SEER Ratings Guide

As you shop for a new AC system, you may have come across the term “SEER rating.” Ever wonder what a SEER rating is and why it matters? Use this SEER rating guide to learn everything you ought to know about AC efficiency ratings and the new minimum SEER rating increase enacted by the federal government. 

What Is a SEER Rating? 

SEER stands for Seasonal Energy Efficiency Ratio, which is a measurement of how efficiently an air conditioner cools your home — or, to describe it another way, how effectively the equipment removes heat from the indoor air. The SEER rating is calculated by dividing the cooling output of an AC unit by the electricity it consumes across a whole season. Higher SEER ratings indicate a more energy-efficient air conditioning system. 

What Is SEER2? 

SEER2 is an updated SEER rating system that accounts for real-world usage patterns and regional climate data. This new metric took effect in January 2023 to give a more accurate representation of an AC system’s energy efficiency. 

Unlike the previous SEER rating system, which only considers an air conditioner’s energy efficiency in controlled conditions, the SEER2 metric offers homeowners a more authentic picture of how an AC unit will function once added in their home. As a result, you can expect SEER2 ratings to be a lower number than SEER ratings, despite the fact that they represent the same performance.  

What Is the Federal Minimum SEER2 Rating in 2023? 

The US Department of Energy (DOE) sets minimum efficiency requirements for HVAC systems. In 2023, the minimum SEER ratings for central air conditioners increased to 14 SEER (13.4 SEER2) in the northern U.S. and 15 SEER (14.3 SEER2) in the southern U.S. 

This is the first minimum efficiency rating increase since 2015, when the mandated minimum ratings were set to 13 SEER in the north and 14 SEER in the south. The DOE requires any new AC systems sold and installed in the U.S. to reach the new minimums. However, homeowners with lower efficiency air conditioners are not required to replace them. 

How Do SEER Ratings Affect AC Costs? 

Air conditioning systems with higher SEER ratings tend to cost more initially than units with lower SEER ratings. This is because ACs with higher SEER ratings integrate more advanced technology and materials to attain higher performance. However, while air conditioners with higher SEER ratings may involve a larger investment, they can save you money in the long run by lowering your energy bills. 

For example, let’s say you’re comparing two central air conditioners. System A has a SEER rating of 14 and costs $3,000, while System B has a SEER rating of 18 and costs $4,000. While System B is more expensive up-front, it can save you 22% on your cooling costs compared to System A. Depending on the environment and electricity costs in your town, this could perhaps equate to hundreds of dollars in savings over the years ahead, making System B a more cost-effective choice over time. 

Why Buy an AC with a Higher SEER Rating? 

You have more options than to just settle for the minimum SEER rating in your area, not when modern cooling systems are rated 26 SEER or higher. Consider the many benefits of purchasing such a high-end system: 

• Energy savings: As previously mentioned, ACs with higher SEER ratings are considerably more energy efficient. By consuming less energy to achieve the same cooling output, a high-end unit can save you significantly on your cooling expenses every summer for the life span of the system. 
• Environmental impact: Reduced energy consumption means fewer greenhouse gas emissions. Choosing an AC with a higher SEER rating reduces your home’s carbon footprint and contributes to a more sustainable future. 
• Enhanced comfort: Higher SEER-rated cooling systems are more sophisticated, with features such as two-stage compressors and multi-speed fan motors. Not only does this save energy and money, but it improves home comfort resulting in quieter, more effective operation.  
• Higher home value: New, high-efficiency ACs are more enticing to home buyers than outdated systems with lower ratings. If you decide to move, having a high SEER-rated AC system can increase the resale value and offer a compelling differentiator to potential buyers. This offers you yet another way to recoup your initial investment in a high-end air conditioner.
