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.

Frisco’s rapid growth since 2015 means tens of thousands of homes here were built during the same construction boom, often with HVAC systems that ran through drywall dust and off-gassing materials before the first owner moved in. We’ve photographed the inside of duct runs in Frisco’s newer neighborhoods - home to home - and found that post-construction debris combined with North Texas pollen loads creates a specific problem: registers that look clean while the plenum (the main distribution box above your furnace) harbors material that recirculates with every cycle. Our air quality and sanitizing service addresses this at the source, not with surface treatments.
Tomas Reyes established CleanRun in 2013 on a straightforward premise: show the customer what you found, quote the work in writing, then show them what changed. That standard still governs our Air Quality & Sanitizing in Frisco. Our technicians are background-checked and uniformed under Haven Standard Clause 3: Verified Crews, and they arrive with professional-grade equipment from trade-recognized manufacturers. The 365-Day Done Right Promise applies to every sanitizing and air quality treatment we perform.
What Our Air Quality & Sanitizing Service Includes
Mold Treatment
Mold treatment targets microbial growth inside the duct run (the continuous channel from plenum to register), on the evaporator coil, or at the return air pathway - areas where condensation and organic material create sustained moisture. In Frisco, we regularly find mold colonization at the evaporator coil pan and at the first elbow of flex duct runs in attics, where summer humidity peaks above 70% and temperature differentials produce condensation. CleanRun treats these areas with EPA-registered antimicrobial agents applied through negative-pressure extraction equipment, then documents the before and after condition with photographs of every treated surface. The photo record is delivered as part of the standard job documentation.

Bacteria Sanitizing
Bacteria sanitizing reduces microbial load throughout the HVAC distribution system, particularly important after water intrusion, rodent activity, or following illness in the household. We apply this service when a customer reports persistent “sick building” symptoms - headaches, respiratory irritation, or fatigue that improves when leaving the house - or when our camera inspection reveals biofilm accumulation on duct walls. CleanRun uses professional-grade fogging and contact application methods with Abatement Technologies protocols, measuring treatment coverage with UV fluorescence markers to verify reach into every branch of the system. The written scope specifies which duct runs receive treatment and which showed no indication for intervention.

Odor Removal
Odor removal addresses persistent smells that originate in the HVAC system rather than the living space, including pet dander accumulation, smoke residue, cooking oil vapor deposition, and the musty scent of microbial activity. Frisco’s hard water and high mineral content can accelerate scale buildup on coils that traps organic material and produces odors when heated. Our process combines source removal through mechanical agitation and negative-pressure extraction with targeted oxidizing treatments at the identified origin point - we don’t mask smells with fragrances. Every odor job includes a written identification of the source we found and the specific treatment applied, plus the standard before-and-after photo record.

UV Light Installation
UV light installation places germicidal ultraviolet lamps at strategic points in the HVAC system - typically at the evaporator coil and in the return air stream - to inhibit microbial growth on wet surfaces and reduce airborne bioburden. These are not consumer-grade plug-in units; professional UV systems from Honeywell and Aprilaire require precise placement, proper shielding to prevent UV degradation of nearby plastics, and electrical integration with the furnace control board. CleanRun sizes the lamp output to the system CFM (cubic feet per minute) and documents the installation location, lamp intensity, and recommended replacement schedule in the written job record. We install UV systems in Frisco homes where microbial recurrence is a documented pattern or where household members have immunocompromised conditions.

Air Purifier Install
Air purifier installation for whole-home treatment means in-line media filters, electronic air cleaners, or hybrid systems mounted at the air handler, not portable room units that treat limited square footage. We size these installations to the existing system’s static pressure capacity - adding too much resistance can reduce airflow, strain the blower motor, and void equipment warranties. CleanRun specifies the pressure drop of any recommended purifier and verifies post-installation airflow with a manometer (a precision pressure gauge). Our equipment roster includes Honeywell and Aprilaire whole-home systems, and we document the initial pressure reading, the installed unit’s rated pressure drop, and the post-installation verification in the written job record.

Allergen Reduction
Allergen reduction combines mechanical removal of accumulated pollen, dust mite debris, and pet dander from the full duct system with targeted filtration upgrades and, where indicated, sanitizing treatment. Frisco’s location in the Blackland Prairie means spring cedar and oak pollen loads are among the highest in Texas, and we’ve photographed register accumulations in Frisco homes that measure in centimeters, not millimeters. CleanRun’s allergen service includes a particle count measurement at the supply registers before and after cleaning, using a calibrated laser particle counter, so the customer has numerical documentation of the change - not just our word that the ducts are cleaner.

