They charged by weight. Done. No pressure measurement or readings of any type that I could see. They used the gauge set to get the 410A into the outdoor unit (compressor) but I didn't see any adjustment of pressures/etc. like balancing the sub cooling and super heat and all that business.
Roger that - re. a leak detector - I was thinking of getting one. Been reading about the different types.
The line sets are attached to the indoor units and outdoor unit via flares. During the pressure test of 600psi they found a bad flare and then redid the pressure test. The one thing I didn't like was brazing lines together up in the attic when I specifically asked to not have that.
