I attended Dons residence in Temple as he had installed an ac system himself but needed to have the lineset brazed and the system commissioned. I supplied the fittings and brazed the lineset to the evap coil and condensor. Pressure tested system to 300 psi and vacuumed down to under 500 microns and held. No leaks and clean. Opened service ports and started up ac. Checked temps and pressures, all good. Sub cool at 9 f.
