14 SEER vs. 13 SEER: What's the Difference?

Edited by Huma Saeed || By Sara Rehman || Published on February 6, 2024
14 SEER (Seasonal Energy Efficiency Ratio) air conditioners are more energy-efficient than 13 SEER units, resulting in slightly lower energy costs.

Key Differences

The 14 SEER rating indicates a higher level of energy efficiency in air conditioning systems compared to 13 SEER. This means that a 14 SEER unit uses less energy to provide the same amount of cooling as a 13 SEER unit.
