There are 3 different testing methods: 1) indoor air quality to test for mold spores, 2) the AC/heating mold sampling tests the air from a forced air heating and air conditioning unit, and 3) surface mold sampling which test mold that is already growing on a surface. If you suspect you are being affected by mold in the Doylestown, PA area, you can have a mold inspection to confirm whether you are or are not. Sooner is better.
