AfterTrusted Air Quality & Sanitizing for Aurora Homeowners
Air Quality & Sanitizing pricing for service in Aurora, CO typically addresses mold, bacteria, allergens, and persistent odors inside your HVAC system, with whole-home treatments running $400-$1,200 depending on scope and whether UV or filtration upgrades are included. CleanRun Duct Repair & Cleaning has delivered documented photo records of every duct run since 2013, serving over 52,000 homes with written prices agreed before any work starts. Call (720) 513-5159 for a free estimate with no obligation.
We’ve pulled cameras through ductwork in homes from Air Quality & Sanitizing in Aurora to Cherry Hills Village, and the pattern repeats: homeowners who bought between 2015 and 2025 paid premium prices for tight envelopes and high-efficiency HVAC, then discovered the same sealed construction that saves energy also traps microbial growth, construction debris, and off-gassing from new materials. Aurora’s semi-arid climate with sudden humidity spikes during summer monsoons creates ideal conditions for mold colonization in evaporator coils and plenum boxes, especially in newer subdivisions where builders prioritized speed over duct cleanliness. Our crews document what we find, photograph every run before and after, and deliver a written scope with a fixed price before a single panel comes off.
What Our Air Quality & Sanitizing Service Includes
Mold Treatment
Mold treatment targets active fungal growth inside duct runs, plenum boxes (the main distribution chamber connected to your air handler), and evaporator coil housings where condensation collects. In Aurora, we regularly find Cladosporium and Penicillium species at the first elbow downstream of the coil, particularly in homes built during the 2018-2022 construction boom where insulation was installed before ducts were fully sealed. CleanRun treats affected areas with EPA-registered fungistatic agents applied through negative-pressure extraction equipment from Abatement Technologies, then verifies clearance with visual documentation before the system is returned to service. Every mold treatment includes the standard Documented Photo Record showing the colony location, treatment application, and post-treatment condition of each affected run.
Bacteria Sanitizing
Bacteria sanitizing eliminates microbial contamination that standard duct cleaning leaves behind, particularly Legionella, Staphylococcus, and biofilm-forming organisms that adhere to duct walls. This service matters most for households with immunocompromised members, recent water intrusion events, or systems that sat dormant during extended vacancy, which we see frequently in Aurora’s investor-owned rental properties near the Anschutz Medical Campus. CleanRun applies hospital-grade sanitizers through mechanical fogging devices that reach the full perimeter of round and rectangular ductwork, with concentration verified by contact time and coverage documentation per Haven Standard Clause 2: Documented Methods. The photo record shows fog penetration at each register location.
Odor Removal
Odor removal addresses persistent smells that originate inside the HVAC system rather than from ambient sources, including pet dander accumulation, smoke residue, rodent activity, and volatile organic compounds from previous owners’ cleaning products. Aurora’s hard water compounds the problem: mineral scale on evaporator coils traps organic material that produces a musty, “wet sock” smell when the system cycles on, especially in homes east of E-470 where water hardness exceeds 180 ppm. CleanRun identifies the source with borescope inspection, treats the affected components with oxidizing agents that break odor molecules at the source rather than masking them, and provides before-and-after photos of the specific location where the smell originated. We do not sell deodorizer tablets or scented filters that would violate Haven Standard Clause 4: No Masking Agents.
UV Light Installation
UV light installation places germicidal ultraviolet-C lamps at the evaporator coil and return plenum to inhibit microbial growth on wet surfaces and in the airstream. This is a preventive measure, not a cleaning substitute, and works best for Aurora homeowners who’ve already addressed existing contamination or who want to protect a new system installation. CleanRun sizes UV output to the coil dimensions and airflow rate, using lamps from Honeywell and Aprilaire with published dosage specifications that customers can verify independently. Installation includes a written lux measurement at the coil surface, lamp replacement schedule, and integration with the existing electrical without modifying factory wiring. The photo record documents lamp placement, electrical connection method, and coil condition at installation.
