Understanding HVAC Ratings before an Air Conditioner Replacement

When the time comes for air conditioner replacement, the HVAC industry can feel as though it’s full of acronyms and terms that may be a little confusing. However, if you want to get the most out of all the research you’re doing, you’ll want to familiarize yourself with some of the most common terms. Quite a few of the terms reference efficiency factors that can help you save money month after month. So next time you have to think through an air conditioner replacement, be sure to refresh your memory on these terms.

What is EER?

The EER, or energy-efficiency ratio, measures how efficiently the air conditioner will operate when the outdoor temperature is at a specific level. The higher the EER rating, the more efficient, so when you’re in the market for air conditioner replacement be sure to keep an eye out for higher ratings so you can realize all the savings they can bring you.


ENERGY STAR® Certification

Most consumers know about ENERGY STAR certifications, but rarely is it really clarified. In 1992, the U.S. Environmental Protection Agency established ENERGY STAR to help consumers save money on their energy expenses and protect the environment by using more energy efficient products. ENERGY STAR certification is earned through in-depth third-party testing, and products must meet a defined number of requirements. So when it’s time for air conditioner replacement, make sure to look for the blue label with the ENERGY STAR logo on the package.

SEER – Seasonal Energy Efficiency Ratio

The Seasonal Energy Efficiency Ratio, typically stated as SEER, measures the cooling efficiency of your air conditioner or heat pump. Again, the higher the rating a product receives, the better the energy efficiency. That also means higher savings for you and a lower impact on the environment. SEER ratings can greatly rely on the age of your current air conditioner, going from as low as 8 on older products, to today’s range of 13-23.

The biggest difference between EER and SEER is that SEER measures your air conditioner’s efficiency over an entire cooling season versus only one outdoor temperature like EER.

When searching for an air conditioner replacement, you’ll quickly learn that there are a lot more acronyms and terms than the few we’ve outlined here, but these will give you a better understanding of a few common ones.
