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 get acquainted with a number of these acronyms and other typically used terms to be able to successfully research your purchase—especially the terms that help interpret energy efficiency. Let’s look at 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 outdoor temperature is at or above a certain degree. Look for 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 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 saving 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 in the market 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 greatest efficiency 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 is the degree of 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 are an indication of better energy efficiency. More energy efficiency equals 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 current, 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 more knowledgeable by knowing these terms.
