Understanding HVAC Ratings before an Air Conditioner Replacement

April 30, 2015

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 become familiar with a few of these acronyms and other typically used terms to be able to successfully research your purchase—particularly the terms that help explain energy efficiency. Let’s learn some of these terms.

What is EER?

EER means “energy-efficiency ratio.” It measures the energy efficiency of an air conditioner when the temperature outside is at or above a certain degree. It’s best to go with the higher ratings on this one because the higher the EER rating is, the higher the energy efficiency. You could be seeing lower utility bills 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 established in 1992 by the U.S. Environmental Protection Agency. The objective was to protect the environment while saving money on energy by using more energy-efficient products. Products must pass rigorous third-party testing and meet all of the 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’ll be certain it will save you money.

ENERGY STAR - Most Efficient

The ENERGY STAR Most Efficient designation recognizes the most efficient products among those that are ENERGY STAR certified. These phenomenal products represent the leading edge in energy efficient products each year.

SEER – Seasonal Energy Efficiency Ratio

The Seasonal Energy Efficiency Ratio (SEER) represents a measurement 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 the degree of an air conditioner’s efficiency over the entire cooling season, rather than its efficiency at a certain temperature level. Like the EER ratings, higher the SEER ratings are an indication of better energy efficiency. More energy efficiency equates to more money savings and a lower impact on the environment. If you’ve had your air conditioner for a while, the SEER rating could be as low as 8, while current, more efficient models range from ratings of 13 – 23.

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