What's a SEER Rating—And What Does It Mean?

If you’re like many homeowners, you probably don’t give much thought to your air conditioner until it stops working. But when you’re unexpectedly left with no choice but to install a new a/c unit, the SEER rating is an important factor you’ll need to consider when making the best choice for your home.

What Is a SEER Rating?

SEER stands for Seasonal Energy Efficiency Ratio. Air conditioner units with high SEER ratings use less electricity to get your home to a comfortable temperature, reducing your energy or gas bill.

Mathematically speaking, a unit’s SEER rating is calculated by dividing the annual cooling output (measured in BTUs) by the total electric energy input (measured in kilowatt-hours)—in other words, dividing the amount of cool air the a/c generates by the number of kilowatts it takes to generate it.

What to Consider When Choosing a SEER Rating

The relationship between SEER ratings and efficiency doesn’t necessarily mean that you choose an a/c unit with the highest SEER rating you can find. There are other factors that may determine what SEER rating is best-suited for your home and overall HVAC system.

First, it’s important to note that a SEER rating signifies the maximum efficiency a particular unit can reach. It doesn’t mean that the unit will operate at that efficiency all of the time or even some of the time. For example, a top-of-the-line 20 SEER unit that’s far too large for the house it’s cooling is unlikely to ever perform at a higher rating than a more appropriately-sized unit, even one with a lower SEER rating. Knowing how the geography and climate of your area impact efficiency can ensure you don’t overpay for a higher SEER rating than you need.

You’ll also want to consider variables like your budget, your home size, how often your a/c is running, and how much time you spend at home. All of these factors can affect the necessary efficiency of the unit you choose.
