Ducted Air Conditioning

Zoning allows you to turn off a section of your ducted air conditioning system when not in use. The Mitsubishi Electric Zone Controller expands functionality, delivering conditioned air where you want it in the home/office. With the ability to create up to 4 or 8 separate zones, why condition air in unoccupied areas? 

With the Mitsubishi Electric Zone Controller, you can create up to 4 or 8 separate zones, giving you flexible control over which areas of your home receive conditioned air.

The right zoning configuration depends on your floor plan, lifestyle, and the capacity of your ducted system. An authorised Mitsubishi Electric dealer can assess your home and recommend the ideal number of zones to maximise comfort and energy efficiency.

Single-phase power is the standard method of electrical power distribution for residential applications, with 240 Vac. Single-phase power is also used for lighting.

Three Phase power is generally used for large capacity air conditioning units at 415 Vac.

When selecting an air conditioner, please consult a specialist to ensure the correct power supply is available.

Ducted air conditioning systems can be an energy-efficient choice when properly sized and installed. Mitsubishi Electric ducted air conditioners feature energy-efficiency ratings, measured as EER for cooling and COP for heating, that let you compare models. Optional zoning with the Mitsubishi Electric Zone Controller means you can turn off sections of the system when rooms are unoccupied. Correct duct sizing and professional installation also play an important role in maintaining efficiency over time.

Ducted systems have an outdoor unit that houses the compressor and condenser. This outdoor unit is responsible for releasing the heat extracted from the indoor air during the cooling process. The outdoor unit is positioned outside the home, in a ventilated position, ensuring efficient operation and minimising noise inside the home.

Ducted air conditioning is a discreet whole-home heating and cooling system designed to deliver consistent comfort throughout your home. An indoor unit, hidden in the ceiling space, heats or cools the air before distributing it through a network of ducts connected to vents in each room.

The system provides seamless temperature control across multiple areas of the home while keeping the main components out of sight for a clean, streamlined look. It can be controlled from a central wall controller and, with an optional Wi-Fi Controller, from your smartphone for added convenience.

Ducted reverse-cycle air conditioning — also known as a heat pump — provides both heating and cooling from a single unit. In cooling mode, the system extracts heat from inside the home and releases it outdoors. In heating mode, the process reverses: heat energy is drawn from the outside air and transferred indoors, even in cool conditions. A ducted reverse-cycle air conditioner is an efficient way to maintain comfortable temperatures in your home year-round.

The key components of a ducted air conditioning system are an outdoor unit, an indoor unit typically installed in the ceiling space, Mitsubishi Electric controls, and a range of field-supplied accessories, including air ducting to distribute air throughout your home.

Ducted air conditioning operates by drawing air from the home through a return air grille, passing it over a refrigerant coil in the indoor unit, and then distributing the cooled or heated air through a network of ducts. The ducts are positioned in the ceiling, delivering air to each room through vents or diffusers.

Ducted and bulkhead units are both ceiling mounted systems, but essentially a bulkhead system is designed to provide air conditioning to a single room whereas a ducted system provides air conditioning to multiple rooms.

Ducted air conditioning is well-suited to homes with multiple rooms or large open-plan spaces that require consistent, whole-home comfort. Unlike wall-mounted systems that condition a single room, a ducted air conditioner conditions multiple rooms via a single outdoor unit, freeing up yard space and the interior of wall-mounted units. Optional zoning also allows you to condition only the areas in use, helping to manage energy consumption. For homes where whole-home comfort is a priority, ducted air conditioning is a reliable, convenient solution.

set your preferred temperature and fan speed. If your system includes the optional Wi-Fi Controller, you can also manage settings remotely through a smartphone. When Zone Control is installed, you can direct conditioned air to specific areas of the home and turn off zones that are not in use. For day-to-day use, simply set your desired temperature and allow the system to maintain it automatically.

To help maximise comfort and energy efficiency, there are a few simple ways to get the best performance from your ducted air conditioning system:

• Use zoning to heat or cool only the areas of your home that are being used.
• Set a consistent target temperature instead of frequently adjusting the settings.
• Keep doors, windows, curtains and blinds closed while the system is operating to reduce heat transfer.
• Clean filters regularly and schedule professional servicing to help maintain peak performance.
• Ensure ductwork is properly sealed and insulated to minimise energy loss.

You can also improve efficiency by using timers or the optional Wi-Fi Control to manage operating times to fit your daily routine.

