Understanding HVAC Ratings before an Air Conditioner Replacement 04/30/2015 When you’re looking into an air conditioner replacement, you’ll find that the HVAC industry is filled to the brim with acronyms and confusing terms. You’ll want to get acquainted with some of these acronyms and other typically used terms to be able to successfully research your purchase—particularly the terms that help explain energy efficiency. Let’s learn some of these terms. What is EER? EER means “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the temperature outside is at or above a certain level. Look for 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 sometimes not explained very well. ENERGY STAR was established 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 undergo rigorous third-party testing and meet a specific number of requirements to become ENERGY STAR certified. So, when you notice 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 higest efficiency among those that are ENERGY STAR certified. These phenomenal products represent the leading edge in energy efficient products year after year. SEER – Seasonal Energy Efficiency Ratio The Seasonal Energy Efficiency Ratio (SEER) is the degree of your air conditioner’s or heat pump’s cooling efficiency. The big 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 designated temperature level. Like the EER ratings, higher the SEER ratings are an indication of better energy efficiency. More energy efficiency equates to more money savings and a lower 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. Of course you’ll find more acronyms and unfamiliar lingo when you are looking into your air conditioner replacement, but you’ll be more prepared by being aquainted with these terms.
