What does a higher Seasonal Energy Efficiency Ratio (SEER) rating indicate about an A/C system?

A higher Seasonal Energy Efficiency Ratio (SEER) rating indicates that an A/C system is more energy-efficient. The SEER rating measures the cooling output of a system over a typical cooling-season divided by the total electric energy input during the same period. Therefore, a higher SEER rating reflects a system that uses less energy to produce a unit of cooling, leading to lower operational costs and an overall more efficient performance.

Energy efficiency is crucial for both reducing energy bills and minimizing the environmental impact since less energy consumption can lead to fewer greenhouse gas emissions associated with electricity generation. This makes systems with higher SEER ratings particularly attractive to consumers looking to balance performance with energy conservation.
