Maybe this should be posted somewhere under kitchens, but I wasn't sure.
We are remodeling the kitchen entirely. We have a funny, old-style fan mounted in the wall which is vented to the outside and opens and closes using a beaded pull-cord (see attached photo). We are wondering what our options are for upgrading. We don't know whether to go with an over-the-stove mounted microwave or just a regular hood, and with any of those options don't know how to reconfigure any venting to the outside that has to happen. Can the existing hole be used or does something new need to be cut which is situated a little higher? We'd like to avoid cutting new holes if at all possible because we don't know how the current hole would be patched up given that we have aluminum siding outside. Any advice for how to upgrade our current cooktop venting set-up? Thanks.
