I seem to think its undercharged also, just cannot understand why, if the unit was factory charged for 15ft and I have a 14ft line set with no fittings I shouldn't be adding refrigerant.
Anyone run into an undercharged unit from the factory? I usually install Lennox or Goodman, this is my first Nordyne. I also noticed very little rushing noise when opening the service valves...
