If you’ve been considering purchasing a new A/C, choosing one that is energy efficient can go a long way towards reducing your monthly expenses. To ensure you get the most bang for your buck, it’s vital that you understand what the efficiency rating you see on a different systems means. Get the scoop on SEER, EER and COP so you can make an informed decision that will help you find the an A/C that will keep your home comfortable, while saving you money.

What Does SEER, EER and COP Mean?

Your air conditioner is an important investment in your home. By having a basic understanding of A/C efficiency ratings, you’ll be equipped with knowledge that can result in huge monetary savings:

SEER (Seasonal Energy Efficiency Ratio)

The SEER for a system is determined by taking the cooling output BTUs during an average cooling season and dividing that amount by the total electrical energy input watt-hour in the same time period. The higher the system’s SEER rating, the more energy efficient it is. The minimum SEER rating today’s A/Cs can have is 13.

EER (Energy Efficient Ratio)

Like a SEER, an EER indicates the ratio of cooling output BTUs to electrical energy input watt-hours, but instead the figure being based on the cooling season, it is based on a system’s efficiency at a given point during its operation. System’s with an EER of 11.6 or higher will function more effectively during hot weather.

COP (Coefficient of Performance)

The COP is a measurement of how much power input to a system versus how much power output is produced by that system. Most A/Cs have a rating between 2 and 4. The higher the COP, the more efficient it is.
