Indoor Air Quality Testing

IAQ Assessment That Follows Published Science

Indoor air quality problems are frequently invisible. Elevated CO₂, volatile organic compounds, biological contaminants, and airborne particulates affect occupant health long before symptoms become obvious or a source is identified.

Every IAQ assessment at Coastal Air Assessments follows protocols from the American Industrial Hygiene Association (AIHA) and the American Conference of Governmental Industrial Hygienists (ACGIH) — the organizations that define scientific best practice for indoor environmental investigation. Not proprietary methods. Not franchise checklists. Published, peer-reviewed science.

IAQ assessment services include:

• CO₂ monitoring — ASHRAE 62.1 and AIHA guidelines evaluate ventilation adequacy. Elevated CO₂ above 1,000 ppm in occupied spaces indicates insufficient fresh air and is a leading cause of occupant performance complaints and health symptoms in offices, schools, and multi-family buildings
• VOC testing — Chemical off-gassing from building materials, furnishings, finishes, and renovation products evaluated against ACGIH and EPA reference values
• Particulate analysis — PM2.5 and PM10 airborne particle counts evaluated against established health-based guidelines
• Biological sampling — Mold spore counts and allergen sampling following AIHA field guide protocols
• HVAC evaluation — Systematic assessment of blower components, coils, and ductwork as biological and particulate sources
• Moisture and humidity assessment — Quantified readings that define the conditions driving biological growth
• Thermal imaging — Building envelope deficiencies that create localized moisture and biological growth conditions

IAQ in South Florida’s climate

South Florida’s subtropical environment creates IAQ challenges that require regional building science expertise. High exterior humidity drives moisture inward through building assemblies. Continuous air conditioning operation accumulates biological contamination on coil surfaces and in duct systems. Well-sealed, energy-efficient buildings concentrate pollutants and deplete CO₂ dilution. Recognizing these climate-specific patterns is what separates a building science assessment from a generic checklist.
