Air Conditioner Calculator

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

What are the room dimensions?

How many people and heat sources are in the room?

What is a BTU?

A BTU (British Thermal Unit) is a rating used to determine the heating or cooling capacity of your Air Conditioner.

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.
