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 perplexing terms. You’ll want to get acquainted with a number of these acronyms and other common 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 is an acronym for “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the temperature outside 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 saving money on energy in no time. ENERGY STAR® Certification You’re probably 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. It was designed to protect the environment while at the same time saving consumer’s money on energy by using more energy-efficient products. Products must pass 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 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 exceptional 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 big difference between SEER ratings and EER ratings is that SEER measures an air conditioner’s efficiency over throughout the entire cooling season, rather than its efficiency at a designated temperature level. Like the EER ratings, higher the SEER ratings are an indication of better energy efficiency. More energy efficiency equals more money savings and less of an 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. Of course you’ll find more acronyms and unfamiliar terms when you are researching your air conditioner replacement, but you’ll be more prepared by understanding these terms.
