NO, you want a txv if you had one. Why is he replacing the whole coil and not just a txv?

he is changing the whole coil because when he did change the tvx it was leaking right from the manufacturer i guess. He harped at supplier and supplier said he would send brand new coil evap.look we are getting terrible heat here 40c with humidex.also supplier sent evaporator with metering piston too big cause it was all he had in stock and would send right metering piston in a couple of days.hvac thec said supplier tech said it would not make much difference in cooling mode.now my heat pump is cooling only hvac tech said compressor is flooding a bit by his pressures.not only is suction line sweating but compressor is also sweating.QUESTION ,can this damage my compressor. THANKS IN ADVANCE

The one that the manufacturer spec'd for it..... If they spec'd a piston instead of a txv.
