Trane split heat pump, 2 zone system. tested system at arrival and found it slightly low on refrigerant. system will cool ok during lower temps, but as it gets warmer outside, unit will struggle to cool effectively. performed a leak search and found that the evaporator coil is leaking. quoted customer 3 options: to add refrigerant and sealant, replace the evaporator coil, or replace the entire system. customer would like to think over the options.
