Found at 30° outside suction line was 68°. I think it should be well over 110° at 30° outside. Check pressure transducer to pressure on gauges pretty close within four psi transducer are good. I suspect a leak somewhere. I tried to force the Bosch into high and the Hertz stay at about 46. Must do a leak search on system to verify leak location. Searched evaporator coil for leak found nothing leak search heat pump. Found leak on true suction bracket. This is nothing that we can fix in the field that is welded onto the bracket that mounts to the shell of the heat pump. Added refrigerant to give heat suction line temperature was 110 should be fine until we can come back and replace that part. Also found a section of return duck that doesn’t have any tape on it. Which is sucking air in from the attic, not helping the situation when we return. We’ll go ahead and get that sealed up.
