mdf:
We need a new range hood plus ducting. We live on Wellington's south cost, and the stovetop is on a south-facing wall. The southerly is not the prevailing wind, but when we get a strong southerly, it is _very_ strong.
What did you end up doing in the end @mdf and how have you found it a year later? I have a similar setup (south facing wall, very strong southerly) and wanting to install a rangehood. Should be able to go out the soffit pretty easily, which would avoid any roof penetrations and potential leaks.
What brand and model unit did you go for? Any other feedback?
