Indoor Air Quality Inspection

A professional indoor air quality inspection provides a comprehensive picture of the pollutants, allergens, and conditions inside your home. Our certified inspectors use laboratory-grade equipment to deliver accurate, actionable results.

What a Professional IAQ Inspection Covers

A comprehensive IAQ inspection by a qualified professional typically includes a visual inspection of the entire building envelope — looking for moisture staining, visible mold, deteriorated insulation, and signs of pest activity. It includes inspection of the HVAC system: air handler condition, filter status, coil and drain pan, ductwork accessibility.

Depending on the scope, it may include air sampling (for mold spores, particulates, or specific chemicals), surface sampling (tape lifts or bulk samples for mold identification), CO2 measurement as a proxy for ventilation adequacy, and use of a moisture meter to identify hidden damp areas in walls and floors.

ASHRAE’s Indoor Air Quality Guide recommends that baseline CO2 levels below 1,000 ppm indicate adequate ventilation in occupied spaces. Levels above 1,100–1,200 ppm consistently suggest inadequate outdoor air supply and require investigation of the ventilation system. A calibrated CO2 meter is a standard tool in any professional IAQ assessment.

What Qualifies as a "Qualified" Inspector in Florida

In Florida, the mold-specific portion of an IAQ inspection — mold assessment — requires a Florida-licensed Mold Assessor license, issued by the Department of Business and Professional Regulation (DBPR). This is separate from the Mold Remediator license. An assessor evaluates the mold problem; a remediator performs the cleanup. The same company cannot hold both licenses for the same project, which is a Florida consumer protection requirement.

For broader IAQ work beyond mold (VOC testing, ventilation assessment, particulate measurement), credentials to look for include: Certified Industrial Hygienist (CIH) from the American Board of Industrial Hygiene (ABIH); Indoor Air Quality Association (IAQA) professional designations; and ASHRAE membership with IAQ-related credentials.

The AIHA (American Industrial Hygiene Association) publishes guidance on IAQ investigator qualifications. Be skeptical of inspectors who recommend remediation before completing an unbiased assessment, or who quote remediation services during the inspection — Florida law prohibits mold assessors from also performing remediation on the same job.

After the Inspection: Interpreting Your Report

A quality IAQ inspection report should clearly distinguish between findings (what was observed), measurements (air sample results, moisture readings, CO2 levels), interpretation (what the data means relative to established guidelines), and recommendations (prioritized action items).

When mold air samples are included, the report should compare indoor spore levels and species composition to outdoor baseline samples — elevated indoor counts or a species profile that differs significantly from outdoor air are the key indicators of an indoor mold source. The AIHA’s guidelines for mold investigations provide the framework most qualified assessors use.

Be prepared to act on recommendations promptly. In South Florida’s climate, moisture problems escalate quickly — a slow roof leak or compromised window seal can progress from a damp wall to active mold growth in under a week during summer. Prioritize structural moisture issues, then HVAC deficiencies, then source removal.
