Hi Guys, Wondering if anyone could recommend me/or have had any good experiences with any air-conditioning servicing companies/contractors. It's for my PPOR in north-east Adelaide and it's a ducted reverse-cycle system. Noise and vibration coming from the unit in the ceiling, only when in cooling mode. Had a similar issue previously and it turned out to be one of the damper motors at a ductwork junction which I ordered the part and replaced myself. This time it's coming from the unit itself which is beyond my home handyman expertise Thanks in advance.
