Understanding HVAC Ratings before an Air Conditioner Replacement

When you’re looking into an air conditioner replacement, you’ll find that the HVAC industry is full of acronyms and baffling terms. You’ll want to get acquainted with a number of these acronyms and other common terms to be able to successfully research your purchase—particularly the terms that help describe energy efficiency. Let’s look at some of these terms.

What is EER?

EER is an acronym for “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the temperature outside is at or above a certain level. Look for higher ratings on this one because the higher the EER rating is, the higher the energy efficiency. You could be saving money on energy in no time.

ENERGY STAR® Certification

You’ve probably heard of ENERGY STAR certification, but it’s not usually explained very well. ENERGY STAR was created in 1992 by the U.S. Environmental Protection Agency. It was designed to protect the environment while saving money on energy by using more energy-efficient products. Products must endure rigorous third-party testing and meet a specific number of requirements to become ENERGY STAR certified. So, when you see the blue ENERGY STAR label while you’re in the market for an air conditioner replacement, you can count on it saving you money.

ENERGY STAR - Most Efficient

The ENERGY STAR Most Efficient designation recognizes the products with the higest efficiency among those that are ENERGY STAR certified. These extraordinary products represent the leading edge in energy efficient products year after year.

SEER – Seasonal Energy Efficiency Ratio

The Seasonal Energy Efficiency Ratio (SEER) is a measure of your air conditioner’s or heat pump’s cooling efficiency. The most notable difference between SEER ratings and EER ratings is that SEER is a measurement of an air conditioner’s efficiency over the entire cooling season, rather than its efficiency at a designated temperature level. Like the EER ratings, higher the SEER ratings are an indication of better energy efficiency. More energy efficiency equals more money savings and less of an impact on the environment. If you have an older air conditioner, the SEER rating could be as low as 8, while newer, more efficient models range from ratings of 13 – 23.

Of course you’ll find more acronyms and unfamiliar lingo when you are looking into your air conditioner replacement, but you’ll be more knowledgeable by understanding these terms.
