I know on cars brake lines will leak if you don't double-flare them.
Is the pressure in an AC system that much lower that a single-flare
won't leak?

Probably. I'm not sure what typical AC pressures are in a residential
system but I am guessing somewhere in the hundreds of PSI range.
Automotive brake systems can run at 2500 PSI or even more during a
panic stop.
