    One of my 4 units is spewing black particles. I have had it cleaned by technician​. He says it is best he can do but suggests buying an additional filter which I can clean as needed. The system is some years old but working well. I have not found a filter that fits this unit on line. Can you help.

    Where can an individual buy parts for a ASU9RMLQ? I purchased my unit in 2007 and so far have not had to purchase anything for my units. Lately I am noticing a binding sound when the fan is running. Since the warranty is expired on the units I am ready and willing to try to fix the problem. But I am reluctant to dismantle the unit if I can not purchase the parts that may need to be replaced.
    Thank you for your input.
