<\/a><\/figure>\n\n\n\nWhat Is SEER2?<\/strong><\/h2>\n\n\n\nSEER stands for Seasonal Energy Efficiency Ratio. It measures how efficiently an air conditioner or heat pump can cool your home over an entire cooling season. The higher the SEER rating, the more cooling you get for every dollar you spend on electricity. SEER2 is the updated version of SEER that came into effect in 2023. It uses new testing procedures that better reflect real-world conditions, including higher static pressure to simulate the impact of your home\u2019s ductwork on system performance.<\/p>\n\n\n\n
In short, SEER2 gives you a more accurate picture of how efficient an AC unit will be once installed in your home.<\/p>\n\n\n\n
How SEER2 Differs from SEER<\/strong><\/h2>\n\n\n\nThe biggest difference between SEER and SEER2 is the testing method. SEER2 testing standards are tougher, so a unit\u2019s SEER2 number will typically be slightly lower than its old SEER number for the same equipment. For example, an AC that was rated at SEER 16 under the old system might now be rated around SEER2 15.<\/p>\n\n\n\n
This change doesn\u2019t mean your system is less efficient\u2014it just means you\u2019re getting a more realistic idea of how it will perform when battling our Louisiana heat and humidity.<\/p>\n\n\n\n
Minimum SEER2 Requirements<\/strong><\/h2>\n\n\n\nThe U.S. Department of Energy sets minimum efficiency standards for air conditioners, which vary by region to account for different climate demands. Here in the South\u2014including Louisiana\u2014the minimum SEER2 requirement for new central AC units is currently 14.3 SEER2 (which equates to about 15 SEER under the old rating).<\/p>\n\n\n\n
In the Northern U.S., the minimum is slightly lower at 13.4 SEER2, since those regions don\u2019t face the same long cooling seasons. Because our summers are hot and sticky, meeting only the minimum standard may not be the smartest financial choice for Louisiana homeowners.<\/p>\n\n\n\n
Why a Higher SEER2 Rating Makes a Difference<\/strong><\/h2>\n\n\n\nChoosing an air conditioner that exceeds the minimum SEER2 rating can pay off in a big way in our climate. A higher SEER2 unit uses less energy to keep your home comfortable, which means lower monthly utility bills. Over the life of your system, those savings can add up to thousands of dollars\u2014more than enough to offset the higher upfront cost of a more efficient unit.<\/p>\n\n\n\n
Plus, higher-efficiency systems often include advanced features like variable-speed compressors and fans, which provide more consistent comfort and quieter operation.<\/p>\n\n\n\n
