Seasonal Energy Efficiency Ratio [new] Official

Technically, SEER is calculated by taking the total cooling output of a system over a typical cooling season and dividing it by the total electric energy input during that same period. The SEER Scale: What’s a "Good" Number?

That night, as sweat beaded on her upper lip and the portable fan did little more than stir the thick air, Elara opened her laptop.

It was the grace to provide perfect comfort without violence, without waste, without apology. Technically, SEER is calculated by taking the total
