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 familiarize yourself with some 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 go through 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 degree. Look for 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 commonly 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 helping consumers save 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 spot the blue ENERGY STAR label while you’re looking 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 higest efficiency among those that are ENERGY STAR certified. These phenomenal products represent the leading edge in energy efficient products year after 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 the entire cooling season, rather than its efficiency at a designated temperature level. Like the EER ratings, higher the SEER ratings show the system has better energy efficiency. More energy efficiency leads to more money savings and a decreased 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 in the market for your air conditioner replacement, but you’ll be a lot more informed by understanding these terms.
