HVAC Sanitization
Breathe cleaner air.
Starting with your ducts.
Mold hiding in your HVAC system spreads spores throughout your home every time the air runs. Our EPA-registered treatment eliminates mold at the source—safely, with no toxic chemicals or evacuation required.
Self-Assessment
Is there mold in your HVAC system?
Check for these warning signs. If two or more apply, your air ducts may need professional treatment.

Allergy symptoms indoors
Sneezing, congestion, or itchy eyes that improve when you leave
Black dust around registers
Dark residue collecting on or near your air vents
Inconsistent airflow
Some rooms getting less air, indicating possible duct blockage

Why It Matters
Your HVAC spreads more than air
When mold grows inside your air handler, coils, or ductwork, every cycle of your HVAC system pushes spores throughout your entire home. That musty smell? It's millions of mold spores circulating through the air you breathe.
Health risks multiply
Respiratory issues, allergies, headaches, and fatigue—especially in children, elderly, and those with compromised immune systems.
Whole-home contamination
Unlike localized mold, HVAC mold spreads spores to every room with a vent. One contaminated system affects your entire living space.
HVAC efficiency drops
Mold and debris buildup restricts airflow, forcing your system to work harder and increasing energy costs by up to 25%.

Common Questions
HVAC mold FAQs
Frequently Asked Questions
How do I know if there's mold in my HVAC system?
The most common signs are a musty odor when your system runs, visible mold around vents, unexplained allergy symptoms that improve when you leave home, and black dust accumulating near registers. If you notice any of these, schedule a professional inspection.
Can mold in air ducts make you sick?
Yes. When mold grows in your HVAC system, spores circulate throughout your home every time the system runs. This can cause respiratory issues, allergic reactions, headaches, and fatigue. People with asthma, allergies, or compromised immune systems are especially vulnerable.
Why use HOCL instead of traditional duct cleaning?
Traditional duct cleaning removes debris but doesn't kill mold at its source. HOCL (hypochlorous acid) is an EPA-registered antimicrobial that penetrates deep into porous materials, kills mold spores on contact, and leaves no toxic residue. It's the same compound your immune system produces naturally.
How long does HVAC sanitization take?
Most residential systems can be fully treated in 2-4 hours. The HOCL treatment dries quickly, and you can use your HVAC system within 1 hour of treatment completion. No evacuation required.
How often should I have my HVAC system treated?
In Georgia's humid climate, we recommend annual treatment for prevention. Homes with history of moisture issues, visible mold, or occupants with respiratory sensitivities may benefit from bi-annual treatment.
