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 become familiar 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 look at some of these terms. What is EER? EER stands for “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the temperature outside is at or above a certain temperature. You’ll want 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’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. It was designed to protect the environment while saving money on energy by using more energy-efficient products. Products must undergo rigorous third-party testing and meet the many requirements to become ENERGY STAR certified. So, when you see the blue ENERGY STAR label while you’re looking for an air conditioner replacement, you can count on it saving you money. ENERGY STAR - Most Efficient The ENERGY STAR Most Efficient designation recognizes the most efficient products 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 designated temperature level. Like the EER ratings, higher the SEER ratings show the system has 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 recent, more efficient models range from ratings of 13 – 23. You’ll certainly find more acronyms and unfamiliar lingo when you are researching your air conditioner replacement, but you’ll be a lot more informed by being aquainted with these terms.
