Every air conditioner comes with a SEER2 rating, which stands for Seasonal Energy Efficiency Ratio. In plain terms, it tells you how much cooling you get for the amount of electricity the system uses. The higher the number, the more efficient the unit.
Older systems often rate around 8 to 10, while new models start at SEER2 14.3, which is the federal minimum in Oklahoma. For most Norman homes, a SEER2 15 to 17 unit is a great fit, it keeps bills down without the steep price tag of ultra-high efficiency systems. If you're planning to stay in your home long-term and want maximum comfort and savings, SEER2 18 to 20+ systems are available too.
