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 baffling terms. You’ll want to get acquainted with a few of these acronyms and other typically used terms to be able to successfully research your purchase—especially 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 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 higher the energy efficiency. You could be paying less on your energy bills in no time. ENERGY STAR® Certification You’ve probably heard of 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 saving money on energy by using more energy-efficient products. Products must undergo 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 shopping 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 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 the entire cooling season, rather than its efficiency at a certain temperature level. Like the EER ratings, higher the SEER ratings are an indication of better energy efficiency. More energy efficiency leads to more money savings and less of an impact on the environment. If you have an older air conditioner, the SEER rating could be as low as 8, while current, more efficient models range from ratings of 13 – 23. It’s almost certain you’ll find more acronyms and unfamiliar terms when you are in the market for your air conditioner replacement, but you’ll be a lot more informed by knowing these terms.
