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 Chicago Homeowners
Air Quality & Sanitizing - Chicago addresses mold, bacteria, odors, and airborne contaminants that standard duct cleaning leaves behind. Most homeowners in Chicago’s lake-effect humidity zones discover they need this only after a musty smell persists or a family member’s allergies worsen indoors. Since 2013, CleanRun Duct Repair & Cleaning has treated more than 52,000 homes with a written price delivered before any work starts and a documented photo record of every duct run included as standard. Our crews serve Lincoln Park to Bronzeville, Logan Square to Hyde Park, with background-checked, uniformed technicians who identify themselves by name before arrival. Call (708) 683-3974 for a free estimate with no obligation.
Chicago’s older housing stock, combined with seasonal humidity swings from Lake Michigan, creates conditions where microbial growth in ductwork outpaces what vacuum extraction alone can address. We’ve photographed active mold colonies in Hyde Park greystones, bacterial biofilm in Wicker Park rehabbed lofts, and odor reservoirs in Lincoln Park single-family homes that previous cleanings only redistributed. Our approach treats the source, documents the result, and backs the work with the 365-Day Done Right Promise in writing on every job.
What Our Air Quality & Sanitizing Service Includes
Mold Treatment
Mold treatment targets active fungal growth inside duct runs, the plenum (the central distribution box where heated or cooled air mixes before branching out), and on HVAC components where moisture accumulates. In Chicago, we regularly find Cladosporium and Penicillium species thriving at the first elbow downstream of evaporator coils, especially in homes near the lake where summer humidity stays elevated through September. CleanRun applies EPA-registered antimicrobial agents with controlled application equipment, then verifies elimination through post-treatment photography included in your documented photo record. We do not paint over mold or treat only accessible surfaces; every treated run is photographed before and after, with images delivered as part of the standard job record.

Bacteria Sanitizing
Bacteria sanitizing addresses microbial contamination that produces odors, contributes to biofilm formation, and can circulate endotoxins through your ventilation system. Chicago homeowners often notice this problem after water damage, during shoulder seasons when systems cycle infrequently, or in homes with pets where dander provides a nutrient source. CleanRun uses professional-grade application equipment from Abatement Technologies to distribute sanitizing agents throughout the entire duct network, not just at registers (the visible grilles where air enters rooms). The treatment reaches the return plenum and main trunk lines where bacterial loads typically concentrate. Your written scope specifies which agents are used, their EPA registration numbers, and the contact time achieved.

Odor Removal
Odor removal eliminates persistent smells that originate within the HVAC system rather than from temporary sources like cooking or pets. In Chicago’s Portage Park and Irving Park neighborhoods, we’ve traced stubborn odors to decomposing organic matter in floor cavities that communicated with ductwork through compromised seams, or to previous rodent activity in basements with fiberglass-lined ducts. CleanRun’s process identifies the source through camera inspection and negative-pressure extraction testing, then applies targeted treatments rather than masking agents. The documented photo record shows the source location, the treatment application, and post-verification imagery so you can see the difference between covering an odor and removing its cause.

UV Light Installation
UV light installation places germicidal ultraviolet lamps at strategic points in your HVAC system, typically at the evaporator coil and in the return plenum, to inhibit microbial growth on wet surfaces and in moving air. Chicago’s cooling season runs long enough that coil fouling is nearly universal in homes without UV protection; we’ve measured pressure drops increase 15-30% in systems with heavily fouled coils. CleanRun specifies Honeywell or Aprilaire UV systems based on your duct configuration and coil geometry, with lamp intensity matched to the plenum volume and airflow rate. Installation includes written specifications for lamp replacement intervals, typically 12-18 months for standard-output lamps, with replacement scheduling available through our office.

