The problem we've got is the kids bedrooms are in an attic conversion, and last week it was mid 30s up there overnight, so they had to sleep downstairs. This doesn't sound like a big deal, but one of my kids is at the severe end of autistic and any minor change to the daily routine causes chaos. So we need one up in their bedrooms to make them habitable. Our house is a listed building, so we can't have "proper" air con with massive external units unfortunately. It's probably not great for the collection either but people are the main priority
