Understanding HVAC Ratings before an Air Conditioner Replacement 04/30/2015 When it comes time for air conditioner replacement, the HVAC industry can feel like it’s full of acronyms and terms that may be a bit confusing. However, if you want to get the most out of all the research you’re doing, you’ll want to acquaint yourself with some of the most common terms. A lot of the terms reference efficiency factors that can help you save money during the entire year. So when you have to consider an air conditioner replacement, be sure to refresh your memory on these terms. What is EER? The EER, or energy-efficiency ratio, measures how efficiently the air conditioner will work when the outdoor temperature is at a certain level. The higher the EER rating, the more efficient, so when you’re in the market for air conditioner replacement be sure to try to find higher ratings so you can take advantage of all the savings they can bring you. ENERGY STAR® Certification Most consumers are familiar with ENERGY STAR certifications, but rarely is it actually explained. In 1992, the U.S. Environmental Protection Agency established ENERGY STAR to help consumers save money on their energy expenses and protect the environment by using more energy efficient products. ENERGY STAR certification is earned through thorough third-party testing, and products must meet a specific number of requirements. So when it’s time for air conditioner replacement, make sure to look for the blue label with the ENERGY STAR logo on the package. SEER – Seasonal Energy Efficiency Ratio The Seasonal Energy Efficiency Ratio, usually referred to as SEER, measures the cooling efficiency of your air conditioner or heat pump. Again, the higher the rating a product receives, the higher the energy efficiency. That also means higher savings for you and a lower impact on the environment. SEER ratings can greatly rely on the age of your current air conditioner, going from as low as 8 on older products, to today’s range of 13-23. The largest difference between EER and SEER is that SEER measures your air conditioner’s efficiency over an entire cooling season versus only one outdoor temperature like EER. When looking for an air conditioner replacement, you’ll quickly learn that there are a lot more acronyms and terms than the few we’ve listed here, but these will give you a better understanding of a few common ones.
