Air Conditioner Efficiency Updates in 2023 

Beginning January 1, 2023, new efficiency standards for A/C units will take effect. The new regulations will focus on the energy efficiency of air conditioning systems. The new rating for the South will be 15 SEER. 

What is a SEER rating? 

The seasonal energy efficiency ratio (SEER) measures the energy efficiency of an A/C unit. It is a maximum efficiency rating, so the higher the SEER number…

the less energy is needed which makes the unit more energy efficient. State by State the standards vary due to the different climates. The minimum required SEER rating is based off where in the U.S. you may live and how large the unit is which is based off the size of a home.


New SEER2 protocols will affect heat pumps, single packaged units, evaporated coils, air conditioner condensing units, and gas furnaces manufactured after January 1, 2023. An increased performance standard will be required in the South of 15 SEER or 14.3 SEER2. These new high-efficiency units will reduce the impact on the environment.  

Testing procedures have changed 

The old testing procedures were not accurate for the real-world conditions surrounding A/C units. Many factors can affect the energy consumption and static pressures in a unit due to poorly designed ductwork.  

What does this mean for homeowners? 

Homeowners will not be required to replace their existing air conditioner unit if it does not meet the new standards. It will only be required if the old one fails and needs to be replaced. The new requirements will cost more upfront but will save money in the long run. The higher the SEER rating number, the more money it can save homeowners on their electric bill year after year.  

All newly manufactured equipment must meet the updated SEER2 standards by the beginning of 2023.

Will newer units last longer? 

Air conditioner units with a higher SEER rating typically last longer than ones with a lower rating. This means that even though the upfront cost is more, you will get longer longevity out of it and not have to replace it as soon as ones with a lower efficiency rating.  

New construction requirements 

When buying or building new construction homes, builders must comply with the standards in place. Since these new regulations are beginning on January 1, 2023, all builders are already aware of these changes and complying with the new requirements. This means that as a buyer of a new home, you will not have to worry about the new SEER requirements or potentially having to replace an old unit. You can be certain that your new home will come with the most energy efficient unit.
