HVAC Repair Service: Responding to a homeowner's concern about a ductless mini-split system emitting strange noises, our examination identified a malfunctioning fan blade. Swiftly replacing the fan blade and conducting a thorough check, we eliminated the noises. The system now operates quietly and efficiently, providing optimal climate control and a more serene indoor environment for the homeowner.
Tech preformed CMA INSPECTION on 1 Package Heat Pump. System does operate at this time, but only in cool mode and heat mode. Auxiliary Heat an Emergency Heat do not operate at this time. Tech found heat strips to be wired incorrectly from installation. Low voltage wires are not connected to low voltage terminals on contactor. This does not allow for proper communication between control board and heat strips. Tech also found a fuse on high voltage side has failed. This also causes heat strips not to operate. Heat strips do have continuity. Tech recommends correcting wiring for heat strips and replacing failed fuse. Tech also recommends pulling heat strips to clean dust and debris from them after correcting power challenges. This will help prevent any smoke and fire hazards before activating heat strips. Office will have to contact customer with pricing at a later date. Tech has attached system performance report to invoice along with pictures.
