Mold on A/C vents

We just had a new heat pump and central A/C installed. The install included all inside and outside components plus new duct from return air and new ducts into our den area. I just noticed that there appears to be a little mold on the den vents and vents in the kitchen (ducts not replaced there). The installers did not say anything about the ducts having mold.

I am a little uncomfortable with the mold i can see on the den and kitchen vents. What would you recommend I do? My first thought was to attempt to kill the mold but my research found conflicting opinions on how to do this. Do you think I would be better off just replacing the vents in question? There are only 4 of these vents. One of the vents in the kitchen has a small amount of, what looks like mold, on the ceiling around the edge of the vents. What would you suggest I use to kill this mold.

Thanks in advance for your advice.

Can you remove the vents and soak in bleach and water?

Are you in an extremely high humidity area ?

Sometimes dirt and condensate water mix and look like mold.
Take the vents off and look into the ductwork. See if there is mold in the ducts.

Cleaning with warm soapy water and bleach is all that is needed.

Just clean them with any household cleaner that you have. Should come right off the metal register.

Yes, I can do that. What ratio bleach/water would you recommend?

Thanks for the reply.

Use a cup of bleach in a bucket of water. Add a squirt of dish washing soap
The exact proportion isn't critical.
