Each of the coils we build are custom built for you. Even our in stock items are only partially prefabricated. Our coils are cut, assembled, and brazed to your specifications. In many cases, the coil you order will be the last time we build a coil with those dimensions.
It is for that reason that we do not accept returns or refunds. Given that we cut, braze, and expand metals to build your coil, it is nearly impossible to recover any part of your coil for another order, aside from recycling the materials.
