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 baffling terms. You’ll want to familiarize yourself with a number of these acronyms and other typically used terms to be able to successfully research your purchase—particularly 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 level. Look for higher ratings on this one because the higher the EER rating is, the more energy efficient the model is. You could be seeing lower utility 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 started in 1992 by the U.S. Environmental Protection Agency. The goal was to protect the environment while saving money on energy by using more energy-efficient products. Products must undergo rigorous third-party testing and meet a specific number of requirements to become ENERGY STAR certified. So, when you spot 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 most efficient products among those that are ENERGY STAR certified. These phenomenal 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 most notable difference between SEER ratings and EER ratings is that SEER is a measurement of an air conditioner’s efficiency over a complete cooling season, rather than its efficiency at a set temperature level. Like the EER ratings, higher the SEER ratings mean better energy efficiency. More energy efficiency leads 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 current, more efficient models range from ratings of 13 – 23. Of course you’ll find more acronyms and unfamiliar terms when you are researching your air conditioner replacement, but you’ll be a lot more informed by understanding these terms.
