Trane propane furnace with heat pump installed in 2015. All electrical connections and safeties are tight and working as they should. Ecm blower motor is acceptable. Blower wheel and evaporator coil are clean. Customer did not have a filter and it needs to be changed soon. Gas flow and igniter are in range and working as they should. Heat exchanger is acceptable. Compressor and condenser fan motor are in hood wiring order. Condenser fan motor is a little loud, the technician checked the bearings and found no side to side movement. All amp draws are acceptable. Refrigerant levels are in range. Highly suggest adding a drain safety switch to protect from water damage.