Air Purifier Install
Whole-home air purifier installation adds filtration or electronic cleaning capacity at the central return, treating all air distributed through the duct system rather than relying on portable units in individual rooms. Aurora’s wildfire smoke events, particularly from fires in the Pacific Northwest that drift across the plains in late summer, have driven increased demand for MERV 16+ or electronic air cleaners that capture sub-micron particulate. CleanRun installs Honeywell and Aprilaire whole-house units with published CADR (clean air delivery rate) and pressure-drop specifications, verifies that the selected unit does not exceed the HVAC manufacturer’s maximum external static pressure, and documents the pre-installation pressure reading and post-installation verification. Written price includes the unit, mounting hardware, electrical connection, and first-year filter or cell.
Allergen Reduction
Allergen reduction combines mechanical cleaning, source removal, and filtration upgrade to lower concentrations of pollen, dust mite fragments, pet dander, and cockroach allergen in the conditioned air. This service is most requested in Aurora during March through June when cottonwood pollen counts spike and in September when ragweed peaks, particularly in homes with slab-on-grade construction where soil gases and allergens enter through perimeter gaps. CleanRun performs full-system negative-pressure extraction with Rotobrush contact cleaning of each duct run, treats registers and boots where allergen accumulation is heaviest, and recommends filtration upgrades with specific MERV ratings matched to the blower capacity. The photo record shows debris volume removed from each run and the condition of previously clogged registers.

Brands We Service for Air Quality & Sanitizing
We’ve installed and serviced hundreds of Honeywell whole-home air purifiers and UV systems across Aurora, Centennial, and Air Quality & Sanitizing in Denver, and we stock replacement lamps, filters, and electronic cells for their F100, F200, and F300 series. Our technicians carry the Honeywell installation manual on tablet for reference during sizing verification, and we document the model number, serial number, and installation date in every job record for warranty registration.
Aprilaire units are equally common in the homes we serve, particularly their 5000 series electronic air cleaners and 1900 series media cabinets that we encounter in Parker and Lone Tree new construction. We’ve replaced Aprilaire cells in systems where previous contractors installed incompatible third-party alternatives that voided the warranty, and we verify OEM part numbers against the unit data plate before quoting. Whether you have Honeywell, Aprilaire, or any other make, we can source specifications, verify compatibility, and perform installation or maintenance with documented methods.
BeforeAfterSigns You Need Air Quality & Sanitizing Right Now
- Persistent musty or chemical smell when the system runs. Odors that intensify when the blower cycles on and fade when it stops indicate contamination inside the ductwork or air handler, not ambient air. In Aurora homes with finished basements, we frequently find mold growth at the return duct penetration through the foundation wall where condensation forms against concrete.
- Visible mold or discoloration at registers or in the return grille. Any fungal growth visible from the living space suggests more extensive colonization upstream where conditions are darker and more humid. We document the extent with borescope photography before quoting treatment, so you see the full scope before agreeing to a price.
- Increased allergy or asthma symptoms that correlate with HVAC use. If symptoms worsen within 30 minutes of the system cycling on and improve when you leave home, the distribution system is likely the vector. Aurora’s high pollen counts compound this effect when ducts serve as reservoirs for seasonal allergens.
- Recent water intrusion, roof leak, or plumbing repair. Even brief moisture exposure inside ductwork can initiate mold growth within 48-72 hours, and DIY drying efforts rarely reach the interior of insulated flex duct. We inspect with cameras before recommending treatment versus replacement of affected sections.
- Home purchase within the last 12 months with no duct documentation. New construction in Stonegate, Sky Ranch, and other Aurora developments often left construction debris inside ducts, and resale homes may carry contamination from previous owners’ pets, smoking, or unreported water events. A documented inspection establishes baseline condition.
