Installing AC in my house.. picked up the coil and checked it out before I hauled it up into the attic..

What’s going on here?

Did they puncture it and then braze it shut?

The loop next to it has some wrench marks on it and it’s bent.

I’m thinking I’m gunna return it and get another one.


The coil had pressure in it, but sounded less than usual. Or maybe I’m just paranoid LOL

    Or in this case, return it.

    Sure looks like a repair of some kind. If it was a paying customer, back it goes. If it was in my own house (& no real damage), I'd probably keep it, just because the supply house takes care of me & it's nice to return the favor from time to time.

    Was there double tape on the box, like it was opened and resealed? Those brazes don't look like part of an Autocad layout program. Full refund, and an apology.

    Probably leaked on thee initial test and they fixed it. That's what manufacturers do. There not going to toss a coil if they can help it.

    It's probably ok, but why take a chance? I would return it

    Looks like a joint that leaked during testing at the factory and was redone.
    Personally, I don't think you'd have an issue since it would have been retested at the factory. I'd install it and pressurize the system with at least 450 psi of N2.

    If you installed a condensing unit and it leaked where you brazed the line set on it, would you condemn the unit or re-braze the joint?

    I returned it and got another one with no patch jobs..

    I trust that it held pressure but I’m not trying to change out a coil in my tight attic in the heat of summer because of something i could have prevented.

    The newer one looks good and will hopefully never leak! Ever!

    Now I just gotta find the time and energy to get up there and install it!
