U.S. HVAC Updates
Your interactive guide to efficiency standard regulations and refrigerant updates.
In 2022, new federal and regional efficiency regulations will go into effect in all U.S. states and territories. These regulations include the transition to a new test standard M1. This will result in the change from SEER to SEER2, HSPF to HSPF2 and EER to EER2 as the standard measurements of efficiency. Please click a state on the map to see applicable regulations and implementation dates. You will also find announced A2L refrigerant transition dates.
Dates and information as of 12/17/2020.
