Repair or Replace?
Age
What's the age of your Sub-Zero? If it is 16+ years old be very cautious on how much you are
going to invest in servicing a unit that may only have a couple years left until the next repair or
replacement. Keep track of all service history so it is easier to calculate cost over the years. At
the same time, a new Sub-Zero will cost $7,500 - $10,000, so repair could be a good option.
Sub-Zero Cost
Sub-Zero's have evolved over the years, from the first single compressor designs that were
thermostat controlled and not as efficient to operate. Sub-Zero products since roughly 1995 are
computer controlled and have twin compressors on select models. They are now more efficient,
preserving food much longer than other fridges in its class.
Repair Cost
Always ask for a completed job price, rather than time and materials. Time can be skewed and
the repair will be over budget. If you are heading towards 40% of the units cost in total repairs
you may want to consider replacement.
