Where we work
Loretto
The middle of Mandarin, and the neighbourhood this shop is named after. Established houses, remodelled kitchens, and original water lines.
Loretto sits in the middle of Mandarin, on and around Loretto Road, and it is the neighbourhood this shop took its name from. It is not the riverfront and it is not the newer southern end. It is the settled middle: houses put up mostly through the 1970s and 1980s on lots big enough for real trees, occupied long enough that most of the kitchens have been changed at least once.
That last detail is the one that determines what we find when we open a cabinet here.
Second-remodel kitchens
A house built in 1978 was not designed around a 36-inch built-in refrigerator with a custom panel. When one went in — usually in a remodel somewhere between the late 1990s and the 2010s — the opening had to be made, the cabinetry built around it, and the services brought to it. Twenty or thirty years later, the appliance is being replaced or repaired, and everything around it is still the work of that earlier job.
The recurring consequences are practical rather than dramatic:
- The water line is original to the remodel, not to the appliance. A copper or plastic line run in 1999 and never touched since has been in service for a quarter of a century. Its internal diameter is not what it was, and nothing inside the appliance can compensate for what does not arrive.
- The opening is exactly the size it needed to be. There is often no room to bring a unit forward without lifting the countertop overhang or removing trim, which affects how long a job takes and what we tell you about it beforehand.
- The outlet is where the electrician of the day put it. Sometimes behind the unit at a sensible height, sometimes in the base cabinet next door, and sometimes shared with something else on the same circuit.
None of this is a problem. It is simply the reality of working in an established neighbourhood, and it is why we ask about the remodel history on the phone rather than being surprised by it in your kitchen.
The supply line is the quiet culprit
The quarter-inch line that feeds the ice maker is the part of the installation nobody thinks about, and in a neighbourhood of second-remodel kitchens it is usually the oldest thing in the chain. It was run to suit the appliance of the day, routed behind cabinetry where nothing would ever inspect it, and then left alone. Twenty-five years later it is still there, often with its original shut-off, sometimes with a kink put in it the last time a unit was pushed back into place.
What that does to an ice maker is easy to mistake for a failing appliance. The fill valve opens for a fixed number of seconds and trusts that the right volume arrived. If the line is delivering less than it used to, the mould fills short, the cubes come out light and hollow, and the freezer temperature stays exactly where it should be the entire time. Output can halve over three or four years with nothing inside the cabinet actually wrong.
So before condemning a fill valve we check what is arriving at it: pressure and volume at the appliance, the condition of the shut-off, and whether the line has been disturbed by the last time the unit came forward. Replacing a valve that is being fed by a restricted line buys you about eighteen months and another service call, and we would rather tell you the line is the job.
Ordinary houses, ordinary access
Loretto is easy to work in. The streets are wide, the driveways are real driveways, and the appliance is usually in a kitchen you can back a hand truck into. That sounds trivial and it is not: on the riverfront and in the older in-town neighbourhoods, access alone can add an hour to a job. Here it does not, and the pricing is the same flat $129 diagnostic regardless.
Because Loretto sits centrally in Mandarin, it is also the part of our area we can reach fastest and return to soonest when a part has to be ordered. A return visit here is a short trip rather than a scheduling exercise.
What we cover
Sub-Zero built-in refrigerators and freezers, integrated columns, undercounter units, refrigerator and freezer drawers, wine storage and ice makers. That is the whole list, because that is the whole of what Sub-Zero makes — there are no Sub-Zero ovens or cooktops, and we do not work on other brands.
Loretto Cold Service is an independent shop. We are not affiliated with, authorized by or endorsed by the manufacturer, and the name refers to the neighbourhood, not to any relationship with a brand.

What we work on here
- Sub-Zero built-in refrigerator repair A cabinet running warm on one side, frost creeping across the freezer wall, or a unit that runs and runs without ever settling down.
- Sub-Zero integrated column repair Panel-ready refrigerator and freezer columns that sit flush with the cabinetry until something moves, ices up or stops responding.
- Sub-Zero undercounter and refrigerator drawer repair The small units in islands, bars and outdoor kitchens, where heat, tight clearance and a long run from the main cabinet make life hard.
- Sub-Zero wine storage repair Dual-zone units where the two compartments have stopped agreeing, humidity has drifted, or the fan has become audible from across the room.
- Sub-Zero sealed system repair The refrigerant circuit itself — compressor, condenser, evaporator, drier and charge — and how to tell it apart from the cheaper faults that imitate it.
- Sub-Zero ice maker repair in Mandarin Thin cubes, hollow cubes, a mould that fills but never harvests, and production that falls away through the summer.
Worth reading first
- Why Ice Cubes Come Out Hollow A hollow cube is a water problem wearing a temperature problem's clothes. Here is how to tell the two apart before you call anyone.
- The Condenser Is Above the Doors, Not Below The one piece of maintenance that reliably extends the life of a compressor, and the first thing we check on any cabinet that never stops running.
$129 flat diagnostic, credited toward the repair. You get a written estimate before any part is ordered or any labour begins.

We were getting a thin sheet of ice instead of cubes. He measured the fill volume, found the valve leaking through, and swapped it. He fitted a filter as well, because our water is hard enough to matter.

Water was tracking down the inside of the cabinet and freezing at the base. He cleared the drain line, found the heater that keeps it open had failed, and fitted a new one so it would not simply return.

Our freezer column was frosting at the top and the door had to be broken loose every morning. He found the vent port blocked and the seal pinched at one corner where the panel had settled over time.
