Down here in the South if it's attached to the house, it needs to be replaced. "well I can see that your unit is x years old and so is that old 12 gauge copper wire that connects it to the power panel. I suspact that you wpuld want to the do the right thing and upgrade to the correct 14 gauge wire (plus installation) right?" You'll want a duct cleaning with that to keep your family safe too...

A big add in the Yellow pages doesn't mean alot. There are replace everything companies everywhere. But if you look around enough. You find companies that know the difference between a furnace, and an evap coil.
