Came out to a no heat. After diagnosing the system we found that the 2018 goodman R410a system was wired incorrectly. We found that the wiring was wrong at the indoor and outdoor unit. We also found that the zoning board was wired wrong as well. We recommended that the customer have the system wired properly so that we can further diagnose the system. After adding on a transformer and continuing to diagnose the system we also found that the zoning board is not sending voltage to the out door unit. The zoning board will need to be replaced in order for the system to function correctly. The outdoor unit is also making a very loud sound as I manually engaged the contactor to check pressures.
