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.
Ductless AC can also be used to supplement a central air system if a specific room or zone of your home, such as a room addition, is inadequately cooled by your main AC system. Ductless systems are highly efficient, preventing many of the cooling losses that often occur with central systems.
