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 Marietta Homeowners
Air Quality & Sanitizing pricing in Marietta typically addresses mold, bacteria, allergens, and odors inside your ductwork and HVAC system, with whole-home treatments running $450-$1,200 depending on scope and method. CleanRun Duct Repair & Cleaning has delivered documented results in Marietta since 2013, with every job starting from a written price and ending with before-and-after photos of every duct run. Call (470) 516-9337 for a free estimate with no obligation to book.
We’ve worked in Marietta homes long enough to recognize the patterns, and we also provide Air Quality & Sanitizing in Marietta. The humidity that hangs over Cobb County from May through October creates conditions inside ductwork that dry climates simply don’t produce. We’ve photographed mold growth on evaporator coils in East Cobb homes where the thermostat never dropped below 72, and we’ve documented bacterial buildup in return plenums (the central collection box for air before it reaches your HVAC unit) in newer subdivisions near Kennesaw Mountain where construction dust sat undisturbed for months before move-in. Our crews carry Nikro and Abatement Technologies equipment specifically because these tools allow negative-pressure extraction (contained vacuum removal that prevents cross-contamination) during sanitizing work. Every technician is background-checked, uniformed, and identified by name before arrival under Haven Standard Clause 3: Verified Crews.
What Our Air Quality & Sanitizing Service Includes
Mold Treatment
Mold inside your HVAC system spreads through airborne spores that recirculate every time the blower engages. In Marietta, we regularly find mold at the evaporator coil and in the first few feet of supply ductwork, where condensation collects during our humid summers. CleanRun treats mold with EPA-registered products applied after mechanical removal of visible growth, then verifies results with post-treatment photos of every affected duct run. We don’t cover mold; we remove it and document the difference.

Bacteria Sanitizing
Bacterial contamination in ductwork often follows water intrusion or prolonged high humidity, producing musty odors that don’t respond to standard cleaning. Our bacteria sanitizing service applies commercial-grade antimicrobial agents to the full interior surface of your duct system, not just the registers (the visible grilles where air enters your rooms) you can reach with household tools. We use Honeywell-compatible application equipment calibrated to manufacturer specifications, and we photograph every treated section so you can verify coverage.

Odor Removal
Lingering odors from pets, smoke, or previous water damage embed in porous duct liner and recirculate until the source is neutralized, not masked. Our odor removal process in Marietta combines source elimination through contact cleaning with targeted treatment of absorbent materials in the plenum and trunk lines (the main distribution channels that branch to individual rooms). We’ve resolved odor issues in homes near the Marietta Square where previous companies had only sprayed deodorizer through the registers.

UV Light Installation
UV-C light installed at the evaporator coil or in the return ductwork prevents mold and bacterial growth by disrupting DNA replication at the cellular level. We size and position UV systems based on your coil dimensions and airflow rate, using Aprilaire and Honeywell units sized to manufacturer CFM (cubic feet per minute) specifications. In Marietta’s climate, UV lights typically require annual bulb replacement, and we include this maintenance schedule in your written job record.

Air Purifier Install
Whole-home air purifiers integrate with your existing HVAC system to filter or neutralize particles, gases, and biological contaminants at the central unit rather than relying on portable room units. We install Honeywell and Aprilaire whole-home systems matched to your ductwork capacity, with written performance specifications before work begins. For Marietta homeowners with allergy sensitivities, we specify MERV rating (Minimum Efficiency Reporting Value, the standard measure of filter performance) and expected pressure drop so you understand the trade-off between filtration and system airflow.

Allergen Reduction
Allergen reduction targets the particulate matter that triggers respiratory symptoms: pollen, pet dander, dust mite debris, and mold spores that accumulate in ductwork and redistribute through your home. Our process combines mechanical agitation with negative-pressure extraction, followed by surface treatment of the duct interior. In Marietta’s spring pollen season, we’ve measured significant particulate loads in homes near Kennesaw Air Quality & Sanitizing service areas around Kennesaw Mountain National Battlefield Park, where oak and pine pollen enter through intake vents and settle in the system.

