Hello, I have moisture/condensation on the ductwork that was installed when your crew replaced my unit in Dec. It is flex duct. At the time, I was told that is would be replaced later with metal. I understand that flex is now widely used and that is fine but it is not sealed well. Very cool under the home with the ac on and like I stated there is condensation on the duct. Has to be leaking some.
