SEER Savings Calculator

Check your unit's SEER label. Typical old units: 8-13 SEER
14 SEER = minimum, 16 = standard, 18+ = high-efficiency
1,500 = moderate climate, 2,000+ = hot climate

How Much Does SEER Upgrades Save?

Upgrading from SEER 10 to SEER 16 saves approximately 37% on cooling costs. For a 3-ton system running 1,500 hours/year at $0.15/kWh, that's about $180/year. The payback period depends on the cost difference between systems and your local electricity rate.

SEER (Seasonal Energy Efficiency Ratio) measures cooling output divided by electricity input over a typical cooling season. Higher SEER = lower operating costs. The US minimum is 14 SEER (2023+), with high-efficiency models reaching 28 SEER.

Frequently Asked Questions

How much does SEER 10 to 16 save?

Approximately 37% on cooling costs. For a 3-ton system at $0.15/kWh with 1,500 cooling hours, savings are about $180/year.

How is payback period calculated?

Payback = cost difference between SEER ratings ÷ annual savings. Typically SEER 16 costs $800-2,000 more than SEER 10. At $180/year savings, payback is 4-11 years.

What SEER should I buy?

Minimum 14 SEER (federal standard). 16 SEER is the best balance of cost and efficiency. 18+ SEER is worth it in hot climates or with tax credits.
