How much does duct mold removal cost in Miami?
+
The cost of duct mold removal in Miami depends on the size of your duct system, the severity of the mold, and the services required. We offer a FREE verbal estimate (on-site inspection, no cost, no obligation) and an $89 written estimate with a detailed breakdown of the work needed. Every home is different, which is why we inspect first and give you an honest recommendation before any work begins.
How do I know if I have mold in my air ducts?
+
Common signs of mold in your air ducts include: musty or earthy smell when the AC turns on, visible mold on vent covers or inside ducts, unexplained allergy symptoms or respiratory issues that worsen indoors, black or green spots around vents, and increased humidity in your home. In Miami’s climate, mold in ducts is extremely common due to year-round humidity above 80%. If you notice any of these signs, schedule a free mold inspection.
Can mold in AC ducts make you sick?
+
Yes — mold in your AC ducts can absolutely make you sick. When your AC runs, it blows air through mold-contaminated ducts, sending mold spores throughout your entire home. This can cause respiratory infections, allergic reactions, asthma attacks, headaches, fatigue, and sinus problems. Black mold (Stachybotrys) can produce mycotoxins that are particularly dangerous. Children, elderly, and people with compromised immune systems are most at risk. The EPA ranks indoor air pollution as a top 5 environmental health risk.
How long does mold remediation take?
+
A standard duct mold remediation takes 4-8 hours depending on the size of your duct system and the severity of the mold. This includes inspection, surface cleaning, deep sanitizing, BioFresh fungal treatment, and duct sealing. If additional services like air purification installation or duct replacement are needed, the job may take a full day. We complete most residential jobs in a single visit.
What is BioFresh fungal treatment?
+
BioFresh is a professional-grade fungal treatment we apply inside your ductwork after cleaning. Unlike regular cleaners that only remove surface mold, BioFresh penetrates into the duct material to kill mold at the root level and leaves a protective barrier that prevents regrowth. It’s safe for your family and pets once dry, and it’s specifically formulated for HVAC systems. BioFresh is one of the key differences between mold cleaning and true mold remediation.
Do you offer UV lights to prevent mold?
+
Yes — we recommend UV germicidal lights as the long-term solution for mold prevention in your duct system. UV lights are installed inside your air handler and work 24/7 to kill mold spores, bacteria, and viruses as air passes through. Combined with our mold remediation service, UV lights dramatically reduce the chance of mold returning. We offer UV light installation as part of our remediation process or as a standalone service.
How often should ducts be sanitized in Florida?
+
In Florida, we recommend duct sanitization every 6 months due to our extreme humidity and year-round AC usage. Miami’s climate creates the perfect conditions for mold growth — warm temperatures, high moisture, and dark duct interiors. Homes near the coast, homes with pets, or homes with residents who have allergies or asthma may benefit from more frequent sanitization. After a full mold remediation, regular sanitization prevents mold from returning.
What’s the difference between mold cleaning and mold remediation?
+
Mold cleaning only removes visible mold from surfaces — it does NOT kill the mold at the root or prevent regrowth. Mold remediation is a complete process: we assess the mold type and severity, clean the surface mold, deep sanitize for embedded mold, apply BioFresh fungal treatment to kill mold at the root, seal ducts with mold-resistant sealant, and can install hospital-grade air purification technology that continuously kills mold 24/7. Cleaning is a temporary fix. Remediation is the permanent solution.
I have black spots on my AC vents — is that mold?
+
Yes — black or dark green spots on your AC vents are almost always mold. In Miami’s humid climate, condensation forms on vent surfaces and creates the perfect environment for mold growth. If you see black spots, discoloration, or fuzzy growth on or around your AC vents, do not try to clean it yourself — disturbing mold can release spores into the air. Call a licensed HVAC contractor for a free mold inspection. We assess the problem and recommend the right treatment.
Why does my AC have mold?
+
Your AC system creates the perfect conditions for mold: dark enclosed spaces, constant moisture from condensation, and organic material (dust, skin cells) for mold to feed on. In Miami, your AC runs 10-12 months per year with 80%+ humidity — that’s more mold-producing conditions than anywhere else in the country. The evaporator coil, drain pan, and ductwork are the most common locations for mold growth. Without regular sanitization, mold is virtually guaranteed in South Florida AC systems.
If I have mold in my AC, what should I do?
+
First, do not turn off your AC — this can cause humidity to spike and mold to grow faster. Do not attempt DIY mold removal — you can spread spores and make it worse. Call a licensed HVAC contractor (not a handyman or carpet cleaner) for a professional mold inspection. We provide free inspections — we’ll assess the mold, tell you exactly what’s needed, and give you an honest estimate on the spot. The sooner you act, the less expensive the remediation.
