Note: Applicable standards depend on product design, refrigerant type, electrical configuration, and target markets. Testing and certification by an OSHA-recognized NRTL, such as Intertek, helps confirm compliance and supports approval by authorities having jurisdiction (AHJs).

Yes. The ETL Listed Mark is widely accepted for HVACR equipment across North America. As an OSHA-recognized Nationally Recognized Testing Laboratory (NRTL), Intertek certifies products to the same safety standards used throughout the industry, and the ETL Listed Mark serves as proof of compliance.

Authorities Having Jurisdiction (AHJs), inspectors, and code officials across the U.S. and Canada recognize and accept the ETL Listed Mark for HVACR products, making it a trusted pathway to demonstrating safety compliance and facilitating approvals for installation.

Yes. Both marks demonstrate compliance with the same nationally recognized safety standards and are equally accepted by regulators and code officials. The difference lies in the certification provider, not the level of safety or regulatory acceptance.

Any design, component, or material change may require a certification review. Depending on the change, additional evaluation or retesting may be required to maintain certification and ensure ongoing compliance.

New refrigerants introduce additional safety considerations. Testing and certification to updated standards such as UL 60335-2-40 or UL 60335-2-89 (dependent on product type) help manufacturers address flammability, system design, and regulatory compliance for low-GWP and A2L refrigerant systems.

Many HVACR products must demonstrate verified performance and efficiency to meet regulatory requirements or participate in incentive programs. This may include AHRI performance certification, regional energy regulations, or utility program requirements.

Independent third-party certification provides objective verification of compliance, builds trust with regulators and customers, and helps manufacturers reduce risk, avoid delays, and confidently bring products to market.

Yes. Different countries and regions have unique regulatory and certification requirements. Global market access programs, such as the CB Scheme and CE marking, help streamline approvals for international sales.
