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 some of these acronyms and other frequently used terms to be able to successfully research your purchase—notably the terms that help interpret energy efficiency. Let’s go through 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 more energy efficient the model is. You could be paying less on your energy bills in no time.

ENERGY STAR® Certification

You’re probably familiar with ENERGY STAR certification, but it’s not usually explained very well. ENERGY STAR was started in 1992 by the U.S. Environmental Protection Agency. It was designed to protect the environment while at the same time saving consumer’s money on energy by using more energy-efficient products. Products must undergo rigorous third-party testing and meet a specific number of requirements to become ENERGY STAR certified. So, when you spot the blue ENERGY STAR label while you’re looking 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 greatest efficiency among those that are ENERGY STAR certified. These extraordinary products represent the leading edge in energy efficient products every 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 big difference between SEER ratings and EER ratings is that SEER measures an air conditioner’s efficiency over throughout 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 leads 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 being aquainted with these terms.
