Your air conditioning system runs almost continuously in South Florida. Every hour it runs, it is moving air through ducts, across coils and through vents into every room of your property. If mold has established anywhere in that system, every cycle distributes spores throughout the entire building. Not just the room where the mold is. Every room the system serves.
HVAC mold is the most commonly overlooked mold problem in South Florida residential and commercial properties because it is invisible from the living space. You cannot see inside your ductwork. You cannot see the evaporator coil behind the air handler cabinet. What you can detect is the musty smell that hits when the system first kicks on, the allergy symptoms that nobody in the household can explain, or the dark discoloration around supply vents that most people mistake for dust.
FixMold's HVAC mold remediation service identifies, eliminates and prevents mold throughout your entire air conditioning system using proprietary organic treatments developed specifically for this application, often as part of broader mold remediation services when contamination has spread beyond the HVAC system. State licensed, 35 years in this market, serving homes and commercial properties across all of South Florida.

What you see on the surface is rarely the whole story. Mold in South Florida almost always starts where you cannot see it, inside wall cavities, above ceiling tiles, behind bathroom fixtures, inside ductwork. By the time a dark spot appears or a smell becomes undeniable, the problem has usually been building for weeks.
Our certified inspectors use infrared thermal imaging cameras and calibrated particle counters to read your property the way no visual check ever could. Infrared detects temperature differentials that reveal trapped moisture behind surfaces. Particle counters measure what is actually in your air. Together they give us a precise picture of where mold is active, not just where it is showing.
Every sample we collect goes to an independent certified laboratory, not an in-house operation. Air samples, surface swabs and control readings are analyzed under microscopy and returned with full species identification and spore counts per cubic meter of air.
What sets our reports apart is what happens after the lab results come back. Your inspector sits with you and walks through every finding in plain language. You learn exactly what was found, what it means for your health and your home, and what the right next step looks like. No jargon. No pressure. Just a clear answer and a clear path forward.
FixMold focuses on eliminating mold from your environment.
But for some individuals, recovery doesn’t stop there.
Even after successful remediation, the body may continue responding to past exposure. In these cases, a structured, medically guided approach may be necessary to support full recovery.
Dust accumulation around supply vents is common and normal. The indicators that suggest mold rather than dust are a musty or sour smell that is strongest when the system first turns on and dissipates slightly as it runs, dark discoloration around vents that returns quickly after cleaning, and health symptoms in occupants that follow the pattern of being worse at home and better when away. A professional inspection with air sampling from multiple rooms compared to an outdoor baseline will confirm or rule out HVAC mold definitively.
Consumer duct cleaning approaches cannot reach the full interior surface of a duct system and cannot address mold that has penetrated into duct liner material. Disturbing mold in a duct system without proper containment and filtration can increase airborne spore concentrations throughout the property during the cleaning attempt. HVAC mold remediation requires professional equipment, organic antimicrobial treatment formulated for this application and post-treatment air quality verification. Attempting to address it without these elements risks making the air quality worse before it gets better.
Coverage depends on the cause and your specific policy. If HVAC mold resulted from a sudden covered event such as a drain line failure that caused water damage, many policies will cover remediation up to the mold limit. If it resulted from deferred maintenance or normal system operation over time, most policies will not cover it. We work with insurance claims regularly and can advise you on documentation during our assessment.
A residential single-system job typically runs three to five hours including inspection, coil cleaning, duct treatment, fogging and vent reinstallation. Larger homes with multiple systems or commercial properties with central air handling units and extensive ductwork take longer. Your inspector will give you a realistic time estimate based on your specific system after the initial assessment.
