AfterHow Much Does Air Quality & Sanitizing Cost in Alpharetta?
Air quality and sanitizing services in Alpharetta, GA typically cost between $250 and $650 for a standard whole-home treatment in 2026. Smaller jobs, like sanitizing a single HVAC air handler or treating a specific room after mold remediation, usually fall in the $150 to $300 range. Most Alpharetta homeowners we work with plan for $350 to $500 when they want ducts cleaned and sanitized together, which is the combination we recommend for families dealing with allergy symptoms or that musty smell that lingers after rain.
Below you’ll find the exact line-item costs, what makes a job shift toward the higher or lower end, and how to avoid paying for services you don’t need. If you’re in Alpharetta, Milton, Roswell, or Johns Creek, call us at (762) 263-0408 and we’ll give you a written price before anything starts.
Air Quality & Sanitizing Cost Breakdown (2026)
Here’s what we’re actually seeing across Alpharetta this year, from Windward to Crabapple and over toward downtown Alpharetta. These numbers reflect jobs completed by Morton’s Air Duct Cleaning and conversations with suppliers and fellow Cedarwell network members in North Fulton.
| Service | Typical Range | What’s Included |
|---|---|---|
| Whole-home air duct sanitizing | $300 – $550 | Full supply and return duct treatment, fogging or spray application, no furniture moved |
| Air duct cleaning + sanitizing (combined) | $450 – $750 | Rotobrush or Nikro cleaning of all accessible ducts, then sanitizer application. Most popular in Alpharetta |
| HVAC coil and air handler sanitizing | $150 – $300 | Evaporator coil cleaning and antimicrobial treatment, blower housing wiped down |
| Dryer vent cleaning + sanitizing | $130 – $220 | Vent line brushed from both ends, lint removed, antimicrobial fog where accessible |
| Odor treatment (single room) | $180 – $350 | Localized treatment for pet odors, smoke, or post-water-damage smell |
| Whole-home UV light or air purifier add-on | $450 – $900 | Honeywell or Aprilaire unit installed at the air handler, includes sanitizing of the immediate area |
Key takeaway: If your house in Alpharetta is 2,500 square feet or under, two stories, one air handler, you’re almost always in the $450 to $600 range for a full duct cleaning plus sanitizing. Add a second air handler (common in newer builds along Rucker Road and Webb Bridge Road) and you’re looking at $600 to $750.
Why the range?
The spread exists because no two Alpharetta homes are identical. A 1990s ranch in Nesbit Ferry Crossing with flexible duct runs and two returns costs less to treat than a 2020 three-story craftsman off Old Milton Parkway with rigid ductwork, a zoned system, and a media cabinet full of Aprilaire filters. We quote by the actual linear footage of ductwork and the number of supply registers, not by square footage of the home.
What Affects Air Quality & Sanitizing Pricing in Alpharetta
Here’s what actually moves the number on your written estimate:
- Number of air handlers and zones. Newer Alpharetta homes, particularly in neighborhoods like Halcyon and The Manor, often run two or three systems. Each air handler needs its own sanitizing pass, which adds $150 to $250 per unit.
- Ductwork accessibility. Some crawlspaces in older Alpharetta homes off Mid-Broadwell Road are tight and muddy after spring rains. If our techs need extra time to reach returns in a low crawl, that time is reflected in the price. We’ll tell you before we start.
- Pet load and odor severity. A house with two golden retrievers and a cat living in Windward will need a longer dwell time for odor-neutralizing treatment than a pet-free townhome. Pet-safe product choices are available, and we’ll walk you through which sanitizer we plan to use before the job begins.
- Prior mold or water damage. If you’ve had a leak in a bathroom or laundry room in Alpharetta and are treating for mildew, we may recommend treating the affected branch line separately. That’s a targeted service at $180 to $300 rather than a full-home pass.
- Filter and media condition. If your Aprilaire media cabinet or Honeywell filter slot is holding a filter that hasn’t been changed in two years, we’ll note it. Replacing a media filter during service adds $40 to $90, and it genuinely changes indoor air quality within days.
- Season. Alpharetta’s pollen season from mid-March through late April drives a lot of homeowners to book sanitizing services. Prices at Morton’s stay the same year-round, but availability tightens. If you’re planning ahead for spring, calling in February gets you the widest scheduling window.
