Air Conditioner Energy Efficiency Ratings

The energy star most efficient 2020 designation recognizes the most efficient products among those that are energy star certified.

Air conditioner energy efficiency ratings.

The more efficient the air conditioning system the higher the number with a minimum rating of 13. Eer energy efficiency ratio shows how much electricity the system needs to run at 95 f outside and maintain 80 f with 50 humidity inside. The minimum standard seer for air conditioners is 13 though most modern air conditioners have a seer that ranges from 13 to 21. The ratio is measured in british thermal units btu per hour.

The seer is defined as the total cooling output in british thermal units or btu provided by the unit during its normal annual usage period divided by its total energy input in watt hours during the same period. This is the ratio of cooling capacity to the power input or how well it cools compared to how much energy it needs. Seer stands for seasonal energy efficiency ratio commonly referred to incorrectly as seasonal energy efficiency rating a seer rating is the ratio of the cooling output of an air conditioner over a typical cooling season divided by the energy it consumed in watt hours. The higher the eer the more efficient the unit.

The efficiency of air conditioners is often rated by the seasonal energy efficiency ratio seer which is defined by the air conditioning heating and refrigeration institute in its 2008 standard ahri 210 240 performance rating of unitary air conditioning and air source heat pump equipment. Trane air conditioners range from 14 5 seer up to 22 seer. The units are equipped with advanced features such as the aero quiet ii system and sound levels are super quiet. While the federally regulated minimum seer rating for an air conditioner is 13 or 14 depending on where you live the ranking goes as high as 25.

Higher energy efficiency a higher seer rating provides greater energy efficiency in certain conditions. Energy efficient units start from the standard 14 seer rating and can reach up to 22 seer which is the best for high efficiency and handy for saving on those electricity bills. However determining the right seer for your new a c unit isn t as straightforward as choosing a specific number. Seer shows a unit s efficiency as the temperature in your area changes each season.
