Our (recirculating) cooker hood fan has packed up. It makes noise but there’s *no* suck. We’ve changed the charcoal and the filter but no joy, so we want to replace it. (It’s built into wall units that run the length of the kitchen).
We want one that extracts to the outside and the cooker is on an outside wall so in theory it’s a fairly simple coring job. But we have a 2nd floor flat so the external fixings can’t be done without a treble ladder, or maybe scaffolding. But next Summer there will be scaffolding up for roofing works, which presumably an installer could use.
My question is simply: could we buy a new hood now and get it installed in recirculation mode, then switch it to external ducting next year? Or is it impossible to change the mode once installed?
