I have actually seen water boiling at room tempature.I once worked in a lab
and saw it done. Water boils at a lower tempature at high altitudes(low
pressure)and food needs to be cooked longer there.

 How else,other than blowing with compressed air, is a/c flush gonna be
blown out from hoses? Mineral spirits or $50 stuff. Avoid flushing? I think
residual  mineral spirits will be drawn out by boiling ,too. A nice clean
home for the r-12 (or what-ever).
