Window air conditioner question

[Guest guest]

My friend with the duct issues that were so kindly addressed here, had them

cleaned anyway because the landlord paid for it. Like everyone said, it did not

work, being the flex duct. As a matter of fact, it seems to have made matters

worse. Now he wants to try window air conditioners, instead of moving. Does

anyone know of any type of window AC that would be better than any others? and

is there any special way to keep them from not molding? Also I have heard that

electrostatic air filters actually irritate the mold spores and make matters

worse. True anyone?
