An air conditioner’s efficiency is measured in SEER. SEER stands for Seasonal Energy Efficiency Ratio. A unit’s SEER is calculated by dividing the unit’s cooling output over an average cooling season by the amount of electric energy input over the same period.

The higher the SEER rating, the more efficient the air conditioner. The minimum SEER allowed by law for newly manufactured air conditioner is 13 or 14, depending on where in the country you live. The most efficient air conditioners on the market have SEER ratings of around 22.
