We’ve also included definitions of some common air conditioning terms. Contact us if you would like us to add one that we’ve missed.

Moisture Removal
Measured in pints per hour, this rates the air conditioner’s dehumidifying capability.
 1.2–4.2 pints/24 hours
Air Circulation (CFM)
The amount of air that moves past a stationary point in one minute. Measured in cubic feet per minute.
 250–300 ft3/min
Cooling Capacity
Air conditioner capacities are rated in Btu per hour. This is the measurement used to match your cooling or heating needs with an air conditioner. Btu stands for British Thermal Unit, which is the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit.
 7800–15600 Btu/hr
Heating Capacity
Air conditioner capacities are rated in Btu per hour. This is the measurement used to match your cooling or heating needs with an air conditioner. Btu stands for British Thermal Unit, which is the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit.
 7300–11000 Btu/hr
EER
The Energy Efficiency Ratio measures how efficiently an air conditioner will operate when the outdoor temperature is 95°. The ratio is calculated by dividing the cooling capacity (Btu/h) by the power needed to run the unit (watts). The higher the EER, the more efficient the air conditioner and the less costly it is to operate.
 8.5–9.9
