Air Conditioner Seer Rating Definition

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.

Air conditioner seer rating definition.

That s much better than let s say a 12 000 btu 1 400w air conditioner. Trane air conditioners range from 14 5 seer up to 22 seer. A higher seer rating provides greater energy efficiency in certain conditions. The minimum standard seer for air conditioners is 13 though most modern air conditioners have a seer that ranges from 13 to 21.

Eer rating in this case would be 12 000btu 1 400w 8 57. The higher the seer the higher the efficiency. Eer rating of 12 simply tells us that for every 1w of energy we provide to the air conditioner the air conditioner will give us 12 btu of cooling effect. Seer ratings are ratios derived by calculating the annual cooling output during the cooling season divided by the total electric energy input.

The total cooling output is the a c s british thermal unit per hour btu h multiplied by the number of cooling hours per day and the number of cooling days per year. The efficiency of your system can vary based on the size of your home your current ductwork and other variables. Seasonal energy efficiency ratio seer the cooling efficiency rating for air conditioners and heat pumps is seasonal energy efficiency ratio or seer. Seer stands for seasonal energy efficiency ratio.

Seer seasonal energy efficiency rating the efficiency with which central air conditioners and heat pumps produce cooling is most commonly rated according to their seer or seasonal energy efficiency rating. Seer ratings permit consumers to compare operating costs of various cooling systems and products. Minumum seer in the united states. This is a measure of the energy efficiency of the air conditioning system.

But don t forget this rating is a maximum.
