It really doesn’t matter what system you deal with. All refrigerant systems operate under huge pressure and temperature swings including ambient continuously.
Yes but auto systems swing hundreds of pounds in seconds. Which is from having an unstable rpm drive motor (the engine in this case) Ambient temps do not change that quickly to cause the same issues. Home systems are also brazed at most all couplings where auto systems have spring locks with o-rings/stat-o-seals. The systems operate similarly but have different failure types. Temporary leaks in auto systems are common. It happens for any numbers of reasons.
Y'all are right though, I've only serviced hundreds of cars. I don't know what I was thinking.

Ever hear of this thing called a heat pump? If you have you wouldn’t be questioning massive instant pressure reverse. We even have these things in our field called service ports with schrader valves, compression and flare fittings. While silver is a large part of our work not the only method.
