Efficiency matters more than many homeowners realize. High-efficiency AC systems cost more upfront, but the monthly energy savings typically more than offset that initial investment over time. To make an informed decision, it helps to understand how efficiency is measured.
What Is SEER?
Modern air conditioners are rated using a SEER (Seasonal Energy Efficiency Ratio) number. SEER measures the total cooling output of a system over an entire cooling season divided by the electricity it consumes. The higher the SEER rating, the more efficient the unit. This differs from the EER rating, which measures efficiency over a single test rather than a full season.
What SEER Rating Should You Look For?
To earn the U.S. Department of Energy’s ENERGY STAR label, an AC unit must have a minimum SEER rating of 14. High-efficiency systems typically score in the 21 to 22 SEER range. As a general rule, higher SEER ratings come with higher upfront costs, but the energy savings allow the unit to pay for itself over time.
Should You Always Choose the Highest SEER?
Not necessarily. Efficiency is just one factor. A high-SEER unit won’t perform well if it’s the wrong size for your home. Be sure to work with a professional who can evaluate all the relevant factors, including system size, home layout, and insulation, before making a decision.
