I repaired a Trane XR16 heat pump in Chapel Hill this morning. First, I replaced the dual capacitor with a Titan Pro 40/5 uf capacitor. Next, I flushed the refrigerant lines and installed a new Trane BAYFTXV filter drier. After pulling a deep vacuum, I charged the system with 4 lbs of R-410A refrigerant per manufacturer specs. Finally, I verified proper operation by checking suction and head pressures.
