Mold in air conditioner?

A buildup of dust and grime can clog the drain line, causing moisture to drain slowly or not at all. This creates a damp environment and a home for mold growth, If it’s warm enough and damp enough, mold can start growing in your drain pan, in the condensate line, and even spread to other parts of your indoor unit, such as the blower fan. Ductwork mold can also take hold if you have leaky ducts. Leaks can allow mold spores inside, along with dust, heat, and moisture. That’s all mold needs to grow. If the air filter is clogged with dust and pet hair, it can start to retain moisture - which can allow mold to grow on the filter. That mold can then enter the HVAC system. Another potential cause of mold in your home, and by extension, your HVAC system is the AC unit itself. Improper AC sizing means that an overly-sized unit can cool your home quickly but fail to reduce the humidity properly. Talk with your HVAC professional about whether your AC unit is properly sized for your home.
