buy. However, if you like them stay away from this unit since the noise affects them more. I am that neighbour , one of two that are affected by this unit. Their Mitsubishi R32 12.5kw keeps us awake during the NIGHT, and wakes us again when its turned on at 6am. No more peaceful sleep ins for us anymore. Consider your neighbours before buying this unit.

story home.
I referred all family, friends and my community to Mitsubishi reverse ducted and I also fitted out my grandmothers 2 story home with a Mitsubishi reverse ducted in 2021.
I purchased my New Mitsubishi PEA-M140HAA-ZM(3) on 30 September 2025 to replace my PEH 6K 3 and sadly, its not cooling several rooms.
Example:- I turn bed 1,2,3 upstairs on and living downstairs off. Result. I have 2 extremely hot bedrooms and 1 lovely, cool master bedroom. Note even though living zone is switched off downstairs the air still comes out, so in my mind this could be the problem?
I cannot have anyone stay as the smarts in my new system turns the other bedrooms 2 & 3 cooling off when my master bedroom hits ambient temperature - example 23 degrees cool on 3 fan speed 3 bedrooms on only.
Master hits ambient very quickly so the 2 spare bedrooms simply circulate room temperature warmed air.
I was advised the only way to cool the bedrooms together is to try and put my master on at 19 which will not be possible as my master is freezing at 23.
The other solution I was provided was turn the downstairs living and upstairs bedroom 2 on when 1 person stays which means my master and bedroom 3 remain hot and what happens if 2 guests stay, as I cannot have living and 2 bedrooms on.
My old Mitsubishi 14Kw system had no smarts and it worked like an absolute dream throughout the house it was either on or off “no ambient shut down system” no smarts. If I had 2 guests stay I would simply turn bed 1,2,3 on and all rooms were extremely cool and comfortable.
I am so disappointed with this New model M140HAA-ZM(3) and require a solution from Mitsubishi to turn the smarts off so I can run 3 bedrooms (which are all very close together in proximity). Michael Smith said this would be possible for the manufacture to alter. I am still awaiting a resolution.
Perths summer this year has been up to 42 where I have not been able to offer any guest stay, as the bedrooms are as hot as outside.
It was 38, 38, 40 the past 3 days unbearable!

faulty from the start. Fuji techs first tried to tell me it wasn't a Fuji system. ThThedecided it was....Then took 3 weeks to replace the controller, sending out a guy who literally had never seen one before and had worked at the company for a month. It still doesn't work. At best it provides on/off function, I have 5 zones and none of them operate properly. 2 rooms where it pumps out air - even when they're turned off - while the rest of the house nothing happens. 100% not recommended.

We replaced our 20 year old Panasonic ducted air-conditioning system in October 2025 with another Panasonic system and we also added AirTouch5 Zone… Read more
controller, 5 zones all with zone temperature sensors. We initially had mixed feelings about the system when initially installed. It heated really well, however once setpoint temperature was reached and AC compressor cut out we got a cold breeze. AirTouch Support has been excellent providing expert advice regarding best configuration settings for AirTouch. I also contacted Panasonic support regarding the comfort issues.
In summary, thank you to Mannix Air-conditioning and Panasonic for the excellent customer service and support. Mannix liaised with Panasonic regarding Panasonic’s options for further customisation of settings for Panasonic indoor unit. Changes were made to installation which initially used default settings, settings were customised to work well with Airtouch 5 zoning. Since the customisation of settings I no longer have cold drafts during heating, house very comfortable. This system is now working extremely well and we are very pleased we purchased another Panasonic ducted airconditioning with NanoeX air purifier.
I highly recommend the Panasonic airconditioning incorporating 3rd party Airtouch5 zoning setup to anyone looking for complete whole of house heating and cooling with NanoeX air purifier.

was initially turned on. Needless to say the Actron repair team arrived within the week to replace the board and test the system prior to the install team returning to completed the balancing and setup. I would have thought that the board woud have been fully tested in the factory prior to fitting. Maybe something Quality Control could look at. Despite this setback the system works beautifully and provides great temperature control through the individual zones fitted with the NEO Zone Sensors. The APP also works a dream. Also allows for running individual zones rather than the full system which reduces the electrical demand and hence decreases running costs.

Dakin Premium Inverter absolute rubbish as it failed in less than 7 years – Crispair convinced us to buy an Daikin ducted air conditioner as it was a supposed to be a good ducted system and to also pay extra for the premium… Read more
Daikin inverter. The compressor has apparently failed after 6 years and nine months which is outside the 5 year warranty on compressor. Repair is almost $5000 with no guarantee that it won’t require more parts when they repair it or that something else won't fail. Given the failure, I must say that the Daikin premium is an absolute rubbish air conditioning product and 10 year warranty is worthless when compressor fails. Replacement system is expected to be $8000+ (installed) with new manufacturer warranty so I can not see any benefit in trying to have it repaired. The Daikin inverter should have lasted at least double the time it has, given information about inverters. This was purchased in late 2017 so no supply issues but obviously just cheap parts sold at premium price. Daikin may have once been good but their Premium Inverter is rubbish as far as I am concerned which seems to be the case with other reputable manufactures who also produce rubbish products. They all keep reducing cost until the product is absolute rubbish and at the same time throw away their once great reputation for producing high quality products. Also if this failure was unusual or unexpected, you think the company offer some assistance to maintain its reputation but nothing

