Installed new A/C and removed the old one. Set a new pad down and leveled it. Flushed the line set and put pressure on it to 400 psi. Sucked it down into a vacuum to 235. Release the charge and did a start up. Installed a new humidifier and put the control downstairs. Ran a water line and a drain for the humidifier. Tested it to make sure it was working
