In St. Johns the Sub-Zero refrigerator install base runs heavily on 600 / 700 / BI / IT integrated / PRO 48. Our work here is sealed-system diagnostics, defrost-circuit work, and condenser-coil service — finished on the first visit when the model is confirmed at booking. Most-common call: the 648 / 650 ice-buildup pattern traced to defrost thermostat or ribbon connector. Service routes through Switzerland and CR-210 estate construction touch this combination often enough that the common parts ride the van by default.
