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 filled to the brim with acronyms and baffling terms. You’ll want to get acquainted with some of these acronyms and other common terms to be able to successfully research your purchase—notably the terms that help describe 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 outside temperature is at or above a certain degree. Look for 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’re most likely familiar with ENERGY STAR certification, but it’s sometimes not explained very well. ENERGY STAR was established in 1992 by the U.S. Environmental Protection Agency. The goal was to protect the environment while helping consumers save money on energy by using more energy-efficient products. Products must endure rigorous third-party testing and meet the many requirements to become ENERGY STAR certified. So, when you spot the blue ENERGY STAR label while you’re looking 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 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 big difference between SEER ratings and EER ratings is that SEER is the degree of an air conditioner’s efficiency over a complete 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 less of an impact on the environment. If your air conditioner is getting up there in age, the SEER rating could be as low as 8, while newer, more efficient models range from ratings of 13 – 23.

Of course you’ll find more acronyms and unfamiliar jargon when you are looking into your air conditioner replacement, but you’ll be more prepared by being aquainted with these terms.
