Daikin Skywall 8.5kW Split System

Model FTXC85A

The 8.5 kW Daikin Skywall Split System cools a room of up to about 61 to 71 square metres as a guide. That is from Mitsubishi Heavy Industries' sizing chart for an insulated room: the larger figure if it faces north, the smaller if it faces east. Sun exposure, ceiling height and insulation move those figures, which is why we confirm sizing before we quote.

Part of the Daikin Skywall Split System range, Daikin's split system line, in 5 sizes. Running costs below use the Sydney median rate; the Eastern Suburbs and Western Sydney pages cost systems on their own network tariffs. Check the size against your rooms, compare it with other 8.5 kW options, see every 8kW split system ranked by running cost, or ask about supply and installation.
