I am considering a duel fuel setup in Raleigh, NC, Possibly natural gas furnace with a Heat pump. This was recommended by a Trane dealer. When comparing a Trane XR12 heat pump to a standard XR12 split ac, is there any difference in how cold the evaporator coil gets during the cooling cycle? Will both the heat pump and the split AC system be equally effective at moisture removal during the cooling cycle? I am also considering a VS blower setup.
