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 few of these acronyms and other frequently used terms to be able to successfully research your purchase—especially the terms that help describe energy efficiency. Let’s learn some of these terms. What is EER? EER stands for “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the outdoor temperature is at or above a certain temperature. 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 probably familiar with ENERGY STAR certification, but it’s sometimes not explained very well. ENERGY STAR was established in 1992 by the U.S. Environmental Protection Agency. It was designed to protect the environment while saving 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 see the blue ENERGY STAR label while you’re looking 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 products with the greatest efficiency 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 the entire cooling season, rather than its efficiency at a certain 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 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. Of course you’ll find more acronyms and unfamiliar lingo when you are in the market for your air conditioner replacement, but you’ll be more prepared by being aquainted with these terms.
