Start with the opening and the configuration
Confirm the finished cabinet opening, not an early drawing. Refrigerator columns, freezer columns, bottom-freezer units, and side-by-side pairs use space differently even when their nominal widths sound similar.
If you are replacing an existing built-in appliance, record the model number and the full cutout. Do not assume a new 30-inch unit will use the exact same clearances as an older 30-inch unit.
- Finished opening width, height, and depth
- Door swing and hinge side
- Single column, paired columns, or combined unit
- Panel-ready or visible appliance finish
Coordinate panels, handles, and reveals
A panel-ready appliance usually does not include the decorative cabinet panel or handle. The cabinetmaker needs the current installation template, panel thickness and weight limits, toe-kick strategy, and reveal plan.
For a display or used unit, confirm whether any mounting hardware remains with the appliance. Missing brackets or trim can delay installation even when the main unit is in excellent condition.
Verify power, water, ventilation, and floor level
Check the manufacturer installation guide for the exact electrical and water requirements. The outlet and shutoff must be placed where they will not interfere with the appliance body, anti-tip hardware, or service access.
Built-in units depend on correct ventilation and a level, load-bearing floor. Resolve those details before delivery, especially in a remodel where cabinetry can hide earlier conditions.
Plan the entire delivery path
Measure doors, elevators, hallways, corners, islands, stairs, and the final approach. Include packaging dimensions when available. A unit that fits the opening may still be impossible to move through the home safely.
- Narrowest doorway and hallway turn
- Elevator door and interior dimensions
- Stair width, landings, and railings
- Protection required for floors and walls
- Removal path for the existing appliance
For used and display units, buy the individual item
The model specification describes what the appliance was designed to do; the condition report describes the exact unit being offered. Ask for current actual-unit photos, known cosmetic notes, a power-on or functional inspection summary, included parts, and the applicable written warranty and return terms.
Availability for a one-of-one unit should always be reconfirmed before payment or scheduling trades.
