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 become familiar with a few 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 look at 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. 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 commonly not explained very well. ENERGY STAR was started 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 the many 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 higest efficiency among those that are ENERGY STAR certified. These extraordinary products represent the leading edge in energy efficient products year after 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 certain temperature level. Like the EER ratings, higher the SEER ratings mean better energy efficiency. More energy efficiency leads to 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 newer, more efficient models range from ratings of 13 – 23. You’ll certainly find more acronyms and unfamiliar jargon when you are researching your air conditioner replacement, but you’ll be more knowledgeable by being aquainted with these terms.
