What is SEER?

SEER stands for Seasonal Energy Efficiency Ratio. This rating is used to measure your unit’s efficiency at producing cool air. The SEER is calculated by dividing the amount of cool air produced by the amount of electricity used. The more efficient the unit, the higher the score will be.

An older model will produce anywhere from 150,000 to 250,000 pounds of greenhouse gases in its lifetime. Switching to an AC with a higher SEER can cut those numbers in half.
