c system, I believe it is a Rheem, has been heating the house fine all of this winter no problem. With this last recent cold spell, I turned on the heat and all that is blowing from the vents is air that feels a few degrees warmer than the air in the house, it does very slowly start to raise the temperature in the house but is taking a very long time. I have stopped using the heat for fear of damaging the inside and outside units, need help

I would call someone that knows how to check the pressure in the outside unit. I would run emegency heat if it gets to cold. Switch the thermostat from heat to emergency. If the outside unit was running when the temperature was to cold and not going into defrost it could have caused a leak in the outside unit.
The outside unit and the emergency heat are two separate heating systems the emergency heat is electric heat banks in the furnace that work in extreme situations. Check the breakers on the air handler/furnace and the breakers for the furnace to see if this will get you emergency heat. The outside unit shouldn't run with the thermostat set to emergency heat.
