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 get acquainted with a few of these acronyms and other frequently used terms to be able to successfully research your purchase—notably the terms that help explain energy efficiency. Let’s go through some of these terms. What is EER? EER means “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the temperature outside is at or above a certain degree. You’ll want to go with the higher ratings on this one because the higher the EER rating is, the greater the energy efficiency. You could be paying less on your energy bills in no time. ENERGY STAR® Certification You’re most likely familiar with ENERGY STAR certification, but it’s not usually explained very well. ENERGY STAR was established 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 see the blue ENERGY STAR label while you’re shopping 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 exceptional products represent the leading edge in energy efficient products each year. SEER – Seasonal Energy Efficiency Ratio The Seasonal Energy Efficiency Ratio (SEER) is the degree of your air conditioner’s or heat pump’s cooling efficiency. The big difference between SEER ratings and EER ratings is that SEER is the degree of an air conditioner’s efficiency over a complete cooling season, rather than its efficiency at a designated temperature level. Like the EER ratings, higher the SEER ratings show the system has better energy efficiency. More energy efficiency equates to more money savings and a lower impact on the environment. If your air conditioner is getting up there in age, 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 lingo when you are looking into your air conditioner replacement, but you’ll be a lot more informed by being aquainted with these terms.
