HVAC Mold Treatment
Kill mold where it hides.
Not just where you see it.
Traditional duct cleaning removes debris. Our EPA-registered HOCL treatment kills mold throughout your entire HVAC system—including places brushes can't reach.
Complete System Treatment
Every component. Every surface.
Mold doesn't stay in one place. Our treatment covers your entire HVAC system.
Air Handler Unit
The heart of your system where mold often starts. We treat blower motors, housing, and internal surfaces.
Evaporator Coils
Cold, damp coils are prime mold habitat. Our treatment penetrates deep into coil fins.
Supply & Return Ducts
Every inch of ductwork treated with HOCL fog that reaches corners brushes can't.
Registers & Vents
Where you see the evidence. We clean and treat all supply and return vents.
Drip Pans & Drain Lines
Standing water breeds mold. We clean and treat condensate systems to prevent regrowth.
Plenum & Transitions
Hard-to-reach junctions where ducts connect. HOCL fog reaches every surface.
The Hidden Danger
Your AC is a mold distribution system
When mold grows inside your HVAC, it doesn't stay put. Every time your system cycles, it pushes thousands of mold spores into every room with a vent. You're not just living with mold—you're breathing it continuously.
Health symptoms multiply
Respiratory issues, allergies, headaches, and fatigue that persist indoors
Whole-home contamination
One contaminated system affects every room in your house
System efficiency drops
Mold buildup restricts airflow, increasing energy costs up to 25%
HOCL Fogging Treatment
Hypochlorous acid fog penetrates every corner of your ductwork, killing mold where traditional cleaning can't reach.
- Kills mold, bacteria, and viruses on contact
- Reaches inside coils, plenum, and duct joints
- EPA-registered antimicrobial
- No toxic chemicals—safe for family and pets
- System usable in 1 hour

Common Questions
HVAC mold treatment FAQs
How do I know if my HVAC system has mold?
Common signs include musty odors when your system runs, visible mold or black residue around vents, increased allergy symptoms indoors, and unexplained respiratory issues. If you notice any of these, schedule a professional inspection.
What causes mold to grow in HVAC systems?
HVAC systems create ideal conditions for mold: darkness, moisture from condensation, and organic material (dust, debris) for food. Georgia's humidity makes this especially common. Clogged drain lines, oversized AC units, and poor maintenance increase risk.
Is HVAC mold dangerous?
Yes. Unlike localized mold, HVAC mold spreads spores throughout your entire home every time the system runs. This continuous exposure can cause respiratory issues, allergic reactions, headaches, and fatigue—especially in children, elderly, and immunocompromised individuals.
How is HOCL treatment different from duct cleaning?
Traditional duct cleaning uses brushes and vacuums to remove debris but doesn't kill mold. HOCL (hypochlorous acid) is an EPA-registered antimicrobial that kills mold, bacteria, and viruses on contact. It's fogged throughout your system, reaching areas brushes can't access, and leaves no toxic residue.
How long does treatment take?
Most residential HVAC systems can be fully treated in 3-4 hours. You can use your system again within 1 hour of treatment completion—no evacuation or extended downtime required.
Will the mold come back?
HOCL treatment kills existing mold and provides residual protection. To prevent regrowth, we recommend: changing filters regularly, ensuring proper drainage, controlling indoor humidity below 50%, and scheduling annual preventive treatments in Georgia's humid climate.
