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 full of acronyms and confusing terms. You’ll want to become familiar with a number of these acronyms and other common terms to be able to successfully research your purchase—particularly the terms that help describe 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 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’re probably familiar with ENERGY STAR certification, but it’s not usually explained very well. ENERGY STAR was created 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 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 looking 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 most efficient products among those that are ENERGY STAR certified. These extraordinary 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 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 equals more money savings and a decreased 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. It’s almost certain you’ll find more acronyms and unfamiliar lingo when you are in the market for your air conditioner replacement, but you’ll be a lot more informed by knowing these terms.
