I had my meeting to price out a new central air unit. It's going to hurt, but I'm going to do it anyway. The new unit will be 40% more efficient and will be probably be under parts and labor warranty for as long as I'm likely to own this house. It will also have humidity control which the current unit lacks and, in my mind, is practically mandatory for any sort of forced air unit.
Oh and the tax breaks and stimulus money? Yeah he told me not to expect any. In order to qualify for federal dollars I'd need an insane SERE rating. State money is limited by funded and the money is almost always spent by now. About all I can expect is a tax deduction come next April.
