I had one go out a few weeks ago. The outdoor unit would kick on but the fan wouldn't run. I know it's the capacitor. But I have no way to verify and there's an elderly woman who needs air in the house.
Call for service. $275 and 20 minutes later, the new capacitor is installed. Definitely need to keep a couple of them on hand.
$275, another gouge job, that should be a $125-150 repair, file a notice on Angies list or BBB about the high rates...
