Arrived on site to perform furnace maintenance on 2016 Trane heater. Upon arrival Virginia stated that she has no questions at this time and system has been operational. Performed for maintenance on system. Filter is in good condition at this time. Cleaned flame sensor off. Hot surface igniter is good. Indoor blower motor has significant oil leakage. Gas line does not have drip leg, this unit was installed by another company. Temperature Rise is in range. Discussed full maintenance with Virginia and she is aware of indoor blower motor leaking oil. She would like to hold off on the repair at this time due to her spending a lot of money last visit. Will email over recommendation and upon departure unit is operational
