HELP! Is this mold or dust? It dissolved in bleach!

Hello! Found this in our wall AC and I think it’s why I’ve been chronically sick with a never ending stuffy nose, fatigue, headaches and killer sore throat!! Literally been sick all spring/summer! Since this appeared in our ac! My DH is ruthlessly lazy and refuses to help, he swears it’s nothing.. but that doesn’t look like nothing! And why am I still sick?!