Ducted air conditioning systems use a range of temperature sensors depending on the system design and control setup. Sensors may be located within the indoor unit in the ceiling, integrated into the wall controller, or built into a zone control wall controller. Additional optional room sensors can also be installed to provide more precise temperature monitoring in specific areas of the home.

Your installer will configure the system and sensor placement to suit the layout, zoning requirements and comfort needs of your home, helping deliver more accurate and consistent temperature control throughout the space.

For an energy-efficient home during winter, ducted air conditioning can be a great choice. If you have multiple rooms or large open spaces to keep warm during winter, installing a ducted air conditioning system can have many benefits. While a wall-mounted split system or portable heater heats a single room, a ducted air conditioning system is hidden in the roof space, with ductwork to each room, allowing you to heat multiple areas of your home at once.

A ducted system can save on outdoor installation space by using a single outdoor unit, reducing the required area compared to installing multiple split systems. And inside, a ducted unit is discreet and out of the way, as the ductwork runs through the roof space to each room and does not use valuable wall or floor space, making it a very quiet and unobtrusive form of heating.

Ducted air conditioning operates by drawing air from the home through a return air grille, passing it over a refrigerant coil in the indoor unit, and then distributing the cooled (or heated) air through a network of ducts. The ducts are strategically placed in the ceiling, delivering the air to each room through vents or diffusers.

The installation of a ducted air conditioning system involves positioning the indoor unit in a central location in the ceiling and connecting it to a network of ducts that distribute cooled or heated air throughout the home. The outdoor unit is installed outside the home, in a ventilated position with interconnecting refrigerant pipes and electrical wiring to the ducted indoor unit. Professional installation is essential to ensure proper sizing, sealing, and insulation of the ductwork, as well as the correct placement of the indoor and outdoor units.

For new home builds, your installer may install the indoor unit, ductwork, refrigerant piping and electrical work before the gyprock is installed. The outdoor unit can be installed and connected later. Speak to your installer about this process.

The installer must have the appropriate Refrigerant Handling Licence (RHL) to install a ducted air conditioner.

Your nearest Mitsubishi Electric Specialist Dealer has the required RHL and can provide you with advice and a quote for the installation of a ducted air conditioner.

Ducted air conditioning can be installed in an existing home. A qualified installer will assess your roof space and determine the most suitable approach for routing ductwork and positioning the indoor unit. The process will require access to the ceiling cavity, and the installer will work to minimise disruption to your home. 

The Mitsubishi Electric PEA-M-HAA Series available in 10 – 14 kW and 16 kW models, have 2 piece construction, making them ideal for existing homes.

Ducted systems have an outdoor unit that houses the compressor and condenser. This outdoor unit releases the heat extracted from the indoor air during cooling. The outdoor unit is positioned outside the home in a well-ventilated area, ensuring efficient operation and minimising noise inside the home.

In many cases, yes, you can upgrade your air conditioner. Existing ductwork may be compatible with a new ducted air conditioner, depending on its condition and the ducted air conditioner’s size and capacity. 

Keep in mind that ductwork has a thermal insulation rating (R-Value), which is a measure of the material’s thermal resistance. Higher values indicate greater efficiency and reduced load on your air conditioner, so replacing ductwork with higher-rated ductwork may be more cost-effective over time.

A qualified installer can assess your current system and advise on whether the existing infrastructure can be retained or whether modifications are required. Mitsubishi Electric Specialist Dealers are experienced in upgrades and can help identify the right solution for your home.

Zoning your ducted air conditioning system is straightforward with the Mitsubishi Electric Zone Controller. Here’s how to get started:

1. Have Zone Control installed

Zone Control is an optional addition to your ducted system, installed by an authorised Mitsubishi Electric dealer. The Zone Controller can create up to 4 or 8 separate zones throughout your home, so speak to your installer about the best configuration for your floor plan.

2. Set up your zones

Once installed, your zones are managed through the Mitsubishi Electric controller. Each zone covers a room or area of your home — for example, living areas, bedrooms, or a home office.

3. Turn zones on or off as needed

Simply turn off zones in unoccupied areas. Cool the living areas during the day and switch to the bedrooms at night to avoid conditioning rooms that are not in use.

4. Control your zones remotely

Zone Control is compatible with the optional Mitsubishi Electric Wi-Fi Controller, so you can adjust your zones from anywhere using a smartphone app — ideal for getting your home comfortable before you arrive.
