Hi all.
I've got a couple of fujitsu multi systems (Aot30lmaw4) with 4 heads on each system.
These systems are bringing complaints of loud noises from the indoor units.
The systems have been installed for 2-3 years now and i have been called back every winter since.
They only seem to cause a problem on heat mode.
Fujitsu keep asking for pipe run lengths and cable sizes (Kind of like they are denying any issue- or its an install problem)
I have seen the noises only once, (they seem to ocuur worst at night) and the indoor units were vibrating and causing panels to rattle.
Customers still reckon they get worse than what i've seen/heard
Can anyone offer advice to what i do next????
I have spent many hours on these units with no pay, and Fujitsu don't want to know about it.
Any help would be much appreciated.
