Is SEER and EER the same?
The difference between EER and SEER is the “S”, which stands for seasonal. Rather than measuring the energy efficiency of an air conditioner at one operating temperature, SEER is the calculation of how energy efficient the air conditioner is during the cooling season at varying temperatures.
What does EER stand for?
Energy Efficiency RatioEER stands for Energy Efficiency Ratio. EER values are commonly used when looking at the energy efficiency of smaller window units. The EER will not give you an accurate representation of your future energy bills, but it can provide a good way to compare two systems.
Is a higher EER rating better?
The air conditioner EER is its British thermal units (BTU) rating over its wattage. … The higher the rating is, the more efficient the air conditioning unit is. However, a higher rating is usually accompanied by a higher price.
What is a good SEER rating for an air conditioner?
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. Trane air conditioners range from 14.5 SEER up to 22 SEER. But don't forget — this rating is a maximum.
