Please provide Make and model of furnace and AC outdoor unit.

Expert:  Phil replied 1 year ago.

Hello, if your system happens to be a heat pump, it sounds like the 24volt coil on the reversing valve went bad, or that circuit is open.

If you can get the brand name and model number of the outside unit for me and tell me a lot about your technical skill sets, I will be able to help you more efficiently.

We can go from there.
