Financially, it makes sense to replace an older 12 SEER unit with a new 16 SEER unit. *Right?* Well, that depends on the energy savings we will get with the new 16 SEER unit. To help you out with estimating the electricity savings, we have prepared a **12 SEER vs 16 SEER energy savings calculator**. On top of that, you will find calculated 1-year, 10-year, and 20-year savings in a neat

*further on.*

**chart**Namely, the 16 SEER AC unit is **33.3% more energy efficient** than a 12 SEER AC unit. That difference can produce $100s of savings in 1 year and $1000s of savings in the next 10 or 20 years, as evident from the chart.

*Example:* Let’s say you replace a **3.5-ton 12 SEER** unit with a **3.5-ton 16 SEER unit**. At $0.15/kWh electricity rates and 1000 running hours per year, the 12 SEER unit will use 3,500 kWh per year, costing $525/year. On the other hand, the more efficient 16 SEER unit will use 2,626 kWh/year, costing $393.75/year. The running cost difference is thus **$131.25/year**. The 16 SEER vs 12 SEER energy savings will reach $1,312.50 in 10 years, and whooping **$2,625.00 in 20 years**.

As we can see, the 12 SEER vs 16 SEER energy savings depend on the following:

**Size of the unit.**In the example, we had 3.5 ton AC unit. The higher the tonnage, the higher the 16 SEER vs 12 SEER energy savings.**Electricity prices.**In the example, we had $0.15/kWh electricity rates. At higher electricity rates, the 16 SEER vs 12 SEER energy savings increase.*Note:*We presume**1,000 hours per season running time**, in accordance with the DOE EnergyGuide calculation. That means you run the AC 8 hours per day for 125 days (a bit more than 4 months; usually May, June, July, and August).

Now, you probably don’t have a 3.5-ton AC unit, and the electricity cost in your area might not be $0.15/kWh.

To help you out calculating 16 SEER vs 12 SEER energy savings for any unit size (from 1 ton to 8 ton), and any electricity rates (from $0.05/kWh to more than $0.30/kWh), we have prepared a **simple calculator** you can freely use.

Just insert the AC tonnage and electricity prices, and the calculator will determine the 1-year, 10-year, and 20-year energy savings. Below the calculator, you will also find a ** chart with calculated 16 SEER vs 12 SEER 1-year, 10-year, and 20-year energy savings** for 1-8 tons units (presuming $0.15/kWh electricity rates):

## 12 SEER Vs 16 SEER Energy Savings Calculator

Here is an example of how to use this calculator:

Let’s say you are looking at two units; a 3-ton 12 SEER and a 3-ton 16 SEER unit. Your electricity rates are $0.18/kWh. How much will you save by picking 16 SEER unit over 12 SEER unit? Just slide the 1st tonnage slider to *‘3’* and the 2nd electricity price slider to *‘0.18’*, and you get the result:

By picking 16 SEER unit under these conditions, you will save **$135.00 per year**. That’s $1,350.00 savings in 10 years, and **$2,700 savings in 20 years**.

Here is the promised 12 SEER vs 16 SEER energy savings chart:

Unit Size (Tonnage): |
1-Year Savings ($): |
10-Year Savings ($): |
20-Year Savings ($): |

1 Ton |
$37.50 Savings Per Year | $375.00 Per 10 Years | $750.00 Per 20 Years |

1.5 Ton |
$56.25 Savings Per Year | $562.50 Per 10 Years | $1,125.00 Per 20 Years |

2 Ton |
$75.00 Savings Per Year | $750.00 Per 10 Years | $1,500.00 Per 20 Years |

2.5 Ton |
$93.75 Savings Per Year | $937.50 Per 10 Years | $1,875.00 Per 20 Years |

3 Ton |
$112.50 Savings Per Year | $1,125.00 Per 10 Years | $2,250.00 Per 20 Years |

3.5 Ton |
$131.25 Savings Per Year | $1,312.50 Per 10 Years | $2,625.00 Per 20 Years |

4 Ton |
$150.00 Savings Per Year | $1,500.00 Per 10 Years | $3,000.00 Per 20 Years |

5 Ton |
$187.50 Savings Per Year | $1,875.00 Per 10 Years | $3,750.00 Per 20 Years |

6 Ton |
$225.00 Savings Per Year | $2,250.00 Per 10 Years | $4,500.00 Per 20 Years |

7 Ton |
$262.50 Savings Per Year | $2,625.00 Per 10 Years | $5,250.00 Per 20 Years |

8 Ton |
$300.00 Savings Per Year | $3,000.00 Per 10 Years | $6,000.00 Per 20 Year |

As you can see, if we presume $0.15/kWh electricity prices and 1,000 running hours per year, the 16 SEER units will produce these energy savings (compared to 12 SEER units):

**$37.50 to $300.00**savings**per year**.**$375.00 to $3,000.00**savings in**10 years**.**$750.00 to $6,000.00**savings in**20 years**.

With these calculations, you can now make a more informed decision when deciding between 12 SEER and 16 SEER units. If you need a bit of advice, you can give us some numbers in the comments below, and we will help you out.
