What St. Johns's climate means for your Sub-Zero appliances
For a Sub-Zero lineup in St. Johns, heat and humidity are two conditions worth accounting for. Summer heat keeps the compressor cycling longer than the spec sheet assumes, and the humidity that comes with it feeds condensation inside the cabinet. Actual wear varies by model, installation, maintenance, and use.
