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 confusing terms. You’ll want to get acquainted with a few of these acronyms and other typically used terms to be able to successfully research your purchase—especially the terms that help explain 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 outdoor temperature is at or above a certain level. 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 most likely familiar with ENERGY STAR certification, but it’s commonly not 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 the many requirements to become ENERGY STAR certified. So, when you notice the blue ENERGY STAR label while you’re shopping 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 highest efficiency 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 major difference between SEER ratings and EER ratings is that SEER measures an air conditioner’s efficiency over a complete cooling season, rather than its efficiency at a set temperature level. Like the EER ratings, higher the SEER ratings mean better energy efficiency. More energy efficiency equates to more money savings and a decreased impact on the environment. If your air conditioner is getting up there in age, the SEER rating could be as low as 8, while newer, more efficient models range from ratings of 13 – 23.

It’s almost certain you’ll find more acronyms and unfamiliar lingo when you are in the market for your air conditioner replacement, but you’ll be more knowledgeable by knowing these terms.
