Arrived on site to perform furnace diagnostic on 2008 York heater. Arrived on site and Alejandro stated that the unit has been non-operational for about a week. Client states that no service or maintenance has been done in a very long time and he just wants to get the furnace fixed at this moment. Begin diagnostic at indoor unit and found a system was powered on but not igniting. Found that hot surface igniter has failed and is no longer igniting gas on ignition. Indoor blower motor has significant oil leakage as well which can lead to failure in heating and cooling when this worsens. System does not have surge protection. Air conditioning was recently added on. Discussed full diagnostic and condition with Alejandro and he’s aware of failure points within the unit. Alejandra does not want to replace unit at this time and would only like to get the mandatory repair done. He will need to have to think about the maintenance plan but does not want to agree to sign up at this time. Advise
