The battery may not be completely dead; it is possible for it to have a problem that lets it put out normal voltage for a light load, but not be able to crank the engine. Pray that that's so, because that's about as inexpensive a problem as you can have.
How old is your home A/C? They're usually good for 10-15 years...
Jay, the A/C unit was not new when I *bought* my home--and that was nearly 10 years ago. Believe me, I'm not just idly speculating when I say that it's on its last legs.
Yeah. You should probably go ahead and bite the bullet now, as the price won't get any cheaper. I would strongly recommend spending the money on a R-410 (Puron)-based system, as it will be much cheaper to maintain in the long run as R-22 is phased out. As for efficiency, the best suggestion I can make is to factor the cost difference against your electricity bills, and see where the numbers play out. Don't forget to ask about any rebates your electric utility may be offering; those often offset the extra cost of the higher efficiency unit.
I would, but a unit big enough to supply the central air to my home costs about $2,000, and I just don't have it. Ah well, the warm season's nearly over here in Pennsylvania, and 2006 will be another year....
