Need help on my eva coil

Hello,

I have no idea about the AC, duct etc.

The repairman said that my eva coil is leaking and need to be replaced. This is 9 yrs old house. He also charges $225 for duct modification and $95 for disposal of the coil.

I have American Home Shield insurance on the AC unit with labor/parts and ductwork, but insurance does not want to pay the duct modification and disposal.

Are these duct modification and disposal charges right? What is the duct modification, is it part of the labor cost? Should I argue with insurance to pay the modification?

Thanks a lot!
