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 riddled with acronyms and baffling terms. You’ll want to familiarize yourself with a few of these acronyms and other frequently used terms to be able to successfully research your purchase—especially the terms that help explain energy efficiency. Let’s look at some of these terms.

What is EER?

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

ENERGY STAR® Certification

You’re probably familiar with ENERGY STAR certification, but it’s commonly not explained very well. ENERGY STAR was started in 1992 by the U.S. Environmental Protection Agency. The objective was to protect the environment while at the same time saving consumer’s money on energy by using more energy-efficient products. Products must endure rigorous third-party testing and meet all of the requirements to become ENERGY STAR certified. So, when you spot the blue ENERGY STAR label while you’re shopping for an air conditioner replacement, you’ll know it’ll 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 each 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 most notable difference between SEER ratings and EER ratings is that SEER is the degree of an air conditioner’s efficiency over throughout the entire cooling season, rather than its efficiency at a certain 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 a decreased impact on the environment. If you have an older air conditioner, the SEER rating could be as low as 8, while recent, more efficient models range from ratings of 13 – 23.

It’s almost certain you’ll find more acronyms and unfamiliar terms when you are looking into your air conditioner replacement, but you’ll be more knowledgeable by understanding these terms.
