Trusted Mold and Air Quality Testing Helping Tampa Bay Homeowners Find the Source

IET Icon

You smell something musty, a family member keeps getting sick, water came in, or a lab report landed and you can't read it. Indoor Environmental Technologies answers those questions with data: whether mold or another contaminant is present, where the moisture feeding it started, and how far it has spread. Testing across Tampa Bay and the Gulf Coast since 1992.

Our Story

IET Icon

Founded in 1992, Indoor Environmental Technologies was born out of a clear need for comprehensive, science-driven solutions to indoor environmental challenges. Over the years, we have conducted more than 9,000 inspections across residential and commercial properties throughout Florida and the Southeast US. Our team recognized early on that many buildings suffered from hidden environmental hazards, and in St. Petersburg, FL, the climate creates favorable conditions for mold and mildew, along with chemical contaminants and moisture issues that can compromise occupant health and property value. We set out to fill this gap by combining advanced applied science with practical, actionable solutions tailored to each client’s unique environment.

Your Air Quality Equipment — Is It Actually Working?

IET Icon

Most Tampa Bay buildings already have filters, dehumidifiers, UV lamps, or ventilators installed. Whether any of it performs as sold is a separate question. We measure. We don't sell, install, or service HVAC equipment.

Filtration

High MERV ratings capture more airborne particulates, but a filter fighting static pressure or leaking around its frame performs like the cheap one it replaced. HEPA filters capture 99.97% of particles as small as 0.3 microns — pollen, pet dander, dust, mold spores. Activated carbon adsorbs odors, chemicals, and VOCs until it loads up, then stops working while looking identical. Before-and-after air sampling shows which is changing your actual counts.

Humidity

AC cools first and dries second, so a correctly sized unit in St. Petersburg, FL can still leave a home at 65% relative humidity. Whole-home dehumidifiers hold indoor humidity at 45–55%, where mold growth stalls. Smart thermostats are sold on maintaining consistent temperature and humidity. We log RH over time and across rooms to show whether either is holding.

Ventilation

Energy Recovery Ventilators bring fresh outdoor air in and push stale air out, transferring heat and moisture between streams. On the Gulf Coast, a misconfigured ERV adds humidity instead of removing it. Testing separates a ventilation problem from a source problem before you spend money on equipment.

UV Germicidal Systems

UV-C lamps in HVAC systems are designed to destroy the DNA of mold, bacteria, and viruses at the coil. Placement, intensity, and dwell time decide whether that happens. Surface and air sampling around the coil tells you if the coil is still a growth surface.

How We Find It

Hidden mold and VOCs require moisture meters, infrared cameras, and calibrated sampling sent to an accredited lab. Matthew Fitzgerald, MRSA5590, has run this work across Tampa Bay and the Gulf Coast since 1992.
