The new EPA law, effective January 1, 2023, sets stricter energy efficiency standards for residential and commercial HVAC systems. This law introduces updated Seasonal Energy Efficiency Ratio (SEER2) and Energy Efficiency Ratio (EER2) ratings, which reflect more realistic performance metrics by incorporating new testing methods and conditions.
These changes aim to reduce energy consumption and greenhouse gas emissions, encouraging the adoption of more efficient heating and cooling systems. As a result, older models with lower efficiency ratings may be phased out, making way for newer, more eco-friendly equipment. For homeowners, this means investing in more efficient HVAC systems can lead to lower energy bills and improved comfort.
