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.

AfterTrusted Air Quality & Sanitizing for Cumming Homeowners
Air quality and sanitizing service in Cumming typically addresses mold, bacteria, allergens, and persistent odors inside your ductwork and HVAC system, with whole-home treatments running $450-$1,200 depending on scope and method. Since 2013, CleanRun Duct Repair & Cleaning has delivered documented photo records of every duct run we’ve treated in Forsyth County, from Vickery Village to the Polo Fields, and we back every job with our 365-Day Done Right Promise in writing. Call (678) 693-5322 for a written price before any work starts - no exceptions, no per-vent add-ons, no surprises when the truck leaves your driveway.
Homeowners in Cumming’s 2015-2025 builds, especially those near Lake Lanier’s humidity corridor, regularly find microbial growth in their plenum - the central distribution box where all duct runs connect - that standard vacuum cleaning won’t address. We’ve photographed active mold in the first elbow of supply runs in homes as new as three years old in the Brookwood and Kelly Mill districts. The issue isn’t age; it’s that Georgia’s mixed-humidity climate creates condensation points inside metal ductwork that spore growth exploits. Our our Air Quality & Sanitizing in Cumming treats the source, not the symptom, and every customer receives the before-and-after photo record to verify what was found and what was done.
What Our Air Quality & Sanitizing Service Includes
Mold Treatment
Mold treatment targets active fungal growth inside duct runs, the plenum, and evaporator coil housing - not surface wiping of visible spots on ceiling tiles. In Cumming, we regularly find Cladosporium and Aspergillus species colonizing the first 18 inches of supply ducts where cold air meets warm attic temperatures, particularly in homes north of Bethelview Road with sealed crawl spaces. Our process applies an EPA-registered antimicrobial through the full negative-pressure extraction system, reaching past what any hand wipe can access, and we photograph the treated surface with a borescope camera to document kill-site contact. The written scope specifies which runs were treated, with what concentration, and the re-inspection interval if warranted.
Bacteria Sanitizing
Bacteria sanitizing addresses microbial loads that standard duct cleaning dislodges but does not neutralize - think of it as the difference between sweeping a floor and disinfecting it. We see elevated bacterial counts in Cumming homes with pets, multiple children, or recent water intrusion events, particularly in the South Forsyth and Shiloh Road corridors where seasonal lake-effect humidity spikes. Our application uses professional-grade fogging equipment to deliver the sanitizing agent as a particle small enough to follow the air stream through the entire duct network, including behind dampers and through register boots. The photo record shows the fog density at each register, confirming distribution where it matters.
Odor Removal
Odor removal eliminates persistent smells that originate inside the HVAC system rather than in the conditioned space - the musty “wet sock” note at startup, the pet-urine phantom that returns after surface cleaning, or the organic decay smell from a rodent intrusion in a return chase. We’ve traced odor sources to dead insects packed in the plenum of Cumming homes near agricultural zones, and to bacterial biofilms on evaporator coils that standard coil cleaning misses. Our process pairs source removal with oxidizing treatment, and we run the system post-treatment to verify the smell is gone before we pack equipment - documented in the job record with time-stamped photos.
UV Light Installation
UV light installation places a germicidal lamp in the supply plenum or above the evaporator coil, where it irradiates passing air and irradiates surfaces that stay wet during cooling cycles. In Cumming’s climate, coils stay damp from May through October; that’s six months of optimal bacterial and mold growth conditions. We size the lamp to the plenum volume and specify the replacement bulb interval in writing - typically 9,000 hours, or about 12 months of continuous operation. The installation includes a sight-glass port so you can verify lamp operation without disassembling anything, and we photograph the mounting position to document that the UV-C output actually intersects the air stream, not just the housing wall.
Air Purifier Install
Whole-home air purifier installation integrates with your existing HVAC blower, treating all conditioned air rather than the single-room coverage of portable units. We specify Abatement Technologies and Honeywell media-based systems for Cumming homes with allergen-sensitive occupants, and electronic precipitator options where particle load is extreme - near construction zones or unpaved roads in the more rural Forsyth addresses. Every install includes a written pressure-drop calculation to ensure the added resistance doesn’t strain your blower motor, and we record the pre- and post-install static pressure readings in your job file. The filter replacement schedule is specified in writing, with part numbers, so you’re not guessing what to buy in 12 months.
Allergen Reduction
Allergen reduction combines mechanical filtration, source removal, and surface treatment to lower the total load of pollen, pet dander, dust mite debris, and mold spores circulating through your home. Cumming’s spring oak and pine pollen counts regularly exceed 3,000 grains per cubic meter, and that load deposits in ductwork over years of accumulation. We measure the depth of debris at multiple points in the system with a borescope, remove it through negative-pressure extraction, then treat remaining surfaces to reduce adhesive residue that traps new particles. The photo record shows the debris depth measurement and the post-cleaning surface condition - not marketing images, your actual ducts.

