Responding to this call because of no AC. By checking the unit I was able to find the issue. A wiring that controls the 24 V power leading to the outside unit and become disconnected most likely due to vibration of the fan motor. I resecured it and after checking, refrigerant levels to make sure they were in the green. I noticed a Schrader valve was leaking so I replace that as well. Everything is covered under warranty and installed by us less than a year ago
