Energy Efficient Air Conditioner

Mitsubishi Electric Advanced Inverter Technology provides high-speed cooling and heating with extra energy savings compared to non-inverter models.

Quiet operation

A “Quiet Mode” setting has been added to the fan speed settings, ensuring super quiet operation as low as 18dB*. Perfect for the bedroom; it’s so quiet you’ll check to see if it’s on.

*Model 25 in heating mode only.

Night Mode

Night Mode reduces the brightness of the operation indicator light, disables beep noises, and limits the noise level of the outdoor unit.

Dual barrier coating

Developed by Mitsubishi Electric, Dual Barrier Coating designed to reduce dust and greasy dirt from collecting in the unit, providing long-lasting protection to the heat exchanger, fan and air ducts. Another feature invented by Mitsubishi Electric.

R32 refrigerant

R32 is a refrigerant with just one-third the global warming potential of R410A, meaning reduced risk of harm to the environment.

Wi-Fi Control

This innovative technology connects your domestic Mitsubishi Electric air conditioners to your smartphone, tablet or online account, giving you the freedom to fully control each unit on-the-go via an Internet connection. Optional additional adapter MAC-568IF-E required per unit.

Award winning design

The MSZ-AP Series has a uniform, streamlined design regardless of the size and model of the unit. The simple yet high-quality appearance is designed to blend in with any interior. When mounted, the units appear smaller due to the tapered bottom end. The design was recognised with a Red Dot product design award.

New vertical and horizontal vane design

New vertical and horizontal vanes are double the size of the previous model, allowing the airflow direction to be adjusted and improving airflow control effectively. These functions can be activated at the touch of a button on your remote controller.

i-save Mode

the “i-save” Mode is a simplified setting function that recalls the preferred (preset) temperature at the press of a button on the remote controller. The function ensures the most suitable air conditioning settings are used contribute to reduced power consumption.

Long airflow

The high-power motor combines with the “Long” mode to push air out further, helping to provide a more even air conditioned experience in the room. (models 60/71/80)

Blue fin condenser

Anti-corrosion treatment has been applied to the heat exchanger of the outdoor unit. This coating slows the corrosion process of the aluminium fins; this is caused by salt in the air especially in coastal areas. (Corrosion of the heat exchanger will affect efficiency and performance.)

Demand response capable*

Based on connection of a demand response enabling device (DRED), AP series unit can directly receive signals to the on board terminal block to activate Demand Response Mode. Demand Response Mode is activated in response to signals sent from the electric power company at times when it is necessary to reduce peak demand. (2.5 kW – 7.8 kW).
