Understanding HVAC Ratings before an Air Conditioner Replacement 04/30/2015 When the time comes 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. Quite a few of the terms reference efficiency factors that can help you save money month after month. So next time 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 operate when the outdoor temperature is at a certain level. The higher the EER rating, the greater the efficiency, so when you’re looking for air conditioner replacement be sure to look for higher ratings so you can realize 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 rigorous 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 gets, the higher the energy efficiency. That also means more savings for you and less impact on the environment. SEER ratings can greatly depend 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 a single 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 good understanding of a few common ones.