Is Air Quality & Sanitizing Worth the Cost in Alpharetta?
For most families, the answer comes down to what’s in the air. Alpharetta sits in a bowl of Georgia pines, oaks, and construction dust. Spring pollen settles in ductwork and recirculates every time the AC kicks on. Combine that with the humidity of a North Georgia summer, and you get the stuff that makes kids sniffle and parents wonder why the house smells a little off.
Sanitizing the duct system after a cleaning adds measurable value. The cleaning removes the physical debris. The sanitizing step then treats the surfaces where bacteria and mold spores liked to sit. Families with infants, asthmatic kids, or elderly parents report the biggest difference, and we notice it on every appointment in Alpharetta.
Realistically, if your home hasn’t had its ducts cleaned or sanitized in the past five years, and you’ve got two or more pets, the $450 to $600 combined service will likely pay for itself in reduced allergy medication, fewer HVAC service calls, and a house that doesn’t carry that faint kennel smell into the summer.
How to Save on Air Quality & Sanitizing
- Time it with duct cleaning. Sanitizing is more affordable when it’s bundled with a full duct cleaning, since we’re already set up with equipment in every room. Doing them separately costs more in labor and setup for both visits. Bundle them and schedule once.
- Change HVAC filters before you call. If your filter is doing its job, the sanitizer we apply works better and lasts longer. It also means we don’t need to spend service time swapping out a heavily loaded filter at a higher materials cost. A fresh filter also makes the post-service air smell cleaner, faster.
- Ask about annual maintenance plans. Many homeowners in Alpharetta don’t realize that maintenance plans often include discounted sanitizing and priority scheduling during spring pollen spikes. If you’re already having annual HVAC tune-ups, ask your provider if they offer a plan discount on indoor air quality services.
- Address small leaks early. A tiny bathroom leak in a home near Wills Park can lead to musty return air that requires a full sanitizing treatment. Fixing the leak early keeps you at the $150-$250 targeted-treatment range instead of the $500+ whole-home job.
- Bundle dryer vent service the same day. If we’re already at your Alpharetta home with the Rotobrush equipment, adding a dryer vent cleaning and sanitizing is quick work. The line-item is less than scheduling it as a standalone call. Plus, it means one morning of service instead of two.
The biggest savings rule: get a written price before anyone starts. At Morton’s Air Quality & Sanitizing in Alpharetta, that’s how every visit works. You’ll see the number, understand the plan, and approve it before our techs bring equipment inside. If another company won’t put the price in writing, that’s a reason to pause. Estimates are free if you call (762) 263-0408.
Can You Sanitize the Air Without Chemicals?
In short: yes, within limits, and it starts with dry cleaning and UV light rather than fogging. Some Alpharetta homeowners on well water or with immune-compromised family members prefer to avoid chemical sanitizers. Here are the options we walk through with those families:
- High-efficiency particulate air (HEPA) vacuuming: We run HEPA-filtered collection on the Rotobrush or Nikro equipment, which physically removes dust, pollen, and dander rather than treating surfaces. This is the baseline for anyone who wants a clean duct system without any chemical product.
- UV-C light treatment at the air handler: Short-wave ultraviolet light neutralizes a high percentage of bacteria and mold spores passing the coil. Units from Honeywell and Aprilaire are effective when properly sized. For best results in an Alpharetta home, the UV light should be combined with a clean coil and filter, since UV cannot penetrate a blanket of pollen or dust.
- High-heat or steam sanitizing: Some homeowners choose a hot water extraction or dry steam pass through accessible duct sections. It’s slower and costs more, but it’s the best option when you want no chemical residue. If you’re looking at steam sanitizing, expect pricing of $600 to $900 for a full home, because of the time and equipment involved.
Ask your technician which option fits your family. We’ll tell you what we’d use if it were our own home, and that’s usually a combination: HEPA cleaning first, then a light, EPA-registered antimicrobial fog where needed. Every product we use in a home with kids and pets is reviewed for safety before it leaves the truck.
Air Quality Tests and Inspections in Alpharetta
Before you agree to any sanitizing work, it’s worth knowing whether you’re treating a real problem or just doing preventive maintenance. Most air duct and sanitizing companies in the Alpharetta area will charge between $75 and $150 for an air quality test (checking for mold spores, pollen load, and sometimes volatile organic compounds) or will roll the cost into the service if you hire them for the cleaning itself. Morton’s doesn’t run a separate testing lab, but our technicians will do a visual inspection of the supply and return plenums, the coil, and the duct boots before they ever write an estimate.
