What are EER and SEER?

What are EER and SEER?The need for cooling in the Texas Panhandle is so high it’s important to understand how efficient your home’s air conditioner is at handling the task. Two ratings — the SEER rating and the EER rating — indicate how much energy a central system uses to cool, but they’re measured under different temperatures to learn system performance under variable weather conditions.

Engineers measure the amount of electricity the system uses. Those that use less energy receive higher EER and SEER ratings.

The current minimum rating for the SEER stands at 14 in Texas. Although the U.S. Department of Energy (DOE) requires the manufacturer to disclose the SEER for central systems, it does not require EER disclosure for consumers. However, central systems that receive the Energy Star designation must disclose both the EER and SEER rating.

Summer temperatures in the Panhandle often climb into the 90s, so paying attention to the EER makes sense. Having a central A/C or heat pump with a high EER will help you save energy dollars during the hottest parts of the day, since the higher EER indicates better performance at more typical temperatures for this climate.

When you’re choosing a new cooling system, learn both the SEER and EER ratings before you finalize your decision about system selection. A system with both high SEER and EER ratings will use less energy.
