The New Standard in AC Efficiency
If you're shopping for a new air conditioner, you've probably seen SEER2 ratings on equipment. SEER2. Seasonal Energy Efficiency Ratio 2, is the updated standard that replaced the original SEER rating system in January 2023.
The key difference: SEER2 uses more realistic testing conditions with higher external static pressure, which better reflects how your system actually performs in your home. This means SEER2 numbers are slightly lower than the old SEER numbers, even though the equipment hasn't changed.
How to Read SEER2 Ratings
Here's a general guide to SEER2 efficiency levels:
- 14-15 SEER2. Entry level, meets minimum code requirements. Good for budget-conscious buyers.
- 15-17 SEER2. Mid-range efficiency. Good balance of upfront cost and energy savings.
- 17-20 SEER2. High efficiency. Significant energy savings, especially in Greenville's long cooling season.
- 20+ SEER2. Premium efficiency. Maximum energy savings with variable-speed technology for the ultimate comfort.
What Makes Sense for Greenville?
In Greenville's climate, where we run AC for 5-6 months per year, a higher SEER2 rating delivers more value than in milder climates. The energy savings compound over the system's 15-20 year lifespan. We typically recommend 16+ SEER2 for the best balance of cost and efficiency.
