repair of an aluminum coil
does anyone know the best way to go about soldering an aluminum coil? i have a situation where a customer has a trane condenser coil that has three pin hole leaks in the aluminum tubes.the coil is under a ten year warranty,but the coil trane will not have until after aug. 20.that is way too long for someone to be without ac in the summer. i don't know what good having such a long warranty is,when something goes wrong it takes so long to get the parts.any suggestions will be much appricated.thanks
