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 suits a typical insulated room of roughly 33 to 40m²; sun exposure and ceiling height move that band. 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.
The Mitsubishi Electric MSZ-AP 5kW uses 368 kWh annually for cooling under the official GEMS test for Sydney's climate zone, achieving a 4-star energy rating. For heating, the system consumes 746 kWh per year and carries a 2.5-star rating. These figures reflect real-world performance in Sydney conditions and will determine your running costs when combined with current local electricity rates.
Efficiency is measured by AEER for cooling at 3.78 and ACOP for heating at 3.70. The system uses R32 refrigerant. Your actual energy consumption may vary depending on how often you run heating versus cooling, your preferred temperature settings, and how well your home is insulated and sealed.

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. We give fixed quotes by phone or email, and photos of the wall, the outdoor spot and your switchboard get you the sharpest number.
What size room does a 5kW air conditioner suit?
A 5kW split system suits roughly 32 to 40 square metres in a typical insulated room. 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?
Official government test figures for Sydney's climate zone put the Mitsubishi Electric MSZ-AP 5kW at 368 kWh a year for cooling, which works out to about $128 a year at the current Sydney median electricity rate, and about $259 a year for heating. Your bill depends on your tariff and usage, but these are the registered figures, not estimates we made up.
Is the Mitsubishi Electric MSZ-AP 5kW reverse cycle?
Yes. The registered model (MSZ-AP50VGKD2) heats and cools, so one system covers Sydney summers and winters. Its official heating figures for this climate zone are shown in the energy section above.
