I have been taking apple cider vinegar for about 3 months and have seen good results. I have asthma, and it has really helped with my breathing. It has also helped with restless legs, muscle cramps, and has really helped my stomach, and psoriasis.
Freon is the cooling agent used in most air conditioning systems. Every air conditioning system needs a refrigerant (also called a coolant) that actually creates the cool air -- that's the role of Freon. As necessary as Freon is to the optimal performance of your your air conditioner, you do not want to handle a potential Freon problem yourself.
Heat pumps primarily heat rooms, while air conditioners cool rooms. Heat pumps use the condenser to generate heat, while in an air conditioner it is used to expel heat. The coefficient of performance is always greater than one for a heat pump, while for an air conditioner it can be one or less.
