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 baffling terms. You’ll want to familiarize yourself with a number of these acronyms and other common terms to be able to successfully research your purchase—particularly the terms that help describe energy efficiency. Let’s go through 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 outdoor temperature is at or above a certain level. 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 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. The objective 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 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 extraordinary products represent the leading edge in energy efficient products every 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 most notable difference between SEER ratings and EER ratings is that SEER is the degree 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 leads to more money savings and a lower 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. Of course you’ll find more acronyms and unfamiliar jargon when you are researching your air conditioner replacement, but you’ll be a lot more informed by being aquainted with these terms.
