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 baffling terms. You’ll want to become familiar with some of these acronyms and other common terms to be able to successfully research your purchase—notably the terms that help interpret 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 level. You’ll want 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’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. The objective was to protect the environment while saving 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 notice the blue ENERGY STAR label while you’re shopping for an air conditioner replacement, you’ll know it’ll save 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 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 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 a lower impact on the environment. If you’ve had your air conditioner for a while, the SEER rating could be as low as 8, while current, more efficient models range from ratings of 13 – 23. You’ll certainly find more acronyms and unfamiliar jargon when you are in the market for your air conditioner replacement, but you’ll be more prepared by understanding these terms.