cold often( Bathurst nsw). When outside ambient temperature gets too cold system goes into defrost mode an inbuilt function of the electric systems. so basically when I want to use my heater the most like in the morning I can't because it craps itself and says its too cold to warm up. I then have to wait until outside temperature gets high enough so it can start working again. By that time we have all left the house for work and school. Rang the local installer company that put it in and all I got was a lesson on how to use it and if it keeps not working I can book a maintenance call. Still not working and what the point of the call out when they have installed an inadequate system. A so called local and professional with over 20 years experience. I guess it is all on me for not being a professional myself and doing my research. Sad day when you can't trust a local in a small community. Absolute joke of a system that doesn't do its job.

was too big to fit in my roof. He mentioned that the new ME range looked very good on paper, so I did my homework and settled on the new ME 18kW unit.
This turned out to be a great decision, it's been operational now for a week and I am very impressed!
Firstly the outside noise is remarkably low. When my wife came home after it had been running for a couple of hours for damper testing etc, I walked her up to the unit and she felt the breeze from the fans about the same time she heard it was working. I have since been able to turn it on in the wee hours without waking her - the outside unit is just outside the bedroom. Even when it's working hard the noise level is remarkably good.
On paper, this also has the lowest indoor noise levels of the units I looked at, and 4 speeds though I am not sure that the AirTouch 5 controller knows that. The specs for COP and EER are also very good and the low power consumption while the unit is running back that up.
The unit starts gently and slowly ramps up to get the temperature to the desired point then gently ramps down to just maintain the temperature.
The weather has been mostly middling so not a real test, I plan to update this review once summer kicks in for real.

and Cooling, recommended a replacement Toshiba RAV-GM1601DTP-A whole house ducted split reverse cycle system, which could be installed without replacing all the existing ducting in the roof spaces. The installation was completed quickly and efficiently, the workers were friendly and they did their job very well. The new Toshiba RAV-GM1601DTP-A system has now been working for more than a week and we can report that this system works much better than the previous Brivis system. Air flow throughout the house is better and power consumption has decreased significantly. Previously on a 30 degree day the Brivis system would use approx. 40 KWH per day, The new Toshiba system uses only 25 KWH to do a better job. we are very happy with both the new system and the company who installed it. Thanks Toshiba Thanks Melbourne heating and Cooling
Update It is now approx.12 months since this unit was installed. We have been through a winter and summer and the unit behaves flawlessly. the power consumption is significantly less than the previous on especially during summer. Thankfully we now also have solar panels on the roof to cover power during the sunny days.

We have had the unit running now for over 12 months and haven't had a problem with it. We get lots of positive remarks about how cool and warm our house is when we have visitors. With a 6 year warranty I feel very comfortable with the purchase. I highly recommend Gree to everyone and have had one installed at my parents house since. They are also extremely happy with their unit.

How do Ducted AC’s work?
The cooled (or heated) air originates from one central location where the air conditioner has been installed, usually in the roof, and is sent throughout the house through a system of ducts.
The ducted air conditioner is connected to the house's power supply by an electrician. Due to the complex and vast nature of a ducted air conditioner, the system must be installed by a professional. Most ducted systems offer reverse cycle air conditioning, which means they have cooling and heating functions.
You might notice in a shopping centre that the whole space, including every individual store is a consistent temperature. This is because most large buildings, such as shopping centres and libraries, use a ducted air conditioning system to keep the temperature uniform.
However, ducted air conditioners don’t always have to be kept at the same temperature in every section of the house. For spaces such as homes and offices, you can independently adjust the temperature in each room - these are called air zones.
Air zones are controlled via a master controller, individual controller or through an app you can download on your phone. Individualised air zones offer convenience and energy-saving options. For example, empty rooms can be turned down to a low temperature and then back up again when it’s in use. A premium ducted system will have motion sensors which can automatically adjust the temperature when someone leaves or enters the room to prevent energy wastage.
How much does ducted air conditioning cost?
Ducted air conditioners have more expensive installation and running costs than other air conditioner systems, such as split system air conditioners but they are also far more powerful.
A ducted AC unit on its own will cost around $1,000 to $8,000 but when factoring in installation costs they can range from around $5,000 to $15,000, depending on the size of your house. It’s also important to factor in maintenance costs into your budget, such as general maintenance and repairs, in addition to hiring a duct cleaning service. Some ducted air conditioners are self-cleaning but that will only do so much. It’s important to get them thoroughly cleaned every few years to ensure they are working at their optimum capacity.
Sift through the filters on the left and read through consumer reviews to continue searching for the best air conditioner.
