Suction line filter.............................(Starch)

I quoted a replacement condensing unit and A-Coil for a client, and they gave us the green light. The lineset is not completely accessible, as it runs through another (attached) condo unit before exiting the wall, so we are planning on reusing it.

Soooooooo, I'm at the supply house today to pick up the equipment, and I ask the guy for a suction line filter.

"Did you have a compressor burnout?" he asks me.

"No, this is just a replacement system - no burnout." says me, "the client is just concerned about the age of the unit, and wanted a new one."

"In that case, you want a liquid line filter, not a suction line."

Am I nuts? (Don't answer that) I was always told you should place the filter on the suction line. It seems to me I recall being told that in a burnout situation, a liquid line filter should also be used, but located at the evaporator.
