I have a large Viking stainless steel range hood in great shape over my 36" Viking range. As my design ideas have broadened, I would like to change this to a painted tall rectangle hood. I'm not sure who I call to do this? Do I have to throw away/give away the current hood and fan inside and start all over? Can I disassemble the pieces and reuse any of them? Should I just buy the whole thing off Hoodsy? Thank you all!
