Air conditioner energy efficiency ratings are changing. Up till the 31st of December 2022, we using the SEER rating to determine the energy efficiency of air conditioners. From the 1st of January 2023 onward, the SEER rating will be replaced by the SEER2 rating. We are going to look at wh...

What’s the Difference Between CEER and EER? What about SEER? EER has been used to measure the efficiency of many home appliances since the rating was started in 1975. For a window air conditioner, EER is measured under certain conditions: Outside temperature of 95F, inside target temperature...
Obviously, in real-life conditions, different air conditioners will perform differently. That’s why additional metrics such as SEER and CEEP have been introduced. EER is mostly used for room air conditioners, SEER for central air conditioners, and CEEP forwindow airconditioners’ energy-efficiency....
The United States Department of Energy has changed the air conditioner and heat pump rating system from SEER, EER and HSPF to SEER2, EER2 and HSPF2.
An air conditioner with a high CEER rating can generate quite a lot of electricity savings. To illustrate this, let’s compare the energy usage of two 14,000 BTU window air conditioners with different SEER ratings: Case of a high CEER rated unit: LG LW1517IVSM 14,000 BTU has an extremel...
How To Measure EAEER Rating For An Air Conditioner? Calculating EER or SEER rating, for example, is quite simple since both are based on theoretical calculation. For the EER rating (Energy Efficiency Ratio), we just divide the max. cooling output (BTU/h) by max. power draw (wattage). ...
