and professional extraction equipment rather than surface cleaning. At CleanRun, every treatment starts with a borescope inspection that records actual conditions inside your plenum and duct runs, followed by a written price before any work begins. The service concludes with a documented photo record showing treated surfaces, delivered as part of your job record.
A typical whole-system sanitizing or odor removal takes 3-5 hours for a single-system home, while mold treatment with full containment and post-treatment verification may extend to a full day. UV light and air purifier installations require 2-3 hours including the static pressure test and documentation. We schedule with a specific arrival window, not an all-day wait, and the technician is identified by name before arrival under Haven Standard Clause 3. Call (830) 549-6847 for available dates.
Most homeowners in New Braunfels pay between $450 and $1,200 depending on the service: bacteria sanitizing and odor removal typically fall at the lower end, whole-system mold treatment at the higher end, with UV and filtration installations in the mid-range. Every estimate is free, includes the borescope inspection, and produces a written flat price per system before any work starts - no per-vent add-ons, no coupon teaser rates. Call (830) 549-6847 for an exact quote on your system.
Yes, we install and service Honeywell and Aprilaire whole-home air purifiers, UV lamps, and electronic air cleaners, with direct experience mounting their equipment in the horizontal air handlers common in New Braunfels attics. We stock replacement UV bulbs and filter media for these brands, and we verify static pressure compatibility before installing any filtration upgrade. If you have a different brand, we inspect and document before recommending any work.
We prioritize mold inspections within 24-48 hours when active water intrusion is ongoing or when occupants have compromised immune systems, but air quality and sanitizing is a scheduled service rather than an emergency dispatch. We don’t claim same-day availability because proper containment setup and documentation take time that rushed work skips. If you’ve had recent flooding, call (830) 549-6847 and we’ll schedule the earliest possible inspection with full borescope documentation.
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 - not a policy subject to manager approval. For UV lamp installations, we also warranty the electrical connections and mounting for one year. The antimicrobial products we apply carry their own manufacturer efficacy ratings, and we follow those specifications precisely so the treatment performs as labeled.
Clear a 3-foot workspace around the air handler and the return air grille, and ensure pets are secured in a separate room during the inspection and treatment. You don’t need to clean ducts beforehand; we document actual conditions, not staged ones. Have your HVAC maintenance records available if you’ve had prior service, and be prepared to point out any specific odors or symptoms you’ve noticed. The technician will show you the borescope footage and write the price before any work begins.
