How much does a higher-efficiency AC save in Los Angeles? With a moderate cooling season (about 1,000 cooling hours a year) and roughly $0.29/kWh electricity, upgrading a 3-ton AC from 10 SEER to 16 SEER2 in Los Angeles saves about $446/year — $6,697 over 15 years, a 41% energy cut. The calculator below is pre-set to Los Angeles.
Understanding the New DOE SEER2 Efficiency Mandates
As of 2023, the Department of Energy transitioned from the SEER to the SEER2 testing standard to better reflect real-world operating conditions, particularly static pressure in ductwork. Upgrading to a higher SEER2 system directly reduces your monthly energy bills. In the Northern US, the minimum standard is now 13.4 SEER2, while the South and Southwest require a minimum of 14.3 SEER2. The calculator below helps you determine exactly how much money you will save annually by investing in a high-efficiency unit compared to your current system’s rating.
🌡️ How Much Will a Higher SEER2 Save You?
See how much a higher-efficiency AC or heat pump will save you. Compare your old SEER unit to a new SEER2 system and get the annual savings, 15-year total, payback period and energy cut — for your climate and electricity rate.
🔻1. Your Current System (SEER)
Range: 8 – 18 SEER. AC units from before ~2006 are often 8–10 SEER; 2006–2022 units are 13–16 SEER. Check the yellow EnergyGuide label or nameplate.
🔺2. New System (SEER2)
Range: 13.4 – 24 SEER2. Minimum new units are 13.4 (North) / 14.3 (South) SEER2; high-efficiency 16–18; premium variable-speed 19–24.
📏3. System Size
Range: 1.5 – 5 Tons. A typical home is 2–3.5 tons. Not sure? Use our AC Tonnage Calculator.
🌍4. Climate
Hotter climates run the AC far more hours a year, so the savings from higher efficiency are much larger.
⚡5. Electricity Rate
US average is about $0.16/kWh; California, the Northeast & Hawaii run higher. Check your utility bill for the exact figure.

SEER2 Upgrade Savings in Los Angeles by Efficiency Jump
Annual cooling savings for a 3-ton system at Los Angeles’s climate and rate. Bigger efficiency jumps save more:
| Upgrade | Annual Savings | 15-Year Savings |
|---|---|---|
| 10 SEER → 14 SEER2 | $353 | $5,298 |
| 10 SEER → 16 SEER2 | $446 | $6,697 |
| 10 SEER → 20 SEER2 | $577 | $8,654 |
Why SEER2 Savings Differ in Los Angeles
Two things drive AC upgrade savings: how many hours you cool, and what you pay per kWh. Los Angeles has a moderate cooling season (~1,000 hours) and about $0.29/kWh, so a high-efficiency upgrade pays off strongly here.
