Manufacturer Trane Model # 4TWR5030H1000AB Serial # 220947T74F Completed a preventative maintenance on a newly installed Trane system. I changed the 16x20x1 filter. Then I took a split temperature of and it was 20 degrees. Then I water tested the drain it was working. Then I went outside and performed a amperage readings on the compressor 4.3 amps and on condenser fan motor .45 amps both are operating properly. And the capacitor and contactor are both working and in range. System is operating properly at this point.
