What Is
a SEER2 Rating?
SEER2 stands for Seasonal Energy Efficiency Ratio 2, an updated measure of how efficiently an air conditioner cools your home. It’s the next generation of the original SEER rating, designed to reflect real-world conditions more accurately. Think of it like a car’s fuel efficiency rating: the higher the SEER2 rating, the more efficient the air conditioner, meaning it uses less energy to keep you comfortable.
How Does SEER2 Differ from SEER?
The original SEER rating was a good start, but it didn’t account for factors like ductwork efficiency or how fan speeds affect performance. SEER2 improves on this with a new testing method that includes these real-life elements. Imagine testing a car’s MPG on a smooth highway versus in stop-and-go city traffic—SEER2 gives you a truer picture of how your air conditioner will work in your home.
Why Does a Higher SEER2 Rating Matter?
A higher SEER2 rating benefits you in several ways:
- Lower Energy Bills: More efficiency means less electricity use. Upgrading to a high SEER2 unit could cut your cooling costs by up to 20% compared to older models.
- Eco-Friendly: Efficient air conditioners reduce energy consumption, shrinking your carbon footprint.
- Better Comfort: Units with high SEER2 ratings often come with advanced features like variable-speed compressors, providing steady cooling and better humidity control.


What SEER2 Rating Should You Look For?
In the U.S., new air conditioners must meet minimum SEER2 standards, which depend on your region (e.g., 13.4 in northern states and 14.3 in southern states). However, many modern units go beyond these minimums, with SEER2 ratings from 15 to 25 or higher. When choosing, check the SEER2 rating to find the right mix of upfront cost, energy savings, and cooling power for your home.
