What is one of the requirements for HVAC equipment manufactured after 1993?

Must be capable of recovering 70% with a compressor

Must be certified or listed (UL, E.T.L.)

The requirement that HVAC equipment manufactured after 1993 must be certified or listed by an organization such as UL (Underwriters Laboratories) or ETL (Intertek) is significant for ensuring safety, performance, and reliability. Certification by these organizations involves rigorous testing and evaluation of the equipment to comply with specific safety standards and operational guidelines. This certification confirms that the HVAC equipment meets nationally recognized safety and performance standards before it can be sold and used.

This requirement is especially important as it provides assurance to consumers, contractors, and regulators that the equipment has been evaluated and adheres to quality standards, thereby reducing risks and enhancing safety in installation and operation. This oversight is crucial to avoid faulty or unsafe HVAC systems that could lead to failures, accidents, or inefficiencies.
