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 confusing terms. You’ll want to become familiar with a number 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 means “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the outdoor temperature is at or above a certain degree. It’s best to go with the 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 commonly not 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 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’ll be certain it will 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 year after 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 big difference between SEER ratings and EER ratings is that SEER measures 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 leads to more money savings and a lower impact on the environment. If your air conditioner is getting up there in age, the SEER rating could be as low as 8, while newer, more efficient models range from ratings of 13 – 23. You’ll certainly find more acronyms and unfamiliar terms when you are looking into your air conditioner replacement, but you’ll be a lot more informed by being aquainted with these terms.