Brands We Service for Air Quality & Sanitizing

We’ve installed and serviced Honeywell whole-home air purifiers and UV systems in hundreds of Frisco-area homes, and we stock replacement lamps and media filters for their F100, F200, and F300 series electronic air cleaners. Honeywell’s UV lamps require specific intensity ratings for coil-mounted versus air-stream applications, and we verify output with a UV meter at installation and annually thereafter - a step many installers skip because the lamp appears to glow.
Aprilaire’s 5000-series electronic air cleaners and 1900-series media cabinets are common in the higher-efficiency HVAC systems installed in Frisco’s 2015-2025 construction, and we’ve diagnosed pressure-drop issues caused by incorrect filter media upgrades in these units. We also specify and install Guardsman antimicrobial coatings for duct interiors in commercial and residential applications where mold recurrence has been documented. Whether you have Honeywell, Aprilaire, Guardsman, or any other make of air quality equipment, we can service, repair, or replace it - and we’ll put the scope and price in writing before touching a single panel.
Before
AfterSigns You Need Air Quality & Sanitizing Right Now
- Persistent musty or chemical odors when the HVAC cycles. If you smell something distinct when the blower engages that fades when it stops, the source is almost certainly in the duct system or air handler, not the living space. This pattern indicates microbial activity, rodent presence, or absorbed volatile compounds that re-release with airflow - all conditions that sanitizing treatment can address once the source is identified.
- Visible mold around registers or on the return air grille. Surface mold at the register often signals more extensive colonization upstream, where the duct run stays dark and may hold moisture from duct leakage or poor insulation. Cleaning the visible spot without treating the full system typically results in rapid recurrence, which is why our mold treatment includes camera inspection of the full run, not just the accessible opening.
- Increasing allergy or asthma symptoms that improve when you leave home. This is one of the most reliable indicators of elevated indoor bioburden, and it’s particularly common in Frisco’s newer neighborhoods where tight building envelopes trap recirculating particles. If your symptoms are worse in the morning after the system has cycled overnight, the HVAC distribution path is the likely vector.
- Recent water intrusion, roof leak, or condensate overflow. Any moisture event in or near the duct system creates conditions for microbial growth within 24-48 hours, even if the visible water was quickly removed. We recommend inspection and, if indicated, sanitizing treatment after any event that wetted duct interiors, insulation, or the plenum.
- Home purchase within the last 12 months with no duct history. Frisco’s resale market moves fast, and many buyers receive no documentation of prior duct maintenance. Our camera inspection often finds construction debris, pet dander from prior owners, or evidence of DIY cleaning attempts that left debris loosened but not removed - a condition worse than undisturbed accumulation because the particles are now respirable.
Our Air Quality & Sanitizing Process - Step by Step

- 1
Written estimate with scope and price. Every Frisco air quality job begins with a technician inspection, not a phone quote. We access the plenum, inspect accessible duct runs with a borescope camera, and identify the specific conditions present. The written scope lists what we found, what we recommend, the exact price, and what is not included - signed by the technician and the customer before any work begins. Haven Standard Clause 1: Written Price Before Work Starts.
- 2
Protective preparation and system isolation. We seal registers, protect flooring and furnishings, and isolate the HVAC system to prevent cross-contamination during treatment. For jobs involving antimicrobial application, we calculate the required ventilation rate and establish exhaust pathways before opening any chemical container.
- 3
Source removal and mechanical cleaning. All sanitizing treatments begin with physical removal of accumulated debris using Rotobrush mechanical agitation and Nikro negative-pressure extraction equipment. Chemical treatments applied over debris layers are ineffective - the debris must come out first. We photograph every duct run before this step begins.
- 4
Targeted sanitizing or equipment installation. Based on the written scope, we apply EPA-registered antimicrobial agents, install UV lamps or air purifiers, or treat specific odor sources. UV installations include electrical testing, intensity verification, and documentation of lamp replacement date. All chemical applications include dwell-time verification and post-treatment ventilation measurement.
- 5
Documentation, verification, and photo record delivery. The technician photographs every treated duct run after completion, records any measurement data (particle counts, pressure readings, UV intensity), and delivers the complete job record to the customer before leaving. This includes the written scope, before-and-after photos, product labels and SDS sheets for any chemicals used, and the 365-Day Done Right Promise documentation.
How Much Does Air Quality & Sanitizing Cost in Frisco?
A typical bacteria sanitizing or odor removal treatment for a single-system Frisco home runs $280-$450, while whole-system mold treatment with full duct cleaning and antimicrobial application ranges from $480-$780 depending on system size, accessibility, and the extent of colonization found. UV light installation with a professional-grade Honeywell or Aprilaire unit, including electrical integration and verification, typically falls between $380-$620 per lamp location. Air purifier installation, which may require duct modification and static pressure verification, ranges from $450-$890 for whole-home in-line units.
Several factors move these ranges. Homes over 3,500 square feet or with dual-zone systems require additional material and labor. Attic duct runs in Frisco’s summer heat slow technician progress and extend job duration. The presence of flex duct (common in 2015-2020 Frisco construction) versus rigid metal duct affects access and treatment method. We specify all of these variables in the written estimate - no surprises after work begins.
The most reliable way to avoid overpaying is to demand the same documentation CleanRun provides: a written scope that identifies what was actually found, not generic language; a fixed price for that scope; and photographic evidence of results. The $79 coupon model common in this industry typically covers a brief vacuum at the register, not the full system treatment that addresses the source. Our Free Second Opinion on Any Written Estimate lets you bring a competitor’s quote; we’ll inspect, document what we find, and put our number next to theirs - both in writing.
Every estimate in Frisco is free and carries no obligation. The technician will show you the camera footage, explain what it indicates, and leave you with the written scope whether you schedule or not.

