I am looking for advise here.
I have a Mitsubishi ducted heating and cooling units. One in the roof upstairs and one in the suspended ceiling downstairs. When the units are on the upstairs floor is vibrating.
I have rang the installer but he has no idea what causes this vibration, he suspects it may be a faulty fan but not sure.
Does anyone have any suggestions or recommendations what to do next?

That's up to you. They could certainly look at it for you but won't be covering installation defects which could be found to be the cause of your vibration. You can't get the original installer out to look at it? How old is the system?

I'd be getting the original installer out to look at it. It could be something as simple as the indoor unit wasn't installed with spring mounts to dampen/eliminate the vibration when the unit is running.
If you getting no where with the installer, go through your builder and put it down as a defect.
