How this works

Four things worth knowing before you ring.

Empty pale refrigerator interior with one glass shelf, one wooden slatted shelf and a return-air grille on the back wall

  • Refrigeration only

    Built-ins, integrated columns, drawer freezers and wine cabinets. Nothing that cooks, so the van carries sealed-system parts instead of igniters.

  • One flat call fee

    $95 covers the visit and the diagnosis, and it comes off the bill when you approve the repair.

  • Diagnosis before parts

    Superheat and subcool, evaporator and condenser temperatures, defrost circuit continuity. Readings decide the part, not a parts catalogue.

  • Phone answered round the clock

    Someone picks up 24/7. Vans are on the road 8:00 am – 8:00 pm, seven days, and you are told which one you are getting.

A call, start to finish

Three stages, and none of them is guesswork.

  1. Close view along the edge of a cabinet door and the magnetic gasket seated in its channel

    Model number and the actual complaint

    The plate is behind the fresh-food door on most built-ins, low on the frame on a column. That plus a plain description — warm at the top, frost on the drawer, running without stopping — narrows a call before anyone is dispatched.

  2. Lower rear panel removed from a refrigeration cabinet, exposing the compressor and wiring with meter probes on the terminals

    Readings taken in the kitchen

    Compartment and evaporator temperatures, condenser and evaporator fan behaviour, defrost heater and thermistor resistance, and pressures on the sealed system when the readings point that way. Written down as they are taken.

  3. Base grille removed from a built-in refrigerator, condenser coil exposed and a round fan motor lifted out beside a dismantled blower assembly

    One number, before anything is opened up

    Parts and labour quoted together and agreed before work starts. When a cabinet is not worth the repair, that is the answer you get rather than a partial fix and a second visit.

Where the van goes

Four neighbourhoods, and everything between them.

The book of work

What gets worked on.

  • Empty pale refrigerator interior with one glass shelf, one wooden slatted shelf and a return-air grille on the back wall

    Refrigerator Repair

    Sub-Zero built-ins, integrated columns and pro-style side-by-sides across the inner metro. Sealed-system diagnosis, control and evaporator faults, and the airflow problems that show up first as an uneven fresh-food compartment.

    • Refrigerator section drifting warm overnight
    • Interior light works but nothing is cooling
    • Condenser fan silent while the compressor stays hot
  • Stainless freezer drawer pulled clear of a built-in cabinet with its white moulded liner lifted out

    Freezer Repair

    Freezer columns, drawer freezers and undercounter units that lose temperature, ice up, or run without stopping. Defrost circuits, evaporator fans and door seals are the usual starting points.

    • Everything in the drawer covered in frost
    • Freezer running constantly and never reaching setpoint
    • Loud rattle from the fan behind the rear panel
  • Black-and-white frame of a tall built-in with its base grille off, machine compartment open and a vacuum hose at the coil

    Ice Maker Repair

    Clear-ice modules and standalone ice machines that quit mid-cycle, produce thin slabs, or leave water where it should not be. Supply valve, cutter grid and drain work included.

    • No ice for days with the water supply on
    • Cubes tasting of whatever is in the freezer
    • Slush in the bin instead of finished cubes
  • Two-door wine cabinet standing open under warm interior lighting, bottles on wooden racks and a tool roll on the floor beside it

    Wine Cooler Repair

    Wine storage that cannot hold a cellar temperature, ices its evaporator, or vibrates enough to disturb the bottles — undercounter, tall and integrated units alike.

    • Both zones reading the same temperature
    • Unit short-cycling every few minutes
    • Racks noticeably warm at the top of the cabinet

From the book

What people said afterwards.

4.9 average across 1371 reviews

  • Water kept pooling under the produce drawers in our Victorian and I had been mopping it up for a fortnight. He found the drain tube frozen solid where it meets the back wall, thawed it out, refitted a heater clip that had slipped, and showed me what to watch for.

    Marcus D.Ashmont

  • Our kitchen sits at the back of a three-decker and the freezer had drifted warm with no alarm at all. The thermistor was reading low so the compressor barely ran. Swapped, and he waited while it pulled down.

    Yvette C.Ashmont

  • The undercounter unit vibrated enough to rattle bottles in a small condo kitchen. Compressor mounts had perished and one levelling foot had dropped. Inexpensive parts, careful work, and the racks are quiet now.

A call costs nothing. A visit is a flat $95, and that comes off the bill the moment you approve the repair.
