A remodel checklist for built-in refrigeration

Pick the appliance before the cabinet drawings

The rough opening for a built-in is dimensioned from the specification sheet of one particular model, not from a category. A 36-inch over-and-under, a 42-inch unit with an ice maker, a 48-inch PRO with its exposed condenser, and a pair of integrated columns are four different openings with four different heights, clearances and utility positions. Put a generic rectangle on the drawing and choose the appliance later and you end up either shimming a gap or cutting finished cabinetry on the day of delivery. Decide the model, print its installation instructions, and give that document to the cabinetmaker, the electrician and the plumber, not only to the appliance dealer. Decide the hinge side against the real traffic path rather than by what looks symmetrical on the elevation. And count the secondary equipment now: refrigerator drawers in the island, a beverage center behind a bar, an undercounter ice maker in an outdoor kitchen. Each is its own opening, its own circuit and sometimes its own drain.

• The exact model number, not a category and not just a width
• The installation instructions in the hands of every trade, not only the dealer
• Hinge side decided against the traffic path in the room
• Custom panel or factory stainless decided early, because it changes the trim and the load on the hinge
• Every undercounter unit drawn on the same plan as the main built-in

The rough opening, and the mistake that traps the unit

Width and depth usually come out right because they are visible on the elevation. Height is where kitchens go wrong, because the height on the spec sheet is measured to the finished floor. If tile, underlayment or engineered wood goes in after the appliance is set, the opening has quietly lost part of an inch, and the doors bind on the counter or the unit will not go back in after a service call. The related error is flooring that stops at the front of the unit instead of running underneath it. That leaves a step the appliance has to climb, and a built-in is heavy enough that dragging it over that lip is how flooring gets chipped and toe kicks get torn off. Run the finished floor under the whole footprint. Then check the door swing against any return wall, because a door that cannot open past ninety degrees means the crisper drawers and freezer baskets cannot come out at all, which nobody discovers until the first time they try.

• Height taken to the finished floor, after underlayment and tile
• Finished flooring run under the full footprint so the unit can roll out level
• Delivery path measured: doorways, turns, stair widths and thresholds
• Door swing clearance at a return wall, checked against the drawers coming out and not just the door opening
• Floor structure able to carry the weight where a heavy built-in sits over a long unsupported span

Power, water and drain: run it while the walls are open

This is the cheapest hour of the whole project and the most expensive one to skip. Each refrigeration unit wants its own dedicated circuit, sized and placed as its installation instructions specify, and the receptacle wants to land where those instructions put it, generally somewhere reachable without pulling the appliance out. Your electrician will know what the current code cycle requires; the point is that they should be reading the appliance document rather than guessing. Water is simpler and gets ignored more often. Put a quarter-turn shutoff in an adjacent cabinet where a person can reach it in the ten seconds they will have when a line lets go, label it, and use a braided stainless supply line. Do not accept a self-piercing saddle valve on the cold line: they scale up, they weep, and every one of them is a leak with a date on it. Drains have to be settled before the floor closes. Some undercounter ice makers need a gravity drain or a pump, and if none is roughed in, the model list narrows to drainless machines and the decision has been made for you by omission.

• A dedicated circuit for each unit, positioned per the installation instructions
• A receptacle reachable without pulling the appliance out of its opening
• A labeled quarter-turn shutoff in an adjacent cabinet, not behind the unit
• Braided stainless supply line, and no self-piercing saddle valve anywhere
• A drain roughed in for any undercounter ice maker, decided before the floor closes up
• Outdoor-rated equipment for an outdoor kitchen, and nothing indoor pressed into service outside

Air: the clearance that gets designed out

A built-in rejects the heat it takes out of the food through a condenser that breathes at the bottom front, behind the grille. That grille is a functional part, not a decorative one, and it is the first thing a beautiful kitchen tries to hide. A valance built across it, a deep counter overhang, a filler panel added late to close a reveal: all of them cost the machine air, and a machine short of air runs longer and hotter and quietly shortens its own compressor life without ever showing a fault. Undercounter equipment is worse, because a drawer unit dropped into a sealed island cavity with a solid toe kick has nowhere at all to send its heat. On a warm afternoon it runs continuously and still loses ground, and there is no component in it to replace, because nothing in it is broken. Give every undercounter unit the ventilation its spec sheet asks for, then think about adjacency. Very few houses in this neighborhood have central air conditioning, so the temperature around a cabinet is whatever the day is, and a design with the bare minimum clearance has no margin left on a warm September afternoon.

• Nothing built across the grille: no valance, no trim, no late filler panel
• A ventilated toe kick or rear panel for every undercounter unit
• No refrigeration boxed into a sealed island cavity
• Wine storage kept clear of dishwasher vents, oven exhaust and direct west sun
• A look at what sits on the other side of the wall behind the unit

Panels, doors and the alignment nobody checks at handover

A custom panel is a load hanging off a hinge, and every model publishes a maximum panel weight and thickness. A cabinetmaker who was never given that number builds to the aesthetic instead, and a panel over the limit produces a door that sags a few weeks after handover. The top corner of the gasket stops sealing, warm humid air starts entering the cabinet there, and within a season there is frost on one side of the freezer and an owner convinced the refrigeration has failed. Handles matter too: check at full swing that the handle clears the adjacent wall or the perpendicular run of cabinets, or the door stops short and the drawers behind it stay captive. At handover, do not accept doors that visibly sit proud of one another, and test the seal yourself. Shut each door on a dollar bill at the top, the bottom and both mid-heights and try to draw it back out. Even resistance the whole way round is a sealed door. A point where it comes away with no grip at all is a leak you will be paying for in frost and run hours for years.

• Panel weight and thickness inside the model's published limit, given to the cabinetmaker in writing
• Handle clearance checked at full door swing against walls and perpendicular cabinets
• Reveal and shim allowance designed into the opening rather than improvised
• Doors leveled and aligned at handover, not left for the first service call
• Every door seal proved at four points before the installers leave, not after the first summer
• The grille panel fitted so it still comes off for cleaning without dismantling trim around it

During construction, and the first month after

More built-ins are damaged by the remodel than by the ten years that follow it. Drywall sanding and floor finishing produce the finest particulate a condenser will ever meet, and a unit energized and running through that phase can have a coil packed solid before the kitchen is finished. Keep it off and covered until the dust has gone, resist the urge to use it as the jobsite refrigerator, and book a condenser clean for the week the trades leave regardless of how careful everyone says they were. If it has to stand unpowered for more than a few days, leave the doors ajar so it does not develop the smell and the mold that never entirely go away. When the kitchen is handed over, commission the appliance properly: level it, run it empty for a full day before loading it, then verify with a thermometer rather than the panel that the fresh food compartment holds 38°F and the freezer 0°F. Discard the first two or three ice harvests and run the water until it is clear, because the line and the mold both need flushing.

• Unit off and covered through drywall sanding and floor finishing
• A condenser clean booked for the week the trades leave
• Doors left ajar if the unit stands unpowered for more than a few days
• Run empty for a full day, then verified with a thermometer at 38°F and 0°F
• First two or three ice harvests discarded and the water run clear
• Data plate and shutoff valve location photographed and kept with the house documents
