Ac repair: pressures were 410/140 on the upstairs unit which indicates a restriction in the line. Removed the sensing bulb from the suction linenand pressures normalized at 322/160, which indicates a restriction at the TXV metering device. Recommend replacing TXV, unit is potentially under warranty. Will verify warranty status on Monday 8/10. Furnace board for downstairs unit has a malfunctioning light, not giving normal flash codes. Recommend replacing control board as well.
