What is SEER and Why It Matters?
The Seasonal Energy Efficiency Ratio (SEER) indicates how much electricity an air conditioner consumes over the cooling season.
The higher the SEER, the more energy-efficient the system is.
Example:
- 13 SEER = basic efficiency
- 14 SEER = standard in many areas
- 16 SEER = high-efficiency
- 20+ SEER = ultra-high (usually inverter ACs)

16 SEER is about 23% more efficient than 13 SEER
13 SEER vs 16 SEER Annual Cost Comparison
| AC Size | Hours/Year | Electricity Rate | 13 SEER Annual Cost | 16 SEER Annual Cost | Annual Savings |
|---|---|---|---|---|---|
| 2 Ton | 1,200 | $0.13/kWh | ~$240 | ~$195 | ~$45/year |
| 3 Ton | 1,500 | $0.15/kWh | ~$415 | ~$340 | ~$75/year |

| AC Size | Hours/Year | Electricity Rate | 14 SEER Annual Cost | 16 SEER Annual Cost | Annual Savings |
|---|---|---|---|---|---|
| 2 Ton | 1,200 | $0.13/kWh | ~$220 | ~$195 | ~$25/year |
| 3 Ton | 1,500 | $0.15/kWh | ~$385 | ~$340 | ~$45/year |
When Should I Get a More Efficient System with Higher SEER?
You should upgrade to a 16 SEER if:
- You live in hot states (e.g., Arizona, Texas, etc.).
- Your average more than 1,200 hours/year using AC.
- You plan to stay in the home for 5 or more years.
You probably should not upgrade to a 16 SEER if:
- Your current AC system is fairly new.
- You live in a moderate climate and do not use AC much.
- The upfront cost of the 16 SEER is significantly higher than the 13 SEER.

FAQ: Frequently Asked Questions:
Q: How much more efficient is a 16 SEER when compared to a 13 SEER?
A: A 16 SEER is about 23% more efficient, possibly saving you $40-$100/year depending on use.
Q: Is a 16 SEER worth the money after the upfront cost?
A: Generally, yes, if you use your AC often enough and plan to stay in your house for 5 or more years.
Q: What is the legal SEER?
A: As of January 2023, a majority of states in the U.S. have a minimum 14 SEER, and southern states have even higher minimums.
