I live in a home built after 2000 that had aluminum wires run to its heat pump. A few years back coolant leak from the heat pump lead to huge electric usage before the aluminum wiring lit on fire and shorted itself out. Since repaired, but was told at the time original installer didn't correctly do the aluminum grease on the exposed wire parts.
That said I think the wiring there is still thick aluminum.
Not sure I really have a point - all things equal I'd prefer copper, but it seems like aluminum can be fine when done right too - just riskier when done to the quick and dirty homebuilder standard.
