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 baffling terms. You’ll want to get acquainted with a number of these acronyms and other common terms to be able to successfully research your purchase—especially the terms that help interpret energy efficiency. Let’s learn some of these terms. What is EER? EER means “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the outside temperature is at or above a certain level. Look for higher ratings on this one because the higher the EER rating is, the higher the energy efficiency. You could be saving money on energy in no time. ENERGY STAR® Certification You’re most likely 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 a specific number of 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 most efficient products among those that are ENERGY STAR certified. These exceptional 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 a measurement of an air conditioner’s efficiency over throughout the entire cooling season, rather than its efficiency at a set temperature level. Like the EER ratings, higher the SEER ratings show the system has better energy efficiency. More energy efficiency equals more money savings and a lower impact on the environment. If you’ve had your air conditioner for a while, 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 terms when you are researching your air conditioner replacement, but you’ll be a lot more informed by understanding these terms.
