    Good diagnostic and repair. That condenser could still be in operation!

    Great detective skills! In today’s world it’s all about selling new
    equipment and that’s a shame. We have very few techs that can actually fix
    anything or would want to take the time to fix something. You are one of
    the few that do it right. Good Jo

    I feel the same as eleverich. Right on with that statement.

    Tips! For small leaks sometime I used “spray nine”

    Are you using it to clean the tubing? GFM

    Very good video!! What are you using to braze the repair? Is that a solder
    or bronze rod?

    I use 15% Sil Phos. It is a high temp brazing compound. I believe it melts
    between 1400 and1600F. I stay away from 5% or less especially for older
    tubing as I haven’t had good experience with it. Thanks for the comment. GFM

    The unit was only 5 or 6 years old. Everything on it looks like new. GFM

    Great repair, I also have repaired a bunch of leaks like this after people
    who recommended to replace the unit or complete coil, I have worked around
    guys if the leak is in the coil they say replace, good thing I enjoy going
    behind these techs and repairing the leak, I got to admit though the tubing
    in the coils are very thin and very easy to make a bigger mess if you don’t
    know what you are doing, I agree with you on the 15% silver I don’t care
    for anything below that, or the dye either!!

    I’m with you on all that. As to the thin tubing, that is our job. If we
    only give up on the tough ones, why are we service techs. Thanks for the
    thoughts. GFM

    The issue of oil loss is, I think, overrated. A very small amount of oil
    makes a very big slick. Thanks for the comment. GFM

    That is a nice looking condenser! Most of the ones I see are filled with
    junk/leaves/dirt and are corroded to hell. I would be proud to install that
    one in my own home! Its a shame they scrapped it rather than repairing it.

    Yes. This one is quite new. I would never throw it away. GFM

    Nice repair! did you never had problems with the other tubes when your
    heating the leaking pipe?

    would it be adequate to flood the system with co2 instead of nitrogen?

  17. grayfurnaceman
    Posted April 19, 2013 at 3:53 pm | Permalink

    I often times use CO2 as it is an inert gas like nitrogen. So yes it works
    fine. GFM

    I agree that a repair on this unit may have been the right thing to do.
    There are a couple points that I think should be made. I noticed the copper
    lines touching on the header. I also noticed that someone had left the
    bolts out the compressor feet. The compressor moving around is one good
    reason this could have happened in the first place. The other thing is that
    there is no need to cut the end plate. You can take a screw driver and
    hammer and tap the plate right back toward the fins.

    Nice Repair! Not any easy thing to do; like you said thin wall tubing is
    delicate stuff. That unit looked all shiny and new to me. I certainly would
    question the tech who opted to replace instead of repair. Not everyone is
    so diligent I suppose…

    I try never to condemn work unless its a safety issue because I don’t know
    what the tech was up against. However, it does seem a shame to replace it.
    Thanks for the comment. GFM

    We almost never hack up the coil fins to get at the joint. But if u have
    to….also we have blown adjacent elbows with the heat. A good leak
    detector helps. Once a year to rapair recurrent leaks.
