What is a BTU?
A BTU (British Thermal Unit) is a rating used to determine the heating or in the case of an Air Conditioner the cooling capacity of an appliance.
Typically a minimum of 7000 BTU is needed to cool a small room, whereas commercial units can reach up to 25,000 BTU and beyond. Simply, the greater the BTU, the larger the space that the unit can cool.
