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 riddled with acronyms and baffling terms. You’ll want to get acquainted with a number 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 go through some of these terms. What is EER? EER stands for “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 greater the energy efficiency. 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 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 all of the requirements to become ENERGY STAR certified. So, when you see 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 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 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 measures an air conditioner’s efficiency over throughout the entire cooling season, rather than its efficiency at a set 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 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. It’s almost certain you’ll find more acronyms and unfamiliar terms when you are researching your air conditioner replacement, but you’ll be more prepared by being aquainted with these terms.
