Alpharetta’s humid subtropical climate creates specific indoor air challenges that generic duct cleaning doesn’t touch. From May through September, relative humidity regularly climbs past 70%, and that moisture collects in ductwork, on evaporator coils, and inside plenums (the main air distribution box above your furnace) where it feeds microbial growth you can’t see until it becomes a smell, a stain, or a respiratory trigger. We’ve treated more than 52,000 homes since 2013, and the pattern in Alpharetta Air Quality & Sanitizing is consistent: newer construction with tighter envelopes traps more recirculated air, and the Chattahoochee River valley’s humidity profile means biological contamination develops faster here than in drier markets. Our crews document every duct run with before-and-after photography, and every treatment is backed by our 365-Day Done Right Promise in writing.

What Our Air Quality & Sanitizing Service Includes

Mold Treatment

Mold in HVAC systems isn’t a surface problem - it’s a colonization problem. In Alpharetta, we regularly find Cladosporium and Aspergillus species establishing at the evaporator coil and in the first 6-10 feet of return ductwork, where temperature differentials create condensation points. Our mold treatment applies EPA-registered antimicrobial agents through negative-pressure extraction equipment (a contained vacuum system that prevents spore release during application) to all affected duct runs, coils, and the plenum. We photograph the colonization before treatment and the cleared surfaces after, with moisture readings taken at multiple points to identify why the mold grew - because killing it without fixing the moisture source means it returns within two seasons.

Bacteria Sanitizing

Bacterial contamination in ductwork doesn’t always produce visible mold, but it produces the musty, sour odor that Alpharetta homeowners notice when the AC first cycles on in spring. We treat bacterial loads with professional-grade sanitizing agents delivered through fogging equipment that reaches the full surface area of rectangular and flex duct alike. The process takes 2-3 hours for a typical 2,400-square-foot home in neighborhoods like Windward or Avalon, and we verify reduction with ATP bioluminescence testing (a swab method that measures living organic matter) where the customer requests documentation. Every bacteria sanitizing job includes the photo record and a written scope showing which duct runs were treated and with what concentration.

Odor Removal

Some odors source to the HVAC system; others source to the home and embed in the ductwork. We distinguish the two before quoting. Cooking oil particulate, pet dander accumulation, and tobacco residue all adsorb to duct surfaces and re-release when heated. Our odor removal process combines mechanical agitation with activated carbon-based treatments and, for severe cases, ozone or hydroxyl generation applied under controlled conditions. In Alpharetta’s newer subdivisions like The Manor or Crooked Creek, we’ve found that spray-foam insulation in tight envelopes can trap volatile organic compounds from flooring and cabinetry, creating a chemical odor profile that standard duct cleaning won’t address. We identify the actual source, document it photographically, and quote only the treatment that matches the chemistry.

UV Light Installation

UV-C light installed at the evaporator coil prevents microbial growth on the wet surfaces where Alpharetta’s humidity feeds it year-round. We size and position UV lamps based on coil dimensions and airflow velocity, not with a one-size-fits-all stick-on unit. Our installations use Honeywell and Abatement Technologies UV systems, with lamp replacement intervals documented in writing - typically 9,000-12,000 hours of operation, or roughly 12-18 months in Alpharetta’s long cooling season. The installation includes a pre-treatment photo of the coil condition and a post-installation photo showing lamp placement and wiring. UV light doesn’t replace duct cleaning, but it extends the interval between cleanings by keeping the coil sterile.

Air Purifier Install

Whole-home air purifiers integrate with the HVAC return, treating all air that passes through the system rather than cleaning a single room. We install Aprilaire and Honeywell whole-home units, with media filters rated at MERV 13-16 depending on the home’s ductwork capacity (higher MERV ratings restrict airflow; we measure static pressure before recommending). For Alpharetta homeowners with allergy sensitivity - common given the area’s heavy pollen loads from oak, pine, and ragweed - we may recommend electronic air cleaners that capture particles down to 0.3 microns. Every installation quote includes the unit, the mounting hardware, electrical connection, and a written performance specification showing expected air changes per hour for your home’s square footage.

Allergen Reduction

Alpharetta’s pollen calendar runs February through November, with oak peaking in March and April, grass in May and June, and ragweed from August to first frost. That pollen enters homes, deposits in ductwork, and recirculates. Our allergen reduction service combines high-efficiency particulate removal from all duct runs with HEPA-filtered negative-pressure extraction during the cleaning process itself - so we’re not blowing settled allergen back into the living space while we work. We photograph the accumulation at the return grille, inside the trunk line, and at selected branch ducts. For homes near the Big Creek Greenway or other wooded areas where outdoor allergen load is highest, we may recommend pairing duct treatment with a whole-home purifier install for sustained reduction.

