Welcome! We keep going until you have all of the information you need.[b/]. Extensive training & coaching also available.
I need the brand and model number of the heat pump in order to look it up.
Tell me if you have a multi meter and some skill with it so that I know what trouble shooting approach might work best.
We can go there.

Thanks.
If the outside unit humms for 3 to 5 seconds then waits and tries again in half an hour or so, it is most likely a bad compressor run capacitor.
If it is not a bad run run capacitor it would most likely be a bad compressor motor winding.
Depending on what instruments you want to buy in the $50 range each you have the option of testing or replacing it.

Look that over please and let me know if it is the outside unit that humms or if it is something else such as the the blower in the air handler inside the house.
We can go from there.
