I've been having issues like the heat pump not heating. Now that it's hot outside, my A/C isn't working. Can someone tell me if my Nest thermostat is even wired correctly?
If it helps any, here is how the original one was wired and it worked just fine.

Here are things to check first: - Check the 220V breaker serving the heat pump. - Check the over-pressure valve breaker on the heat pump.
