I work for a company that needs to replace a scroll compressor for an old 5-ton 3 phase American Standard unit, model# ych060a3ela Part # com10259 Serial # 302100339l. I am not onsite and don't have access to the unit, but they have asked me to get info about replacing the scroll compressor. Does anyone know anything about this model? Any idea how much the scroll compressor is? I can't find anything on the web, I'm on a time deadline, any help would be appreciated.
