Explanation of SEER

When one is in the market for energy efficiency, finding effective and efficient appliances for cooling homes has the potential to save a lot of money. SEER ratings help to figure out which cooling systems are the most efficient.

What does SEER stand for?

The Seasonal Energy Efficiency Ratio rating system was developed as a performance standard by the combined efforts between the U.S. government and equipment manufacturers with the intent to create a rating system that is easily understood by the public.

What Do The Numbers Mean?

The number that is associated with a SEER rating measures the British thermal units per hour of cooling or heating, per watt of electricity. The higher the number, the more efficiently a product will produce cool air compared to a product with a lower number.

How Does It Work?

The higher the SEER rating, the more energy efficient an appliance is. In early 1990s, many cooling units carried a SEER rating of 6. Newer, high-efficiency units today typically have a rating of 12 or even higher.

Other Similar Ratings

EER is the Energy Efficiency Ratio, which measures the energy efficiency of a cooling system when the outside temperature is 95 degrees Fahrenheit or higher. This type of rating is especially critical for those considering new appliances in areas where summer temperatures are consistently at the higher end of the spectrum.

Relationship With Energy Star

SEER, as well as the EER, ratings are both included in the Energy Star specifications. While SEER more accurately represents the efficiency of an appliance on a seasonal basis, EER predicts the system’s ability to perform efficiently on peak days.
