Understanding HVAC Ratings before an Air Conditioner Replacement 04/30/2015 When the time comes for air conditioner replacement, the HVAC industry can feel like 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. A number of the terms reference efficiency factors that can help you save money throughout the year. So next time you have to think through 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 defined level. The higher the EER rating, the higher the efficiency, so when you’re in the market for air conditioner replacement be sure to look for higher ratings so you can take advantage of all the savings they can bring you. ENERGY STAR® Certification Most consumers have heard of ENERGY STAR certifications, but rarely is it truly 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 in-depth third-party testing, and products must meet a defined 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 referenced 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 higher savings for you and less 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 most noticeable 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 realize that there are a lot more acronyms and terms than the few we’ve outlined here, but these will give you a greater understanding of a few common ones.
