What size room will a 5kW air conditioner cool?

By Kyle Rafter  - May 01, 2025

Generally speaking, a 5kW air conditioner will cool between a 20 to 35 sqm size room. However, there are a number of factors that may affect this, such as which way your windows are facing and whether or not your ceiling is insulated. 

Feel free to use the Fujitsu Assist Tool, to get a rough guide of which air conditioner will suit your room size requirements. However, it's always best to get a licensed air conditioning technician to come and measure your room size to make sure you get the correctly sized air conditioner for your home.
