Jake has been trying to repaie the old unit but I say its time for a new one, My Aunt was a wise woman, I can still remember some of her quotes, one is from Mat.9"16, "Don't put new patche an old garment.". TYhis unit is 17 years old, most last only 10 years before they keep failing. So owning a home is expensive. We were told by meter reader man that power company will finance and put on monthly bill. For small interest rate. Anyone know anything about this, other than more money and work put into this? I do not want to be without heat or AC .
