Freezers typically work harder than usual in the heat as the compressor cools the freezer’s internal environment. The opposite is true in the extreme cold as the compressor will simply not kick on until the external temperature is higher than what the internal freezer temperature is set to. Garage ready freezers are built to handle extreme hot or cold environments. Some freezer models, like this Garage Ready in Freezer Mode chest freezer from Maytag, offer a dependable compressor, thick insulation and a triple sealed gasket to help lock in optimal temperatures. ENERGY STAR freezers are at least ten percent more energy efficient than the minimum federal standard and use advanced technology to deliver substantial energy savings. These freezers typically offer an improved design and installation along with temperature and defrost mechanisms and utilize high-efficiency compressors and evaporators to achieve energy efficiency.