If your inspector finds visible mold growth on the duct lining, the job becomes more involved. Remediation-level treatment is a different service from sanitizing, and it’s not something we can responsibly gloss over. In Alpharetta, if we find active mold inside ductwork, we’ll tell you straight up and refer you to a remediation specialist. We’ll also tell you that we’re happy to come back after remediation to clean and sanitize the newly treated system, and that service falls in the standard $450 to $750 range.
FAQs – Air Quality & Sanitizing Cost
How much does air quality and sanitizing cost in Alpharetta?
Most Alpharetta homeowners pay $250 to $650 for air quality and sanitizing in 2026. A full duct cleaning plus sanitizing bundle for a typical 3-bedroom home runs $450 to $600. Add a second air handler or a UV light and you’ll move toward the top of that range. Call (762) 263-0408 for a written quote, and we’ll give you the exact number before any work starts.
Is it cheaper to sanitize or replace ductwork?
Sanitizing almost always wins on cost. Full duct replacement in Alpharetta runs $3,000 to $8,000 depending on home size and duct location, while sanitizing runs $250 to $650. Replacement only makes sense when ducts are physically damaged, collapsed, or contaminated beyond what cleaning and sanitizing can address. If you’re unsure, we’ll tell you straight during the inspection rather than pushing a service you don’t need.
Can I sanitize my own air ducts in Alpharetta?
You can, but the results are limited. The sanitizer products sold at Alpharetta hardware stores are typically too weak to treat the full internal surface area of your ducts. A professional service uses $3,000 to $10,000 fogging equipment and specialty brushes that reach every bend. More importantly, if you spray a chemical into your ducts without first removing the dust and debris, you’re just adding moisture to the buildup. We’ve seen it lead to worse smells later. For a truly clean result, the cleaning and the sanitizing need to go together.
How long does air quality and sanitizing take?
A standard Alpharetta home takes 2 to 5 hours for combined duct cleaning and sanitizing. The sanitizing itself is the quick part, usually 30 to 60 minutes of fogging and dwell time. The real time goes into the cleaning: every register, every return, and the air handler. We’ll tell you the schedule in advance, and our techs are fine working around nap times.
Do I need to do anything before the crew arrives?
Not much. Move any small items off the floor near your main return, and decide if you want us to focus on any specific room (like a nursery or a home office where someone with allergies sleeps). We bring shoe covers and drop cloths for every visit, so your floors are protected from the moment we walk in. Before we leave, we take a photo of the clean-up and you’ll get it with your invoice.
Why do some companies charge so much less?
If you’re getting an Alpharetta quote for $99 whole-home sanitizing, that’s a red flag. You’re likely looking at a bait-and-switch where a salesperson gets in the door and then finds “mold” that needs a $2,000 treatment. Real sanitizing involves HEPA collection, professional rotating brushes, and EPA-registered products applied with fogging equipment. Those costs aren’t avoidable. We don’t run teaser prices, because we give you the written price before anything starts and we honor it.
How We Work at Morton’s Air Duct Cleaning
Morton’s Air Duct Cleaning has been part of the Cedarwell family since 2005.

Every Morton’s technician is background-checked, uniformed, and trained on equipment from Rotobrush, Nikro, Honeywell, Aprilaire, Abatement Technologies, and Guardsman.
We’re not a chain. We’re an independent Cedarwell company owned and operated locally, led by Paul Adeyemi. Paul set the standard in 2005 and hasn’t relaxed it. If the job isn’t done right, the 365-Day Done Right Promise means we make it right. Full stop. No fine print, no arguing, no “well, if you’d purchased the premium package.”
We know what an Alpharetta home deals with, because we’ve worked in them since 2005. We know the pollen load in Windward in April. We know the cookie-cutter HVAC closets in Halcyon townhomes. And we know the difference between a house that just needs a cleaning and one that needs a more careful sanitizing plan. When you call, a real person picks up, day or night. You’ll get an appointment window that works around your week, a written price before we start, and a before-and-after difference you can smell and see.
