    unless the leak is on a return bend solder joint, which is common, or a self inflicted wound from an overzelous store employee trying to defrost the coil themselves, coil replacement is usuall the beast way to go, aluminum or copper. the hose clamp is a means to keep the case online until the new coil arrives.

    you know lost sales prevention is your best sales tool in a market

    Get an old dirty oily greazey slimey aluminum coil somewhere, punch a tiny hole in it and make your attempt at reapiring it.

    practice on coke cans or beer cans. they are thinner than the coil tubing. if you get good a beer cans the coils are much easier, unless they have been fouled with deli oils or the like. in that case try the epoxy. that works great, and that is actually what holds the return bends on the end of the Hussmann coils. DO NO TRY TO SOLDER ON THAT END OF THE COIL. IT WILL RUIN THE EPOXY JOINT.

    Another temporary fix on the coils that are multiple circuit is to eliminate that circuit of the coil at the distibutor inlet and the coil outlet, which are copper. cut em and pinch em. again temporary fix until new coil arrives

    Ever seen a distributor with 16 lines all aluminum and all aluminum evap? Had a broken line @ head, maybe 1/4" stub. Oh, the distributor was facing directly down. Epoxy does not work, hired a welder to finish job. Removed that 1 line from circut.

    It's just that thought of the hose clamp and rubber patch idea is just so primitive........but hey, whatever it takes is right if the "suits" in charge won't tolerate any downtime. If I were sufficiently pressured I might have even tried the J/B Weld or some similar miracle fix, but I wouldn't give it more than a "tail light" guarantee.

    The market biz is truly strange in that they can be so cost conscious on the one hand and be so free with a buck on the other. A chain will have a hieracrhy of managers, area supervisors, directors, zone vice-presidents, etc that can really make life hectic if your sitting in the middle of the pileup.

    An independent operator will want to weigh the cost vs the lost profit potential and give you a straight answer like.......OK, I'll just set this case up as a dry display for now and wait the three or four days for your coil to get here by truck.

    The chain will want a man there dumping refrigerant into the system 'til the cows come home while the new coil is special handled air-freighted/courier delivered from the factory to the store for arrival late that night. The cost difference could be $20,000 but they don't care......don't shut down that case.

    OK.....Go ahead and patch it, fix it, whatever.....It all really depends on who you answer to, what they expect from you and what thet are willing to pay for.
