Inside unit is very quiet; only noticeable when fan speed increases. Outside unit unbelievably quiet. The sound is drowned out by my barbecue burners!
Installation was quick and easy though it is not a particularly neat job.
The inside unit is just a white lump, not particularly objectionable but certainly not stylish.

Relatively cheap for the size

Tested during the recent winter days, heater performs well adequate.

The size of the indoor unit is massive and not like the latest slim line model from other brands.

Big advantage I guess was it able to throw air over longer distance to the other side of the living area.

Still need to see how it will handle over 40 degrees heat in the next summer.

Excellent Machine 3 Inside units 2.2Kw and one 2.5Kw unit.

This unit supplies air to 4 separate head units, (4 Bedrooms) Very quiet and very easy to use, The inside units I have are 3x MSZ-GE22VAD-A1 and 1 MSZ-GE25VAD-A1.I have used both cooling and heating, it’s very quick at cooling or heating the rooms and I was surprised at the power bill when it came in, I was a bit worried that we would have a massive bill but to my surprise it was so much less than expected, I would certainly recommend Mitsubishi Air conditioning for anyone wanting a good and economical to run unit for their home or business.
