which wall split air conditioner

Use our handy calculator, which will help you figure out exactly what size of unit you require for your office or home.

What is the size of the place you want to cool?

Length (m):   Width (m):   Height (m):

How many people and heat sources are in the room?

People:   Devices (PCs, Monitors, Printers etc):

    Total: BTUs of cooling required  

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.