Brands We Service for Air Quality & Sanitizing

CleanRun technicians are trained on the full equipment roster we carry: Rotobrush mechanical agitation systems for duct interior cleaning, Nikro and Abatement Technologies negative-pressure extractors for contained debris removal, and Honeywell and Aprilaire whole-home purification and UV systems for permanent air quality improvement. We’ve installed hundreds of Honeywell whole-home media air cleaners in Alpharetta’s 2015-2022 construction stock, where the original builder-grade 1-inch filter slot is insufficient for the home’s air volume. Our crews stock Aprilaire replacement media and can verify compatibility with your existing cabinet on the first visit.

We also apply Guardsman antimicrobial treatments in cases where mold or bacterial colonization requires chemical intervention beyond mechanical cleaning. Whether you have a Honeywell electronic air cleaner that needs new cells, an Aprilaire media cabinet that needs upsizing, or any other make of equipment, we can service it, document its condition, and quote any upgrade in writing before work begins. Haven Standard Clause 1 requires that written price; we don’t deviate from it.

Signs You Need Air Quality & Sanitizing Right Now

• Persistent musty odor when the HVAC cycles on. This indicates microbial growth at the coil, in the plenum, or in ductwork with moisture accumulation. The smell is the volatile organic compounds that mold and bacteria release; by the time you smell it, the colony is established. In Alpharetta’s climate, we see this most often in homes with oversized AC units that short-cycle and don’t dehumidify properly.
• Visible mold or discoloration around supply registers. Black, green, or gray spotting on ceiling registers means spores are exiting the ductwork into your breathing space. The register is just where the airflow deposits them; the source is upstream, often at a duct joint with a leak that draws humid attic air.
• Increasing allergy symptoms indoors, especially at night. If you’re symptomatic in your Alpharetta home but fine elsewhere, the HVAC system is the likely vector. Pollen and dust mite debris accumulate in ductwork and release in concentrated pulses when the blower activates. We verify this with pre-treatment air sampling on request.
• Recent water intrusion or condensation leak. Any past leak - a clogged condensate drain, a frozen coil that thawed, a roof leak near a duct chase - creates the moisture reservoir that mold requires. Even if the leak was “fixed,” the duct interior may still harbor contamination that standard drying didn’t reach.
• Home purchase within the last 12 months with no duct documentation. Alpharetta’s resale market moves fast, and inspection reports rarely include duct interior photography. If you don’t have a documented photo record of what was inside your ductwork when you bought the home, you don’t know what you’re breathing. We provide that record as a standard deliverable.

Our Air Quality & Sanitizing Process - Step by Step

1. 1
   On-site assessment and moisture mapping. We arrive at your Alpharetta home with a written appointment window, technician name, and photo ID confirmed by text. The technician inspects accessible ductwork, the evaporator coil, and the plenum with a borescope camera (a flexible video probe that records 1080p footage inside ducts). We take humidity readings at the return and supply, and identify any moisture sources - duct leaks, insulation gaps, or drainage issues - that would undermine treatment results.
2. 2
   Written scope and price delivered before work starts. Haven Standard Clause 1: you receive a written price for the exact treatment recommended, with line-item breakdown by service area or equipment type. No verbal estimates, no “we’ll see how long it takes” pricing. You approve in writing before we open a panel or start equipment.
3. 3
   Contained treatment with negative-pressure extraction. For sanitizing and mold treatment, we seal registers and establish negative pressure at the trunk line, preventing chemical or particulate release into the home. Mechanical agitation loosens debris; extraction removes it. For UV or purifier installation, we power down the system, verify electrical capacity, and mount equipment per manufacturer specification.
4. 4
   Photographic documentation of every treated duct run. The borescope captures before-and-after images of each branch duct, the plenum, and the coil. These images are delivered as part of your job record, not held hostage or offered as an upsell. You see what was there and what remains after treatment.
5. 5
   System restart, performance verification, and written warranty. We restore power, verify airflow at all registers, and confirm proper operation of any installed equipment. The 365-Day Done Right Promise is issued in writing, along with maintenance recommendations specific to your home’s conditions - for Alpharetta, that typically includes coil inspection timing before the May humidity surge.
