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 some of these acronyms and other typically used terms to be able to successfully research your purchase—especially the terms that help explain energy efficiency. Let’s go through 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. 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 saving money on energy in no time. ENERGY STAR® Certification You’re probably familiar with ENERGY STAR certification, but it’s not usually explained very well. ENERGY STAR was started in 1992 by the U.S. Environmental Protection Agency. The objective was to protect the environment while at the same time saving consumer’s money on energy by using more energy-efficient products. Products must undergo rigorous third-party testing and meet the many requirements to become ENERGY STAR certified. So, when you notice the blue ENERGY STAR label while you’re looking 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 products with the higest efficiency among those that are ENERGY STAR certified. These exceptional products represent the leading edge in energy efficient products every 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 big difference between SEER ratings and EER ratings is that SEER is a measurement of 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 mean 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 newer, more efficient models range from ratings of 13 – 23. It’s almost certain you’ll find more acronyms and unfamiliar lingo when you are in the market for your air conditioner replacement, but you’ll be more knowledgeable by being aquainted with these terms.
