Indoor Air Quality

620 CONSULTANTS LISTED

Indoor air quality consultants investigate the complaints that don't map to a single OSHA standard — odors, humidity, mold, ventilation adequacy, and building-related symptoms. Assessments typically measure carbon dioxide, carbon monoxide, temperature, relative humidity, and particulates against ASHRAE 62.1 ventilation benchmarks, with targeted sampling for mold or specific contaminants when screening justifies it. Moisture intrusion investigation is central: finding the water source matters more than counting spores. Many also review HVAC operation, outdoor air delivery, and filtration. Expect a structured investigation that starts with the building walk and occupant interviews, sampling only where it answers a real question, and a report that separates verified findings from hypotheses — without overpromising what IAQ data can prove.
