Help me diagnose what’s going on with my very old heat pump. I’m not sure if it’s getting power, because it doesn’t seem to turn on at all. I don’t recognize the kind of switch that’s in the box on the back of my house. Anyone have any pointers? #heatpump #hvac #electrician #homerepair

An old, weathered outdoor air conditioning unit sits against a house wall with tools placed on top and a green garden hose coiled nearby.A white outdoor electrical outlet cover is mounted on a beige wall above dry leaves and dirt, with green coiled cables and a metal box nearby.An old, rusty metal electrical box with a corroded handle and some spider webs inside is mounted on a beige wall.A hand is peeling back a dirty, worn label with electrical specifications and a wiring diagram from a mossy concrete surface.
