I think it is normal process. I have heat pump from Husky heat pumps manufacturer and there were no problems before. I know that If something happens I can call to support and they will fix the defect. Maybe you also must call to your support and tell them about it.

What heat pump do you have? Maybe you must call for that company that installed it?

The most common reason for this is a completely normal cycle of operation called Defrost Cycle. During cold weather operation, ice will form on the outdoor coil. The unit senses this buildup and automatically goes into a defrost cycle. The “steam or smoke” is just water vapor from the melting ice. The noise is the reversing valve operating. After a few minutes, the fan will start up and the unit will go back into heating mode.
