Replaced Evap coil and txv under warranty
2019 York heat pump system basically empty of refrigerant. Added nitrogen to system to try and pinpoint leak. Unit had a pretty slow leak so I was unable to hear any nitrogen leaking out but Leak seems to be coming from evaporator coil. Fittings around txv appear oily. Gave option to replace coil under warranty or just refill system with refrigerant. Customer wishes to speak with spouse before making a decision on route for repair.
