## How much will I save on my utility bill if I get a new higher SEER air conditioner?

Thursday, July 26, 2018

Figuring out the percentage reduction of your electric bill for a new air conditioner is fairly simple. Subtract the SEER of your current unit from the SEER of a system you are considering buying, and then divide that number by the SEER of the new system. If you are going from 12 to a 16 SEER, the calculation would be 16 - 12 = 4, and 4 ÷ 16 = 0.25, so the savings would 25% of the portion of the bill for home cooling. If you are not sure of the SEER of your current HVAC system, go to our blog post “How can I find out the SEER of my air conditioner?”

Calculating your actual dollar savings is more complicated. If you live in Florida, like us, you use the a/c a lot more than someone in Ohio and, of course, the cost per kilowatt hour for electricity in your area also impacts your savings. We recommend using one of the online calculators, and Lennox has an excellent one at:

Here’s example below of the results for a 12 to 16 SEER upgrade in Florida. As you can see, the percentage savings matches our easy calculation method, but it also shows dollar savings for 5, 10, and 15 year periods.
