What do different air conditioner ratings mean?

air conditioner ratingsWhen you’re shopping for a new air conditioner, the HVAC industry can feel as though it’s full of confusing acronyms and terms. And if you want to get the most out of your research, you’ll want to become familiar with some of the most common terms used for air conditioner ratings.

Many of the terms reference efficiency factors that can help you save money throughout the year. So when you have to consider an air conditioner replacement, be sure to refresh your memory on these terms.

What is EER?

The energy-efficiency ratio, or EER, measures how efficiently an air conditioner will run when the outdoor temperature is at a certain level. The higher the EER rating, the more efficient the air conditioner, so when you’re searching for air conditioner replacement look for higher ratings so you can enjoy all the savings they can bring you.

ENERGY STAR® Certification

Most consumers have heard about ENERGY STAR certifications. In 1992, the U.S. Environmental Protection Agency established ENERGY STAR to help consumers save money and protect the environment by using more energy efficient products. ENERGY STAR certification is earned through in-depth third-party testing, with products meeting a specific number of requirements to earn the rating. Look for the blue energy star logo when it’s time to replace your air conditioner.

SEER – Seasonal Energy Efficiency Ratio

SEER stands for Seasonal Energy Efficiency Ratio, and it measures the cooling efficiency of your a/c or heat pump. The higher the rating a product receives, the greater its energy efficiency. That also adds up to greater savings for you and less impact on the environment. SEER ratings will vary depending on the age of an air conditioner, going from as low as 8 on older products, to today’s range of 13-23.

The difference between EER and SEER is that SEER measures your air conditioner’s efficiency over the whole cooling season as opposed to a single outdoor temperature for EER.
