Understanding HVAC Ratings before an Air Conditioner Replacement

April 30, 2015

When you’re looking into an air conditioner replacement, you’ll find that the HVAC industry is full of acronyms and perplexing terms. You’ll want to become familiar with a few of these acronyms and other frequently used terms to be able to successfully research your purchase—particularly the terms that help describe energy efficiency. Let’s look at some of these terms.

What is EER?

EER means “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the outside temperature is at or above a certain level. It’s best to go with the higher ratings on this one because the higher the EER rating is, the more energy efficient the model is. You could be seeing lower utility bills in no time.

ENERGY STAR® Certification

You’ve probably heard of ENERGY STAR certification, but it’s not usually explained very well. ENERGY STAR was started in 1992 by the U.S. Environmental Protection Agency. It was designed to protect the environment while helping consumers save money on energy by using more energy-efficient products. Products must pass rigorous third-party testing and meet the many requirements to become ENERGY STAR certified. So, when you notice the blue ENERGY STAR label while you’re in the market for an air conditioner replacement, you’ll be certain it will save you money.

ENERGY STAR - Most Efficient

The ENERGY STAR Most Efficient designation recognizes the products with the greatest efficiency among those that are ENERGY STAR certified. These exceptional products represent the leading edge in energy efficient products every year.

SEER – Seasonal Energy Efficiency Ratio

The Seasonal Energy Efficiency Ratio (SEER) is a measure of your air conditioner’s or heat pump’s cooling efficiency. The major difference between SEER ratings and EER ratings is that SEER is a measurement of an air conditioner’s efficiency over a complete cooling season, rather than its efficiency at a set temperature level. Like the EER ratings, higher the SEER ratings show the system has better energy efficiency. More energy efficiency equals more money savings and less of an impact on the environment. If you’ve had your air conditioner for a while, the SEER rating could be as low as 8, while current, more efficient models range from ratings of 13 – 23.

Of course you’ll find more acronyms and unfamiliar terms when you are in the market for your air conditioner replacement, but you’ll be more knowledgeable by understanding these terms.
