Rigorous Testing Promotes Long Life and Owner Satisfaction
Our commitment to quality and performance includes scrupulous testing of each individual unit before they leave the factory.
Every major component from switches and lights, to fans and the control board also must pass a performance inspection
before they can continue to the production line.
Component parts are also subjected to stress tests in extreme
conditions of temperature, vibration and electrical variance. These simulated lifespan assessments ensure
switches and lights are cosmetically and functionally sound for the lifetime of the product.
We don’t stop there;
one third of the units are also given a final 18-hour battery of checks, just for good measure — all with the
goal of making Sub-Zero products last not just for years, but for decades.
