Column built-ins, BI/ICBBI series, Pro 48, integrated drawer refrigeration. Engineered for 20 years; we know the service patterns.
Sub-Zero is the North American standard for built-in residential refrigeration. Their dual-compressor design (separate fridge and freezer systems) is unique in the industry and engineered for 20+ years of service. In Toronto, you see Sub-Zero in Rosedale, Forest Hill, Yorkville, The Kingsway, Bridle Path, and high-end downtown condos. Most repairs we do are electronic — thermistors, control boards, user-interface boards — rather than anything mechanical. The sealed systems rarely fail.
BI-36/BI-48/ICBBI series — thermistors drift over 10+ years, fridge runs too warm or too cold. Routine replacement, parts widely available.
After 10–15 years gaskets harden and leak cold air. Replacement + hinge adjustment.
Noisy fan or inconsistent cooling — fan motor bearing wear. Serviceable without breaking the sealed system.
Display goes dark or misreports temperature. UI board swap is straightforward.
Column and BI-series ice makers — standard maker assembly, water inlet valve.
Clicking but not starting — relay fault, not compressor itself (usually). Quick swap.
BI-36, BI-42, BI-48 (built-in side-by-side and French-door); ICBBI (integrated); IC-27, IC-30, IC-36 (column fridge/freezer); PRO 48; UC/UU (undercounter refrigeration drawers); 700 Series (classic).
Not usually. Thermistors, fans, gaskets, and control boards are all routine repairs at routine prices, not the catastrophic numbers people fear. What does get expensive is sealed-system work (compressor, evaporator, refrigerant) — and on a 20-year-old unit that may not be worth it. We tell you straight after diagnosing on-site.
Often yes. Sub-Zero BI and 500 series from 1995–2005 are some of the most durable refrigeration ever made. Electronic and mechanical repairs usually make sense on these units; sealed-system work on a 25-year-old unit is a closer call. We quote case-by-case after on-site diagnosis.
Yes — we’re equipped for both brands and they’re frequently installed together. Single visit covers fridge + range.
Excellent. Sub-Zero Canada supports current and most legacy parts. 1–5 day ordering.
