i've got a little baby AGZ050 air cooled package chiller being used for process. circuit one has a refrigerant leak at the TX valve. this was installed in march 04. the local office is telling me that they wont touch it. the factory tells me it is definately a warranty issue, but i must deal with the local office ( read franchise, i believe). anyone out there know the deal??????? or should i just bite the bullet and fix it myself?
