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 some of these acronyms and other typically used terms to be able to successfully research your purchase—particularly 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 temperature outside is at or above a certain temperature. It’s best 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. The objective 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 the many requirements to become ENERGY STAR certified. So, when you see the blue ENERGY STAR label while you’re in the market for an air conditioner replacement, you can count on it saving 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 big 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 designated temperature level. Like the EER ratings, higher the SEER ratings show the system has 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 current, more efficient models range from ratings of 13 – 23. It’s almost certain you’ll find more acronyms and unfamiliar jargon when you are looking into your air conditioner replacement, but you’ll be more knowledgeable by understanding these terms.
