The management company contacted the company to service 15 ductless mini split systems at the VA building located at 1105 Angelino. Reliable’s team performed a spring tune-up on all units, including Fujitsu Halcyon ductless mini-split systems with indoor units on living room walls and condensers outside at ground level behind the apartments. Tech inspected electrical components and controls, checked evaporator and condenser coils, drain lines, and drain pans, cycled compressors, blower motors, blower wheels, and condenser fan motors, checked refrigerant levels and temperature differential, and tested each system in heating and cooling modes. Dirty washable filters were found and cleaned; systems were charged with refrigerant as needed; coils were deep-cleaned where necessary; and proper operation was verified. All serviced systems are operational at this time.
