Energy Star-rated roll-in refrigerators offer savings in energy and utility costs. 

Energy Star roll-in refrigerators are approximately 30 percent more energy efficient than standard models and can save between 590 and 730 kWh per year, depending on the model. This adds up to $60 to $70 in annual savings or a lifetime savings totaling between $560 and $700.

In addition to cost savings, these units offer uniform cabinet temperatures, reduced heat output due to a more efficient compressor system and fan motor and an extended service life.

Other roll-in features that may save energy include improved insulation and components such as high-efficiency compressors and motors; improved coil designs; variable speed fans, improved fan blade designs; anti-sweat heaters; improved gaskets; and more efficient interior lighting.
