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 confusing terms. You’ll want to familiarize yourself with a number of these acronyms and other typically used terms to be able to successfully research your purchase—particularly 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 outside temperature is at or above a certain temperature. 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’re most likely 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. The objective was to protect the environment while helping consumers save money on energy by using more energy-efficient products. Products must endure 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 in the market 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 most efficient products among those that are ENERGY STAR certified. These exceptional products represent the leading edge in energy efficient products each 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 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 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. It’s almost certain you’ll find more acronyms and unfamiliar jargon when you are in the market for your air conditioner replacement, but you’ll be more prepared by being aquainted with these terms.
