You are viewing the Sandersville, GA location.
If you’re considering a new AC installation in Sandersville, GA for your home or business, you’ve likely come across terms like SEER, SEER2, and EER2. These efficiency ratings can seem confusing at first, but understanding what they mean is key to making an informed decision—and ensuring you get the best performance and value from your investment.
Here’s what you need to know about the latest efficiency standards and how they affect your next AC installation.
What Is SEER?
SEER stands for Seasonal Energy Efficiency Ratio. It’s the industry-standard metric used for decades to measure the cooling efficiency of air conditioners and heat pumps. The higher the SEER rating, the more efficient the system is at cooling your home while consuming less energy.
Under the old system, a SEER rating of 14 or higher was considered efficient for Southern regions like Georgia. However, the way we measure that efficiency has recently changed.
Introducing SEER2 and EER2
As of January 1, 2023, the Department of Energy (DOE) updated its testing procedures for HVAC systems to better reflect real-world operating conditions. This update led to the introduction of SEER2 and EER2 (Energy Efficiency Ratio 2), which replace the older SEER and EER metrics.
What’s Different?
SEER2 and EER2 ratings use revised testing methods that factor in external static pressure—basically, the resistance that air encounters as it moves through your ductwork. These tests are more rigorous and reflect the kind of performance you can actually expect in a real home.
Because of the stricter testing, SEER2 numbers are lower than their SEER counterparts, even though the equipment itself may be just as efficient. For example:
A unit that was rated 14 SEER under the old system might now be rated around 13.4 SEER2.
This change doesn’t mean today’s systems are less efficient—it just means the rating system is more accurate.
Why Does SEER2 Matter for Homeowners in Sandersville?
In Georgia’s hot and humid climate, AC efficiency directly impacts your comfort and your energy bills. The new SEER2 standards make it easier for you to compare systems based on how they’ll actually perform in real-world conditions, not just in a lab.
In the Southeast region, the minimum SEER2 requirement for new central AC systems is now 14.3. That means any new system installed in Sandersville must meet this updated threshold.
By upgrading to a system with a high SEER2 rating, you can expect:
- Lower monthly energy bills
- More consistent indoor comfort
- Reduced environmental impact
- Longer system lifespan with less strain on components
EER2: Another Efficiency Factor
While SEER2 measures seasonal efficiency over time, EER2 focuses on steady-state performance at a specific outdoor temperature—usually 95°F. This is especially helpful in evaluating how your system will perform during extreme heat.
When comparing AC systems, looking at both SEER2 and EER2 can give you a fuller picture of energy performance under varying conditions.
