Air Conditioner Reviews usually take BTU and EER numbers into account. BTU stands for British Thermal Units, and these numbers can range from 5,000 to 18,000. The higher the BTU of an air conditioner, the more powerful it is at cooling. But it also increases the cost of the air conditioner. Normally, the BTU of an air conditioner required for cooling a room is calculated by multiplying the square foot area of the room by 35.
EER stands for Energy Efficiency Ratio. These numbers indicate the amount of energy they consume. An air conditioner with a higher EER will use less energy and hence will save money on electricity bills. EER numbers range from 8.2 to 10.5.
