Why Efficiency Ratings Matter More Than Ever in 2025
Energy costs aren’t going down anytime soon. In fact, according to Energy.gov, HVAC accounts for over 40% of home energy use. That means the efficiency of your system isn’t just about being eco-friendly—it’s about saving hundreds or even thousands of dollars over the life of the unit.
Plus, in 2023 the industry introduced SEER2 testing, which uses stricter standards to reflect real-world conditions. For us homeowners, that means ratings are now more accurate, and the best systems really stand out.
🏷️ 1. Breaking Down the Ratings
🔵 SEER2 – Seasonal Energy Efficiency Ratio 2
-
What It Means: Measures cooling efficiency over a typical season.
-
New Standard (since Jan 2023): More rigorous than old SEER.
-
Why It Matters: Higher SEER2 = lower summer cooling costs.
💡 Example: An Amana system with 21 SEER2 may use 40% less energy than a 14 SEER2 baseline system.
🟠 EER – Energy Efficiency Ratio
-
What It Means: Efficiency at peak demand (95°F outdoor temperature).
-
Why It Matters: Crucial for hot, sunny climates where AC runs hardest.
-
Pro Tip from Savvy: If you live in the South, don’t just look at SEER2—make sure your Amana unit has a strong EER.
🟢 HSPF2 – Heating Seasonal Performance Factor 2
-
What It Means: Heating efficiency of heat pumps over the season.
-
Why It Matters: Higher HSPF2 = lower winter electricity bills.
-
Pro Tip: Look for HSPF2 ≥ 9 if you live in a colder state.

🌀 2. How Amana HVAC Systems Perform
Amana is known for combining reliability with efficiency. Here are some standout models in 2025:
❄️ Amana Central Air Conditioners
-
ASXC16: Up to 16 SEER2, 12.5 EER, ENERGY STAR certified.
-
AVXC20: Up to 21 SEER2, 13 EER, inverter-driven for top efficiency.
🌡️ Amana Heat Pumps
-
ASZC16: 16 SEER2 / 12 EER / 8.5 HSPF2.
-
AVZC20: 21 SEER2 / 13 EER / 10.5 HSPF2 (qualifies for maximum rebates).
🔥 Amana Furnaces (for combo setups)
-
AMEC97: 97% AFUE, pairing perfectly with an AC unit for northern climates.
💲 3. How Efficiency Ratings Impact Your Bills
Here’s what I found while comparing:
-
Each SEER2 point = ~5–7% energy savings.
-
In hot climates, a 21 SEER2 AC vs. a 14 SEER2 baseline could save $400–$600 per year.
-
High HSPF2 (≥10) heat pumps can cut winter heating costs by up to 30% compared to standard models.
👉 Consumer Reports confirms that upgrading to a high-efficiency system pays for itself within 5–7 years in most regions.
🌍 4. Climate Considerations
Efficiency ratings are only half the story. Where you live changes everything.
☀️ Hot Southern States
-
Prioritize SEER2 and EER.
-
Amana’s AVXC20 shines in Florida, Texas, and Arizona.
❄️ Northern States
-
Look at HSPF2 for heat pumps.
-
If winters are below 25°F, consider pairing an AC with Amana’s AMEC97 furnace.
🌦️ Mixed Climates
-
Amana’s dual-fuel systems automatically switch between a heat pump and a furnace for maximum efficiency.

📉 7. Mistakes Homeowners Make (and How Savvy Avoids Them)
-
❌ Only looking at SEER2 → ignoring EER leads to high bills in heat waves.
-
❌ Oversizing equipment → more cycling, less comfort, wasted money.
-
❌ Neglecting ductwork → up to 30% efficiency loss
-
❌ Skipping professional installation → voids warranty & rebates.
💡 8. Savvy’s Tips for Choosing the Right Amana
-
✅ Compare SEER2 & EER if you live in a hot state.
-
✅ Look for HSPF2 ≥9 if winters get chilly.
-
✅ Always check Energy Star Rebate Finder before buying.
-
✅ Demand a Manual J calculation from your contractor.
-
✅ Register your Amana within 60 days to secure the Lifetime Limited Warranty.
🧮 9. Real-World Example
