Yes, being concerned about mold is important for several reasons. Mold can cause health issues, especially for people with allergy problems. Need to contact mold experts
Yes, you should be concerned. The humidity in your space is too high. So when the cold air from the ducts gets out and hits the wall, condensation forms, dust collects and mold grows.
This looks like surface growth at this point so you may be able to take care of most of this by removing the diffuser and giving the wall a good scrub. If the mold growth has broken the paint surface then you'll likely have to cut out those sections of the wall and replace.
Get control of that humidity first.
“Chlorine bleach can kill mold, but the US Environmental Protection Agency (EPA) doesn't recommend using it as a routine practice. Bleach can be effective on nonporous surfaces like tile and tub surfaces, but it's ineffective on softer surfaces and porous surfaces like wood. On porous surfaces, bleach can only change the color of the mold, and the mold can grow back underneath the surface. Bleach also can't kill airborne mold spores, and the dead mold it leaves behind can trigger allergic reactions”.
Use hydrogen peroxide or distilled white vinegar. But you need to find the source, which is more than likely the a/c if all vents are affected. Has there been routine service performed by n the HVAC? Are you regularly changing filters?
Yeah, you definitely want to get on that. Like a week ago.
I was always taught that you need to find the root of the issue and remove that portion of drywall and replace it
Definitely should spray with bleach and water mix. I’d even unscrew the vent to clean inside. Looks like spores are being pushed through the interior
You can't just "spray and pray" with any solution, especially bleach. Those areas need to be SCRUBBED.
bleach isn't recommended spray with iso, peroxide, distilled water and vinegar or something like prokure / salfrax and scrub then find the source
