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 become familiar with a few 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 is an acronym for “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the outside temperature is at or above a certain degree. Look for higher ratings on this one because the higher the EER rating is, the more energy efficient the model is. You could be paying less on your energy 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 started in 1992 by the U.S. Environmental Protection Agency. It was designed to protect the environment while at the same time saving consumer’s money on energy by using more energy-efficient products. Products must pass rigorous third-party testing and meet the many requirements to become ENERGY STAR certified. So, when you spot the blue ENERGY STAR label while you’re shopping 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 products with the greatest efficiency among those that are ENERGY STAR certified. These extraordinary products represent the leading edge in energy efficient products every year. SEER – Seasonal Energy Efficiency Ratio The Seasonal Energy Efficiency Ratio (SEER) represents a measurement 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 the degree of an air conditioner’s efficiency over a complete cooling season, rather than its efficiency at a certain temperature level. Like the EER ratings, higher the SEER ratings mean better energy efficiency. More energy efficiency equates 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. You’ll certainly find more acronyms and unfamiliar jargon when you are in the market for your air conditioner replacement, but you’ll be a lot more informed by understanding these terms.
