Definition
The Seasonal Energy Efficiency Ratio (SEER) is a measure used to quantify the energy efficiency of air-conditioning equipment. Specifically, it represents the ratio of the amount of cooling produced (measured in British Thermal Units, or BTUs) to the amount of energy consumed (measured in watt-hours) over a seasonal period. The SEER rating allows consumers to compare the energy efficiency of different air conditioning systems and helps in reducing energy costs and environmental impacts.
Examples
Example 1: Minimum SEER Requirements
In the United States, residential air conditioners manufactured after 2005 must have a SEER rating of at least 13. This standard ensures that newer air-conditioning systems are more energy-efficient and consume less power compared to older models.
Example 2: Comparing SEER Ratings
Consider two air conditioning units: one with a SEER rating of 13 and another with a SEER rating of 16. The unit with a SEER rating of 16 is more energy-efficient, meaning it provides the same amount of cooling but consumes less energy, leading to lower utility bills over time.
Frequently Asked Questions (FAQs)
What does SEER stand for?
SEER stands for Seasonal Energy Efficiency Ratio.
How is SEER calculated?
SEER is calculated by dividing the cooling output during a typical cooling season (measured in BTUs) by the total electric energy input (measured in watt-hours) during the same period.
What is a good SEER rating for an air conditioner?
A higher SEER rating indicates better energy efficiency. As of 2021, a SEER rating of 14 to 16 is considered good for residential air conditioners.
Why is SEER important?
The SEER rating is important because it helps consumers choose energy-efficient air conditioning systems, which can significantly reduce energy consumption, lower environmental impact, and save money on utility bills.
Can SEER ratings vary by location?
Yes, SEER requirements can vary by region due to different climate conditions. For instance, warmer climates might require higher minimum SEER ratings.

Energy Efficiency Ratio (EER) measures the cooling efficiency of an air conditioner at a specific outdoor temperature. It is similar to SEER but typically calculated under more stable conditions.
Heating Seasonal Performance Factor (HSPF)
Heating Seasonal Performance Factor (HSPF) is a measure of the efficiency of heat pumps in their heating mode over an entire heating season.
British Thermal Unit (BTU)

Watt-Hour (Wh)
Watt-Hour (Wh) is a unit of energy equivalent to one watt of power expended for one hour.
