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 perplexing terms. You’ll want to become familiar with a number of these acronyms and other common terms to be able to successfully research your purchase—especially the terms that help describe 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 more energy efficient the model is. You could be paying less on your energy bills in no time. ENERGY STAR® Certification You’re probably familiar with ENERGY STAR certification, but it’s commonly not explained very well. ENERGY STAR was created in 1992 by the U.S. Environmental Protection Agency. It was designed to protect the environment while helping consumers save money on energy by using more energy-efficient products. Products must pass 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 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 most efficient products among those that are ENERGY STAR certified. These extraordinary products represent the leading edge in energy efficient products every 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 the entire cooling season, rather than its efficiency at a certain temperature level. Like the EER ratings, higher the SEER ratings mean better energy efficiency. More energy efficiency equates to more money savings and a decreased 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. You’ll certainly find more acronyms and unfamiliar jargon when you are researching your air conditioner replacement, but you’ll be more prepared by knowing these terms.
