    Replace suction core inside evap coil

    On the first visit the tech found the 3 ton home heat pump unit low on refrigerant. He added refrigerant and dye detector. Came back in two weeks and charged $ plus two lbs of refrigerant and made the following diagnosis. "Replace suction core inside evap coil". I don't seem to be able to find that part description on line. The leak test did show green on the schrader valve.

    The larger line of the indoor coil may have a Schrader stub with a cap on it ( if it’s not being used ) and they changed the core assembly? If that’s where an actual leak came from. Think bicycle tire or car tire, something similar to that. If you can’t find it ask them where exactly is it located.

    What brand coil do you have as if a Goodman, they have one on the suction/vapor line typically.

    Probably won't find that part online, that part is only listed in the "Todays Sales Tech Manual".

    They could probably just put a decent cap on it. Anytime I install a Goodman coil I removed the cheap plastic cap that comes on the Schrader port on the suction line inside the evaporator compartment and put a little bit of refrigeration grade assembly lubricant on the seal in my nice brass cap and put it on there so I don't have to worry about leaks.

    I'm tired of these mediocre "semi flammable" refrigerants. If we're going to do it let's do it right.
    Unless we change direction we are likely to end up where we are going.

    Call them back and ask for a better description!

    How I read it, is that during the first visit he diagnosed the system low on charge and added refrigerant and dye to the system.

    On the follow-up visit he located the leak (signs of dye) at the suction schrader valve, I assume that he charged you to replace the schrader valve's leaky core.

    Some of these indoor coils have a suction schrader valve where a TXV's equalization line may attach if a field TXV was to be installed. I am imagining that your system probably does not use a TXV, but a piston restrictive device instead, leaving that schrader valve port open and that was what was leaking from its core?

    This is my educated translation from the what the OP is trying to say.

    As for part description, may want to contact your technician and have him explain a bit more clearly the service he performed.
