Their RMA policy leaves a lot to be desired, especially when dealing with Navien equipment. They charge you up front for the replacement, then wait until they have "enough" Navien returns before shipping back to the manufacturer in California. Was told it can take up to 90 days before you get reimbursed. The warranty repair for our customer was done on October 27. They still haven't sent in the old heat exchanger yet and it is December 8th.
