There are ways to flush the AC for real, but most people never need
to use them. And unless you have the symptoms that need fixing,
they're simply a waste of money and time.
If you get a stinky air conditioner because of buildup of mold or
bacteria in the heater box from the wet conditions on the evaporator
coil, or the drain line keeps getting clogged by slime molds, they
have a chemical cleaner that they spray into the heater box. That
foaming alkali cleaner dissolves the gunk so it flushes out through
the condensate drain, and changes the PH so it won't come back for a
while.
They also have "Pan Tabs" (meant for home systems) that time release
the drain-cleaning part of the chemistry, to keep the mold away for
several months. (Like a little urinal cake, they dissolve over time.)
You need a bigger access hole to get them inside.
There is also an internal flush for the refrigeration sealed system,
but that's usually only needed for home AC systems - on a car the
compressor drive is external, there is no electric motor to burn up.
And chemical conditions that cause problems inside are rare.
On home/commercial AC systems, if the hermetic compressor motor
burns up it is sealed inside the refrigeration system and spreads a
lot of acids and debris through the system. The debris and acidity
will hurt the new compressor if left inside.
