Solutions for Today's Environment

As part of our promise to create a better world, discover how Hussmann’s customer-focused solutions stay ahead in an ever-changing world of energy regulations and requirements for refrigeration equipment.

We continuously take steps to ensure compliance with all Department of Energy (DOE) and Environmental Protection Agency (EPA) standards and rules.

Every six years the DOE reviews the energy conservation standards which impact Hussmann products. Currently, display cases are manufactured to be compliant with the March 2017 DOE standards. Walk-in cooler/freezer components (WICF) have compliance dates of June 2017 for doors and 2020 for refrigeration. Hussmann and CRD WICF doors manufactured today are compliant with the most recent federal standards (June 2017).

The EPA has finalized a rule under the AIM Act Technology Transitions subsection that restricts the use of certain high Global Warming Potential (GWP) Hydrofluorocarbon (HFC) refrigerants in new products and systems manufactured, imported, or installed after the compliance date for each subsector listed in the rule. The first restrictions begin January 1, 2025. For more information, see Hussmann’s one-page summary sheet on the rule here.

In addition to the federal HFC refrigerant regulations from the EPA, three states have also instituted or proposed rules to regulate HFCs and equipment that uses them—California, Washington, and New York.



New store installations with refrigerated systems beginning 1/1/2022 must not exceed 50 lb. of charge if they use a refrigerant with a GWP between 150 and 2,200.  Systems with greater than 50 lb. charge require refrigerants below 150 GWP.  Existing store compliance for CA requires a weighted average GWP of refrigerants used to be less than 1,400 GWP for the fleet by 2030 or a 55% reduction of overall Greenhouse Gas Potential (GHGP) compared to a 2019 baseline.


Like California, new refrigeration equipment with more than 50 lb. charge will be required to use a refrigerant below 150 GWP beginning 1/1/2025.  Washington has also created a Refrigerant Management Program that has requirements including leak detection, recordkeeping, and reporting.  Unlike California, Washington’s regulations do not include any requirements regarding the reduction of the GWP of refrigerants used in existing facilities.

New York

The state’s Department of Environmental Conservation has proposed HFC regulations under New York’s Climate Act law. The proposed rule covers several different aspects:

  • GWP Limits in New Equipment Starting in 2025
  • Refrigerant Sales Prohibitions Starting in 2025
  • Existing Facilities GWP Limits for Large Retailers starting in 2035
  • Refrigerant Management Including Leak Detection, Recordkeeping, and Reporting Requirements
