This article is your comprehensive guide to the Seasonal Energy Efficiency Ratio (SEER). SEER stands for Seasonal Energy Efficiency Ratio, a metric used to measure the efficiency of air conditioning units. It represents the ratio of the cooling output (measured in BTUs) over a typical cooling season, divided by the total energy input in watt-hours during that same period

What is the Seasonal Energy Efficiency Ratio?
The Seasonal Energy Efficiency Ratio (SEER) is a measure used to gauge the efficiency of air conditioning systems or heat pumps. It’s a ratio of the cooling output of an air conditioner over a typical cooling season divided by the energy it consumes in Watt-Hours. In simpler terms, SEER is a measure of how much cool air your air conditioning system can produce per unit of energy it consumes. The higher the SEER rating of an air conditioner, the more energy-efficient it is.
Why Does SEER Matter?
SEER matters because it directly impacts the energy consumption and operating cost of your air conditioning unit. A higher SEER rating means that the unit is more efficient, which can result in lower energy bills. It’s an important factor to consider when purchasing a new air conditioner or heat pump, as it can help you balance the upfront cost of the system with the ongoing energy costs.
What’s the Difference Between SEER and Energy Efficiency Ratio (EER)?
Seasonal Energy Efficiency:
The Energy Efficiency Ratio measures the energy efficiency of an air conditioner at a specific, constant temperature. It’s a snapshot of your air conditioner’s efficiency at peak operating conditions.
Energy Efficiency Ratio:
The Seasonal Energy Efficiency Ratio measures the efficiency of an air conditioner at various temperatures, reflecting the unit’s performance throughout an entire cooling season. This means SEER takes into account the fluctuations in temperature throughout the season and provides a more comprehensive view of your air conditioner’s overall efficiency.
What’s the Difference Between SEER and SEER2?
SEER2 is a newer rating system that provides a more accurate measure of an air conditioner’s efficiency over the entire cooling season. While the original SEER rating only considers the unit’s efficiency at a single outdoor temperature, SEER2 takes into account a range of temperatures, reflecting the unit’s performance more accurately.

What are the Benefits of a High SEER Rating or Ratio?
A higher SEER rating on air conditioning units SEER rating signifies a more energy-efficient system, which can cool spaces faster and save 20%-40% of cooling energy costs, according to the U.S. Department of Energy. These efficient systems also contribute to a smaller carbon footprint by reducing greenhouse gas emissions from power plants. Additionally, high SEER-rated units may qualify for state and national rebates, making them more affordable. They are also adept at removing moisture, improving indoor air quality, and potentially benefiting those with allergies or respiratory conditions
Benefits of a High SEER Rating
- Lower energy bills with better air conditioner efficiency
- Reduce your carbon footprint
- Incentives and Rebates
Lower Energy Bills and Electricity Consumption
A high SEER rating can significantly reduce your overall energy consumption, which leads to lower utility bills. This is particularly beneficial in the summer months when air conditioning units are in constant use. This is because a high SEER unit can cool a space more quickly, which means less time running and using energy.
Reduce your carbon footprint
A high SEER AC unit is much more energy efficient, which means it uses less energy to cool your home or small business. By using less electricity for cooling, a high SEER air conditioner indirectly reduces the amount of fossil fuels burned to generate that electricity, thereby reducing the greenhouse gas emissions associated with your energy use.
Government incentives and rebates
High SEER-rated air conditioners do tend to cost more than less efficient air conditioners, which can be a concern for some. Because of that reason, the government offers incentives and rebates for consumers, making them more affordable. So, a high SEER air conditioner could potentially save you money upfront as well as in the long run.

What is the Best SEER for Your Home?
Choosing the best SEER for your home depends on several factors, including your local climate, the size of your home, and your budget. Typically, a good SEER rating would be more than 16, but there are models with SEER ratings from 14 – 20 or higher! With that being said, the minimum SEER rating required by the U.S. Department of Energy is 13 or 14, depending on where you live.
What’s a good SEER rating?
Opting for an air conditioner with a good SEER rating, typically between 14 and 16, can significantly enhance energy efficiency and lead to long-term savings on energy bills. High-efficiency models, with SEER ratings of 20 or higher, offer additional benefits such as variable-speed cooling, which ensures consistent temperature control, eliminates cool spots, and reduces humidity, thereby improving your home’s comfort and indoor air quality. Choosing a high-SEER unit isn’t just about picking the highest number available; it’s about finding a cost-effective balance that maximizes energy savings while enhancing the comfort level of your home.

Is a High-SEER Air Conditioner Right for You?
When deciding whether a high-SEER air conditioner is right for you, it’s essential to consider your specific needs and circumstances. While a high-SEER unit can offer significant energy savings and enhanced comfort, it’s not always the best choice for every homeowner.
High-SEER air conditioners often come with a higher upfront cost compared to their lower-SEER counterparts. However, the energy savings they provide can offset this initial cost over time, making them a cost-effective choice in the long run. This is particularly true if you live in a region with hot summers, where your air conditioner is likely to be in heavy use.
Another factor to consider is the comfort and indoor air quality that high-SEER units can provide. Many high-efficiency units offer variable-speed cooling, which can provide more consistent temperature control, prevent cool spots, and reduce humidity levels in your home. If you value these comfort features, a high-SEER unit could be a worthwhile investment.
However, the benefits of a high-SEER unit will only be fully realized if the unit is properly sized for your home and correctly installed. An oversized or improperly installed unit can lead to reduced efficiency, frequent cycling, and uneven cooling. Therefore, it’s crucial to work with a knowledgeable HVAC professional who can correctly size and install your air conditioner.

SEER Ratings FAQ
Q: What is a good energy efficiency ratio for air conditioners?
A: A good energy efficiency ratio (EER) for air conditioners is typically between 8 and 12. Like SEER, a higher EER rating means the unit is more energy-efficient.
Q: What is the system’s Seasonal Energy Efficiency Ratio?
A: The system Seasonal Energy Efficiency Ratio is the SEER rating for the entire HVAC system, including the air conditioner and any associated components like the air handler or furnace.
Q: What is the new minimum SEER rating in 2024?
A: As of 2024, the U.S. Department of Energy has proposed increasing the minimum SEER rating for new air conditioners to 14 in all regions of the country.
Q: How much more efficient is a 20 SEER vs 14 SEER?
A: A 20 SEER air conditioner is about 30% more efficient than a 14 SEER unit. This means it could potentially save you about 30% on your cooling costs, although actual savings will depend on your usage and local energy rates.
