Let’s help you calculate the 10 SEER vs 16 SEER energy savings. In these cases, you usually have 20+ year old 10 SEER unit and are wondering if it *makes sense* to replace it with a 16 SEER unit. To help you out, we have created a 10 **SEER vs 16 SEER energy savings calculator** you can freely use. On top of that, we have calculated

**1-year**,

**10-year**, and

**20-year**savings and gathered the results in the

**further on.**

*chart*Alright, we all know that a 16 SEER unit is more energy efficient than a 10 SEER unit. The electricity usage difference is substantial; 16 SEER unit is **60.0% more energy efficient** than 10 SEER unit. For the biggest 8-ton units, that can literally mean over $10,000 in energy savings during a 20-year AC lifespan *(specified in the chart below)*.

Let’s look at one quick example (it will help you use the calculator and chart below). Suppose we have a** 3-ton** 10 SEER AC unit and are looking to replace it with a new 3-ton 16 SEER unit. What are the energy savings we can expect here?

Using this formula, we can calculate the average running wattage for both units:

**AC Running Wattage = Tonnage Ã— 12,000 / SEER Rating**

Here are the results for a 3-ton unit at a $0.15/kWh electricity rate and 1,000 running hours per year:

**10 SEER 3-ton**unit runs on 3,600 watts, and it thus uses 3.6 kWh of electricity per hour. That means our expected yearly AC bill is**$540**.**16 SEER 3-ton**unit runs on 2,250 watts, and it thus uses 2.25 kWh of electricity per hour. That means our expected yearly AC bill is**$337,50**.

In this situation, if you replace a 10 SEER unit with a 16 SEER unit, you are looking at **$202,50 energy savings per year**. That’s $2,025 savings in 10-years and whooping **$4,050 savings in the next 20 years**.

Now, you might be looking to replace 2-ton, 2.5-ton, 4-ton, 5-ton unit, and so on. The electricity rates in your are might not be $0.15/kWh; they can be as low as $0.08/kWh or as high as $0.30/kWh.

To help you out with the energy savings calculation, we have prepared the **10 SEER vs 16 SEER calculator** you can freely use. Use the 1st slider to specify the AC tonnage, and the 2nd slider to specify the electricity rates. The calculator will give you 1-year, 10-year, and 20-year energy savings.

Below the calculator, you will also find a **10 SEER vs 16 SEER chart** for 1-8 ton AC units ($0.15/kWh) and the corresponding 1-year, 10-year, and 20-year energy savings:

## 10 SEER Vs 16 SEER Energy Savings Calculator

Let’s take a big 5 ton AC unit to illustrate how this calculator works. The electricity rates in your area are $0.12/kWh. You slide the 1st slider to *‘5’* and the 2nd one to *‘0.12’*, and you get this result:

By choosing 16 SEER over 10 SEER 5-ton unit, you are looking at **$270.00 savings per year**. That’s $2,700 savings in 10 years, and very high **$5,400 savings in 20 years**.

You can see that upgrading from 10 SEER to 16 SEER unit is a financially *very* smart choice.

Here are the calculated 10 SEER vs 16 SEER 1-year, 10-year, and 20-year energy savings at $0.15/kWh and 1,000 running hours/year for 1-8 ton units:

We can see that replacing 10 SEER unit with a 16 SEER unit will produce:

**$67.50 to $540.00**savings.**per year****$675 to $5,400**savings in.**10 years****$1,350 to $10,800**savings in. That’s quite incredible savings.*20 years*

From these simple calculations, we can see that upgrading 10 SEER to 16 SEER unit can save us $1,000 in the next 10 to 20 years. If you are still in a dilemma, you can give us some figures in the comments below, and we will help you out with the calculations. Thank you.