Air Purifier Install
Air purifier install refers to whole-house filtration and purification equipment integrated at the air handler, treating all air circulated through your duct system rather than cleaning single rooms. For Chicago’s pollen seasons, which run from March tree pollen through October ragweed, plus year-round urban particulate from traffic and construction, whole-house systems provide consistent treatment without the noise and space demands of portable units. CleanRun installs Honeywell and Aprilaire electronic and media air cleaners with MERV ratings and clean air delivery rates appropriate to your home’s square footage and the local particulate load. Every installation quote includes the written price for the unit, electrical connection if required, and integration with your existing ductwork before any work begins.

Allergen Reduction
Allergen reduction combines mechanical filtration, source removal, and surface treatment to lower concentrations of dust mite debris, pet dander, pollen, and mold spores in your ventilation system. In Chicago’s North Shore-facing neighborhoods like Rogers Park and Edgewater, where lake breezes deposit pollen and urban dust, we regularly measure high particulate loads in return ducts during initial inspections. CleanRun’s process begins with negative-pressure extraction (a controlled vacuum system that draws debris out while preventing it from entering your living space) of all duct runs, followed by targeted treatment of reservoirs where allergens accumulate, and concludes with recommendations for ongoing filtration. The documented photo record shows particulate depth at key locations before and after extraction.

Brands We Service for Air Quality & Sanitizing

CleanRun works with professional-grade equipment from manufacturers whose specifications are published and verifiable. We’ve installed and serviced hundreds of Honeywell whole-house air cleaners and UV systems, stocking replacement media and lamps for their F100, F200, and UV2400 series so Chicago homeowners aren’t left waiting for special orders. Our technicians carry Honeywell specification sheets on tablets, so you can compare rated clean air delivery rates and MERV performance against your home’s requirements before agreeing to any installation.
We also specify Aprilaire media air cleaners and UV systems, particularly their Model 5000 electronic air cleaner and 1900 series whole-house purifiers, which we’ve found well-suited to the particle loads common in Chicago’s urban and near-suburban environments. Whether you have Honeywell, Aprilaire, or any other make of air quality equipment, we can service, repair, or replace it with a written price delivered before work starts. Our equipment roster also includes Rotobrush mechanical cleaning systems and Nikro negative-pressure extractors for the source-removal phase of allergen reduction treatments.

AfterSigns You Need Air Quality & Sanitizing Right Now
- Musty or earthy odors when the HVAC system cycles on. This typically indicates active microbial growth in the plenum or duct runs, not just surface dust. In Chicago’s humidity, we’ve seen mold colonies establish in as little as one season of inadequate dehumidification, especially in basement and first-floor ducts where ground moisture contributes.
- Allergy symptoms that worsen indoors or improve when you leave home. If antihistamines help less in your living room than they do outdoors, your ductwork may be circulating concentrated allergen loads. We measure this regularly in homes near the Kennedy and Edens corridors, where outdoor particulate combines with indoor sources.
- Visible mold or staining around registers or on the air handler. Surface growth at registers often indicates more extensive colonization upstream, where the duct run stays dark and humid. CleanRun’s camera inspection can verify extent without dismantling finished spaces.
- Recent water damage or flooding that affected ductwork or the HVAC system. Even professionally dried homes often retain moisture in duct insulation and low points of the system. Bacterial and mold growth can begin within 48-72 hours of water intrusion.
- Persistent odors that return after standard duct cleaning. If a previous cleaning reduced dust but left smells intact, the source is likely microbial or chemical, not particulate. Sanitizing treatment addresses what vacuum extraction cannot remove.
Our Air Quality & Sanitizing Process - Step by Step

