The UL Mark signals that products have been tested to applicable safety standards by a global safety science leader, helping differentiate your offering and build customer confidence.
Beyond certification, UL Solutions supports product development with advisory and benchmarking, and collaboration with authorities and standards bodies such as the Air-Conditioning, Heating, and Refrigeration Institute (AHRI); the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), and Eurovent to help move the HVACR industry forward.
UL Solutions offers Marketing Claim Verification and performance services that provide independent, science‑based proof for advertised claims, helping products stand out in competitive categories. See performance and claim verification options on our HVACR performance page and segment pages.
Third‑party testing helps demonstrate that products meet applicable safety and performance standards, supporting regulatory compliance and customer confidence in the UL Mark. This helps brands differentiate in the HVAC market and adapt to regulatory change.
Start with UL Product iQ®, which lets you verify certifications by keyword, category or identifiers like CCN or file number. If you already have an exact certificate number, use Search Certificates for a direct lookup.
Core services include but are not limited to energy efficiency, sound, load‑based testing (LBT), CVP, IVEC/IVHE and support for ESPR reporting, delivered through global ISO 17025‑accredited labs.
The UL and IEC standards 60335-2-40 and IEC 60335-2-40 offer HVACR manufacturers a path to certification for coolant distribution units (CDUs) using refrigerant liquid. Distributing coolants directly to the heat sources — either through the rack or directly to the component CDUs — helps manage thermal loads in an efficient and sustainable way for data center cooling. Visit Testing and Certification for Low GWP Refrigerants and Coolant Distribution Units (CDUs) to learn more.
