I posted a similar question about a month ago and many of the posters said
is was basically a waste of money.

You asked if cleaning the ducts would improve the air flow, and you
were told not to expect that. As for a the cleaning itself, it is
absurd to suggest that it would be a waste of money. If the ducts have
an inch of dirt in them, is it a waste? Do you vacuum your house?

I posted about my experience, and I didn't think it was a waste of
time at all. If you did it once every year, it would be a waste.

As far as the question of disinfecting from the OP, they shouldn't
expect miracles, but the disinfectant will disinfect what it reaches.
If the cause of mold or whatever remains, then the disinfectant will
have a temporary effect.
