Mitsubishi SRK-ZJ Series

4 years of quiet operation – I've had 2 systems installed for 4 years now. The outside unit is so quiet it doesn't sound like it's on. This is good because it's close to neighbour's windows. The inside unit is also quiet, however, at different times my wife finds it too noisy for getting off to sleep. This is strange because I'm the one who is sensitive to noise. Just depends… Read more

I guess on the type of noise and how you're feeling at the time? The heating and cooling functions have worked faultlessly. It feels like the system doesn't have to work hard to do it's job.

Disappointing - not recommended – I bought two Mitsubishi Heavy Industries A/Cs within the last two years, one for the lounge (SRJ60ZJX) and one for the workshop, a SRK35ZJ-S.

So beware, this product does not use vermin-proof material, so if you live in the tropics or elsewhere with lots of bush life and/or vermin, there is a good chance that your brand new air conditioner will be eaten from the inside out!

Also, both air conditioners are quite noisy when on medium to high speed.

Sorry, but will not buy this product ever again - in this day and age, foam used in appliances must be vermin proof. It works, for now. The parts are not vermin-proof. Not recommended for tropics.

The head unit is quiet and and the outside unit is so quiet I often wonder if its on! I liked… Read more
