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 filled to the brim with acronyms and confusing terms. You’ll want to get acquainted with some 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 is an acronym for “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the temperature outside 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 higher the energy efficiency. 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 created 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 all of the 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 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 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. It’s almost certain you’ll find more acronyms and unfamiliar terms when you are looking into your air conditioner replacement, but you’ll be a lot more informed by being aquainted with these terms.
