Understanding HVAC Ratings before an Air Conditioner Replacement 04/30/2015 When it comes time for air conditioner replacement, the HVAC industry can seem as though it’s full of acronyms and terms that may be a tad confusing. However, if you want to get the most out of all the research you’re doing, you’ll want to familiarize yourself with some of the most common terms. A number 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 run when the outdoor temperature is at a defined level. The higher the EER rating, the greater the efficiency, 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 know about ENERGY STAR certifications, but rarely is it truly defined. 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 box. SEER – Seasonal Energy Efficiency Ratio The Seasonal Energy Efficiency Ratio, typically referenced as SEER, measures the cooling efficiency of your air conditioner or heat pump. Again, the higher the rating a product has, the higher the energy efficiency. That also means more savings for you and a smaller impact on the environment. SEER ratings can greatly depend on the age of your current air conditioner, stretching from as low as 8 on older products, to today’s range of 13-23. The most noticeable difference between EER and SEER is that SEER measures your air conditioner’s efficiency over an entire cooling season versus one outdoor temperature like EER. When you’re in the market for an air conditioner replacement, you’ll quickly find out that there are a lot more acronyms and terms than the couple we’ve listed here, but these will give you a better understanding of a few common ones.
