Understanding SEER2 Ratings and Energy Efficiency in Air Conditioners
Introduction
Energy efficiency is one of the most critical factors when choosing an air conditioner. The Seasonal Energy Efficiency Ratio 2 (SEER2) is a key metric that determines how efficiently an air conditioner operates under real-world conditions. The Goodman GSXN402410 boasts a 14.3 SEER2 rating, making it an efficient and cost-effective option. This article will explain what SEER2 means, how it affects energy consumption, and how to choose the right SEER2 rating for your needs.

What Is SEER2?
SEER2 is the new efficiency standard for air conditioners, introduced by the Department of Energy (DOE) to replace the original SEER metric. It provides a more accurate measurement of an AC system’s efficiency by factoring in real-world external static pressures that affect performance.
How SEER2 Is Calculated
- SEER2 is measured by dividing the cooling output (BTUs) over a cooling season by the total electric energy input (watt-hours).
- The formula:
SEER2 = Total Cooling Output (BTU) / Total Energy Consumed (kWh) - Higher SEER2 values indicate greater energy efficiency.

SEER2 vs. SEER: What’s the Difference?
| Feature | SEER | SEER2 |
|---|---|---|
| Testing Standard | Laboratory conditions | Real-world external pressures |
| Introduced | 1979 | 2023 |
| More Accurate? | No | Yes |
| Higher Efficiency? | Varies | Provides a better efficiency benchmark |
The key takeaway: SEER2 ratings provide a more realistic measure of an air conditioner's efficiency under actual working conditions.

Why SEER2 Ratings Matter
1. Energy Savings
A higher SEER2 rating means less electricity consumption. Compared to older units with low SEER ratings (10-12 SEER), a 14.3 SEER2 unit like the Goodman GSXN402410 can provide significant energy savings.
For example:
- A 10 SEER unit consumes 40% more energy than a 14.3 SEER2 unit.
- A 16 SEER2 unit saves 10-15% more energy than a 14.3 SEER2 model.
2. Environmental Benefits
- Reduces carbon footprint by lowering energy consumption.
- Promotes eco-friendly cooling with refrigerants like R-410A.
- Helps comply with EPA energy standards.
For a breakdown of environmental impacts, read EPA’s guide on energy-efficient appliances.
3. Comfort and Performance
- High SEER2 air conditioners provide more consistent temperatures.
- Reduces humidity more effectively.
- Operates quieter due to more advanced compressors.
Choosing the Right SEER2 Rating for Your Home
Selecting the right SEER2 rating depends on:
1. Climate Zone
- Hot climates (Texas, Florida, Arizona): 16 SEER2+ recommended.
- Moderate climates (North Carolina, Tennessee): 14-16 SEER2 sufficient.
- Cooler climates (New York, Washington): 14 SEER2 is enough.
See SEER recommendations per state at Energy Star’s SEER guide.
2. Home Size and Insulation
- Large homes with poor insulation benefit from higher SEER2 units.
- Small to medium homes with good insulation can operate efficiently with 14-16 SEER2 units.
3. Budget Considerations
| SEER2 Rating | Initial Cost | Annual Energy Savings |
|---|---|---|
| 14.3 (Goodman GSXN402410) | $$ | Moderate |
| 16 SEER2 | $$$ | Higher savings |
| 18 SEER2 | $$$$ | Maximum efficiency |
