what does an outside temp of 35 deg. and dropping do to a unit that uses a fan to remove heat at the condenser? Increase, decrease efficiency? nothing at all? as prescribed?

Decreasing atmospheric temperature will increase efficiency due to a higher ΔT between the hot refrigerant gas (not liquid) and the atmosphere giving higher heat exchange rates between the refigerant and the inside air.

Depends on if you are using the unit to cool your house or to heat it. If the unit is being used to cool your house (I don't know why you would do that if its 35 degrees) then cooler outside temp will help condense the warm liquid refrigerant coming into the condensor, which will make it more efficient and save electricity. If you have a heat pump condensor and you are using this unit to heat your house then the opposite holds true. The colder it gets outside, then the harder it will be for your condensor to heat your house.

Nothing at all. If the safety switch has not shut it down, you will have already frozen -up the evaporator coil inside .
