14 SEER and 15 SEER refer to Seasonal Energy Efficiency Ratio levels, with 15 SEER being more energy-efficient than 14 SEER.
14 SEER vs. 15 SEER

Key Differences

14 SEER (Seasonal Energy Efficiency Ratio) represents a moderate level of energy efficiency for air conditioning systems. In contrast, 15 SEER indicates a higher efficiency level, meaning the unit uses less energy for the same cooling output.
