Testing Measures
Air quality testing uses instruments to measure specific pollutant concentrations: PM2.5, VOCs, CO2, radon, mold spore counts. The output is a number. Testing tells you what is in the air at the time of measurement. It does not tell you where it came from, why it is there, or what to do about it.
Assessment Investigates
An air quality assessment evaluates the home's systems, materials, conditions, and patterns to identify sources and recommend changes. It covers HVAC, ventilation, allergens, chemicals, and moisture. The output is a diagnosis with prioritized recommendations. An assessment tells you what is causing the air quality problem and what to change.
Which Do You Need?
If you need a number for documentation (medical, legal, insurance), you need testing. If you need to understand what is going on and what to do about it, you need an assessment. Often the most efficient approach is assessment first, testing second if the assessment identifies a concern that warrants quantitative confirmation.
