I dont know the exact age of my home but is somewere between 20 and 30 years. It has the orginal air conditioning system installed during construction. As a home owner I have had to make repairs and do improvments all at my own expense. But this need for a replacement air conditioner is out of my reach. I simply dont have that kind of money. I am currently unemployed and only my wife works. My wife has some kind of medical problem that has existed since childhood. I dont know the name of it but it has something to do with not sweeting propley. She has had several operations over the years. Not to cure the problem, I dont think there is a cure. But to deal with problems that have been caused by the no sweeting . I really need a air conditioner, my wife needs it.
