I actually probably did too many rooms on one dust cloth. I swabbed bedroom, LR, Kitchen, master bath. I did not do second floor. Certain mold strains may point to possible HVAC mold. I can't remember which one....
Recently I did a petri dish by mold armor too. I taped it to hvac vent for 10 minutes. It grew 2 types of mold - but I think they are more allergen type molds. It was maybe $10 for the dish on amazon and $40 for the lab analysis. You can also set it out in the open air for an hour and see what it grows. Kinda cool.
