How is the freon recovered out of dehumidifires? there are no service ports on them at all every single copper tube is soldered and one short one is crimped and soldered shut. Im assuming the crimped one is where it was filled but how would you open the system without cutting one of the tubes? So far the 2 I have broken down were already empty due to damage to the condenser coils but im sure Ill get a full one sooner or later.
