No cool/ loud motor. Looked over entire 4 head mini split system. Between apt a and apt b. 3 of the 4 fan motors are making bearing noise while in operation. The blower motor in apt a bed room is exceptionally loud. 2 of the four heads have been cleaned but likely not fully. The other 2 have not been cleaned in some time. The condenser should be cleaned as well. There is debris starting to build up on the coil. The condenser coil can be cleaned during a normal maintenance at no extra charge. The indoor heads would need to be disassembled and thoroughly cleaned. This is a separate charge due to high amount of labor involved. Office will need to source motors and availability on 3 blower motors. Both in apt be and the kitchen unit in apt a. Office to contact owner with estimate for repair. I added quotes for maintenance program and for 4 mini split head cleanings. System cooling at this time.
