Today we showed up for a possible 45 evaluation on a heat pump system upon arrival the outdoor unit was not running trip lock sensor was red plugged up gauges and even with the system off it was showing close to 600 PSI on the high side and like 200 PSI on the low side indicating a restriction we witnessed it turn on and try to run for exactly one second about 10 different times as I was on the phone with my Superior discussing options the system turned back on and actually ran the head pressure came down just under 400 PSI and the subcool and superheat are ideal everything is running and cooling at this moment no repair was made no additional fee other than the service call we are talking this up to a floating restriction most likely migrated oil from the condensing unit discussed options for rx11 flush and recovery and replacement of all refrigerant with the homeowner however she has chosen not to go this route at this time
