Understanding HVAC Ratings before an Air Conditioner Replacement

April 30, 2015

When it comes time for air conditioner replacement, the HVAC industry can seem as though it’s full of acronyms and terms that may be a tad 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. A number of the terms reference efficiency factors that can help you save money month after month. So whenever you have to consider 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 work when the outdoor temperature is at a certain level. The higher the EER rating, the greater the efficiency, so when you’re searching for air conditioner replacement be sure to keep an eye out for higher ratings so you can take advantage of all the savings they can bring you.


ENERGY STAR® Certification

Most consumers have heard of ENERGY STAR certifications, but rarely is it truly explained. 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 rigorous 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 its packaging.

SEER – Seasonal Energy Efficiency Ratio

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

The most noticeable 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 find out that there are a lot more acronyms and terms than the few we’ve listed here, but these will give you a better understanding of a few common ones.
