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.
Function of air conditioner. That picture shows an air conditioner which only takes air from the inside (red indoor air arrow) and cools it before pushing it back into the room. It only uses air from outside to cool the outside condenser coils. Since you are moving heat from inside the room to outside - the outside coils will get hot and so you have to cool them.