Brands We Service for Air Quality & Sanitizing
Our equipment roster includes Rotobrush, Nikro, and Abatement Technologies - brands we’ve worked with since 2013 and that any customer can research independently. We’ve run Rotobrush contact-vacuum systems on hundreds of Cumming homes with flexible ductwork, where aggressive air-whip methods risk damage, and we maintain the brush inventory to match duct diameters from 4-inch dryer vents to 14-inch main trunks. Nikro’s negative-pressure extractors power our source-removal phase; we specify the HEPA filtration level and airflow rate in your written scope, so you know the captured debris isn’t exhausting back into your home. Abatement Technologies supplies our containment and filtration accessories for occupied-home work, including the portable air scrubbers we deploy in bedrooms during treatment.
We also install and service Honeywell, Aprilaire, and Guardsman air quality components - media filters, electronic air cleaners, and UV-C systems - and stock the replacement elements so you’re not waiting on shipping when a bulb burns out or a filter loads up. Whether your system is one of these brands or any other make, we can specify compatible treatment and document the integration in writing before work starts. Haven Standard Clause 1: Written Price Before Any Work Starts applies to every brand consultation - no “call for compatibility” runaround.
BeforeAfterSigns You Need Air Quality & Sanitizing Right Now
- Persistent musty smell at system startup. The odor that hits when the blower first engages is almost always microbial growth on the evaporator coil or in the plenum, where condensation accumulates during the off cycle. In Cumming’s humidity, this condition can develop in as little as two seasons of operation, and it won’t resolve with standard filter changes or duct cleaning alone.
- Visible mold on registers or in return grilles. What you can see on the surface typically represents a fraction of the colonized area; the duct run behind that register is likely hosting growth that spore-loads the entire home every time the system cycles. We photograph the visible indicator and trace it to the source with a borescope before quoting any work.
- Increasing allergy symptoms despite medication changes. When occupants experience worsening congestion, eye irritation, or respiratory symptoms specifically at home, the HVAC system is the common-denominator exposure source. We’ve documented 10x spore count reductions post-treatment in Cumming homes where occupants had accepted their symptoms as “just Georgia allergies.”
- Recent water intrusion or leak repair. Any event that introduced moisture to the duct system - roof leak, condensate overflow, foundation seepage - creates conditions for mold growth within 48-72 hours. Even if the leak was repaired promptly, the interior duct surfaces may not have dried before spores established. We inspect these scenarios with moisture-mapping tools and specify treatment only where it’s actually needed.
- Family member with compromised immune system. Infants, elderly occupants, and immunocompromised individuals face elevated risk from environmental mold and bacterial loads that healthy adults tolerate without symptoms. Our sanitizing protocols for these households include extended contact-time applications and post-treatment air sampling documentation, with the parameters specified in writing before work begins.
Our Air Quality & Sanitizing Process - Step by Step
- 1
System inspection and photo documentation. We access the plenum, evaporator housing, and representative supply and return runs with a borescope camera, recording the condition we find - debris depth, visible growth, moisture indicators, and any mechanical damage. These images become the “before” record in your job file, and we review them with you before quoting any work.
- 2
Written scope and fixed-price quote. Based on the inspection, we specify the treatment methods, the areas to be addressed, the products and concentrations to be used, and the total price - one flat figure per system, no per-vent add-ons, no open-ended “time and materials” structure. Haven Standard Clause 1 requires your written approval before any panel comes off or any chemical is mixed.
- 3
Source removal and mechanical cleaning. Where debris or growth is present, we remove it through negative-pressure extraction - the duct run is placed under vacuum while agitation tools dislodge material, capturing it in a HEPA-filtered collector rather than redistributing it. We photograph the cleaned surface before applying any treatment agent, so the photo record shows both what was there and what was removed.
- 4
Application of treatment agent. The specified antimicrobial, sanitizer, or oxidizer is applied at the concentration and contact time warranted by the target organism - mold spores require different protocols than bacterial biofilms or odor molecules. We record the application method (fog, spray, or integrated with extraction), the coverage verification, and any safety interval before the system is returned to service.
- 5
Post-treatment verification and documentation. The system is run through a complete cycle, we verify no residual odor or visible treatment residue, and we capture the “after” photos for every treated run. Your deliverable includes the written scope, the before-and-after photo record, the product safety data sheets, and the 365-Day Done Right Promise - all in writing, all before we leave.
How Much Does Air Quality & Sanitizing Cost in Cumming?
