Gilbert Arizona, performing a scheduled maintenance on a train split furnace and straight cool unit inspected in cooling mode. I recorded the indoor temperature split, indoor static pressure, indoor blower amp draw, inspected indoor blower wheel and indoor compartments and indoor coil, checked and flushed drain pan and drain line. Checked refrigerant pressures, tested amp draw of compressor and outdoor fan motor, tested capacitors. This unit is operating properly and efficiently. Thank you!
