Found thermostat setting incorrect. Thermostat was set for heat strip only. I changed that and tested all components and amp draws. I found no other issues today. Heat pump and heat strips working as they should at departure. Upstairs thermostat display is acting up a bit so I let customer know and if it presents any further issues that we would have to order thermostat and return with new thermostat. Informed customer of water heater condition. Customer will need contacted to set up plumbing inspection visit to check it out and get the water heater fixed before issues occur.
