My window ac filter is clean but the fins behind it stink. I smoke and that in itself is bad but starting the ac stinks too much. It is a Kenmore 10000 about 10 years old. I have others to clean too but they are basically the same.
Is google my friend? Did not ask.

Why not. Search for an HVAC "comb" Clears the fins, straighten them
and get the cooties out.

There are foam sprays also. to clean the fins.
