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 Johns Creek Homeowners
Air quality and sanitizing service in Johns Creek typically addresses mold, bacteria, allergens, and persistent odors inside your HVAC system, with most jobs completed in a single scheduled visit and priced in writing before work begins. For homeowners in Johns Creek, where humid summers and tight, energy-efficient construction trap contaminants inside ductwork, this service is often the difference between a system that circulates filtered air and one that redistributes what grew in the plenum over the winter.
We’ve been working in Johns Creek since 2013, and the pattern we document most often is this: a home built between 2015 and 2020, excellent insulation, high-efficiency HVAC, and a family wondering why the air still smells stale or why allergy symptoms spike when the system cycles on. The camera usually shows the answer - microbial growth at the evaporator coil, debris accumulation in the return duct, or biofilm on the duct walls that standard filter changes never reach. Every job we complete includes a written price agreed before any panel comes off, a Documented Photo Record of every duct run showing what we found and what we left behind, and the 365-Day Done Right Promise backed in writing. Call (470) 326-1926 for a free estimate with no obligation to proceed.
What Our Air Quality & Sanitizing Service Includes
Mold Treatment
Mold treatment targets active fungal growth inside ductwork, on the evaporator coil, or within the plenum - the large central chamber where conditioned air mixes before entering individual duct runs. In Johns Creek, we treat this most often in homes near the Chattahoochee River corridor or in subdivisions with mature tree canopy where exterior moisture loads stay elevated from April through October. Our Air Quality & Sanitizing - Lawrenceville teams encounter comparable moisture issues in homes near the Yellow River basin. Our crews apply EPA-registered antimicrobial agents through controlled fogging or direct application, depending on what the photo record reveals, and we verify treatment coverage with post-application imaging under the 365-Day Done Right Promise.
Bacteria Sanitizing
Bacteria sanitizing eliminates microbial colonies that standard cleaning dislodges but does not kill, particularly on porous fiberglass duct board common in Johns Creek homes built during the 2015-2019 construction boom. You’ll know this is needed when musty odors persist after a standard duct cleaning or when a household member has recurring respiratory irritation without an identified allergen. We use professional-grade application equipment from Abatement Technologies with hospital-grade sanitizers, and the treatment is documented in your photo record with before-and-after images of the treated surfaces.
Odor Removal
Odor removal addresses persistent smells that originate inside the HVAC system rather than in the living space - the difference between a candle solution and a source solution. In Johns Creek, we most commonly trace these to pet dander accumulation in return ducts, tobacco residue on coil fins, or organic decay in condensate pans that drains incompletely during high-humidity months. Our process identifies the source through systematic inspection, treats it with appropriate chemical or physical methods, and verifies elimination before we leave - not masked, removed.
UV Light Installation
UV light installation places germicidal ultraviolet lamps at the evaporator coil or in the return air stream to inhibit microbial growth on wet surfaces where mold and bacteria colonize continuously. This is particularly effective in Johns Creek’s climate, where cooling systems operate five to six months annually and coil temperatures create ideal conditions for biofilm development. We size and position UV-C lamps based on your system’s CFM rating and duct geometry, using equipment from manufacturers including Honeywell, and we document the installation location and lamp specifications in your written job record.
Air Purifier Install
Air purifier installation adds whole-house filtration or electronic air cleaning downstream of your central HVAC unit, treating every cubic foot of conditioned air rather than relying on portable units in individual rooms. For Johns Creek homes with open floor plans common in neighborhoods like St. Ives and The Falls of Autry Mill, this delivers consistent air quality throughout the living space without the noise and maintenance burden of multiple room units. We also offer Duluth Air Quality & Sanitizing for homes just west of the city. We specify and install media filters, electronic precipitators, or hybrid systems from Aprilaire and other trade-recognized manufacturers, with written performance specifications provided before installation begins.
Allergen Reduction
Allergen reduction combines physical removal, surface treatment, and filtration enhancement to lower concentrations of pollen, dust mite debris, pet dander, and other particulate triggers in your conditioned air. In Johns Creek, where oak and pine pollen seasons overlap from February through May, we see significant allergen loading in return ducts that pull air from exterior-facing rooms. Similar conditions affect homes to the north, where our Suwanee Air Quality & Sanitizing crews treat the same pollen and moisture patterns. Our process includes negative-pressure extraction of deposited material, sanitizing of reservoir surfaces, and recommendations for filtration upgrades - all documented in your photo record with particulate loading visible before and after treatment.

