The UL/CSA/ETL listing should still work. Of course it could *really* be a
fly-by-night outfit and not listed, but it's worth a try.

The component that matters most is... the compressor. Try and
figure out who made that. If it was US made, it was probably
one of only a handful of companies. Of course, it could be
an Asian import too.
