Understanding HVAC Ratings before an Air Conditioner Replacement

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 bit confusing. However, if you want to get the most out of all the research you’re doing, you’ll want to become familiar with some of the most common terms. A number of the terms reference efficiency factors that can help you save money month after month. So whenever 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 defined level. The higher the EER rating, the higher the efficiency, so when you’re searching for air conditioner replacement be sure to try to find higher ratings so you can realize all the savings they can bring you.


ENERGY STAR® Certification

Most consumers have heard of ENERGY STAR certifications, but rarely is it really 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 in-depth 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, 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 greater the energy efficiency. That also means greater savings for you and a smaller 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 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 learn that there are a lot more acronyms and terms than the few we’ve noted here, but these will give you a good understanding of a few common ones.
