2/12/25 Need to return tomorrow during the day to further troubleshoot the heat pump. Arrived to no heat. Found that the propane tank fueling the propane furnace was empty. Customer called and has the tank filled while the technician was there. The heat pump was going out on high pressure because it was trying to go into defrost mode and auxiliary heat was not turning on due to lack of propane. Technician was able to get the propane furnace to run and tried to check the heat pump as well. Heat pump was running while the auxiliary heat was also running. Need to return tomorrow during the day to further troubleshoot this issue. System is running on propane heat and heating the home upon departure. Faulty thermostat was the cause of the issues. Replaced the thermostat under P&L warranty. Performed function check in heating, emergency heating and cooling. System running and heating the home upon departure.