Brands We Service for Air Quality & Sanitizing
Our equipment roster includes professional-grade systems from Abatement Technologies, Guardsman, and Rotobrush - brands we select because their specifications are published, verifiable, and recognized in the HVAC trade. We’ve installed and serviced hundreds of Honeywell and Aprilaire whole-house air purifiers in Johns Creek and surrounding markets, and we stock replacement lamps, filters, and media for these units so follow-up maintenance doesn’t require a second scheduling window. When we specify a UV-C lamp output or a filter MERV rating, we do so with manufacturer documentation in hand, not marketing claims.
Whether your home currently has equipment from these manufacturers or any other make, we can evaluate its condition, document what we find, and recommend treatment or replacement based on what the inspection reveals. Our air quality and sanitizing service in Duluth follows identical standards, as does our work throughout the metro area. Every recommendation arrives in writing with a fixed price before you decide to proceed.
BeforeAfterSigns You Need Air Quality & Sanitizing Right Now
- Persistent musty or sour odors when the HVAC cycles on. This indicates microbial growth somewhere in the system, typically the evaporator coil or condensate pan, where standing water and organic debris create anaerobic conditions. The smell is not a cosmetic issue; it means the system is actively circulating metabolic byproducts from bacterial or fungal colonies into your living space.
- Visible mold or discoloration on vent registers or nearby ceiling surfaces. What you can see at the register often represents a fraction of what’s present upstream in the duct run or plenum. In Johns Creek’s humid climate, we regularly document mold extending several feet back from the register face, particularly in second-floor rooms where ductwork passes through unconditioned attic space.
- Allergy symptoms that worsen at home and improve when you leave. If antihistamines control your symptoms at the office but not in your bedroom, your HVAC system is likely the variable. We see this pattern frequently in newer Johns Creek homes with tight envelopes - excellent at keeping conditioned air in, equally excellent at concentrating whatever contaminants are already inside.
- Unexplained respiratory irritation in household members without outdoor allergy triggers. Bacterial endotoxins and fungal spores small enough to pass through standard filters can trigger inflammation in sensitive individuals. This is particularly relevant for young children and older adults whose respiratory defenses are less robust.
- Recent water intrusion, roof leak, or condensation event affecting ductwork. Even brief moisture exposure inside a duct run creates conditions for mold growth within 48 to 72 hours. If you’ve had a leak in a ceiling or wall where ductwork passes, the visible water damage is only part of what needs assessment.
Our Air Quality & Sanitizing Process - Step by Step
- 1
Systematic inspection with photo documentation. We begin by photographing the interior of every accessible duct run, the evaporator coil, the plenum, and the condensate drainage path. These images establish baseline conditions and identify which of our services - mold treatment, bacteria sanitizing, odor removal, UV installation, air purifier addition, or allergen reduction - are actually needed. You see these photos before we quote any work.
- 2
Written scope and fixed-price quote. Based on the inspection findings, we deliver a written proposal itemizing each recommended service, the equipment and materials to be used, and the total price. Haven Standard Clause 1 requires this price to be complete - no per-vent add-ons, no equipment surcharges, no post-arrival revisions. You approve or decline in writing before any treatment begins.
- 3
Contained treatment application. For mold and bacteria treatment, we seal registers and establish negative pressure to prevent chemical drift into living spaces. Application methods vary by contamination type and location - direct spray for accessible surfaces, fogging for extended duct runs, or foam application for dense coil fin matrices. Our crews use calibrated equipment from Nikro and Abatement Technologies with documented flow rates and dwell times.
- 4
Mechanical and filtration enhancement as specified. When UV lamps or air purifiers are part of the scope, we install according to manufacturer specifications with proper electrical connection, interlock safety switches where required, and airflow verification. We record lamp wattage, filter specifications, and installation location in your job file for future reference.
- 5
Post-treatment verification and photo record delivery. We re-photograph every treated surface and installed component, compile the before-and-after record, and deliver it with your invoice and warranty documentation. The 365-Day Done Right Promise applies from this moment - if any treated area shows recurrence or any installed equipment fails to perform as specified, we return to make it right at no additional cost.
How Much Does Air Quality & Sanitizing Cost in Johns Creek?
