Understanding HVAC Ratings before an Air Conditioner Replacement 04/30/2015 When it’s time for air conditioner replacement, the HVAC industry can seem as though it’s full of acronyms and terms that may be a little 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. Quite a few of the terms reference efficiency factors that can help you save money during the entire year. So next time you have to think about 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 more efficient, so when you’re searching for air conditioner replacement be sure to keep an eye out for 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 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 certain 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, usually stated as SEER, measures the cooling efficiency of your air conditioner or heat pump. Again, the higher the rating a product receives, the greater the energy efficiency. That also means more savings for you and a lower impact on the environment. SEER ratings can greatly vary depending 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 biggest 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 searching for an air conditioner replacement, you’ll quickly find out that there are a lot more acronyms and terms than the couple we’ve outlined here, but these will give you a greater understanding of a few common ones.
