2023 Energy Efficiency Standards
From January 1, 2023, energy efficiency metrics for residential air conditioners and heat pumps will be expressed in terms of Seasonal Energy Efficiency Ratio (SEER2), Energy Efficiency Ratio (EER2), and Heating Seasonal Performance Factor (HSPF2).
The AIM Act & The HFC Phasedown
America’s HVACR manufacturers are committed to phasing down the use of high-global warming potential refrigerants. AHRI supports the American Innovation and Manufacturing (AIM) Act, legislation that promotes US technology, jobs and economic expansion.
The Safe Refrigerant Transition Task Force
AHRI’s Safe Refrigerant Transition Task Force addresses every step of the supply chain in the safe refrigerant transition to low-global warming potential refrigerants. The group comprises AHRI members and other stakeholders.

ASHRAE 90.1
ASHRAE Standard 90.1 provides the minimum requirements for energy-efficient design of most buildings, except low-rise residential buildings. It offers, in detail, the minimum energy-efficient requirements for design and construction of new buildings and their systems, new portions of buildings and their systems, and new systems and equipment in existing buildings, as well as criteria for determining compliance with these requirements. AHRI participates on the ASHRAE 90.1 standards committee and the mechanical subcommittee.

California Building Energy Efficiency Standards
California’s energy code is designed to reduce energy consumption in newly constructed and existing buildings. The standard applies to new construction of, and additions and alterations to, residential and nonresidential building. The California Energy Commission CEC) updates the Building Energy Efficiency Standards (Title 24, Parts 6 and 11) every three years by working with stakeholders in a public and transparent process.