Our Air Quality & Sanitizing Process - Step by Step
- 1
Written estimate before arrival. We gather square footage, system type, and symptom description by phone, then deliver a price range with ceiling via email or text before scheduling. Haven Standard Clause 1: Written Price First. No “call for a quote,” no dispatch-and-disclose.
- 2
On-site inspection with borescope documentation. The technician introduces themselves by name, verifies identity against the appointment record, and inserts a lighted camera into representative duct runs to show you the actual condition. You see the image in real time; we save it for the before-and-after comparison.
- 3
Scope confirmation and fixed-price agreement. Based on inspection findings, the technician confirms or adjusts the written scope, notes any additional contamination discovered, and obtains your signature on the final price before work begins. This document becomes part of your job record.
- 4
Treatment execution with photo documentation. Each duct run is photographed before treatment, treated according to the specified method (mechanical cleaning, chemical application, UV installation, or filtration upgrade), and photographed again immediately after. The crew logs equipment used, chemical concentrations, and contact times where applicable.
- 5
Deliverable review and 365-Day Done Right Promise activation. The technician reviews the photo record with you, explains any recommendations for ongoing maintenance or filtration, and provides the written warranty document. The 365-Day Done Right Promise is in effect from this moment; if the problem recurs or the work proves incomplete, we return at no charge.
How Much Does Air Quality & Sanitizing Cost in Aurora?
A typical bacteria sanitizing or odor removal treatment for a single-system Aurora home runs $400-$650, while Air Quality & Sanitizing - Commerce City customers can expect similar mold treatment with full-system cleaning ranging $800-$1,200 depending on colony extent and whether duct replacement is required. UV light installation with a single-lamp setup at the evaporator coil typically costs $350-$550; dual-lamp systems with return-air protection run $600-$900. Whole-home air purifier installation, including the Aprilaire 2210 media cabinet or Honeywell F100 bypass unit with professional mounting and electrical, ranges $800-$1,500 with the unit, labor, and first-year media included.
Several factors move these ranges. System accessibility matters: crawl space air handlers in older Aurora homes near Original Aurora require additional labor time versus basement mechanical rooms in newer construction. The number of duct runs and registers directly affects cleaning scope; a 2,000-square-foot home with 12 registers costs less than a same-size home with 18 registers and a zoned system. Contamination severity determines whether standard cleaning suffices or whether replacement of insulated flex duct is more economical than repeated treatment. We disclose these variables during the phone estimate and confirm with camera evidence on site.
To avoid overpaying, reject any quote that lacks line-item scope or that prices “per vent,” a structure that incentivizes minimal effort at each location. CleanRun quotes one flat price per system agreed before work starts, with no additional charges for registers, returns, or photo documentation. Our free estimate includes the on-site inspection and borescope review; you pay nothing if you decline the work. Bring a competitor’s written estimate and we provide a Free Second Opinion with our number next to theirs, no obligation.

Frequently Asked Questions - Air Quality & Sanitizing in Aurora
Air quality and sanitizing targets living or chemical contamination that mechanical cleaning alone does not eliminate, including mold, bacteria, viruses, and odor molecules embedded in duct walls. Standard duct cleaning removes loose debris and dust; sanitizing applies EPA-registered treatments or installs preventive equipment like UV lamps to address the biological or chemical source of symptoms. Call (720) 513-5159 for an inspection that determines which service your system needs.
A typical bacteria sanitizing or odor treatment for a single-system home takes 3-4 hours; mold remediation with full cleaning and clearance documentation may require 6-8 hours or a return visit for severe cases. UV light installation adds 1-2 hours for electrical connection and lux verification. We confirm the expected duration in your written scope so you can plan accordingly.
Most Aurora homeowners pay $400-$650 for sanitizing or odor removal, $800-$1,200 for mold treatment with cleaning, and $800-$1,500 for whole-home air purifier installation including equipment. The exact price depends on system size, contamination extent, and accessibility, which we verify with camera inspection before you commit.
