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 confusing terms. You’ll want to get acquainted with some of these acronyms and other frequently used terms to be able to successfully research your purchase—particularly the terms that help interpret energy efficiency. Let’s go through some of these terms. What is EER? EER stands for “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the outside temperature is at or above a certain level. Look for higher ratings on this one because the higher the EER rating is, the greater 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. The goal was to protect the environment while at the same time saving consumer’s 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 shopping 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 higest efficiency 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) is a measure of your air conditioner’s or heat pump’s cooling efficiency. The major 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 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. It’s almost certain you’ll find more acronyms and unfamiliar terms when you are in the market for your air conditioner replacement, but you’ll be more knowledgeable by being aquainted with these terms.