- 1
Written estimate with scope and price. Every job begins with a free inspection and a written price delivered before any work starts, under Haven Standard Clause 1. The scope specifies which treatments apply to which duct runs, what equipment will be used, and what documentation you’ll receive. No verbal estimates, no “we’ll see once we’re in there” pricing.
- 2
Pre-treatment photo documentation. Our technicians photograph the inside of every duct run, the plenum, and accessible HVAC components with borescope cameras. These images establish baseline conditions and identify hidden problems, like mold behind register boots or debris accumulation at duct elbows, that aren’t visible from the living space.
- 3
Source removal and mechanical cleaning. We use Rotobrush contact cleaning and Nikro negative-pressure extraction to remove particulate, biofilm precursors, and debris that would otherwise shield microbes from treatment agents. This step is essential; applying sanitizers over heavy debris wastes product and leaves living colonies intact.
- 4
Targeted treatment application. Based on findings, we apply EPA-registered antimicrobial agents, install UV lamps, or integrate air purification equipment as specified in your written scope. Application equipment is selected for your duct material, whether galvanized steel, flex duct, or fiberboard, to achieve proper coverage without damage.
- 5
Post-treatment verification and documentation. Every treated run is photographed after completion. The documented photo record, including before images, after images, and the written scope with pricing, is delivered as a standard deliverable. The 365-Day Done Right Promise is included in writing on every job.
How Much Does Air Quality & Sanitizing Cost in Chicago?
Air Quality & Sanitizing pricing for a typical mold treatment in a single-family Chicago home runs $450-$850 depending on the number of affected duct runs, whether the plenum requires treatment, and whether HVAC components like the evaporator coil need cleaning. Bacteria sanitizing for a complete system typically falls between $350 and $650. UV light installation, including the lamp assembly, mounting, and electrical connection, generally ranges from $400 to $900 per lamp location, with most Chicago homes requiring one or two lamps for effective coverage. Whole-house air purifier installation varies more widely, from $600 for a media cleaner in an accessible return duct to $1,800-$2,400 for electronic air cleaners with integrated controls in complex systems. Allergen reduction as a standalone service, combining deep extraction with surface treatment, typically runs $500-$950 for homes under 3,500 square feet.
Several factors move prices within these ranges. Homes in Chicago’s historic districts, like parts of Old Town or the Near South Side, often have limited access panels or original ductwork that requires more time to treat properly. Multiple HVAC zones add duct runs and plenum complexity. Equipment accessibility, whether the air handler is in a cramped crawl space or an open basement, affects labor time. We specify all of this in your written estimate before work begins, so the price you agree to is the price you pay.
To avoid overpaying, request that any quote specify the exact number of duct runs to be treated, the products or equipment to be installed with manufacturer model numbers, and whether post-treatment verification is included. CleanRun’s estimates include all three by default. We also offer a Free Second Opinion on any written estimate from another company; bring their quote and we’ll put our number next to it in writing, with no obligation to use our service.
Every estimate is free and includes the inspection, camera documentation of conditions found, and a written scope with fixed pricing. Call (708) 683-3974 to schedule.

Frequently Asked Questions - Air Quality & Sanitizing in Chicago

Air Quality & Sanitizing in Oak Lawn treats microbial contamination, odors, and airborne pollutants that mechanical cleaning alone cannot remove, while standard duct cleaning removes particulate debris through vacuum extraction. Duct cleaning addresses what you can see and weigh; sanitizing addresses living organisms and chemical residues that persist on duct surfaces. In Chicago’s humid climate, we find that roughly 30% of homes that have had standard cleaning still need sanitizing to resolve odor or health complaints.
A typical residential treatment takes three to five hours for a single-system home, with larger homes or those with multiple HVAC zones requiring a full day. Mold treatment adds time for proper contact and drying periods; UV installation requires electrical work that we schedule with adequate time for safe completion. Your written estimate specifies the expected duration before you confirm the appointment.
Most homeowners in Skokie pay for Air Quality & Sanitizing treatments between $350 and $950, with UV installation or whole-house air purifiers adding $400-$2,400 depending on equipment selection. The exact price depends on system size, contamination extent, and accessibility, all of which we assess during the free inspection and specify in writing before work begins. Call (708) 683-3974 for an exact quote; estimates are free.
