Repair or Replace? San Diego Appliance Guide (2026)

A plain answer for each appliance: how long it usually lasts, what a typical repair costs here, when replacing makes more sense — and why an older built-in is rarely a simple swap: the opening, the custom panels and the connections often do not match a new model.

The short version

• The 50% rule (Consumer Reports): if the repair costs more than half the price of a comparable new appliance, replacement usually wins.
• Age matters for mass-market appliances: past about half of the expected life (InterNACHI chart below), lean toward replacing when a major part fails.
• Built-in and panel-ready appliances are the exception: Sub-Zero says its products are designed to last about 20 years on average, and the true cost of replacing a built-in includes the opening, new panels and often new connections.
• Energy counts for old refrigerators: ENERGY STAR says a refrigerator over 15 years old can cost about $95 a year to run and uses about 20% more energy than a new certified model.
• The part matters more than the brand: fans, pumps, igniters and switches are cheap; sealed systems, tubs and bearings are not.

Ranges are typical, not quotes. After the $99 residential diagnostic (credited toward the repair) you get a written quote before any work begins. Full price tables: pricing page.

Why an older appliance is rarely a drop-in replacement

The price of a new unit is only part of the replacement cost. Appliances built 10–20 years ago were made to openings, panel systems and connection points that current models often do not share. This is the part of the decision that most guides skip, and it is where we see San Diego homeowners spend the most unplanned money.

Built-in refrigerators: the opening and the panels

Built-in refrigerators are made to a cabinet opening, and the opening changed between generations. Sub-Zero’s own compatibility notes say that replacing a 500-series or 200-series unit (models 601F, 601R, 215R) with a current Classic Series BI-36 model requires an additional 11 inches of opening height, that the electrical location is different, and that the old door panels will not fit because they are too short and narrow. Replacing a side-by-side with a French-door model (for example BI-48S to CL4850UFD) needs two door panels plus a drawer panel, framed panels are no longer an option, and new custom panels must be made. Some overlay panels do transfer with a retrofit kit (BI-42S to CL4250S), but framed handles do not fit because the doors are taller. In other words: for most built-ins older than one generation, a “replacement” means new cabinetry work, new custom panels and often a new electrical location — before the price of the unit itself.

Panel-ready dishwashers: the panel is cut to one model

A custom dishwasher panel is made to the exact dimensions, mounting pattern and weight range of one model. Whirlpool and KitchenAid specify that a customer-supplied panel and handle together must weigh no more than 16 lb and be cut to specific dimensions, and recommend a cabinetmaker for the job; Bosch models accept panels from 7 to 24 lb and the door springs are set to the panel weight; Asko’s panel height depends on the opening and must be at least 28 inches. A new dishwasher from another brand — and often a newer model from the same brand — needs the panel re-drilled, trimmed or remade, and the handle may land in a different place.

Wall ovens: the cutout was made for the oven you have

A wall-oven cutout is cut to the oven that was installed when the kitchen was built. Manufacturers ask you to measure the cutout width, height and depth before buying a replacement, and sell filler trim kits for the common case where the new oven is shorter than the old opening. A different cutout means a trim kit at best and cabinet rework at worst, and a double oven or oven-microwave combination from another generation almost never lines up.

Cooktops and ranges: the countertop decides

A cooktop cutout in granite, quartz or tile cannot be made smaller. The new cooktop must be at least as large as the old cutout, so a 36-inch cutout cannot take a 30-inch cooktop without a new countertop. Pro-style ranges differ in depth, height and backguard, and a 36- or 48-inch Wolf, Thermador or Viking range sits in a space built for it; a different brand usually means adjusting the filler strips, the island trim or the hood clearance.

Laundry: stacks, closets and laundry centers

Stacking kits are brand- and series-specific, closet installations have fixed depth and door clearance, and a 27-inch one-piece laundry center from an older generation has no direct replacement in many lines. A new front-load pair is usually deeper than a 10-year-old pair, and in a closet that difference decides whether the doors still close.

Every category: connections and clearances

Water-line and electrical locations move between models, door swing near an island needs clearance that older kitchens may not have, and venting for a dryer or a hood is fixed in the wall. These are the items we check at the diagnostic before we tell you a replacement is “easy”.

What to measure before you decide

Send these with your booking, or we check them at the diagnostic visit:

1. Model and serial number from the label — compatibility and parts availability start here.
2. Opening width, height and depth (built-ins and wall ovens): measure the cabinet opening, not the appliance.
3. Cooktop: the cutout size in the countertop and the material (stone cutouts cannot shrink).
4. Panels: are the door panels framed, overlay or flush inset, how thick, and is the handle part of the panel?
5. Where the water line and the electrical outlet are, and whether they are reachable without opening the wall.
6. Door swing: distance to an island, a wall or another appliance door.
7. Laundry: closet depth, stacking kit, dryer vent position and length.

A San Diego factor: coastal air

Near the coast — La Jolla, Coronado, Del Mar, Pacific Beach, Oceanside — salt air speeds corrosion on condenser coils, fan motors and wiring connectors. Corrosion alone is rarely a reason to replace; cleaning and replacing a corroded fan or connector is usually inexpensive. It becomes a replace decision only when corrosion has damaged the sealed system of an older mass-market refrigerator.

How we help you decide

We diagnose first and tell you plainly when a repair is not worth it — before you spend money on parts. You get the cause, the repair price in writing, a fit check of your opening and panels if you are considering replacement, and our honest recommendation. Repairs carry a 90-day labor and 1-year parts warranty.
