Why are vacuuming and nitrogen pressure testing important during AC installation?

Vacuuming removes air and moisture from the refrigerant lines before the system is charged — skipping it lets moisture contaminate the refrigerant, which degrades performance and can damage the compressor over time. Nitrogen pressure testing checks for leaks in the pipe joints before the system is sealed and running, catching problems while they're still easy to fix.

Both steps are specifically about catching problems before they're sealed inside a running system, which is exactly why skipping them is a false shortcut — a leak or moisture contamination that goes undetected at installation doesn't show up as a visible mistake, it shows up months later as reduced cooling or a compressor problem that's much more expensive to diagnose and fix than catching it during setup.
