So, What Exactly Is SEER2?
SEER stands for Seasonal Energy Efficiency Ratio, and it tells you how efficiently an air conditioner converts electricity into cooling power. The higher the number, the better the efficiency.
But as of January 1, 2023, the Department of Energy rolled out SEER2, an updated standard designed to better reflect real-world conditions—especially external static pressure caused by ductwork and filters.

SEER vs. SEER2: What’s the Difference?
Here’s a quick comparison:
| Metric | SEER (Old) | SEER2 (New) |
|---|---|---|
| Testing Conditions | Ideal Lab Settings | Real-World External Pressure |
| Efficiency Labeling | Slightly Inflated | More Accurate |
| Regional Requirements | North: 13–14 SEER | North: 13.4 SEER2 |
| Impact on Cost | May Seem Cheaper | Reflects True Performance |
While SEER2 numbers may look lower than SEER at first glance, they actually reflect tougher testing standards—meaning your system’s real performance is easier to understand.
Why SEER2 Ratings Matter for Your Budget
Let’s talk numbers.
Let’s say you live in Texas and run your AC heavily during the summer. A system with a SEER2 rating of 14.5 will use less energy than a 13.4 SEER2 model—meaning lower monthly bills.
According to the Department of Energy, switching to a high-efficiency unit can cut cooling costs by 20–40% depending on your home’s layout and your old system's rating.

Understanding Minimum SEER2 Requirements
Here’s what’s required in your region:
| Region | Minimum SEER2 Rating (AC) |
|---|---|
| North | 13.4 |
| South | 14.3 |
| Southwest | 14.3 |
If you’re in the South or Southwest, systems like this are your new baseline:

How to Choose the Right SEER2 Rating
You don’t always need the highest SEER2 system available. Here’s how to shop smart:
✅ Choose 13.4–14.5 SEER2 if:
-
You live in a mild climate.
-
You’re on a tight budget.
-
You plan to move in a few years.
✅ Choose 15–17+ SEER2 if:
-
You live in a hot, humid state.
-
You want the best energy savings long-term.
-
You’re eligible for utility rebates (many require 15 SEER2 or higher).
Don’t Forget: Efficiency Depends on the Whole System
It’s not just about the condenser’s SEER2 label. Your air handler, ductwork, and thermostat** all contribute to how efficiently your system runs.
💡 Tip from Samantha: Make sure your air handler is SEER2-matched, like the Goodman AMST series, which is designed to maximize energy savings with modern R-32 systems.

Final Thoughts from Samantha
SEER2 is more than just a number—it’s your ticket to lower monthly bills and smarter energy use. Whether you’re upgrading an old unit or building a high-efficiency home, choosing the right SEER2 rating means real savings and greater comfort.
Smart shopping isn’t just about buying new—it’s about buying better.
