SEER rating should be the No. 1 factor when choosing an air conditioner. Higher SEER rated AC units can save you $1,000s over the next 10-20 years in electricity bill savings.

To see exactly much you can save by choosing an air conditioner with a higher SEER (above the federally mandated minimum of 14 SEER), you can use the SEER savings calculator below. First, however, let’s look at one example:

Example: We have two 3 ton (36,000 BTU) central air conditioners. One has a 14 SEER rating and the other has a 20 SEER rating. Let’s take into account the average natural electricity cost of $0.1319 per kWh, and 1000h of AC use per season.

How much more efficient is a 20 SEER vs 14 SEER?

Solution: 14 SEER rated AC unit is powered (average seasonal wattage) by 36,000 BTU / 14 SEER = 2,570W; running it for 1,000 hours will spend 2,570 kWh. Total 14 SEER electricity cost = 2,570 kWh * $0.1319 per kWh = $338,72/year.

20 SEER rated AC unit is powered by 36,000 BTU / 20 SEER = 1,800W; running it for 1,000 hours will spend 1,800 kWh. Total 20 SEER electricity cost = 1,800 kWh * $0.1319 per kWh = $237,24/year.

In short, 20 SEER AC unit is 43% more energy-efficient than 14 SEER AC unit. Here are the savings:

  • Per 1 year: $101,48 electricity savings.
  • Per 10 years: $1.014,80 electricity savings.
  • Per 20 years: $2.029,6 electricity savings.

You save about 7% per 1 SEER on electricity costs.

We will explain how do you calculate air conditioner SEER further on. You can use this handy SEER savings calculator to calculate how much electricity will an AC unit with a specified SEER rating and tonnage cost:
