Microbial Treatment
Do You Know What’s Inside Your HVAC System?
Have you noticed musty odors, visible spots on your vents, or recently dealt with water damage in your home? These can be signs of microbial growth inside your HVAC system or ductwork.
At Air Quality Systems, we work closely with certified remediators throughout the Atlanta metro area to assess and address concerns related to microbial contamination in your air ducts and HVAC components.
Signs of Microbial Growth in HVAC Systems
Visible growth or discoloration on vents and registers
Persistent musty smells when the HVAC system runs
Past flooding or water intrusion near HVAC components
Increased allergy or respiratory symptoms indoors
Sometimes, growth is limited to vents and doesn’t pose a deeper threat. But in many cases, there are no visible signs—and the inside of the system may be heavily contaminated without you even knowing it.
Our HVAC Microbial Cleaning & Prevention Process
Air Quality Systems is equipped to clean most types of microbial-contaminated ductwork (depending on the material and accessibility). Our services help restore airflow, extend the life of your HVAC system, and reduce the likelihood of needing a full replacement.
Here’s what we do:

Full HVAC System Cleaning
We remove microbial growth from the air handler, blower fan, evaporator coil, and ductwork using specialized equipment and EPA-approved techniques.
Anti-Fungal Coating Application
After cleaning, we apply a specialized anti-fungal sealant inside insulated duct sections. This prevents spore spread, seals out air leaks, and helps stop future growth at the source.

Breathe Easier with Cleaner Air
If you suspect microbial growth in your HVAC system, don’t wait. Left untreated, it can affect your indoor air quality, system performance, and even your health.
Call Air Quality Systems today for an inspection and professional cleaning, or ask about our UV light and filtration options for long-term protection.
Helping Homeowners Recover After Fire or Water Damage
At Air Quality Systems, we’re proud to support homeowners during one of the most challenging times—recovering from fire or water damage. We understand that after the initial loss, the long road to rebuilding can feel overwhelming. You’re ready for life—and your home—to return to normal. We’re here to help make that happen.


The Final Step in the Restoration Process: Your HVAC System
In many cases, we’re the last stop in the restoration process. After the drywall is repaired, fixtures installed, and paint dries, what’s often overlooked is what’s hiding inside your air ducts.
Even when everything looks clean on the surface, your HVAC system may still contain:
- Smoke residue
- Moisture buildup from water damage
- Fine construction dust and debris
- Lingering odors from the disaster event
Left untreated, these contaminants can impact your indoor air quality, trigger respiratory issues, and continue to produce unpleasant smells long after the visible damage is repaired.
Specialized HVAC Cleaning & Smoke Odor Treatment
In addition to our standard air duct cleaning services, we offer a specialized anti-odor coating designed specifically for insulated HVAC components. This coating helps:
- Seal in and neutralize smoke odor trapped in duct insulation
- Prevent future microbial growth caused by residual moisture
- Restore clean, fresh airflow throughout the home
