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 common terms to be able to successfully research your purchase—notably the terms that help explain energy efficiency. Let’s look at some of these terms. What is EER? EER means “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the outdoor temperature is at or above a certain temperature. 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 most likely familiar with ENERGY STAR certification, but it’s commonly not explained very well. ENERGY STAR was established in 1992 by the U.S. Environmental Protection Agency. It was designed to protect the environment while at the same time saving consumer’s money on energy by using more energy-efficient products. Products must endure 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 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 extraordinary 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 big difference between SEER ratings and EER ratings is that SEER measures an air conditioner’s efficiency over throughout 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 leads to more money savings and a lower impact on the environment. If you have an older air conditioner, the SEER rating could be as low as 8, while recent, 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 more knowledgeable by understanding these terms.
