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 baffling terms. You’ll want to get acquainted with a few of these acronyms and other frequently used terms to be able to successfully research your purchase—notably the terms that help interpret 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 degree. 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 seeing lower utility bills in no time. ENERGY STAR® Certification You’ve probably heard of ENERGY STAR certification, but it’s sometimes 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 endure rigorous third-party testing and meet a specific number of 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 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) is the degree 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 a measurement of an air conditioner’s efficiency over the entire cooling season, rather than its efficiency at a set temperature level. Like the EER ratings, higher the SEER ratings are an indication of better energy efficiency. More energy efficiency equates to more money savings and a decreased 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 lingo when you are researching your air conditioner replacement, but you’ll be more knowledgeable by being aquainted with these terms.
