After three other companies tried to sell me on a replacement unit at a cost of over ten grand, thankfully I was referred to Legacy Air. Dave came out and recommended we try and find the leak via dye. A few months later they found the leak at a coupling joint which was an easy fix with some solder - total cost less than $300. Thank you for your honesty and for saving me over $10,000. There is no other company I'll use moving forward.
