UL is an EPA-recognized certification body (CB) for the ENERGY STAR® program. Our energy efficiency test center is one of the largest HVAC/R performance testing facilities in North America, offering comprehensive capabilities for energy efficiency testing for a variety of HVAC/R product categories.

We offer energy testing and certification to international regulations and standards for:

  • Split and packaged small and large unitary equipment
  • Water-source air conditioning and heat pump equipment
  • Unit ventilators
  • Single package vertical air conditioners
  • Dehumidifiers
  • Unitary spot coolers
  • Chillers
  • DX coils
  • Water coils
  • Unit fan coils
  • Packaged terminal heat pumps
  • Household refrigerators
  • Commercial icemakers
  • Both self-contained and remote commercial refrigerated display merchandisers
  • Refrigerated vending machines

Real-time test data can be viewed live by our customers from anywhere in the world through our online data tracking software, facilitating faster troubleshooting.

We can perform safety certification testing on products at the same location where our energy efficiency testing is performed, improving operational efficiencies to help achieve time-to-market requirements. A UL representative can conduct or witness a test at a manufacturer’s facility if appropriate test equipment is available. If a manufacturer has a product installed in a commercial cooking establishment and does not have a UL Mark on the appliance, UL can perform a field evaluation at that location within a week of notification and provide a UL Field-Evaluated Product Mark for compliant equipment.
