What Is The Difference Between SEER and SEER2?

SEER and SEER2 are both measures of energy efficiency for air conditioners. SEER stands for Seasonal Energy Efficiency Ratio, and SEER2 is an updated version of SEER that includes additional factors to account for variable speed compressors and other advancements in air conditioning technology.

The SEER rating is determined by dividing the cooling output of an air conditioner over a typical cooling season by the energy it consumes in watt-hours. A higher SEER rating indicates a more energy-efficient air conditioner. The minimum SEER rating required by the Department of Energy (DOE) for air conditioners sold in the United States is 14. However, some states have set their own higher standards, and many manufacturers now produce air conditioners with SEER ratings of 16 or higher.

SEER2 is an extension of SEER that is used to evaluate air conditioners with variable speed compressors. Variable speed compressors can adjust their speed to match the cooling needs of a home, which can lead to significant energy savings. SEER2 also includes factors to account for other advancements in air conditioning technology, such as advanced control systems and improved evaporator coils.

When comparing SEER and SEER2 ratings, it’s important to note that SEER2 is not simply a higher number than SEER. The rating systems are different and the calculation of SEER2 is more complex and take into account more factors than SEER. The point is to give an more accurate and precise evaluation of energy efficiency.

It’s important to note that a high SEER or SEER2 rating alone is not a guarantee of energy savings or cost savings. Other factors, such as the size of the air conditioner, the level of insulation in your home, and how you use the air conditioner, can also have a significant impact on energy consumption and costs.

When purchasing a new air conditioner, homeowners should look for models with high SEER or SEER2 ratings, but also consider the size and cost of the unit, as well as any rebates or tax credits that may be available for energy-efficient air conditioners.

In summary, both SEER and SEER2 are measures of energy efficiency for air conditioners, with SEER2 including more factors such as variable speed compressors and other advancements in technology. Both ratings can give a good indication of an AC’s energy efficiency, but other factors such as size, cost and rebates/tax credit should also be considered when purchasing a new air conditioner.
