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!

Always a quality and reliable great product – From previous experience. We always had a great experience with Mitsubishi Electric Aircondituiners. Show details