A typical mold treatment for a single-family home in Cumming runs $650-$1,100 depending on the number of affected duct runs, the accessibility of the plenum, and whether the evaporator coil requires separate handling. For full Air Quality & Sanitizing pricing across all our services, see our detailed cost guide. Bacteria sanitizing and odor removal, often paired together, typically fall in the $450-$750 range for whole-system application. UV light installation with a properly sized germicidal lamp and sight-glass port runs $380-$620, while whole-home air purifier installation ranges from $890-$1,850 depending on the unit capacity and any duct modifications needed for proper airflow. Allergen reduction as a standalone service, when paired with duct cleaning, typically adds $280-$450 to the base cleaning price.
Several factors move these ranges. Homes with hardboard ductwork or sealed crawl spaces in the Windermere and Brannon Oak Farm areas often require additional access points, which we specify in the written scope with their individual costs. The age of the HVAC system matters less than its configuration - a zoned system with multiple plenums multiplies the treatment areas, and we quote each zone separately so you see exactly what drives the total. Seasonal demand in Cumming peaks in March-April and September-October, but we don’t surge-price; the written price you receive is valid for 30 days regardless of when you schedule.
The most common overpayment we see is homeowners accepting a low duct-cleaning coupon, then facing pressure-adds for “sanitizing” at inflated per-vent rates once the crew is inside. CleanRun doesn’t operate this way. The price we write is the price you pay - one flat figure per system, agreed before work starts, with every included service itemized. If you’ve received a competitor’s written estimate, bring it; Haven Standard Clause 7 provides a Free Second Opinion, and we’ll put our number next to theirs so you can compare line for line.
Every estimate includes the full photo record deliverable, the 365-Day Done Right Promise, and the product specification sheet for any treatment agent used. Call (678) 693-5322 for a written quote - estimates are free, and you’ll have the full scope in hand before any commitment.

Frequently Asked Questions - Air Quality & Sanitizing in Cumming
Alpharetta Air Quality & Sanitizing targets the same living contaminants - mold, bacteria, viruses, and odor-causing organic compounds - that mechanical removal alone doesn’t neutralize, while standard duct cleaning removes particulate debris like dust and construction residue. In Cumming’s humid climate, we’ve found that ducts cleaned without sanitizing treatment often show new microbial growth within 18 months, particularly in homes with sealed crawl spaces that limit natural ventilation. Our service pairs source removal with EPA-registered treatment agents, documented with before-and-after photos of the actual surfaces in your system.
A typical whole-home treatment takes 3-5 hours from arrival to final system test, with mold remediation in extensive systems extending to a full day. We specify the expected duration in your written scope so you can plan accordingly - no “we’ll be done when we’re done” scheduling. The system can typically be returned to normal operation within 2 hours of treatment completion, with any extended ventilation interval noted on your job record.
Most Cumming homeowners pay between $450 and $1,200 for complete air quality and sanitizing service, with the specific figure depending on system size, contamination type, and whether integrated components like the evaporator coil require separate handling. We also offer Air Quality & Sanitizing - Canton with the same flat-rate pricing structure. We provide one flat price per system in writing before work starts - no per-vent pricing, no post-arrival add-ons, no exceptions. Call (678) 693-5322 for an exact quote; estimates are free and valid for 30 days.
Yes - we install, service, and stock replacement components for Honeywell, Aprilaire, Guardsman, and other major brands, and we specify compatibility in writing before any purchase. Our equipment roster also includes Abatement Technologies and Rotobrush systems for treatment application, with brand names and model numbers documented in your job record for independent verification. If you have a brand not listed here, we research compatibility and document our findings before quoting.
Active mold growth in occupied sleeping areas or HVAC systems serving immunocompromised occupants warrants prompt scheduling, but air quality and sanitizing is fundamentally a planned maintenance service rather than an emergency dispatch. We don’t promise same-day arrival because proper treatment requires inspection, written scope development, and material preparation that rushed scheduling compromises. For documented urgent conditions, we typically schedule within 48 hours in the Cumming area.
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 job record, not as a policy subject to manager discretion. For mold treatment specifically, we specify the re-inspection interval and conditions in your scope; if regrowth occurs at treated sites within the promise period due to application failure, we retreat at no charge. Haven Standard Clause 6: Accountable Workmanship requires this commitment in writing, not just in marketing copy.
Clear a 3-foot access path to the indoor HVAC unit, the main return grille, and at least one supply register per floor; remove pets from the work area for the duration; and have your most recent filter purchase information available so we can verify compatibility. We don’t require you to cover furniture or vacate the home - our containment and negative-pressure protocols manage discharge - but we do ask that occupants with respiratory sensitivities remain out of the immediate work zone during chemical application. The written scope includes any home-specific preparation notes we identify during scheduling.
