Built-in appliances hide their maintenance points behind panels and cabinetry, which is exactly why they get skipped. A preventive visit works through range hood grease filters, refrigerator and freezer column condenser coils, door gaskets on refrigeration and ovens, and dishwasher filters, catching the buildup that eventually turns into a service call rather than waiting for it to.
Wine storage and undercounter units get particular attention here, since a door seal or a fan losing strength shows up as a slow temperature drift long before it shows up as a failure – the kind of problem a scheduled check catches earlier than a homeowner usually notices on their own.
