Key Topics
Each topic below links to a full research article. Start with what matters most to your situation.
Central Florida's subtropical climate creates HVAC contamination conditions unlike anything most of the country experiences. Year-round cooling, 74% average humidity, tight building envelopes, and a construction culture focused on energy efficiency combine to make biological contamination inside HVAC systems the norm rather than the exception.
Read the full article →Mold requires moisture, organic material, and the right temperature range. Your evaporator coil provides all three: it stays perpetually cold and wet, and the air stream continuously deposits organic particulates onto its surface. Once biofilm establishes on coil surfaces, it spreads through ductwork and amplifies with every degree of humidity.
Read the full article →Air quality testing measures airborne particle concentrations — PM2.5 (fine particles), PM10 (coarse particles), and specific contaminants like mold spore counts and VOCs. A laser particle counter gives immediate readings. Lab cassette samples capture mold spores and are sent to accredited labs for species identification and concentration counts.
Read the full article →Standard duct cleaning removes loose debris. Decontamination addresses biological contamination — mold, bacteria, biofilm — using EPA-registered antimicrobials applied under controlled conditions. These are fundamentally different services. One removes what fell in. The other eliminates what grew there.
Read the full article →Pet dander — microscopic skin flakes — accumulates in HVAC systems and becomes a reservoir of allergens that circulates throughout your home continuously. For allergy sufferers, it's not enough to manage pet exposure in one room if the air system is distributing dander to every room simultaneously.
Read the full article →Brand-new homes have a specific contamination profile: construction dust, drywall particulate, and adhesive off-gassing deposited in ductwork during the build process. These materials are hygroscopic — they absorb moisture — and create the substrate for biological growth within the first 1–2 years of Florida operation.
Read the full article →Children breathe at a higher rate per body weight than adults and spend more time at floor level where particle concentrations are highest. Their immune systems are still developing, making them more vulnerable to biological contaminants. Respiratory patterns established in childhood — including asthma — can persist for life.
Read the full article →An HVAC system doesn't just heat or cool air — it moves air throughout your entire home, touching every room multiple times per hour. Whatever is on the surfaces of that system — mold spores, bacteria, allergens, dust mite debris — is carried to every room simultaneously. Contamination at the source affects the entire home.
