I am often called to test or evaluate a customer’s “air quality.” An air quality inspection is a very broad request considering the vast number of potential contaminants and pollutants. The vast number of potential culprits, paired with the limitation that there is no “magic” test that can identify every single contaminant in the air, leads to a very broad scope of work. Without going into the endless list of pollutants, contaminants, and the test necessary for each: I will just ask you a simple question. Look at the picture of this air conditioner duct. What you see is a build-up of pet hair, dander, skin cells, dust, dust mites, gypsum dust, spider webs and a few unknowns.
Did this customer really need an air quality inspection?
