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 riddled with acronyms and perplexing terms. You’ll want to get acquainted with a few of these acronyms and other common terms to be able to successfully research your purchase—notably the terms that help describe energy efficiency. Let’s look at some of these terms. What is EER? EER means “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the outdoor temperature is at or above a certain temperature. It’s best to go with the higher ratings on this one because the higher the EER rating is, the higher 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 goal 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 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 most efficient products among those that are ENERGY STAR certified. These phenomenal 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 most notable difference between SEER ratings and EER ratings is that SEER measures an air conditioner’s efficiency over the entire 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 equals 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 current, more efficient models range from ratings of 13 – 23. Of course you’ll find more acronyms and unfamiliar terms when you are in the market for your air conditioner replacement, but you’ll be more prepared by being aquainted with these terms.