A typical mold treatment for a single-family home in Johns Creek runs $450-$850 depending on the extent of colonization, the number of affected duct runs, and whether the evaporator coil requires removal for access. For a broader look at what drives these figures, see our guide to Air Quality & Sanitizing pricing. Bacteria sanitizing for a complete system typically falls between $350 and $650. UV light installation ranges from $400-$750 per lamp assembly including hardware and electrical connection. Whole-house air purifier installation varies more widely - $600-$1,400 for most residential systems - based on the unit’s filtration technology, your ductwork configuration, and whether electrical circuit extension is needed.
Several factors move these ranges up or down. Homes with extensive flex duct in attic spaces take longer to access and seal for contained treatment. Older systems with degraded duct board may require repair before sanitizing can be effective. Multiple HVAC zones add complexity but also reduce per-zone cost when treated in a single visit. What we never do is quote a teaser rate over the phone and revise it upward once we’re on site - Haven Standard Clause 1 prohibits this practice, and our written price is the price you pay.
To avoid overpaying, request that any quote specify the exact services included, the equipment brands and model numbers to be installed, and whether the price covers the complete system or only selected duct runs. Ask for documentation of the technician’s findings before accepting any treatment recommendation. Our free estimates include all of this - inspection, photo record, written scope, and fixed price - with no obligation to schedule. Call (470) 326-1926 to arrange yours.

Frequently Asked Questions - Air Quality & Sanitizing in Johns Creek
Air quality and sanitizing targets living contaminants - mold, bacteria, viruses, and the odors they produce - while standard duct cleaning removes non-living debris like dust and construction residue. We recommend sanitizing when inspection reveals microbial growth, when occupants have unexplained respiratory symptoms, or when odors persist after mechanical cleaning. The two services complement each other; we often perform deep extraction cleaning before applying antimicrobial treatment so the sanitizer reaches the duct surface rather than sitting on top of loose debris.
Most residential treatments in Johns Creek require three to five hours from arrival to departure, including inspection, documentation, contained application, and post-treatment verification. UV light or air purifier installation adds one to two hours depending on electrical access and duct configuration. We schedule sufficient time so the crew never rushes the documentation or verification steps - these are what make the work accountable under the 365-Day Done Right Promise. Call (470) 326-1926 for an exact time estimate based on your system description - estimates are free.
Complete system bacteria sanitizing typically runs $350-$650, mold treatment $450-$850, and whole-house air purifier installation $600-$1,400 in the Johns Creek market. The final price depends on system size, contamination extent, and whether additional services like UV installation or advanced filtration are included. Every quote we provide is itemized, fixed, and delivered in writing before work begins - no per-vent pricing, no equipment surcharges, no post-arrival revisions. Call (470) 326-1926 for a written estimate specific to your home.
Yes - we install, maintain, and repair equipment from Honeywell, Aprilaire, and other manufacturers, and we stock replacement UV lamps, filters, and media for common residential models. Our crews carry manufacturer specifications for proper sizing and placement, and we document the installed equipment by model number in your written job record. If you have existing equipment from these or any other brand, we’ll inspect its condition and performance before recommending replacement or upgrade.
Air quality and sanitizing is a scheduled service, not an emergency dispatch. Active mold growth or persistent bacterial contamination warrants prompt attention - typically within one to two weeks - but does not require after-hours response. If you’re experiencing severe respiratory symptoms that you suspect are related to your HVAC system, we recommend consulting a medical professional while scheduling inspection as soon as practical. All calls are answered by a live person who can assess urgency and assign appropriate priority.
Every air quality and sanitizing job is backed by the 365-Day Done Right Promise - if the treatment does not perform as specified, if mold recurs in a treated area, or if installed equipment fails to deliver stated performance, we return to correct the issue at no additional cost. This is a written guarantee included with your job documentation, not a policy subject to manager discretion. Haven Standard Clause 4: Accountable Work requires this documentation on every job we complete.
Clear access to all registers and the indoor HVAC unit, secure pets in a separate area, and plan to be present for the initial inspection so we can review the photo findings with you before presenting the written quote. If anyone in the household has chemical sensitivities or respiratory conditions, inform us when scheduling so we can select appropriate treatment agents and ventilation protocols. We bring all necessary equipment, containment materials, and protective coverings - no preparation beyond basic access is required. Call (470) 326-1926 to schedule at your convenience.
