SEER rating is one of the most important numbers to understand when buying a new air conditioner, and it directly affects your energy bills.
Here’s what you need to know:
SEER Measures Seasonal Efficiency
SEER stands for Seasonal Energy Efficiency Ratio, and it measures how efficiently an air conditioner converts electricity into cooling over an entire cooling season. The rating is calculated by dividing the total cooling output by the total energy consumed during that time.
Higher Numbers Mean Better Efficiency
A higher SEER rating means the air conditioner uses less electricity to produce the same amount of cooling. For example, an 18 SEER system uses significantly less energy than a 14 SEER system to cool your home to the same temperature, which translates directly into lower utility bills.
Minimum Requirements Vary By Location
As of 2023, new air conditioners in North Carolina must have a minimum SEER rating of 14.3 because we’re in the Southeast region, where air conditioning usage is high. Units with SEER ratings of 16, 18, or even 20+ are available for homeowners who want maximum efficiency.
Upfront Cost Versus Long-Term Savings
Higher SEER units cost more to purchase and install, but they save money on electricity bills over time. The longer you plan to stay in your home and the more you use your AC, the more worthwhile it is to invest in a higher SEER rating.
Other Factors Affect Actual Efficiency
Your actual energy savings depend on more than just SEER rating, including proper system sizing, quality installation, ductwork condition, home insulation, and regular maintenance. Even the highest SEER system won’t perform efficiently if it’s poorly installed or maintained.
