5 kWMitsubishi Electric MSZ-AP 5kW Split System
The 5kW Mitsubishi Electric MSZ-AP Split (model MSZ-AP50VGKD2) is sized for living rooms and master suites. As a guide, it cools a room of up to about 36 to 43 m². 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. Western sun, poor insulation and high ceilings bring it down. It sits in the lower half of the Mitsubishi Electric MSZ-AP Split range. If the space is bigger, has high ceilings or strong afternoon sun, step up to the 6kW.
Part of the Mitsubishi Electric MSZ-AP Split range, Mitsubishi Electric's split system line, in 7 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 5 kW options, see every 5kW split system ranked by running cost, or ask about supply and installation.
About $369 a year at the current Sydney median electricity rate: $122 of cooling plus $247 of heating, from the official GEMS test figures.

Mitsubishi Electric MSZ-AP 5kW: your questions
How much does a 5kW split system cost installed?
The unit is only part of the cost. Installed price depends on whether it is a straightforward back to back installation or needs longer pipe runs, wall brackets or a condenser slab, plus any electrical work at the switchboard. You get a fixed price in writing before any work starts. Photos of the wall, the outdoor spot and your switchboard help us price the job, and if it needs a look first, we book a site visit.
What size room does a 5kW air conditioner suit?
A 5kW split system cools a room of up to about 36 to 43 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. Strong afternoon sun, high ceilings or big glass areas push you toward the next size up, and oversizing wastes money on short cycling. The capacity calculator sizes your room in under a minute, and we confirm before we quote.
How much does the Mitsubishi Electric MSZ-AP 5kW cost to run?