Brands We Service for Air Quality & Sanitizing

We’ve installed and serviced hundreds of Honeywell whole-home air purifiers and UV systems in Cobb County, and we stock replacement bulbs and filters for their most common residential models. Our technicians carry the installation manuals for Honeywell F100, F200, and F300 series media air cleaners, and we verify airflow specs with a manometer (a precision pressure gauge) before signing off on any install. We’ve also worked extensively with Aprilaire whole-home purifiers, particularly the Model 5000 electronic air cleaner, and we understand the maintenance intervals and indicator light sequences that tell you when service is due.
Whether you have Honeywell, Aprilaire, or any other make of air quality equipment in your Marietta home, we can service it, repair it, or replace it with a written scope and price before any work starts. Our equipment roster also includes Nikro and Abatement Technologies for duct-access work, and we apply Guardsman products where manufacturer specifications call for them. If you’re unsure what system you have, we’ll identify it during your free estimate and explain your options in writing.
Before
AfterSigns You Need Air Quality & Sanitizing Right Now
- Musty or sour odors when the HVAC cycles on. Odors that intensify when your system starts usually indicate biological growth inside the ductwork or on the evaporator coil, not just normal household smells. In Marietta’s humidity, we’ve found active mold within 48 hours of a homeowner first noticing this symptom.
- Allergy symptoms that worsen at home and improve when you leave. If your congestion, sneezing, or itchy eyes spike within an hour of arriving home, your HVAC system may be distributing concentrated allergens from inside the ductwork. We’ve documented this pattern in homes near the Chattahoochee River corridor where outdoor pollen combines with indoor mold spores.
- Visible mold or discoloration around registers or on the evaporator coil access panel. Surface growth you can see almost always indicates more extensive colonization inside the system, where dark, damp conditions persist. We photograph these areas during our initial inspection and show you the full extent before proposing treatment.
- Recent water damage or condensation issues in your home. Even resolved leaks leave residual moisture in duct liner and insulation that supports bacterial growth for months. Our camera inspections in Marietta homes often find water stains and active microbial growth in ductwork above finished basements and crawl spaces.
- Unexplained respiratory issues in household members with no prior history. New or worsening breathing problems, particularly in children or elderly residents, can signal elevated biological contamination in your indoor air. We don’t diagnose health conditions, but we can measure and document what’s circulating through your system.
Our Air Quality & Sanitizing Process - Step by Step

- 1
Written estimate with scope and price. We inspect your ductwork with a borescope camera (a flexible optical tool that transmits video from inside the ducts) and document what we find. You receive a written price for the complete job before we begin, with no per-vent add-ons or surprise charges. Haven Standard Clause 1 requires this; we don’t deviate.
- 2
Containment and protection of your home. We seal registers, protect flooring, and establish negative pressure at the work zone to prevent contamination of living spaces during treatment. Our Nikro equipment maintains controlled airflow direction throughout the process.
- 3
Mechanical removal of visible contamination. We agitate and extract debris, mold, and biofilm from duct surfaces using contact methods that reach the full interior perimeter of each duct run, not just the centerline where vacuum hoses naturally travel.
- 4
Application of treatment agents. We apply EPA-registered sanitizers or install specified equipment according to manufacturer guidelines, with calibrated equipment and documented coverage. Every treated section is photographed before and after.
- 5
Verification and documentation delivery. You receive your Documented Photo Record showing the interior of every duct run, plus the written scope of work and your 365-Day Done Right Promise. We review the photos with you and explain any recommendations for ongoing maintenance.
How Much Does Air Quality & Sanitizing Cost in Marietta?
A typical bacteria sanitizing or odor removal treatment for a single HVAC system in Marietta runs $450-$750, depending on the number of duct runs, the severity of contamination, and whether the evaporator coil requires separate access and treatment, similar to our Air Quality & Sanitizing in Smyrna. Mold treatment with full mechanical removal and post-treatment verification typically ranges from $650-$1,200 for residential systems in the 1,500-3,500 square foot range common in East Cobb and West Cobb subdivisions. UV light installation with a properly sized unit and electrical connection runs $400-$800 per light location, while whole-home air purifier installation ranges from $850-$1,800 depending on the unit capacity and any required duct modifications.
Several factors move these prices within the range. Homes with more than one HVAC zone require separate treatment of each system. Ductwork with internal insulation liner takes longer to treat properly than bare metal ducts. Access issues, such as systems in tight attic spaces common in Marietta’s older neighborhoods near the Square, add labor time. And the extent of visible contamination documented during our camera inspection directly affects the scope of mechanical removal required before sanitizing agents can be effective.
To avoid overpaying, reject any quote that doesn’t specify what’s included in writing. The $79 coupon model in this industry typically covers a brief vacuum of accessible register areas, not full-system treatment. Ask whether the price includes before-and-after documentation of every duct run, whether the evaporator coil is included, and what product or equipment will be used. CleanRun provides all of this in writing before you decide, and we offer a Free Second Opinion on any competitor’s written estimate.