Frequently Asked Questions - Air Quality & Sanitizing in Frisco

Air Quality & Sanitizing in Little Elm targets biological contaminants and persistent odors that standard duct cleaning, which removes loose debris and dust, does not address. While duct cleaning improves airflow and reduces particulate load, sanitizing applies EPA-registered antimicrobial agents, installs UV or filtration equipment, or treats specific sources of mold, bacteria, or odor - addressing the living or chemical contamination that remains after debris removal. Call (940) 290-8552 for a free inspection to determine which service your system needs.
A typical residential sanitizing treatment takes 3-5 hours for a single-system home, while UV or air purifier installation may extend to 4-6 hours depending on electrical access and duct configuration. Mold treatment with full system cleaning requires the longest duration, often 5-8 hours, because of the extended dwell times required for antimicrobial effectiveness and the thorough documentation we perform. We schedule enough time to complete the work without rushing, and the written scope specifies the expected duration before you commit.
Most Frisco homeowners pay between $280-$780 for air quality and sanitizing services, with bacteria and odor treatments at the lower end, mold remediation with full cleaning in the middle, and UV or air purifier installations at the higher end depending on equipment and system complexity. The exact price depends on what our camera inspection reveals, which is why we don’t quote over the phone - the written estimate, free and with no obligation, follows the inspection. Call (940) 290-8552 to schedule.
Yes - we install, service, and repair Honeywell and Aprilaire whole-home air purifiers, UV systems, and electronic air cleaners, and we stock replacement lamps, media, and components for their most common residential models. Our technicians verify system compatibility and measure static pressure impact before recommending any upgrade, and we document these readings in the written job record. We also service all other major brands and can source components for less common equipment.
Active water intrusion, visible mold spreading beyond the register area, or severe respiratory symptoms in household members warrant prompt attention - we prioritize these inspections. For chronic odors, gradual allergy symptom increase, or preventive concerns, scheduling within the next few business days is typically appropriate and allows proper preparation. Our live answering takes calls 24/7 to discuss urgency and schedule appropriately; we do not charge emergency premiums for standard business-hours scheduling.
Every job is backed by the 365-Day Done Right Promise: if the work is not right, CleanRun makes it right, documented in writing on every invoice - not a policy subject to manager approval. For sanitizing treatments, this covers recurrence of the treated condition within the warranty period. UV lamps carry manufacturer warranties for ballast and housing defects; lamp output degrades normally with age and is not warrantied beyond rated lifespan, though we document initial intensity and recommend replacement intervals. Haven Standard Clause 5: Accountable Workmanship.
Ensure access to the HVAC system, attic entry if applicable, and all registers; clear fragile items from surfaces near registers and the air handler. If anyone in the home has chemical sensitivities or respiratory conditions, inform us when scheduling so we can select appropriate products and ventilation protocols. You do not need to leave the home during most treatments, though we may recommend brief evacuation during certain application phases - this will be specified in the written scope before work begins. Call (940) 290-8552 with any specific concerns.
