AIRCON SIZING CALCULATOR

What is a BTU?

A BTU or British Thermal Unit is a measurement of how much energy is required to raise the temperature of one pound of water by one degree. That might not sound useful when it comes to aircons in your home or business but the underlying calculation is very important to staying comfortable.

Each ac unit or heater is rated to produce a certain number of BTUs.There are many factors that go into calculating BTUs, so we have put together a set of tools to help with air conditioner sizing.

Note: It is recommended to use an air conditioner one size bigger than the calculated BTU.
