Tech revived to problem call for entire home. System is approximately 4 years old and zoned for 3 levels in home. Customer expressed that system was not heating and only emergency heat was working. Inspected system. Turned on heat on all levels and verified proper zoning/dampers are operational. No bypass damper or DATS. No indication that the outdoor unit was running. Indoor portion of home has inadequate flood protection. Checked outdoor unit. Found unit out on high pressure lockout. Reset heat pump and watched operations. Found that the high side pressures were extremely high on system. Previous tech in January of 2025 added 2 pounds of refrigerant, removed two pounds of refrigerant to get system pressures within specs, removed refrigerant without charging homeowner, per management. Roughly 370/100 with 45 degree outdoor ambient. System stabilized and continued heating without going into fault or lockout. Made recommendations to customer. Customer declined all options at this time.
