Our first coach was owned by heavy smokers, so there was tar everywhere, including the vents. I used a coat hanger wrapped around a sponge soaked in cleaner (I would use a bleach solution in your case) and pulled the sponge between vents. You can get most of it that way, but the duct to the A/C isn't accessible without removing the A/C, I would think. Make sure the wire attachment is secure or you'll lose the sponge in an awkward place. Don't ask me how I know!

An ozone generator supposedly will help, too.

Are you sure it is in the ducts? Could it be water standing in the A/C evaporator coil catch pan not draining.

I don't know if you want to do it yourself, or have someone do it for you. If you want them cleaned thoroughly try using one of those services that clean home duct work. I'm sure they can do it right for you. They will also know the best way to mediate mold if that is your problem.

An electric leaf blower and towels to block other ducts can be used to blow a string through the system then use that string to get fishing line or better weed trimmer cord as it is slippery and fat enough to maybe not get caught in corners.

Make a loop tying ends together so you will not loose the end.

Not sure about rag or cleaner.

Duct cleaning folks may be your best bet if you drive to them.
