Why Are SEER Ratings Important When Choosing an Air Conditioner?

Learn More About SEER Ratings and How They Affect Your Home Comfort

When choosing an air conditioner for your home, one factor to consider is the SEER rating, which stands for Seasonal Energy Efficiency Ratio. It's a measure of an air conditioning unit's cooling efficiency over a typical cooling season. While higher SEER ratings offer better efficiency, the best choice depends on factors like your climate, home size, and budget. Generally, a good SEER rating is 14 or higher, but it’s best to consult with a professional HVAC company like Bob’s to help you determine the nuanced role each of these criteria plays. 

Below, we explore SEER ratings in-depth so you can continue your research and make an informed decision that balances cost, comfort, and environmental responsibility. Keep reading!

What Is an AC SEER Rating?

SEER ratings are calculated by dividing the total cooling output (measured in BTUs) during a cooling season by the total electrical energy input (measured in watt-hours) used during that period. A more efficient air conditioning unit will have a higher SEER rating, with most modern air conditioners ranging from 13 to 21.

6 Reasons Why SEER Ratings Matter

Reason 1: Energy Efficiency   

Higher SEER ratings indicate greater energy efficiency, so air conditioners can provide more cooling output for the same amount of energy input. Efficient units operate more economically, saving you money and energy in the long run.

Reason 2: Cost Savings

Although air conditioners with higher SEER ratings often have more significant upfront costs, they can result in significant long-term savings on energy bills. In many cases, the savings help offset the initial price difference over the unit's lifespan, which can add up substantially. 

Selecting a higher SEER-rated air conditioner is a wise financial investment because it’s designed with quality in mind, lasts longer, and requires fewer repairs. This results in a better value over time and more reliable performance.

Reason 3: Environmental Impact

More efficient air conditioners consume less energy, reducing their carbon footprint and helping conserve natural resources. Your unit will use less energy to produce the same cooling effect as a unit with a lower SEER rating. By reducing greenhouse gas emissions, you're saving money and contributing to a healthier planet.

Reason 4: Improved Comfort

Higher SEER ratings are often paired with more advanced features like variable-speed compressors and blowers, which provide more consistent cooling, better humidity control, and quieter operation. Particularly during the hot summer months, it’s nice not to be interrupted by a noisy AC unit whenever it turns on or off.

Reason 5: Compliance with Regulations

The U.S. Department of Energy has set minimum SEER rating requirements for new air conditioners. As of 2023, the minimum SEER rating is 14 in the Northern part of the United States and no less than 15 in the South. Ensuring your air conditioner meets or exceeds these regulations is important for compliance and efficiency.

Reason 6: Performance in Extreme Conditions

SEER ratings are calculated based on standard conditions (82°F outdoor temperature). However, units with higher SEER ratings generally perform better in more extreme temperatures, and let’s face it, it’s getting hotter every year in the Pacific Northwest

SEER Ratings Are Only One Piece of the Cooling Puzzle

While SEER ratings are critical in choosing an air conditioner, they shouldn't be the only consideration. Proper sizing, quality installation, and regular maintenance are also essential for your cooling system's overall efficiency and performance. Bob’s Heating & Air Conditioning can handle all of those details for you, and we look forward to the opportunity to provide an AC solution that will fit your needs.
