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 perplexing terms. You’ll want to get acquainted with some of these acronyms and other typically used terms to be able to successfully research your purchase—especially the terms that help explain energy efficiency. Let’s learn 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 temperature. 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’re probably familiar with ENERGY STAR certification, but it’s sometimes not explained very well. ENERGY STAR was created 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 pass rigorous third-party testing and meet all of the requirements to become ENERGY STAR certified. So, when you notice 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 phenomenal products represent the leading edge in energy efficient products every year. SEER – Seasonal Energy Efficiency Ratio The Seasonal Energy Efficiency Ratio (SEER) is the degree of your air conditioner’s or heat pump’s cooling efficiency. The big 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 designated 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 recent, more efficient models range from ratings of 13 – 23. Of course 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.
